Amendments to the 2018 International Building Code
The following sections, paragraphs, and sentences of the 2018 International Building Code are hereby amended
as follows: Standard type is text from the IBC. Underlined type is text inserted. Lined through type is deleted text
from IBC. A double asterisk (**) at the beginning of a section identifies an amendment carried over from the 2015
edition of the code and a triple asterisk (***) identifies a new or revised amendment with the 2018 code.
**Section 101.4; change to read as follows:
101.4 Referenced codes. The other codes listed in Sections 101.4.1 through 101.4.8 and referenced elsewhere
in this code, when specifically adopted, shall be considered part of the requirements of this code to the prescribed
extent of each such reference. Whenever amendments have been adopted to the referenced codes and
standards, each reference to said code and standard shall be considered to reference the amendments as well.
Any reference to NFPA 70 or the Electrical Code shall mean the Electrical Code as adopted.
(Reason: Legal wording to recognize locally adopted codes and amendments adopted with referenced codes.
The former ICC Electrical Code is now Appendix K of this code but no longer called by that name.)
**Section 101.4.8; add the following:
101.4.8 Electrical. The provisions of the Electrical Code shall apply to the installation of electrical systems,
including alterations, repairs, replacement, equipment, appliances, fixtures, fittings and appurtenances thereto.
(Reason: This was dropped when ICC quit publishing the ICC Electrical Code, but the Electrical Code still should
be referenced regardless of how it is adopted.)
** Section 103 and 103.1; amend to insert the Department Name
DEPARTMENT OF BUILDING SAFETY CITY OF COLLEYVILLE BUILDING INSPECTIONS
DEPARTMENT
103.1 Creation of enforcement agency. The Department of Building Safety City of Colleyville Building
Inspections Department is hereby created and the official in charge thereof shall be known as the building official.

Accessory structures, fences and shade cloth structures would require a permit for commercial properties to
ensure compliance with local ordinance, egress, accessibility, flame spread of fabric, wind/snow design load, etc.)
**Section 109; add Section 109.7 to read as follows:
109.7 Re-inspection Fee. A fee as established by city council resolution may be charged when:
1. The inspection called for is not ready when the inspector arrives;
2. No building address or permit card is clearly posted;
3. City approved plans are not on the job site available to the inspector;
4. The building is locked or work otherwise not available for inspection when called;
5. The job site is red-tagged twice for the same item;
6. The original red tag has been removed from the job site.
7. Failure to maintain erosion control, trash control or tree protection.
Any re-inspection fees assessed shall be paid before any more inspections are made on that job site.
(Reason: This fee is not a fine or penalty but is designed to compensate for time and trips when inspections are
called for when not ready.)
**Section 109; add Section 109.8, 109.8.1, 109.8.2 and 109.9 to read as follows:
Amendments to the 2018 International Building Code 4
109.8 Work without a permit.

without first obtaining a permit, a special investigation shall be made before a permit may be issued for such
work.
109.8.2 Fee. An investigation fee, in addition to the permit fee, shall be collected whether or not a permit is
subsequently issued. The investigation fee shall be equal to the amount of the permit fee required by this
code or the city fee schedule as applicable. The payment of such investigation fee shall not exempt the
applicant from compliance with all other provisions of either this code or the technical codes nor from penalty
prescribed by law.
109.9 Unauthorized cover up fee. Any work concealed without first obtaining the required inspection in violation
of Section 110 shall be assessed a fee as established by the city fee schedule.
(Reason: This fee is not a fine or penalty but is designed to compensate for time and to remove incentive to
attempt to evade permits and code compliance. Text taken from former Uniform Administrative Code.)
***Section 110.3.5; Lath, gypsum board and gypsum panel product inspection; Delete exception
Exception : Gypsum board and gypsum panel products that are not part of a fire resistance rated assembly or a
shear assembly.
(Reason: Lath or gypsum board inspections are not typically performed in this area.)
***Section 202; amend definition of Ambulatory Care Facility as follows:
AMBULATORY CARE FACILITY. Buildings or portions thereof used to provide medical, surgical, psychiatric,
nursing or similar care on a less than 24-hour basis to individuals who are rendered incapable of self-preservation
by the services provided or staff has accepted responsibility for care recipients already incapable. This group may
include but not be limited to the following:
- Dialysis centers
- Sedation dentistry
- Surgery centers
- Colonic centers
- Psychiatric centers
(Reason: To clarify the range of uses included in the definition. [Explanatory note related to Ambulatory Care
Facilities: This group of uses includes medical or dental offices where persons are put under for dental surgery
or other services. Section 903.2.2 will now require such uses to be sprinklered if on other than the floor of exit
discharge or if four or more persons are put under on the level of exit discharge. Recommend (1.) jurisdictions
document any pre-existing non-conforming conditions prior to issuing a new C of O for a change of tenant and,
(2.) On any medical or dental office specify on C of O the maximum number of persons permitted to be put under
general anesthesia. It is recommended that before a Certificate of Occupancy is issued, a letter of intended use
from the business owner shall be included and a C of O documenting the maximum number of care recipients
incapable of self preservation allowed.)
**Section 202; add definition of Assisting Living Facilities to read as follows.
ASSISTED LIVING FACILITIES. A building or part thereof housing persons, on a 24-hour basis, who because
of age, mental disability or other reasons, live in a supervised residential environment which provides personal
care services. The occupants are capable of responding to an emergency situation without physical assistance
from staff.
(Reason: The code references Assisted Living facilities and definition was deleted.)
Amendments to the 2018 International Building Code 5
**Section 202; change definition of “Atrium” as follows:
ATRIUM. An opening connecting two three or more stories… {Balance remains unchanged}
(Reason: Accepted practice in the region based on legacy codes. Section 1019 permits unenclosed two story
stairways under certain circumstances.)
***Section 202; add amend definition of “Repair Garage” as follows:
REPAIR GARAGE. A building, structure or portion thereof used for servicing or repairing motor vehicles. This
occupancy shall also include garages involved in minor repair, modification and servicing of motor vehicles for
items such as lube changes, inspections, windshield repair or replacement, shocks, minor part replacement and
other such minor repairs.
(Reason: The code references aligns with fire code.)
**Section 202; amend definition of SPECIAL INSPECTOR to read as follows:
SPECIAL INSPECTOR. A qualified person employed or retained by an approved agency who shall prove to the
satisfaction of the registered design professional in responsible charge and approved by the Building Official as
having the competence necessary to inspect a particular type of construction requiring special inspection.
(Reason: The registered design professional in responsible charge should be included.)
**Section 202; amend definition to read as follows:
HIGH-RISE BUILDING. A building with an occupied floor located more than 75 55 feet (22 860 mm) (16 764
mm) above the lowest level of fire department vehicle access.
(Reason: To define high-rise, as it influences sprinkler requirement thresholds based on the fire fighting
capabilities of a jurisdiction.)
***Section 303.1.3; add a sentence to read as follows:
303.1.3 Associated with Group E occupancies. A room or space used for assembly purposes that is associated
with a Group E occupancy is not considered a separate occupancy except when applying the assembly
requirements of Chapters 10 and 11.
(Reason: To clarify that egress and accessibility requirements are applicable for assembly areas, i.e. cafeteria,
auditoriums, etc.)
**Section 304.1; add the following to the list of occupancies:
Fire stations
Police stations with detention facilities for 5 or less
(Reason: Consistent with regional practice dating back to the legacy codes.)
**Section 307.1.1; add the following sentence to Exception 4:
4. Cleaning establishments… {Text unchanged} …with Section 707 or 1-hour horizontal assemblies constructed
in accordance with Section 711 or both. See also IFC Chapter 21, Dry Cleaning Plant provisions.
(Reason: To call attention to detailed requirements in the Fire Code.)
**Section 403.1, Exception 3; change to read as follows:
Amendments to the 2018 International Building Code 6
3.The open air portion of a building [remainder unchanged]
(Reason: To clarify enclosed portions are not exempt.)
**Section 403.3, Exception; delete item 2.
(Reason: To provide adequate fire protection to enclosed areas.)
**Section 403.3.2; change to read as follows:
[F] 403.3.2 Water supply to required fire pumps. In buildings that are more than 420 120 feet (36.5 m) in
building height, required fire pumps shall be supplied by connections to no fewer than two water mains located in
different streets. Separate supply piping shall be provided between each connection to the water main and the
pumps. Each connection and the supply piping between the connection and the pumps shall be sized to supply
the flow and pressure required for the pumps to operate.
Exception: {No change to exception.}
(Reason: The 2009 edition of the IFC added this requirement based on a need for redundancy of the water supply
similar to the redundancy of the power supply to the fire pumps required for such tall buildings, partially due to the
fact that these buildings are rarely fully evacuated in a fire event. More commonly, the alarm activates on the floor
of the event, the floor above and the floor below. Back-up power to the fire pump becomes critical for this reason.
Certainly, the power is pointless if the water supply is impaired for any reason, so a similar requirement is provided
here for redundant water supplies. The 2015 edition changed the requirement to only apply to very tall buildings
over 420 ft. This amendment modifies/lowers the requirement to 120 ft., based on this same height requirement
for fire service access elevators. Again, the language from the 2009 and 2012 editions of the code applied to any
high-rise building. This compromise at 120 ft. is based on the above technical justification of defend-in-place
scenarios in fire incidents in such tall structures.)
**Section 404.5; delete Exception.
(Reason: Consistent with amended atrium definition.)
**Section 406.3.3.1 Carport separation; add sentence to read as follows:
A fire separation is not required between a Group R-2 and U carport provided that the carport is entirely open
on all sides and that the distance between the two is at least 10 feet (3048 mm).
(Reason: Simplifies the fire separation distance and eliminates the need to obtain opening information on existing
buildings when adding carports in existing apartment complexes. Consistent with legacy codes in effect in region
for years and no record of problems with car fires spreading to apartments as a result.)
***Table 506.2; delete sentence from table
I. The maximum allowable area for a single-story non sprinklered Group U greenhouse is permitted to be 9000
square feet or the allowable area shall be permitted to comply with Table C102.1 of Appendix C.
(Reason: To eliminate the need for Appendix C adoption and remain consistent with 6000 sq. ft. sprinklering
provision.)
Amendments to the 2018 International Building Code 7
**Section 506.3.1; add sentence to read as follows:
506.3.1 Minimum percentage of perimeter. [Existing Text remains]
In order to be considered as accessible, if not in direct contact with a street or fire lane, a minimum 10-foot wide
pathway meeting fire department access from the street or approved fire lane shall be provided.
(Reason: To define what is considered accessible. Consistent with regional amendment to IFC 504.1.)
***Section 602.1.1; add sentence to read as follows:
602.1.1 Minimum Requirements. [Existing Text to remain]
Where a building contains more than one distinct type of construction, the building shall comply with the most
restrictive area, height, and stories, for the lesser type of construction or be separated by fire walls.
(Reason: To create definite language that requires separation between dissimilar building types.)
***Section 708.4.2; change sentence to read as follows:
708.4.2 Fireblocks and draftstops in combustible construction. [Body of text unchanged]
Exceptions:
1. Buildings equipped with an automatic sprinkler system installed throughout in accordance with
Section 903.3.1.1, or in accordance with Section 903.3.1.2 provided that sprinkler protection is
provided in the space between the top of the fire partition and the underside of the floor or roof
sheathing, deck or slab above as required for systems complying with Section 903.3.1.1. Portions of
buildings containing concealed spaces filled with noncombustible insulation as permitted for sprinkler
omission shall not apply to this exception for draft stopping. [Remainder unchanged]
Reason: (The most common exception used to eliminate the need for sprinklers in concealed spaces of
combustible construction is to fill the space with noncombustible insulation. This exception was changed in 2010
to permit a 2-inch air gap at the top of the filled space. A space compliant with the permitted omission above would
allow hot gas and smoke to spread unimpeded throughout a building not provided with draft stopping. For this
reason, omission of sprinklers permitted in accordance with NFPA 13 referenced standard should not be permitted
with IBC exception requiring draft stopping in combustible construction.)
***Section 718.3; change sentence to read as follows:
718.3 Draftstopping in floors. [Body of text unchanged]
Exceptions: Buildings equipped throughout with an automatic sprinkler system in accordance with
Section 903.3.1.1. and provided that in combustible construction, sprinkler protection is provided in the
floor space.
(Reason: To remain consistent with changes in 708.4.2 code.)
***Section 718.4; change sentence to read as follows:
718.4 Draftstopping in attics. [Body of text unchanged]
Exceptions: Buildings equipped throughout with an automatic sprinkler system in accordance with
Section 903.3.1.1 and provided that in combustible construction, sprinkler protection is provided in the
attic space.
(Reason: To remain consistent with changes in 708.4.2 code.)
Amendments to the 2018 International Building Code 8
**Section 901.6.1; add Section 901.6.1.1 to read as follows:
901.6.1.1 Standpipe Testing. Building owners/managers must maintain and test standpipe systems as per NFPA
25 requirements. The following additional requirements shall be applied to the testing that is required every 5
years:
1.The piping between the Fire Department Connection (FDC) and the standpipe shall be backflushed or
inspected by approved camera when foreign material is present or when caps are missing, and also
hydrostatically tested for all FDC’s on any type of standpipe system. Hydrostatic testing shall also be
conducted in accordance with NFPA 25 requirements for the different types of standpipe systems.
2.For any manual (dry or wet) standpipe system not having an automatic water supply capable of flowing
water through the standpipe, the tester shall connect hose from a fire hydrant or portable pumping system
(as approved by the fire code official) to each FDC, and flow water through the standpipe system to the roof
outlet to verify that each inlet connection functions properly. Confirm that there are no open hose valves
prior to introducing water into a dry standpipe. There is no required pressure criteria at the outlet. Verify that
check valves function properly and that there are no closed control valves on the system.
3.Any pressure relief, reducing, or control valves shall be tested in accordance with the requirements of NFPA
25.All hose valves shall be exercised.
4.If the FDC is not already provided with approved caps, the contractor shall install such caps for all FDC’s
as required by the fire code official.
5.Upon successful completion of standpipe test, place a blue tag (as per Texas Administrative Code, Fire
Sprinkler Rules for Inspection, Test and Maintenance Service (ITM) Tag) at the bottom of each standpipe
riser in the building. The tag shall be check-marked as “Fifth Year” for Type of ITM, and the note on the
back of the tag shall read “5 Year Standpipe Test” at a minimum.
6.The procedures required by Texas Administrative Code Fire Sprinkler Rules with regard to Yellow Tags
and Red Tags or any deficiencies noted during the testing, including the required notification of the local
Authority Having Jurisdiction (fire code official) shall be followed.
7.Additionally, records of the testing shall be maintained by the owner and contractor, if applicable, as
required by the State Rules mentioned above and NFPA 25.
8.Standpipe system tests where water will be flowed external to the building shall not be conducted during
freezing conditions or during the day prior to expected night time freezing conditions.
9.Contact the fire code official for requests to remove existing fire hose from Class II and III standpipe systems
where employees are not trained in the utilization of this firefighting equipment. All standpipe hose valves
must remain in place and be provided with an approved cap and chain when approval is given to remove
hose by the fire code official.
(Reason: Increases the reliability of the fire protection system and re-emphasizes the requirements of NFPA 25
relative to standpipe systems, as well as ensuring that FDC connections are similarly tested/maintained to ensure
operation in an emergency incident.)
**Section 903.1.1; change to read as follows:
903.1.1 Alternative Protection. Alternative automatic fire-extinguishing systems complying with Section 904 shall
be permitted instead of in addition to automatic sprinkler protection where recognized by the applicable standard
and, or as approved by the fire code official.
Amendments to the 2018 International Building Code 9
(Reason: Such alternative systems do not provide the reliability of automatic sprinkler protection. Most gaseous
type systems are highly susceptible to open doors, ceiling or floor tile removal, etc. However, an applicant could
pursue an Alternate Method request to help mitigate the reliability issues with these alternative systems with the
fire code official if so desired, or there may be circumstances in which the fire code official is acceptable to allowing
an alternate system in lieu of sprinklers, such as kitchen hoods or paint booths.)
**Section 903.2; add paragraph to read as follows and delete the exception:
Automatic Sprinklers shall not be installed in elevator machine rooms, elevator machine spaces, and elevator
hoistways, other than pits where such sprinklers would not necessitate shunt trip requirements under any
circumstances. Storage shall not be allowed within the elevator machine room. Signage shall be provided at the
entry doors to the elevator machine room indicating “ELEVATOR MACHINERY – NO STORAGE ALLOWED.”
(Reason: Firefighter and public safety. This amendment eliminates the shunt trip requirement of the International
Building Code Section 3005.5 for the purpose of elevator passenger and firefighter safety. This amendment is
contingent on the Building Code amendment eliminating the Exceptions to Section 3005.4, such that passive fire
barriers for these areas are maintained. The exception deletion is due to the fact that such telecom areas pose
an undue fire risk to the structural integrity of the building.)
**Section 903.2.9; add Section 903.2.9.3 to read as follows:
903.2.9.3 Self-Service Storage Facility. An automatic sprinkler system shall be installed throughout all self-
service storage facilities.
(Reason: Fire departments are unable to inspect these commercial occupancies and are unaware of the contents
being stored. Previous allowance to separate units by fire barriers is difficult to enforce maintenance after
opening.)
Section 903.2.11; change 903.2.11.3 and add 903.2.11.7, 903.2.11.8, and 903.2.11.9 as follows:
903.2.11.3 Buildings 55 35 feet or more in height. An automatic sprinkler system shall be installed
throughout buildings that have one or more stories with an occupant load of 30 or more, other than penthouses
in compliance with Section 1510 of the International Building Code, located 55 35 feet (16 764 10 668 mm)
or more above the lowest level of fire department vehicle access, measured to the finished floor.
Exceptions:
1. Open parking structures in compliance with Section 406.5 of the International Building Code,
having no other occupancies above the subject garage.
2. Occupancies in Group F-2.
903.2.11.7 High-Piled Combustible Storage. For any building with a clear height exceeding 12 feet (4572
mm), see Chapter 32 to determine if those provisions apply.
903.2.11.8 Spray Booths and Rooms. New and existing spray booths and spraying rooms shall be protected
by an approved automatic fire-extinguishing system.
903.2.11.9 Buildings Over 6,000 sq. ft. An automatic sprinkler system shall be installed throughout all
buildings with a building area 6,000 sq. ft. or greater and in all existing buildings that are enlarged to be 6,000
sq. ft. or greater. For the purpose of this provision, fire walls shall not define separate buildings.
Exception: Open parking garages in compliance with Section 406.5 of the International Building Code.
(Reason: Provides jurisdictions options as to their desired level of sprinkler protection based on multiple factors
including firefighting philosophies/capabilities.)
Amendments to the 2018 International Building Code 10
**Section 903.3.1.1.1; change to read as follows:
903.3.1.1.1 Exempt Locations. When approved by the fire code official, automatic sprinklers shall not be
required in the following rooms or areas where such ...{text unchanged}… because it is damp, of fire-resistance-
rated construction or contains electrical equipment.
1.Any room where the application of water, or flame and water, constitutes a serious life or fire hazard.
2.Any room or space where sprinklers are considered undesirable because of the nature of the contents,
when approved by the fire code official.
3.Generator and transformer rooms, under the direct control of a public utility, separated from the remainder
of the building by walls and floor/ceiling or roof/ceiling assemblies having a fire-resistance rating of not
less than 2 hours.
4.In rooms or areas that are of noncombustible construction with wholly noncombustible contents.
5.Fire service access Elevator machine rooms, and machinery spaces, and hoistways, other than pits where
such sprinklers would not necessitate shunt trip requirements under any circumstances.
6.{Delete.}
(Reason: Gives clarification. Exception 4 deleted to provide protection where fire risks are poorly addressed.
Amendment 903.2 addresses Exception 5 above relative to the elimination of sprinkler protection in these areas
to avoid the shunt trip requirement.)
***Section 903.3.1.2.3; delete sections and replace as follows:
[F] Section 903.3.1.2.3 Attached Garages and Attics. Sprinkler protection is required in attached garages, and
in the following attic spaces:
1.[Remainder Unchanged]
2.[Remainder Unchanged]
3.Attic spaces of buildings that are two or more stories in height above grade plane or above the lowest
level of fire department vehicle access.
4.Group R-4, Condition 2 occupancy attics not required by Item 1 or 3 to have sprinklers shall comply
with one of the following:
[Remainder Unchanged]
(Reason: Attic protection is required due to issues with fire exposure via soffit vents, as well as firefighter safety.
Several jurisdictions indicated experience with un-protected attic fires resulting in displacement of all building
occupants. NFPA 13 provides for applicable attic sprinkler protection requirements, as well as exemptions to such,
based on noncombustible construction, etc. Attached garages already require sprinklers via NFPA 13R – this
amendment just re-emphasizes the requirement.)
**Section 903.3.1.3; change to read as follows:
903.3.1.3 NFPA 13D Sprinkler Systems. Automatic sprinkler systems installed in one- and two-family dwellings;
Group R-3; Group R-4, Condition 1; and townhouses shall be permitted to be installed throughout in accordance
with NFPA 13D or in accordance with state law.
(Reason: To allow the use of the Plumbing section of the International Residential Code (IRC) and recognize
current state stipulations in this regard.)
**Section 903.3.1.4; add to read as follows:
[F] 903.3.1.4 Freeze protection. Freeze protection systems for automatic fire sprinkler systems shall be in
accordance with the requirements of the applicable referenced NFPA standard and this section.
903.3.1.4.1 Attics. Only dry-pipe, pre-action, or listed antifreeze automatic fire sprinkler systems shall be
allowed to protect attic spaces.
Amendments to the 2018 International Building Code 11
Exception: Wet-pipe fire sprinkler systems shall be allowed to protect non-ventilated attic spaces
where:
1. The attic sprinklers are supplied by a separate floor control valve assembly to allow ease
of draining the attic system without impairing sprinklers throughout the rest of the building,
and
2. Adequate heat shall be provided for freeze protection as per the applicable referenced
NFPA standard, and
3. The attic space is a part of the building’s thermal, or heat, envelope, such that insulation
is provided at the roof deck, rather than at the ceiling level.
903.3.1.4.2 Heat trace/insulation. Heat trace/insulation shall only be allowed where approved by the fire
code official for small sections of large diameter water-filled pipe.
(Reason: In the last few years, severe winters brought to light several issues with current practices for sprinklering
attics, not the least of which was wet-pipe sprinklers in ventilated attics provided with space heaters, etc. for freeze
protection of such piping. This practice is not acceptable for the protection of water-filled piping in a ventilated
attic space as it does not provide a reliable means of maintaining the minimum 40 degrees required by NFPA,
wastes energy, and presents a potential ignition source to the attic space. Listed antifreeze is specifically included
because NFPA currently allows such even though there is no currently listed antifreeze at the time of development
of these amendments. The intent of this amendment is to help reduce the large number of freeze breaks that
have occurred in the past with water-filled wet-pipe sprinkler systems in the future, most specifically in attic
spaces.)
**Section 903.3.5; add a second paragraph to read as follows:
Water supply as required for such systems shall be provided in conformance with the supply requirements of the
respective standards; however, every water-based fire protection system shall be designed with a 10 psi safety
factor. Reference Section 507.4 for additional design requirements.
(Reason: To define uniform safety factor for the region.)
**Section 903.4; add a second paragraph after the exceptions to read as follows:
Sprinkler and standpipe system water-flow detectors shall be provided for each floor tap to the sprinkler system
and shall cause an alarm upon detection of water flow for more than 45 seconds. All control valves in the sprinkler
and standpipe systems except for fire department hose connection valves shall be electrically supervised to initiate
a supervisory signal at the central station upon tampering.
(Reason: To avoid significant water losses. Consistent with amendment to IFC 905.9.)
**Section 903.4.2; add second paragraph to read as follows:
The alarm device required on the exterior of the building shall be a weatherproof horn/strobe notification appliance
with a minimum 75 candela strobe rating, installed as close as practicable to the fire department connection.
(Reason: Fire department connections are not always located at the riser; this allows the fire department faster
access.)
**Section 905.2; change to read as follows:
905.2 Installation Standard. Standpipe systems shall be installed in accordance with this section and NFPA 14.
Manual dry standpipe systems shall be supervised with a minimum of 10 psig and a maximum of 40 psig air
pressure with a high/low alarm.
Amendments to the 2018 International Building Code 12
(Reason: To define manual dry standpipe supervision requirements. Helps ensure the integrity of the standpipe
system via supervision, such that open hose valves will result in a supervisory low air alarm.)
***Section 905.3; add Section 905.3.9 and exception to read as follows:
905.3.9 Buildings Exceeding 10,000 sq. ft. In buildings exceeding 10,000 square feet in area per story and
where any portion of the building’s interior area is more than 200 feet (60960 mm) of travel, vertically and
horizontally, from the nearest point of fire department vehicle access, Class I automatic wet or manual wet
standpipes shall be provided.
Exceptions:
1.Automatic dry, semi-automatic dry, and manual dry standpipes are allowed as provided for in NFPA
14 where approved by the fire code official.
2.R-2 occupancies of four stories or less in height having no interior corridors.
(Reason: Allows for the rapid deployment of hose lines to the body of the fire. Manual dry option added this
edition.)
**Section 905.4, change Item 1, 3, and 5, and add Item 7 to read as follows:
1.In every required interior exit stairway, a hose connection shall be provided for each story above and below
grade plane. Hose connections shall be located at the main floor landing between stories, unless otherwise
approved by the fire code official.
2.{No change.}
3.In every exit passageway, at the entrance from the exit passageway to other areas of a building.
Exception: Where floor areas adjacent to an exit passageway are reachable from an interior exit stairway
hose connection by a {No change to rest.}
4.{No change.}
5.Where the roof has a slope less than four units vertical in 12 units horizontal (33.3-percent slope), each
standpipe shall be provided with a two-way a hose connection shall be located to serve the roof or at the
highest landing of an interior exit stairway with stair access to the roof provided in accordance with Section
1011.12.
6.{No change.}
7.When required by this Chapter, standpipe connections shall be placed adjacent to all required exits to the
structure and at two hundred feet (200’) intervals along major corridors thereafter, or as otherwise approved
by the fire code official.
(Reason: Item 1, 3, and 5 amendments to remove ‘interior’ will help to clarify that such connections are required
for all ‘exit’ stairways, to ensure firefighter capabilities are not diminished in these tall buildings, simply because
the stair is on the exterior of the building. Item 5 reduces the amount of pressure required to facilitate testing, and
provides backup protection for fire fighter safety. Item 7 allows for the rapid deployment of hose lines to the body
of the fire.)
**Section 905.9; add a second paragraph after the exceptions to read as follows:
Sprinkler and standpipe system water-flow detectors shall be provided for each floor tap to the sprinkler system
and shall cause an alarm upon detection of water flow for more than 45 seconds. All control valves in the sprinkler
and standpipe systems except for fire department hose connection valves shall be electrically supervised to initiate
a supervisory signal at the central station upon tampering.
(Reason: To avoid significant water losses. Consistent with amendment to IFC 903.4.)
Amendments to the 2018 International Building Code 13
**Section 907.1; add Section 907.1.4 to read as follows:
907.1.4 Design Standards. Where a new fire alarm system is installed, the devices shall be addressable. Fire
alarm systems utilizing more than 20 smoke detectors shall have analog initiating devices.
(Reason: Provides for the ability of descriptive identification of alarms, and reduces need for panel replacement
in the future. Updated wording to match the language of the new requirement at 907.5.2.3. Change of terminology
allows for reference back to definitions of NFPA 72.)
**Section 907.2.1; change to read as follows:
907.2.1 Group A. A manual fire alarm system that activates the occupant notification system in accordance with
Section 907.5 shall be installed in Group A occupancies where the having an occupant load due to the assembly
occupancy is of 300 or more persons, or where the Group A occupant load is more than 100 persons above or
below the lowest level of exit discharge. Group A occupancies not separated from one another in accordance with
Section 707.3.10 of the International Building Code shall be considered as a single occupancy for the purposes
of applying this section. Portions of Group E occupancies occupied for assembly purposes shall be provided with
a fire alarm system as required for the Group E occupancy.
Exception: {No change.}
Activation of fire alarm notification appliances shall:
1. Cause illumination of the means of egress with light of not less than 1 foot-candle (11 lux) at the walking
surface level, and
2. Stop any conflicting or confusing sounds and visual distractions.
(Reason: Increases the requirement to be consistent with Group B requirement. Also addresses issue found in
Group A occupancies of reduced lighting levels and other A/V equipment that distracts from fire alarm notification
devices or reduces ability of fire alarm system to notify occupants of the emergency condition.)
**Section 907.2.3; change to read as follows:
907.2.3 Group E. A manual fire alarm system that initiates the occupant notification signal utilizing an emergency
voice/alarm communication system meeting the requirements of Section 907.5.2.2 and installed in accordance
with Section 907.6 shall be installed in Group E educational occupancies. When automatic sprinkler systems or
smoke detectors are installed, such systems or detectors shall be connected to the building fire alarm system. An
approved smoke detection system shall be installed in Group E day care occupancies. Unless separated by a
minimum of 100' open space, all buildings, whether portable buildings or the main building, will be considered one
building for alarm occupant load consideration and interconnection of alarm systems.
Exceptions:
1.{No change.}
1.1. Residential In-Home day care with not more than 12 children may use interconnected single
station detectors in all habitable rooms. (For care of more than five children 2 1/2 or less years of
age, see Section 907.2.6.) {No change to remainder of exceptions.}
(Reason: To distinguish educational from day care occupancy minimum protection requirements. Further, to
define threshold at which portable buildings are considered a separate building for the purposes of alarm systems.
Exceptions provide consistency with State law concerning such occupancies.)
**Section 907.2.12, Exception 3; change to read as follows:
Amendments to the 2018 International Building Code 14
3. Open air portions of buildings with an occupancy in Group A-5 in accordance with Section 303.1 of the
International Building Code; however, this exception does not apply to accessory uses including but not limited
to sky boxes, restaurants, and similarly enclosed areas.
(Reason: To indicate that enclosed areas within open air seating type occupancies are not exempted from
automatic fire alarm system requirements.)
**Section 907.4.2; add Section 907.4.2.7 to read as follows:
907.4.2.7 Type. Manual alarm initiating devices shall be an approved double action type.
(Reason: Helps to reduce false alarms.)
**Section 907.6.1; add Section 907.6.1.1 to read as follows:
907.6.1.1 Wiring Installation. All fire alarm systems shall be installed in such a manner that a failure of any
single initiating device or single open in an initiating circuit conductor will not interfere with the normal operation
of other such devices. All signaling line circuits (SLC) shall be installed in such a way that a single open will not
interfere with the operation of any addressable devices (Class A). Outgoing and return SLC conductors shall be
installed in accordance with NFPA 72 requirements for Class A circuits and shall have a minimum of four feet
separation horizontal and one foot vertical between supply and return circuit conductors. The initiating device
circuit (IDC) from a signaling line circuit interface device may be wired Class B, provided the distance from the
interface device to the initiating device is ten feet or less.
(Reason: To provide uniformity in system specifications and guidance to design engineers. Improves reliability of
fire alarm devices and systems.)
**Section 907.6.3; delete all four Exceptions.
(Reason: To assist responding personnel in locating the emergency event for all fire alarm systems.)
**Section 907.6.6; add sentence at end of paragraph to read as follows:
See 907.6.3 for the required information transmitted to the supervising station.
(Reason: To assist responding personnel in locating the emergency event for all fire alarm systems.)
(Reason: Deleted Previous code amendment Section 909.22, For removal because it is already in the code in
Sections 909.20.5, 909.20.6, 909.20.6.1, 909.20.6.2, and 909.20.6.3.)
**Section 910.2; change Exception 2 and 3 to read as follows:
2. Only manual smoke and heat removal shall not be required in areas of buildings equipped with early
suppression fast-response (ESFR) sprinklers. Automatic smoke and heat removal is prohibited.
3. Only manual smoke and heat removal shall not be required in areas of buildings equipped with control
mode special application sprinklers with a response time index of 50(m*S)1/2 or less that are listed to
control a fire in stored commodities with 12 or fewer sprinklers. Automatic smoke and heat removal is
prohibited.
(Reason: Allows the fire department to control the smoke and heat during and after a fire event, while still
prohibiting such systems from being automatically activated, which is a potential detriment to the particular
sprinkler systems indicated.)
**Section 910.2; add subsections 910.2.3 with exceptions to read as follows:
Amendments to the 2018 International Building Code 15
910.2.3 Group H. Buildings and portions thereof used as a Group H occupancy as follows:
1. In occupancies classified as Group H-2 or H-3, any of which are more than 15,000 square feet (1394 m2)
in single floor area.
Exception: Buildings of noncombustible construction containing only noncombustible materials.
2. In areas of buildings in Group H used for storing Class 2, 3, and 4 liquid and solid oxidizers, Class 1 and
unclassified detonable organic peroxides, Class 3 and 4 unstable (reactive) materials, or Class 2 or 3
water-reactive materials as required for a high-hazard commodity classification.
Exception: Buildings of noncombustible construction containing only noncombustible materials.
(Reason: Maintains a fire protection device utilized in such occupancies where it is sometimes necessary to allow
chemicals to burn out, rather than extinguish.)
**Section 910.3; add section 910.3.4 to read as follows:
910.3.4 Vent Operation. Smoke and heat vents shall be capable of being operated by approved automatic and
manual means. Automatic operation of smoke and heat vents shall conform to the provisions of Sections 910.3.2.1
through 910.3.2.3.
910.3.4.1 Sprinklered buildings. Where installed in buildings equipped with an approved automatic sprinkler
system, smoke and heat vents shall be designed to operate automatically.
The automatic operating mechanism of the smoke and heat vents shall operate at a temperature rating at least
100 degrees F (approximately 38 degrees Celsius) greater than the temperature rating of the sprinklers installed.
Exception: Manual only systems per Section 910.2.
910.3.4.2 Nonsprinklered Buildings. Where installed in buildings not equipped with an approved automatic
sprinkler system, smoke and heat vents shall operate automatically by actuation of a heat-responsive device rated
at between 100°F (56°C) and 220°F (122°C) above ambient.
Exception: Listed gravity-operated drop out vents.
(Reason: Amendment continues to keep applicable wording from prior to the 2012 edition of the IFC. Specifically,
automatic activation criteria is no longer specifically required in the published code. Specifying a temperature
range at which smoke and heat vents should activate in sprinklered buildings helps to ensure that the sprinkler
system has an opportunity to activate and control the fire prior to vent operation.)
**Section 910.4.3.1; change to read as follows:
910.4.3.1 Makeup Air. Makeup air openings shall be provided within 6 feet (1829 mm) of the floor level. Operation
of makeup air openings shall be manual or automatic. The minimum gross area of makeup air inlets shall be 8
square feet per 1,000 cubic feet per minute (0.74 m2 per 0.4719 m3/s) of smoke exhaust.
(Reason: Makeup air has been required to be automatic for several years now in this region when mechanical
smoke exhaust systems are proposed. This allows such systems to be activated from the smoke control panel
by first responders without having to physically go around the exterior of the building opening doors manually.
Such requires a significant number of first responders on scene to conduct this operation and significantly delays
activation and/or capability of the smoke exhaust system.)
**Section 912.2; add Section 912.2.3 to read as follows:
Amendments to the 2018 International Building Code 16
912.2.3 Hydrant Distance. An approved fire hydrant shall be located within 100 feet of the fire department
connection as the fire hose lays along an unobstructed path.
(Reason: To accommodate limited hose lengths, improve response times where the FDC is needed to achieve
fire control, and improve ease of locating a fire hydrant in those situations also. Also, consistent with NFPA 14
criteria.)
***Section 913.2.1; add Section 913.2.1.1 and exception to read as follows:
913.2.1.1 Fire Pump Room Access. When located on the ground level at an exterior wall, the fire pump room
shall be provided with an exterior fire department access door that is not less than 3 ft. in width and 6 ft. – 8 in. in
height, regardless of any interior doors that are provided. A key box shall be provided at this door, as required by
IFC Section 506.1.
Exception: When it is necessary to locate the fire pump room on other levels or not at an exterior wall, the
corridor leading to the fire pump room access from the exterior of the building shall be provided with equivalent
fire resistance as that required for the pump room, or as approved by the fire code official. Access keys shall
be provided in the key box as required by IFC Section 506.1.
(Reason: This requirement allows fire fighters safer access to the fire pump room. The requirement allows access
without being required to enter the building and locate the fire pump room interior access door during a fire event.
The exception recognizes that this will not always be a feasible design scenario for some buildings, and as such,
provides an acceptable alternative to protect the pathway to the fire pump room.)
**Section 1006.2.2.7; add Section 1006.2.2.7 as follows:
1006.2.2.7 Electrical Rooms. For electrical rooms, special exiting requirements may apply. Reference the
electrical code as adopted.
(Reason: Cross reference necessary for coordination with the NEC which has exiting requirements as well.)
**Section 1009.8; add the following Exception 7:
1009.8 Two Way Communication. A two-way communication system complying with Sections 1009.8.1 and
1009.8.2 shall be provided at the landing serving each elevator required to be accessible on each accessible floor
that is one or more stories above or below the level of exit discharge.
Exceptions:
7. Buildings regulated under State Law and built in accordance with State registered plans, including variances or
waivers granted by the State, shall be deemed to be in compliance with the requirements of Section 1009 and
chapter 11.
(Reason: To accommodate buildings regulated under Texas State Law and to be consistent with amendments in
Chapter 11.)
**Section 1010.1.9.5 Bolt Locks; amend exceptions 3 and 4 as follows:
Exceptions:
3. Where a pair of doors serves an occupant load of less than 50 persons in a Group B, F, M or S occupancy.
(remainder unchanged)
4. Where a pair of doors serves a Group A, B, F, M or S occupancy (remainder unchanged)
(Reason: Application to M occupancies reflects regional practice; No. 4 expanded to Group A due to it being a
similar scenario to other uses; No. 4 was regional practice.)
Amendments to the 2018 International Building Code 17
**Section 1020.1 Construction; add exception 6 to read as follows:
6. In group B occupancies, corridor walls and ceilings need not be of fire-resistive construction within a single
tenant space when the space is equipped with approved automatic smoke-detection within the corridor. The
actuation of any detector must activate self-annunciating alarms audible in all areas within the corridor. Smoke
detectors must be connected to an approved automatic fire alarm system where such system is provided.
(Reason: Regionally accepted alternate method.)
**Section 1029.1.1.1 Spaces under grandstands and bleachers; delete this section.
(Reason: Unenforceable.)
**Section 1101.1 Scope; add exception to Section 1101.1 as follows:
Exception: Components of projects regulated by and registered with Architectural Barriers Division of Texas
Department of Licensing and Regulation shall be deemed to be in compliance with the requirements of this
chapter.
(Reason: To accommodate buildings regulated under state law. Further clarified in 2015 to mean components
that are specifically addressed by TDLR shall be exempt.)
**Section 2901.1; add a sentence to read as follows:
[P] 2901.1 Scope. {existing text to remain} The provisions of this Chapter are meant to work in coordination with
the provisions of Chapter 4 of the International Plumbing Code. Should any conflicts arise between the two
chapters, the Building Official shall determine which provision applies.
(Reason: Gives building official discretion.)
**Section 2902.1; add a second paragraph to read as follows:
In other than E Occupancies, the minimum number of fixtures in Table 2902.1 may be lowered, if requested in
writing, by the applicant stating reasons for a reduced number and approved by the Building Official.
(Reason: To allow flexibility for designer to consider specific occupancy needs.)
**Table 2902.1; add footnote g to read as follows:
g.Drinking fountains are not required in M Occupancies with an occupant load of 100 or less, B Occupancies with
an occupant load of 25 or less, and for dining and/or drinking establishments.
(Reason: Adjustment meets the needs of specific occupancy types.)
**Add new Section 2902.1.4 to read as follows:
2902.1.4 Additional fixtures for food preparation facilities. In addition to the fixtures required in this Chapter,
all food service facilities shall be provided with additional fixtures set out in this section.
2902.1.4.1 Hand washing lavatory. At least one hand washing lavatory shall be provided for use by employees
that is accessible from food preparation, food dispensing and ware washing areas. Additional hand washing
lavatories may be required based on convenience of use by employees.
Amendments to the 2018 International Building Code 18
2902.1.4.2 Service sink. In new or remodeled food service establishments, at least one service sink or one floor
sink shall be provided so that it is conveniently located for the cleaning of mops or similar wet floor cleaning tool
and for the disposal of mop water and similar liquid waste. The location of the service sink(s) and/or mop sink(s)
shall be approved by the <Jurisdiction’s> health department.
(Reason: Coordinates Health law requirements with code language for consistent regional practice.)
***Section 3001.2 Emergency Elevator Communication Systems for the deaf, hard of hearing and speech
impaired; delete this section.
(Reason: Per Elevator manufacturers input, they were not consulted prior to code approval and technology of
elevator provisions as submitted are not currently available to provide this feature.)
***Section 3002.1 Hoistway Enclosure Protection required. Add exceptions to Section 3002.1 as follows:
Exceptions:
4.Elevators completely located within atriums shall not require hoistway enclosure protection.
5.Elevators in open or enclosed parking garages that serve only the parking garage, shall not require
hoistway enclosure protection.
(Reason: Provides specific Code recognition that elevators within atriums and within parking garages do not
require hoistway enclosure protection. Amendment needed since specific Code language does not currently
exist.)
**Section 3005.4 Machine rooms, control rooms, machinery spaces and control spaces; delete text as
follows:
Elevator machine rooms, control rooms, control spaces and machinery spaces outside of but attached to a
hoistway that have openings into the hoistway shall be enclosed with fire barriers constructed in accordance with
Section 707 or horizontal assemblies constructed in accordance with Section 711, or both.
Revise text to read:
Elevator machine rooms, control rooms, control spaces and machinery spaces shall be enclosed with fire barriers
constructed in accordance with Section 707 or horizontal assemblies constructed in accordance with Section 711,
or both.
(Remainder unchanged)
(Reason: This amendment eliminates code language to be consistent with the regional goal to require passive
enclosures of these areas unless a hoistway enclosure is not required by other Code provisions. See companion
change to eliminate fire sprinklers thereby eliminating shunt trip.)
***Section 3005.4 Machine rooms, control rooms, machinery spaces and control spaces;
Delete exceptions and add two new exceptions to Section 3005.4 as follows:
Exceptions:
1. Elevator machine rooms, control rooms, machinery spaces and control spaces completely located
within atriums shall not require enclosure protection.
2. Elevator machine rooms, control rooms, machinery spaces and control spaces in open or enclosed
parking garages that serve only the parking garage, shall not require enclosure protection.
Amendments to the 2018 International Building Code 19
(Reason: This amendment eliminates the Exceptions to Section 3005.4 such that passive enclosures for these
areas are to be provided and maintained. The fire rating of these enclosures is permitted to be omitted by the
above added exceptions where allowed by other provisions of the code such as in atriums and parking structures.
See companion change to eliminate fire sprinklers to eliminate the need for shunt trip system.)
**Section 3005.7 add a Section 3005.7 as follows:
3005.7 Fire Protection in Machine rooms, control rooms, machinery spaces and control spaces.
3005.7.1 Automatic sprinkler system. The building shall be equipped throughout with an automatic sprinkler
system in accordance with Section 903.3.1.1, except as otherwise permitted by Section 903.3.1.1.1 and as
prohibited by Section 3005.7.2.1.
3005.7.2.1 Prohibited locations. Automatic sprinklers shall not be installed in machine rooms, elevator
machinery spaces, control rooms, control spaces and elevator hoistways.
3005.7.2.2 Sprinkler system monitoring. The sprinkler system shall have a sprinkler control valve supervisory
switch and water-flow initiating device provided for each floor that is monitored by the building’s fire alarm system.
3005.7.3 Water protection. An approved method to prevent water from infiltrating into the hoistway enclosure
from the operation of the automatic sprinkler system outside the elevator lobby shall be provided.
3005.7.4 Shunt trip. Means for elevator shutdown in accordance with Section 3005.5 shall not be installed.
(Reason: Firefighter and public safety. This amendment eliminates the shunt trip requirement of the International
Building Code Section 3005.5 for the purpose of elevator passenger and firefighter safety. The new section above
is intended to be identical to Sections 3007.2, 3007.3, and 3007.4 for Fire Service Access Elevators and Sections
3008.2, 3008.3 and 3008.4 for Occupant Evacuation Elevators.)
**Section 3005.8; add Section 3005.8 as follows:
3005.8 Storage. Storage shall not be allowed within the elevator machine room, control room, machinery spaces
and or control spaces. Provide approved signage at each entry to the above listed locations stating: "No Storage
Allowed.
(Reason: Reinforces the need to maintain space clean and free of combustibles. See companion change to
eliminate fire sprinklers therein, to always require an enclosure - with IBC 3005.4 exceptions deleted - resulting in
the limited need for a shunt trip system.)
Section 3006.2, Hoistway opening protection required; Revise text as follows:
5. The building is a high rise and the elevator hoistway is more than 75 feet (22 860 mm) 55 feet (16 764 mm) in
height. The height of the hoistway shall be measured from the lowest floor at or above grade to the highest floors
served by the hoistway.”
(Reason: 2018 IBC text does not address hoistways that are greater than 75’-0” in height that are both below
grade and above grade but not located above the high rise classification nor does the IBC address hoistways
wholly located above grade such as those that serve sky lobbies".)

reasonable advance notice to the building official when the piping system is ready for testing. The equipment,
material, power and labor necessary for the inspections and test shall be furnished by the permit holder and the
permit holder shall be responsible for determining that the work will withstand the test pressure prescribed in the
following tests.
(Reason: To utilize language used in the IPC regarding who is responsible for testing procedures.)
**Section G2417.4; change to read as follows:
G2417.4 (406.4) Test pressure measurement. Test pressure shall be measured with a monometer or with a
pressure-measuring device designed and calibrated to read, record, or indicate a pressure loss caused by leakage
Amendments to the 2018 International Residential Code 28
during the pressure test period. The source of pressure shall be isolated before the pressure tests are made.
Mechanical gauges used to measure test pressures shall have a range such that the highest end of the scale is
not greater than five times the test pressure.
(Reason: To require the use of more accurate diaphragm gauges. Spring gauges do not provide accurate
measurement below approximately 17 psig.)
**Section G2417.4.1; change to read as follows:
G2417.4.1 (406.4.1) Test pressure. The test pressure to be used shall be no less than 3 psig (20 kPa gauge),
or at the discretion of the Code Official, the piping and valves may be tested at a pressure of at least six (6) inches
(152 mm) of mercury, measured with a manometer or slope gauge, irrespective of design pressure. Where the
test pressure exceeds 125 psig (862 kPa gauge), the test pressure shall not exceed a value that produces a hoop
stress in the piping greater than 50 percent of the specified minimum yield strength of the pipe. For tests requiring
a pressure of 3 psig, diaphragm gauges shall utilize a dial with a minimum diameter of three and one half inches
(3 ½”), a set hand, 1/10 pound incrementation and pressure range not to exceed 6 psi for tests requiring a pressure
of 3 psig. For tests requiring a pressure of 10 psig, diaphragm gauges shall utilize a dial with a minimum diameter
of three and one-half inches (3 ½”), a set hand, a minimum of 2/10 pound incrementation and a pressure range
not to exceed 20 psi. For welded piping, and for piping carrying gas at pressures in excess of fourteen (14) inches
water column pressure (3.48 kPa) (1/2 psi) and less than 200 inches of water column pressure (52.2 kPa) (7.5
psi), the test pressure shall not be less than ten (10) pounds per square inch (69.6 kPa). For piping carrying gas
at a pressure that exceeds 200 inches of water column (52.2 kPa) (7.5 psi), the test pressure shall be not less
than one and one-half times the proposed maximum working pressure.
Diaphragm gauges used for testing must display a current calibration and be in good working condition. The
appropriate test must be applied to the diaphragm gauge used for testing
(Reason: To provide for lesser pressures to coordinate with the use of more accurate diaphragm gauges.)
**Section G2417.4.2; change to read as follows:
G2417.4.2 (406.4.2) Test duration. The test duration shall be held for a length of time satisfactory to the Building
Official, but in no case for be not less than 10 fifteen (15) minutes. For welded piping, and for piping carrying gas
at pressures in excess of fourteen (14) inches water column pressure (3.48 kPa), the test duration shall be held
for a length of time satisfactory to the Building Official, but in no case for less than thirty (30) minutes.
(Reason: To comply with accepted regional practices.)
**Section G2420.1 (406.1); add Section G2420.1.4 to read as follows:
G2420.1.4 Valves in CSST installations. Shutoff valves installed with corrugated stainless steel (CSST) piping
systems shall be supported with an approved termination fitting, or equivalent support, suitable for the size of the
valves, of adequate strength and quality, and located at intervals so as to prevent or damp out excessive vibration
but in no case greater than 12-inches from the center of the valve. Supports shall be installed so as not to interfere
with the free expansion and contraction of the system's piping, fittings, and valves between anchors. All valves
and supports shall be designed and installed so they will not be disengaged by movement of the supporting piping.
(Reason: To provide proper security to CSST valves. These standards were established in this region in 1999
when CSST was an emerging technology.)
**Section G2420.5.1 (409.5.1); add text to read as follows:
G2420.5.1 (409.5.1) Located within the same room. The shutoff valve…{bulk of paragraph unchanged}… in
accordance with the appliance manufacturer’s instructions. A secondary shutoff valve must be installed within 3
feet (914 mm) of the firebox if appliance shutoff is located in the firebox.
Amendments to the 2018 International Residential Code 29
(Reason: Reflects regional practice and provides an additional measure of safety.)
**Section G2421.1 (410.1); add text and Exception to read as follows:
G2421.1 (410.1) Pressure regulators. A line pressure regulator shall be … {bulk of paragraph unchanged}…
approved for outdoor installation. Access to regulators shall comply with the requirements for access to appliances
as specified in Section M1305.
Exception: A passageway or level service space is not required when the regulator is capable of being
serviced and removed through the required attic opening.

accordance with the code provisions in effect when installed, when approved by the Building Official unless
an unsafe condition is determined to exist as described in International Fuel Gas Code Section 108.7 of the
Fuel Gas Code.
(Reason: Gives code official discretion.)
**Section G2448.1.1 (624.1.1); change to read as follows:
G2448.1.1 (624.1.1) Installation requirements. The requirements for water heaters relative to access, sizing,
relief valves, drain pans and scald protection shall be in accordance with this code.
(Reason: To clarify installation requirements. Also corresponds with amendments regarding water heater access.)

prevent direct contact, the sheathing shall have a thickness of not less than 0.008 inch (8 mil) (0.203 mm) and the
sheathing shall be made of approved material plastic. Where sheathing protects piping that penetrates concrete
or masonry walls or floors, the sheathing shall be installed in a manner that allows movement of the piping within
the sheathing.
(Reason: Allows for other materials to be accepted.)
***Section P2603.5.1 Sewer Depth; change to read as follows:
Amendments to the 2018 International Residential Code 30
P2603.5.1 Sewer depth. Building sewers that connect to private sewage disposal systems shall be a minimum
of [number] inches (mm) below finished grade at the point of septic tank connection. Building sewers shall be a
minimum of 12 inches (304 mm) below grade.
(Reason: Provides sewer depth that is common in this region. Deleted reference to private sewage disposal
because a private sewage disposal code is not typically adopted in this region.)
***Section P2604; add to read as follows:
P2604.2.1 Plastic sewer and DWV piping installation. Plastic sewer and DWV piping installed underground
shall be installed in accordance with the manufacturer’s installation instructions. Trench width shall be controlled
to not exceed the outside the pipe diameter plus 16 inches or in a trench which has a controlled width equal to the
nominal diameter of the piping multiplied by 1.25 plus 12 inches. The piping shall be bedded in 4 inches of
granular fill and then backfilled compacting the side fill in 6-inch layers on each side of the piping. The compaction
shall be to minimum of 85 percent standard proctor density and extend to a minimum of 6 inches above the top
of the pipe.
(Reason: To follow manufacturer backfill requirements and to be clear to Inspectors out in the field.)
*** Section P2801; change to read as follows:

Where a storage tank-type water heater or a hot water storage tank is installed in a location where water leakage
from the tank will cause damage, the tank shall be installed in a pan constructed of one of the following:
1. Galvanized steel or aluminum of not less than 0.0236 inch (0.6010 mm) in thickness.
2. Plastic not less than 0.036 inch (0.9 mm) in thickness.
3. Other approved materials.
A plastic pan beneath a gas-fired water heater shall be constructed of material having a flame spread index
of 25 or less and a smoke-developed index of 450 or less when tested in accordance with ASTM E84 or UL 723.
(Reason: Plastic burns degrading material over time on gas fired water heaters and to maintaining protection
level.)

**Section P2801.6.1; change to read as follows:
Section P2801.6.1 Pan size and drain. The pan shall be not less than 11/2 inches (38 mm) in depth and shall
be of sufficient size and shape to receive all dripping or condensate from the tank or water heater. The pan shall
be drained by an indirect waste pipe having a diameter of not less than 3/4 inch (19 mm). Piping for safety pan
drains shall be of those materials listed in Table P2906.5.
Multiple pan drains may terminate to a single discharge piping system when approved by the administrative
authority and permitted by the manufactures installation instructions and installed with those instructions. {existing
text unchanged}
(Reason: Regionally accepted practice.)
*** Section P2804.6.1; change to read as follows:
Section P2804.6.1 Requirements for discharge piping. The discharge piping serving a pressure relief valve,
temperature relief valve or combination thereof shall:
1. Not be directly connected to the drainage system.
2. Discharge through an air gap located in the same room as the water heater.
Amendments to the 2018 International Residential Code 31
3. Not be smaller than the diameter of the outlet of the valve served and shall discharge full size to the air
gap.
4. Serve a single relief device and shall not connect to piping serving any other relief device or equipment.
Exception: Multiple relief devices may be installed to a single T & P discharge piping system when
approved by the administrative authority and permitted by the manufactures installation instructions and
installed with those instructions.
5. Discharge to the floor, to the pan serving the water heater or storage tank, to a waste receptor an approved
location or to the outdoors.
[remainder unchanged]
(Reason: To ensure the T&P is ran to the exterior.)
**Section P2902.5.3; change to read as follows:
P2902.5.3 Lawn irrigation systems. The potable water supply to lawn irrigation systems shall be protected
against backflow by an atmospheric-type vacuum breaker, a pressure-type vacuum breaker, a double-check
assembly or a reduced pressure principle backflow preventer. A valve shall not be installed downstream from an
atmospheric vacuum breaker. Where chemicals are introduced into the system, the potable water supply shall be
protected against backflow by a reduced pressure principle backflow preventer.
(Reason: To provide clarity.)
***Section P3003.9; change to read as follows:
P3003.9.2 Solvent cementing. Joint surfaces shall be clean and free from moisture. A purple primer that
conforms to ASTM F 656 shall be applied. Solvent cement not purple in color and conforming to ASTM D 2564,
CSA B137.3, CSA B181.2 or CSA B182.1 shall be applied to all joint surfaces. The joint shall be made while the
cement is wet and shall be in accordance with ASTM D 2855. Solvent cement joints shall be permitted above or
below ground.
Exception: A primer is not required where both of the following conditions apply:
1. The solvent cement used is third-party certified as conforming to ASTM D 2564
2. The solvent cement is used only for joining PVC drain, waste, and vent pipe and fittings in
not pressure applications in sizes up to and including 4 inches (102mm) in diameter.
(Reason: to keep the “process of joining PVC pipe”.)
**Section P3111Combination waste and vent systems; delete this section in its entirety.
(Reason: A combination waste and vent system is not approved for use in residential construction.)
**Section P3112.2 Vent Collection; delete and replace with the following:
P3112.2 Installation. Traps for island sinks and similar equipment shall be roughed in above the floor and may
be vented by extending the vent as high as possible, but not less than the drain board height and then returning
it downward and connecting it to the horizontal sink drain immediately downstream from the vertical fixture drain.
The return vent shall be connected to the horizontal drain through a wye-branch fitting and shall, in addition, be
provided with a foot vent taken off the vertical fixture vent by means of a wye-branch immediately below the floor
and extending to the nearest partition and then through the roof to the open air or may be connected to other
vents at a point not less than six (6) inches (152 mm) above the flood level rim of the fixtures served. Drainage
Amendments to the 2018 International Residential Code 32
fittings shall be used on all parts of the vent below the floor level and a minimum slope of one-quarter (1/4) inch
per foot (20.9 mm/m) back to the drain shall be maintained. The return bend used under the drain-board shall be
a one (1) piece fitting or an assembly of a forty-five (45) degree (0.79 radius), a ninety (90) degree (1.6 radius)
and a forty-five (45) degree (0.79 radius) elbow in the order named. Pipe sizing shall be as elsewhere required
in this Code. The island sink drain, upstream of the return vent, shall serve no other fixtures. An accessible
cleanout shall be installed in the vertical portion of the foot vent.
(Reason: To clarify the installation of island venting and to provide a regional guideline on a standard installation
method for this region.)
***Section P3114.3; amend to read as follows:
P3114.3. Where permitted. Individual vents, branch vents, circuit vents and stack vents serving kitchen island
vests or bar sinks shall be permitted to terminate with a connection to an air admittance valve. All other proposed
air admittance valve installations shall require prior approval by the Building Official. Individual and branch type
air admittance valves shall vent only fixtures that are on the same floor level and connect to a horizontal branch
drain.
(Reason: To identify the locations and installation compliance for air admittance valves other than kitchen islands
and bar sinks.)
**Chapters 34 through 43; delete. Replace with the electrical code as adopted.
(Reason: State law permits only the NEC.)
Note: Chapters 34 through 43 are based on the 2017 National Electrical Code and are included here for
reference only. The Electrical Code as adopted by separate ordinance takes precedence over these sections.

Amendments to the 2018 International Energy Conservation Code
The following sections, paragraphs, and sentences of the 2018 International Energy Conservation Code (IECC)
are hereby amended as follows: Standard type is text from the IECC. Underlined type is text inserted. Lined
through type is deleted text from IECC. A double (**) asterisk at the beginning of a section identifies an amendment
carried over from the 2015 edition of the code and a triple (***) asterisk identifies a new or revised amendment
with the 2018 code. Section numbers in parenthesis represent the corresponding numbers of the energy
provisions of the 2018 International Residential Code for parallel amendments.
2018 IECC (Energy Provisions of the 2018 IRC)
**Section 101.1; amend to insert the Department Name
101.1 Title. These regulations shall be known as the Energy Conservation Code of the City of Colleyville Building
Inspections Department hereinafter referred to as “this code, or “department”, and the official in charge thereof
shall be known as the Building Official.
(Reason: References the name of the jurisdiction in the general regulations.)
**Section C102/R102 General; add Section C102.1.2 and R102.1.2 (N1101.4.1) to read as follows:
C102.1.2 Alternative compliance. A building certified by a national, state, or local accredited energy efficiency
program and determined by the Energy Systems Laboratory to be in compliance with the energy efficiency
requirements of this section may, at the option of the Code Official, be considered in compliance. The United
States Environmental Protection Agency's Energy Star Program certification of energy code equivalency shall be
considered in compliance.
R102.1.2 (N1101.4.1) Alternative compliance. A building certified by a national, state, or local accredited energy
efficiency program and determined by the Energy Systems Laboratory to be in compliance with the energy
efficiency requirements of this section may, at the option of the Code Official, be considered in compliance. The
United States Environmental Protection Agency's Energy Star Program certification of energy code equivalency
shall be considered in compliance. Regardless of the program or the path to compliance, each 1- and 2-family
dwelling shall be tested for air and duct leakage as prescribed in Section R402.4.1.2 (N1102.4.1.2) and R403.3.3
(N1103.3.3) respectively.
(Reason: This amendment is added to allow alternative compliance in accordance with Texas HB 1365, 78th
Legislature. Codified in Chapter 388 Texas Building Energy Performance Standards: §388.003(i).
The last sentence to Section R102.1.2 (N1101.4.1) was added to insure that every house is tested in accordance
with the mandatory provisions of the code.)
Section R202 (N1101.6) Definitions; add the following definition:
**PROJECTION FACTOR. The ratio of the horizontal depth of the overhang, eave or permanently attached
shading device, divided by the distance measured vertically from the bottom of the fenestration glazing to the
underside of the overhang, eave or permanently attached shading device.
(Reason: The amendment to Section 402.3.2 (N1102.3.2) Glazed fenestration SHGC was proposed by the
TAB. ESL determined the proposal to be not less restrictive than the 2015 IECC. This added definition is
necessary as part of that amendment. The amendment will provide additional options for SHGC selection.)
Section R202 (N1101.6) Definitions; add the following definition:
Amendments to the 2018 International Energy Conservation Code 34
**DYNAMIC GLAZING. Any fenestration product that has the fully reversible ability to change it performance
properties, including U-factor, solar heat gain coefficient (SHGC), or visible transmittance (VT).
(Reason: This term is referenced in Section R402.3.2. This definition of DYMANIC GLAZING is also found in the
Commercial provisions of the code.)
***Table 402.1.2 (N1102.1.2) INSULATION AND FENESTRATION REQUIREMENTS BY COMPONENT; the
Fenestration U-factor for Climate Zone 3 is amended as follows:

(Reason: Carries forward the value in the 2015 IECC/IRC.)
**Section R402.3.2 (N1102.3.2) Glazed fenestration SHGC; amend by adding a paragraph and table
following the exception to read as follows:
Where vertical fenestration is shaded by an overhang, eave, or permanently attached shading device, the SHGC
required in Table R402.1.2 shall be reduced by using the multipliers in Table R402.3.2 SHGC Multipliers for
Permanent Projections.

a North oriented means within 45 degrees of true north.
(Reason: The amendment to Section 402.3.2 Glazed fenestration SHGC was proposed by the TAB and ESL
determined the proposal to be not less restrictive than the 2015 IECC. This added definition is necessary as part
of that amendment. The amendment will provide additional options for SHGC selection.)
Amendments to the 2018 International Energy Conservation Code 35
**R402.4.1.2 (N1102.4.1.2) Testing; add a last paragraph to read as follows:
Mandatory testing shall only be performed by individuals that are certified to perform air infiltration testing certified
by national or state organizations as approved by the building official. The certified individuals must be an
independent third-party entity, and may not be employed; or have any financial interest in the company that
constructs the structure.
(Reason: The 2018 International Residential Code (IRC) and International Energy Conservation Code (IECC)
includes enhanced emphasis on envelope infiltration and duct leakage. Significant changes in the residential
energy requirements include more frequent requirement of performance testing for leakage. Residential Duct
systems must be tested unless all ducts and equipment are located within the conditioned space. Envelope
testing is required to demonstrate compliance with maximum allowable leakage rate. This language puts the
regulatory authority on notice that the testing requires specialized credentials and establishes a conflict of interest
baseline.)
***Section R402.4 (N1102.4) Air leakage (Mandatory); add a new section and table to read as follows:
R402.4.1.3 (N1102.4.1.3) Testing option – ACH tradeoff. As an option to the air leakage rate set out in Section
R402.4.1.2 (N1102.4.1.2), 1- and 2-family homes meeting all of the listed criteria below and the thermal envelope
requirements in Table R402.4.1.3 (N1102.4.1.3) will be considered compliant when tested and verified as having
an air leakage rate to not less than or equal to four air changes per hour when tested and reported in accordance
with the testing standards and reporting criteria listed in Section R402.4.1.2 (N1102.4.1.2).
The compliance equivalency is limited as follows:
1.Limited to a conditioned floor area between 1,000 and 6,000 square feet,
2.Limited to between 2 to 6 bedrooms,
3.Assumes all ductwork and mechanical equipment is located in the unconditioned attic,
4.Assumes typical wood framing in the walls and roof, and
5.Assumes one of the following heating/cooling systems:
a.All electric system with a heat pump for heating, or
b.A system with electric cooling and natural gas heating.
Dwellings using electric resistance strip heating do not qualify for this tradeoff.

a Except for the values listed in the table, all other mandatory code provisions are applicable.
b The first value listed is the R-value of cavity insulation, the second value is the R-value of the continuous
insulation or insulated siding.
Amendments to the 2018 International Energy Conservation Code 36
(Reason: This provides a viable option to the single-family residential builder. The Energy Systems Laboratory
determined that this tradeoff option to be not less stringent than the residential provisions of the 2015 IECC and
the energy provisions of the 2015 IRC.)
*** Section R402.4 Air leakage (Mandatory); add a new section to read as follows:
R402.4.1.4 Testing options for R2 multifamily dwelling units. As an option to the air leakage rate set out in
Section R402.4.1.2, multifamily dwelling units will be considered compliant when tested and verified as having an
air leakage rate to the air leakage rate set out in either Section R402.4.1.4.1 or Section R402.4.1.4.2 when tested
and reported in accordance with the testing standards and reporting criteria listed in Section R402.4.1.2
R402.4.1.4.1 Total air leakage rate for interior multifamily dwelling units. Interior multifamily
dwelling units with a measured, “unguarded” total air leakage result of 5.3 ACH50 or less shall be
considered compliant.
R402.4.1.4.2 Total air leakage rate for corner multifamily dwelling units. Corner multifamily
units with a measured, “unguarded” total leakage result of less than 5.0 ACH50 shall be considered
compliant.
(Reason: The Mandatory Section R402.4 Air Leakage of the 2015 IECC requires that the building thermal
envelope be tested and verified in accordance with R402.4.1.2. Measuring air leakage for multifamily buildings
or dwelling units using an air leakage to outside test (i.e. guarded) can be costly and time prohibitive. This is
because in order to isolate leakage only through the building thermal envelope, all leakage to adjacent units
through adiabatic surfaces must be pressure neutralized. The methodology below therefore allows for the use of
total air leakage testing for multifamily dwelling units that includes air leakage to the exterior and to adjacent units
(i.e. unguarded) to show compliance with R402.4.1.2. This increases the flexibility of the code without affecting
stringency. This methodology has been approved for use by ESL, and the methodology applies only to
jurisdictions in the NCTCOG area.)
*** Section R402.4 Air leakage (Mandatory); add a new section to read as follows:
R402.4.1.5 Sampling options for R2 multifamily dwelling units. For buildings having three or more
dwelling units, a minimum of 15% of the dwelling units in each building must be tested as required by Section
R402.4.1.2. Prior to beginning sampling for testing, “Initial Testing” is required for each multifamily property.
“Initial Testing” shall consist of the 3rd party testing contractor performing the required tests on at least three
consecutive dwelling units. Test results from the “Initial Testing” must satisfy minimum code requirements
before sampling is permitted. Dwelling units selected for the “Initial Testing” must be within the same building.
Dwelling units selected for “Initial Testing” shall not be included in a “sample group” or counted toward the
minimum 15% of dwelling units tested. The building official shall randomly select the three dwelling units for
“Initial Testing.” The building official may delegate the random selection to the designated 3rd party testing
contractor.
R402.4.1.5.1 Sample group Identification and Sampling. The builder shall identify a "sample group"
which may be a building, floor, fire area or portion thereof. All of the dwelling units within the “sample
group” must be at the same stage of construction and must be ready for testing. The building official
shall randomly select at least 15% of dwelling units from each “sample group” for testing. The building
official may delegate the random selection to the designated 3rd party testing contractor.
If each tested dwelling unit within a “sample group” meets the minimum code requirements, then all
dwelling units in the “sample group” are considered to meet the minimum code requirements.
Amendments to the 2018 International Energy Conservation Code 37
Before a building may be deemed compliant with the testing as required, each “sample group” must be
deemed compliant with the minimum code requirements. The sum total of all of the tested dwelling units
across all “sample groups” shall not be less than a minimum of 15% of the dwelling units in a building.
R402.4.1.5.2 Failure to Meet Code Requirement(s). If any dwelling units within the identified “sample
group” fail to meet a code requirement as determined by testing, the builder will be directed to correct
the cause(s) of failure, and 30% of the remaining dwelling units in the “sample group” will be randomly
selected for testing by the building official, or third-party testing contractor, regarding the specific
cause(s) of failure.
If any failures occur in the additional dwelling units, all remaining dwelling units in the sample group
must be individually tested for code compliance.
A multifamily property with three failures within a 90-day period is no longer eligible to use the
sampling protocol in that community or project until successfully repeating "Initial Testing." Sampling
may be reinstated after at least three consecutive dwelling units are individually verified to meet all
code requirements.
A Certificate of Occupancy may not may be issued for any building until testing has been performed
and deemed to satisfy the minimum code requirements on the dwelling unit(s) identified for testing.
(Reason: For many multifamily (R2 classifications) projects, it is very costly and time consuming to test each
dwelling unit for projects where there may be dozens of dwelling units in each building. Considering that the
same tradesman generally constructs a building, it is reasonable to deem that construction practices are
consistent and that if a reasonable sampling of units tested pass then all units would pass. These amendments
are very similar to other ordinances/policies from Austin and San Antonio.)
** R403.3.3 (N1103.3.3) Duct Testing (Mandatory); add a last paragraph to read as follows:
Mandatory testing shall only be performed by individuals that are certified to perform duct testing leakage testing
certified by national or state organizations as approved by the building official. The certified individuals must be
an independent third-party entity, and may not be employed; or have any financial interest in the company that
constructs the structure.
(Reason: The 2015 International Residential Code (IRC) and International Energy Conservation Code (IECC)
includes enhanced emphasis on envelope infiltration and duct leakage. Significant changes in the residential
energy requirements include more frequent requirement of performance testing for leakage. Residential Duct
systems must be tested unless all ducts and equipment are located within the conditioned space. Envelope
testing is required to demonstrate compliance with maximum allowable leakage rate. This language puts the
regulatory authority on notice that the testing requires specialized credentials and establishes a conflict of interest
baseline).
*** Section R403.3 Ducts; add a new section to read as follows:
R403.3.4.1 Sampling options for R2 multifamily dwelling units. For buildings having three or more dwelling
units, a minimum of 15% of the dwelling units in each building must be tested as required by Section R403.3.3.
Prior to beginning sampling for testing, “Initial Testing” is required for each multifamily property. “Initial Testing”
shall consist of the 3rd party testing contractor performing the required tests on at least three consecutive
dwelling units. Test results from the “Initial Testing” must satisfy minimum code requirements before sampling
is permitted. Dwelling units selected for the “Initial Testing” must be within the same building. Dwelling units
selected for “Initial Testing” shall not be included in a “sample group” or counted toward the minimum 15% of
Amendments to the 2018 International Energy Conservation Code 38
dwelling units tested. The building official shall randomly select the three dwelling units for “Initial Testing.” The
building official may delegate the random selection to the designated 3rd party testing contractor.
R403.3.4.1.1 Sample group Identification and Sampling. The builder shall identify a "sample group"
which may be a building, floor, fire area or portion thereof. All of the dwelling units within the “sample
group” must be at the same stage of construction and must be ready for testing. The building official
shall randomly select at least 15% of dwelling units from each “sample group” for testing. The building
official may delegate the random selection to the designated 3rd party testing contractor.
If each tested dwelling unit within a “sample group” meets the minimum code requirements, then all
dwelling units in the “sample group” are considered to meet the minimum code requirements.
Before a building may be deemed compliant with the testing as required, each “sample group” must be
deemed compliant with the minimum code requirements. The sum total of all of the tested dwelling units
across all “sample groups” shall not be less than a minimum of 15% of the dwelling units in a building.
R403.3.4.1.2 Failure to Meet Code Requirement(s). If any dwelling units within the identified “sample
group” fail to meet a code requirement as determined by testing, the builder will be directed to correct
the cause(s) of failure, and 30% of the remaining dwelling units in the “sample group” will be randomly
selected for testing by the building official, or third-party testing contractor, regarding the specific
cause(s) of failure.
If any failures occur in the additional dwelling units, all remaining dwelling units in the sample group
must be individually tested for code compliance.
A multifamily property with three failures within a 90-day period is no longer eligible to use the
sampling protocol in that community or project until successfully repeating "Initial Testing." Sampling
may be reinstated after at least three consecutive dwelling units are individually verified to meet all
code requirements.
A Certificate of Occupancy may not may be issued for any building until testing has been performed
and deemed to satisfy the minimum code requirements on the dwelling unit(s) identified for testing.
(Reason: For many multifamily (R2 classifications) projects, it is very costly and time consuming to test each
dwelling unit for projects where there may be dozens of dwelling units in each building. Considering that the
same tradesman generally constructs a building, it is reasonable to deem that construction practices are
consistent and that if a reasonable sampling of units tested pass then all units would pass. These amendments
are very similar to other ordinances/policies from Austin and San Antonio.)
**Section C402.2/R402.2 (N1102.2) Specific insulation requirements (Prescriptive); add Section C402.2.8
and R402.2.14 (N1102.2.14) to read as follows:
Section C402.2.8/R402.2.14 (N1102.2.14) Insulation installed in walls. Insulation installed in walls shall be
totally enclosed on all sides consisting of framing lumber, gypsum, sheathing, wood structural panel sheathing or
other equivalent material approved by the building official.
(Reason: This will increase the performance of the insulation.)
Amendments to the 2018 International Energy Conservation Code 39
***Section C403.7.4 Energy recovery ventilation systems (Mandatory); add exception #12 to read as
follows:
12. Individual ventilation systems that serve an individual dwelling unit or sleeping unit.
(Reason: This will clarify the intent of the section without requiring the user or the code official to analyze the
numbers in the table. So a ventilation system that serves only an individual dwelling unit or sleeping unit does not
require an energy recovery system.)
***Section C403.11.1 Duct and Plenum Insulation and Sealing (Mandatory); is amended by adding a
second paragraph to read as follows:
Environmental ducts and plenums installed in vertical chases, both supply and exhaust, where the ducts or
plenums will not be accessible after construction completion, shall be leak tested in accordance with the SMACNA
HVAC Air Leakage Test Manual to the installed ductwork class and pressure requirements.
Documentation shall be furnished demonstrating that representative sections totaling not less than 25 percent of
the duct area have been tested and that all tested sections comply with the requirements of this section.
(Reason: Ductwork installed in chases is not accessible after construction completion. Leakage in these ducts
will increase the energy use of the buildings and systems for the life of the building and reduce the system
performance. Since the leakage in the chase enclosed ductwork would be difficult if not impossible to locate and
correct, testing at the time of installation would assure that the ducts are properly installed and efficient.)
***Section R404.1 (N1104.1); revised in its entirety to read as follows:
Section R404.1 (N1104.1) Lighting equipment (Mandatory). Not less than 75 percent of the lamps in
permanently installed lighting fixtures or not less than 75 percent of the permanently installed lighting fixtures shall
contain only high-efficacy lamps.
(Reason: This retains the 2015 language will allows for more flexibility.)
**Section 405.2 (N1105.2); add the exception to read as follows:
Section 405.2 (N1105.2) Mandatory requirements. Compliance with the section requires that the mandatory
provisions identified in Section 401.2 be met. Supply and return ducts not completely inside the building thermal
envelope shall be insulated to an R-value of not less than R-6.
Exceptions:
1. For one and two family dwellings the maximum envelope leakage of 4 ACH50 is permitted provided
the envelope leakage in the Standard Reference Design is 3 ACH50 and all other requirements of
Section R405 are met, including all other mandatory measures. The annual energy cost or source
energy usage of the Proposed Design must be equal to or less than that of the Standard Reference
Design.
2. For multifamily or townhomes and buildings classified as Group R2 and Group R4 of three stories or
less the maximum envelope leakage of less than 5 ACH50 is permitted provided the envelope leakage
in the Standard Reference Design is 3 ACH50 and all other requirements of Section R405 are met,
Amendments to the 2018 International Energy Conservation Code 40
including all other mandatory measures. The annual energy cost or source energy usage of the
Proposed Design must be equal to or less than that of the Standard Reference Design.
(Reason: This ACH tradeoff is approved by ESL and will require additional energy efficiencies to be implemented.
This tradeoff is incorporated in ESL’s IC3 Code Compliance Calculator as the 2015 NCTCOG path in the code
drop down menu. Builders using IC3 will receive a code compliant notification if their designs meet the
requirements of this tradeoff and all other energy code requirements.
Other compliance software products have not incorporated this tradeoff into their compliance reports. Building
Officials receiving Section R405 submittals from software other than IC3 may approve a R405 compliance report
that designates the building as not in compliance due to noncompliance with the 3 ACH50 envelope leakage
mandatory measure, provided the report also states that the envelope leakage is no greater than 4 ACH50 for
single family homes. REScheck™ may+
not have the flexibility to accommodate this tradeoff.)
**Section R405.6.2 (N1105.6.2); add the following sentence to the end of paragraph:
Acceptable performance software simulation tools may include, but are not limited to, REM RateTM; Energy
Gauge®; ICF International Beacon Residential; Ekotrope, HERS Module; Right-Energy HERS and IC3. Other
performance software programs as listed by RESNET® and having the ability to provide a report as outlined in
R405.4.2 may also be deemed acceptable performance simulation programs and may be considered by the
building official.
(Reason: These performance software tools are listed by RESNET at the time of recommendation.)
***Section C405.9. Voltage drop in feeders; deleted in its entirety.
(Reason: There are similar provisions in the NEC where this type of requirement is best managed.)
**TABLE R406.4 (N1106.4) MAXIMUM ENERGY RATING INDEX; amend to read as follows:

Amendments to the 2020 National Electrical Code 42
Amendments to the 2020 National Electrical Code
The following articles, paragraphs, and sentences of the 2020 National Electrical Code (NEC) are
hereby amended as follows: Standard type is text from the NEC. Highlighted with gray shading is text
inserted. Lined through type is deleted text from NEC. A double asterisk (**) at the beginning of an
article identifies an amendment carried over from the 2014 and 2017 edition of the code and a triple
asterisk (***) identifies a new or revised amendment with the 2014 and 2017 code.
**Article 100; add the following to definitions:
Engineering Supervision. Supervision by a Qualified State of Texas Licensed Professional Engineer
engaged primarily in the design or maintenance of electrical installations.
(REASON FOR CHANGE: To better define the qualifications for engineering supervision. This term is
used twenty four times in the 2017 National Electrical Code.)
***Article 100; remove the amendment to the following definition:
Intersystem Bonding Termination. A device that provides a means for connecting intersystem bonding
conductors for communication systems and other systems such as metallic gas piping systems to the
grounding electrode system. Bonding conductors for other systems shall not be larger than 6 AWG.
(REASON FOR CHANGE: Remove the above amendment. Updates to the 2017 National Electrical
Code Article 250.94(A) only accommodate connecting communication systems to an intersystem
bonding termination device, but Article 250.94(B) provides an alternative or other means. To allow for
a termination point for other bonding conductors in addition to communication systems that are
required by the various model codes. 6 AWG was chosen to coincide with the minimum size of
bonding conductor required to the intersystem bonding jumper.)
**Article 110.2; change the following to read as follows:
110.2 Approval. The conductors and equipment required or permitted by this Code shall be
acceptable only if approved. Approval of equipment may be evident by listing and labeling of
equipment by a Nationally Recognized Testing Lab (NRTL) with a certification mark of that laboratory
or a qualified third party inspection agency approved by the AHJ.
Exception: Unlisted equipment that is relocated to another location within a jurisdiction or is field
modified is subject to the approval by the AHJ. This approval may be by a field evaluation by a NRTL
or qualified third party inspection agency approved by the AHJ.
Manufacturer’s self-certification of any equipment shall not be used as a basis for approval by the
AHJ.
Amendments to the 2020 National Electrical Code 43
Informational Note No. 1: See 90.7, Examination of Equipment for Safety, and 110.3, Examination,
Identification, Installation, and Use of Equipment. See definitions of Approved, Identified, Labeled, and
Listed.
Informational Note No. 2: Manufacturer’s self-certification of equipment may not necessarily comply
with U.S. product safety standards as certified by an NRTL.
Informational Note No. 3: National Fire Protection Association (NFPA) 790 and 791 provide an
example of an approved method for qualifying a third party inspection agency.
(REASON FOR CHANGE: To add clarity and provide more positive options for enforcement and
approval of unlisted equipment.)
***Article 210.52(G) (1) Garages: remove the amendment that deleted the following:
(1) Garages. In each attached garage and in each detached garage with electric power. The branch
circuit supplying this receptacle(s) shall not supply outlets outside of the garage. At least one
receptacle outlet shall be installed for each car space.
(REASON FOR CHANGE: Installations in compliance with this Code are not necessarily efficient,
convenient, or adequate for good service or future expansion of electrical use.)
(REASON FOR CHANGE: Updates to this section in the 2017 National Electrical Code provided relief
by removing “shall not supply outlets outside of the garage.”)
***Article 230.71(A); remove the amendment that added the following exception:
Exception: Multi-occupant buildings. Individual service disconnecting means is limited to six for each
occupant. The number of individual disconnects at one location may exceed six.
(REASON FOR CHANGE: This is currently the accepted installation practice of the region. No
noteworthy complaints have surfaced. It is more reasonable than the current NEC requirements. It
allows more than six disconnects grouped at one location. This also allows designers more flexibility
in the placement of electrical meters and main service disconnects.)
(REASON FOR CHANGE: This is below the minimum standard of the 2017 National Electrical Code
adopted by the State of Texas.)
***Article 300.11; remove the amendment that added the following exception:
Exception: Ceiling grid support wires may be used for structural supports when the associated wiring
is located in that area, not more than two raceways or cables supported per wire, with a maximum
nominal metric designation 16 (trade size 1/2”).
(REASON FOR CHANGE: To provide limited support of raceways and cables by ceiling grid support
wire.)
(REASON FOR CHANGE: This is below the minimum standard of the 2017 National Electrical Code
adopted by the State of Texas.)
Amendments to the 2020 National Electrical Code 44
***Article 310.15(B) (7); remove the amendment that changed the following to read as follows:
(7) This Article shall not be used in conjunction with 220.82.
(REASON FOR CHANGE: 310.15(B) (7) has been revised and the table has been deleted.)
(REASON FOR CHANGE: Upon review of the 2014 and 2017 code-making panel 6 and in
conjunction with the wire manufacturing industry, based on the diversification of loads in modern
construction, this amendment becomes irrelevant.)
**Article 500.8 (A) (3); change to read as follows:
500.8 Equipment.
Articles 500 through 504 require equipment construction and installation that ensure safe performance
under conditions of proper use and maintenance.
Informational Note No. 1: It is important that inspection authorities and users exercise more than
ordinary care with regard to installation and maintenance.
Informational Note No. 2: Since there is no consistent relationship between explosion properties and
ignition temperature, the two are independent requirements.
Informational Note No. 3: Low ambient conditions require special consideration. Explosion proof or
dust-ignition proof equipment may not be suitable for use at temperatures lower than -25°C
(-13°F) unless they are identified for low-temperature service. However, at low ambient temperatures,
flammable concentrations of vapors may not exist in a location classified as Class I, Division 1 at
normal ambient temperature.
(A) Suitability. Suitability of identified equipment shall be determined by one of the following:
(1) Equipment listing or labeling;
(2) Evidence of equipment evaluation from a qualified testing laboratory or inspection agency
concerned with product evaluation; or,
(3) Evidence acceptable to the authority having jurisdiction such as a manufacturer's self-
evaluation or an owner's engineering judgment. an engineering judgment signed and sealed
by a qualified Registered licensed Professional Engineer in the State of Texas.
Informational Note: Additional documentation for equipment may include certificates demonstrating
compliance with applicable equipment standards, indicating special conditions of use, and other
pertinent information.
(REASON FOR CHANGE: Carry over from previous amendment with change to better define the
qualifications for an engineering judgment.)
**Article 505.7 (A) changed to read as follows:
Amendments to the 2020 National Electrical Code 45
505.7 Special Precaution.
Article 505 requires equipment construction and installation that ensures safe performance under
conditions of proper use and maintenance.
Informational Note No. 1: It is important that inspection authorities and users exercise more than
ordinary care with regard to the installation and maintenance of electrical equipment in hazardous
(classified) locations.
Informational Note No. 2: Low ambient conditions require special consideration. Electrical equipment
depending on the protection techniques described by 505.8(A) may not be suitable for use at
temperatures lower than -20°C (-4°F) unless they are identified for use at lower temperatures.
However, at low ambient temperatures, flammable concentrations of vapors may not exist in a
location classified Class I, Zones 0, 1, or 2 at normal ambient temperature.
(A) Implementation of Zone Classification System. Classification of areas, engineering and
design, selection of equipment and wiring methods, installation, and inspection shall be
performed by a qualified persons Registered licensed Professional Engineer in the State of
Texas.
(REASON FOR CHANGE: Carry over from previous amendment with change to better define the
qualifications for an engineering judgment.)
***Article 517.30 Essential Electrical Systems for Hospitals; remove the amendment that
created a new (H) and added the following language:
(G) Coordination. Overcurrent protective devices serving the equipment branch of the essential
electrical system shall be coordinated for the period of time that a fault’s duration extends beyond 0.1
second.
Exception No. 1: Between transformer primary and secondary overcurrent protective devices, where
only one overcurrent protective device or set of overcurrent protective
devices exists on the transformer secondary.
Exception No. 2: Between overcurrent protective devices of the same size (ampere rating) in series.
Informational Note: The terms coordination and coordinated as used in this section do not cover the
full range of overcurrent conditions.
(H) Selective Coordination. Overcurrent protective devices serving the life safety, and critical
branches of the essential electrical system shall be selectively coordinated with all supply-side
overcurrent protective devices.
Exception No. 1: Between transformer primary and secondary overcurrent protective devices, where
only one overcurrent protective device or set of overcurrent protective
devices exists on the transformer secondary.
Exception No. 2: Between overcurrent protective devices of the same size (ampere rating) in series.
Amendments to the 2020 National Electrical Code 46
Informational Note: The terms coordination and coordinated as used in this section do not cover the
full range of overcurrent conditions.
(REASON FOR CHANGE: Changes made by deleting the definition of emergency systems in Article
517 Health Care Facilities and removing emergency systems as “Essential Electrical Systems for
Hospitals in 517.30(B) (2), plus the new addition of section 517.30(G) for “Coordination” instead of
using selective coordination, has diminished the reliability of the “Life Safety and Critical Branches of
the Essential Electrical System” to deliver power to vital loads. By providing only “coordination,” the
instantaneous portion of the time-current curve has been eliminated from the overcurrent device
settings.)
(REASON FOR CHANGE: Due to no action by the 2017 code-making panel 15 and NFPA 99, this
amendment is not applicable.)
***Article 600.6(A) (1) At Point of Entry to a Sign; Exception 1 changed to read as follows:
Exception No.1: A disconnect shall not be required for branch circuits(s) or feeder conductor(s)
passing through the sign where enclosed in a Chapter 3 listed raceway or metal-jacketed cable
identified for the location. The conductor(s) shall not serve the sign body or sign enclosure where
passing through.
***Article 600.6(A) (1) At Point of Entry to a Sign; create a new Exception No. 2 to add the
following language:
Exception No. 2. A disconnect shall not be required at the point of entry to a sign body, sign
enclosure, or pole for branch circuit conductor(s). The conductors shall be enclosed in a Chapter 3
listed raceway or metal-jacketed cable identified for the location. The conductor(s) shall be routed to a
device box which contains the disconnect. A field-applied permanent warning label that is visible
during servicing shall be applied to the raceway at or near the point of entry into the sign enclosure or
sign body. The warning label shall comply with 110.21(B) and state the following: “Danger. This
raceway contains energized conductors.” The marking shall include the location of the disconnecting
means for the energized conductor(s). The disconnecting means shall be capable of being locked in
the open position in accordance with 110.25.
***Article 600.6(A) (1) At Point of Entry to a Sign; move the original Exception 2 to create a new
Exception No. 3 and add the following language:
Exception No. 3: A disconnect shall not be required at the point of entry to a sign enclosure or sign
body for branch circuit(s) or feeder conductor(s) that supply an internal panelboard(s) in a sign
enclosure or sign body. The conductors shall be enclosed in a Chapter 3 listed raceway or metal-
jacketed cable identified for the location. A field-applied permanent warning label that is visible during
servicing shall be applied to the raceway at or near the point of entry into the sign enclosure or sign
body. The warning label shall comply with 110.21(B) and state the following: “Danger. This raceway
contains energized conductors.” The marking shall include the location of the disconnecting means for
the energized conductor(s). The disconnecting means shall be capable of being locked in the open
position in accordance with 110.25.
(2017 Code) Informational Note: The location of the disconnect is intended to allow service or
maintenance personnel complete and local control of the disconnecting means.
Amendments to the 2020 National Electrical Code 47
(REASON FOR CHANGE: This is a modification of the nationwide sign manufacturing practice that
was standard before the 2014 Code revision. It is more reasonable but not less than the current Code
requirements. It provides local control of the disconnect by service personnel as the informational note
suggests, while requiring a sign disconnect to be at or within sight of the sign. This also allows sign
designers more flexibility in the placement of the disconnecting means in relation to the location of the
sign.)
***Article 680.25(A) remove the amendment that added the following language and exception:
680.25 Feeders.
These provisions shall apply to any feeder on the supply side of panelboards supplying branch circuits
for pool equipment covered in Part II of this article and on the load side of the service equipment or
the source of a separately derived system.
(A) Wiring Methods.
(1) Feeders. Feeders shall be installed in rigid metal conduit, intermediate metal conduit. The
following wiring methods shall be permitted if not subject to physical damage:
(1) Liquid tight flexible nonmetallic conduit
(2) Rigid polyvinyl chloride conduit
(3) Reinforced thermosetting resin conduit
(4) Electrical metallic tubing where installed on or in a building
(5) Electrical nonmetallic tubing where installed within a building
(6) Type MC Cable where installed within a building and if not subject to corrosive environment
(7) Nonmetallic-sheathed cable

Exception: A feeder within a one-family dwelling or two-family dwelling unit between remote
panelboard and service equipment shall be permitted to run in flexible metal conduit or an approved
cable assembly that includes an insulated equipment grounding conductor within its outer sheath. The
equipment grounding conductor shall comply with 250.24(A) (5).
(REASON FOR CHANGE: Carry over from previous amendments. Text changed to reflect 2014
National Electrical Code. Exception deleted per Errata No.70-14-2)
(REASON FOR CHANGE: Updates to this section in the 2017 National Electrical Code provided relief
by recognizing these wiring methods.)

hand, a minimum of 2/10 pound incrementation and a pressure range not to exceed 20 psi. For welded piping,
and for piping carrying gas at pressures in excess of fourteen (14) inches water column pressure (3.48 kPa) (1/2
psi) and less than 200 inches of water column pressure (52.2 kPa) (7.5 psi), the test pressure shall not be less
than ten (10) pounds per square inch (69.6 kPa). For piping carrying gas at a pressure that exceeds 200 inches
of water column (52.2 kPa) (7.5 psi), the test pressure shall be not less than one and one-half times the proposed
maximum working pressure.
Diaphragm gauges used for testing must display a current calibration and be in good working condition. The
appropriate test must be applied to the diaphragm gauge used for testing.
(Reason: To provide for lesser pressures to coordinate with the use of more accurate diaphragm gauges.)
**Section 409.1; add Section 409.1.4 to read as follows:
409.1.4 Valves in CSST installations. Shutoff valves installed with corrugated stainless steel (CSST) piping
systems shall be supported with an approved termination fitting, or equivalent support, suitable for the size of the
valves, of adequate strength and quality, and located at intervals so as to prevent or damp out excessive vibration
but in no case greater than 12-inches from the center of the valve. Supports shall be installed so as not to interfere
with the free expansion and contraction of the system's piping, fittings, and valves between anchors. All valves
and supports shall be designed and installed so they will not be disengaged by movement of the supporting piping.
Amendments to the 2018 International Fuel Gas Code 58
(Reason: To provide proper security to CSST valves. These standards were established in this region in 1999
when CSST was an emerging technology.)

308.1.4 Open-flame Cooking Devices. Charcoal burners and other oOpen-flame cooking devices, charcoal
grills and other similar devices used for cooking shall not be operated located or used on combustible balconies,
decks, or within 10 feet (3048 mm) of combustible construction.
Exceptions:
1.One- and two-family dwellings, except that LP-gas containers are limited to a water capacity not greater
than 50 pounds (22.68 kg) [nominal 20 pound (9.08 kg) LP-gas capacity] with an aggregate LP-gas
capacity not to exceed 100 pounds (5 containers).
2.Where buildings, balconies and decks are protected by an approved automatic sprinkler system, except
that LP-gas containers are limited to a water capacity not greater than 50 pounds (22.68 kg) [nominal 20
pound (9.08 kg) LP-gas capacity], with an aggregate LP-gas capacity not to exceed 40 lbs. (2
containers).
3.{No change.}
(Reason: Decrease fire risk in multi-family dwellings and minimizes ignition sources and clarify allowable limits
for 1 & 2 family dwellings, and allow an expansion for sprinklered multi-family uses. This amendment adds
clarification and defines the container size allowed for residences.)
**Section 308.1.6.2, Exception #3; change to read as follows:
Amendments to the 2018 International Fire Code 66
Exceptions:
3. Torches or flame-producing devices in accordance with Section 308.4 308.1.3.
(Reason: Section identified in published code is inappropriate.)
**Section 308.1.6.3; change to read as follows:
308.1.6.3 Sky Lanterns. A person shall not release or cause to be released an untethered unmanned free-floating
device containing an open flame or other heat source, such as but not limited to a sky lantern.
(Reason: Eliminates the potential fire hazard presented by utilization of such devices and the potential accidental
release of such devices.)
**Section 311.5; change to read as follows:
311.5 Placards. Any The fire code official is authorized to require marking of any vacant or abandoned buildings
or structures determined to be unsafe pursuant to Section 110 of this code relating to structural or interior hazards,
shall be marked as required by Section 311.5.1 through 311.5.5.
(Reason: There may be situations where placarding is not desired or necessary; also clarifies intent that it is not
the fire code official’s responsibility to provide the placard.)
**Section 403.5; change Section 403.5 to read as follows:
403.5 Group E Occupancies. An approved fire safety and evacuation plan in accordance with Section 404 shall
be prepared and maintained for Group E occupancies and for buildings containing both a Group E occupancy and
an atrium. A diagram depicting two evacuation routes shall be posted in a conspicuous location in each classroom.
Group E occupancies shall also comply with Sections 403.5.1 through 403.5.3.
(Reason: The diagrams are intended to assist with egress in such occupancies – specifically, the primary teacher
is not always present to assist children with egress. Also, such will help reinforce evacuation drill requirements.)
**Section 404.2.2; add Number 4.10 to read as follows:
4.10 Fire extinguishing system controls.
(Reason: The committee believed this information could be of great help to such plans to facilitate locating
sprinkler valves to minimize water damage, for instance.)
**Section 405.4; change Section 405.4 to read as follows:
405.4 Time. The fire code official may require an evacuation drill at any time. Drills shall be held at unexpected
times and under varying conditions to simulate the unusual conditions that occur in case of fire.
(Reason: This change clarifies who may require a fire or evacuation drill).
**Section 501.4; change to read as follows:
501.4 Timing of Installation. When fire apparatus access roads or a water supply for fire protection is required
to be installed for any structure or development, they shall be installed, tested, and approved prior to the time of
which construction has progressed beyond completion of the foundation of any structure. , such protection shall
be installed and made serviceable prior to and during the time of construction except when approved alternative
methods of protection are provided. Temporary street signs shall be installed at each street intersection when
construction of new roadways allows passage by vehicles in accordance with Section 505.2.
Amendments to the 2018 International Fire Code 67
(Reason: Reflects current practice in the region relative to ensuring fire department and EMS access during
construction, which can be a time of increased frequency for emergency incidents.)
**Section 503.1.1; add sentence to read as follows:
Except for one- or two-family dwellings, the path of measurement shall be along a minimum of a ten feet (10’)
wide unobstructed pathway around the external walls of the structure.
(Reason: Recognizes that the hose lay provision can only be measured along a pathway that is wide enough for
fire fighter access.)
**Section 503.2.1; change to read as follows:
503.2.1 Dimensions. Fire apparatus access roads shall have an unobstructed width of not less than 20 24 feet
(6096 mm 7315 mm), exclusive of shoulders, except for approved security gates in accordance with Section
503.6, and an unobstructed vertical clearance of not less than 13 feet 6 inches (4115 mm) 14 feet (4267 mm).
Exception: Vertical clearance may be reduced; provided such reduction does not impair access by fire
apparatus and approved signs are installed and maintained indicating the established vertical clearance when
approved.
(Reason: Amendments to 503.2.1 and 503.2.2 recognize that the equipment now used in firefighting is increasing
in size. The code already recognizes that larger dimensions may be required under Section 503.2.2. The
amendments are to standardize the dimensions for this area. With the increase in fire apparatus size, this will
allow for the passage of two fire apparatus during a fire or EMS emergency.)
**Section 503.2.2; change to read as follows:
503.2.2 Authority. The fire code official shall have the authority to require an increase in the minimum access
widths and vertical clearances where they are inadequate for fire or rescue operations.
(Reason: Amendments to 503.2.1 and 503.2.2 recognize that the equipment now used in firefighting is increasing
in size. The code already recognizes that larger dimensions may be required under Section 503.2.2. The
amendments are to standardize the dimensions for this area. With the increase in fire apparatus size, this will
allow for the passage of two fire apparatus during a fire or EMS emergency.)
**Section 503.2.3; change Section 503.2.3 to read as follows:
503.2.3 Surface. Fire apparatus access roads shall be designed and maintained to support imposed loads of
80,000 Lbs. for fire apparatus and shall be surfaced so as to provide all-weather driving capabilities.
(Reason: To address the current size of fire trucks in use – figure derived from DOT requirements for waiver of
vehicle exceeding such weight.)
**Section 503.3; change to read as follows:
503.3 Marking. Where required by the fire code official, approved signs or other approved notices or markings
that include the words NO PARKING – FIRE LANE Striping, signs, or other markings, when approved by the fire
code official, shall be provided for fire apparatus access roads to identify such roads or prohibit the obstruction
thereof. The means by which fire lanes are designated Striping, signs and other markings shall be maintained in
a clean and legible condition at all times and be replaced or repaired when necessary to provide adequate visibility.
(1) Striping – Fire apparatus access roads shall be continuously marked by painted lines of red traffic paint
six inches (6”) in width to show the boundaries of the lane. The words “NO PARKING FIRE LANE” or "FIRE
LANE NO PARKING” shall appear in four inch (4”) white letters at 25 feet intervals on the red border markings
along both sides of the fire lanes. Where a curb is available, the striping shall be on the vertical face of the
Amendments to the 2018 International Fire Code 68
curb.
(2) Signs – Signs shall read “NO PARKING FIRE LANE” or "FIRE LANE NO PARKING” and shall be 12”
wide and 18” high. Signs shall be painted on a white background with letters and borders in red, using not
less than 2” lettering. Signs shall be permanently affixed to a stationary post and the bottom of the sign shall
be six feet, six inches (6’6”) above finished grade. Signs shall be spaced not more than fifty feet (50’) apart
along both sides of the fire lane. Signs may be installed on permanent buildings or walls or as approved by
the Fire Chief.
(Reason: Establishes a standard method of marking and reflects local long-standing practices.)
**Section 503.4; change to read as follows:
503.4 Obstruction of Fire Apparatus Access Roads. Fire apparatus access roads shall not be obstructed in
any manner, including the parking of vehicles. The minimum widths and clearances established in Section 503.2.1
and any area marked as a fire lane as described in Section 503.3 shall be maintained at all times.
(Reason: As originally worded, the section implied that vehicles could be parked in the marked fire lane and not
be in violation if the minimum width is still maintained. Current accepted enforcement practice is to require the
entire marked fire lane to be maintained clear and unobstructed.)
**Section 505.1; change to read as follows:
**Section 505.1; change to read as follows:
505.1 Address Identification. New and existing buildings shall be provided with approved address identification.
The address identification shall be legible and placed in a position that is visible from the street or road fronting
the property. Address identification characters shall contrast with their background. Address numbers shall be
Arabic numbers or alphabetical letters. Numbers shall not be spelled out. Each character shall be not less than
4 inches (102 mm) 6 inches (152.4 mm) high with a minimum stroke width of 1/2 inch (12.7 mm). Where required
by the fire code official, address numbers shall be provided in additional approved locations to facilitate emergency
response. Where access is by means of a private road, buildings do not immediately front a street, and/or the
building cannot be viewed from the public way, a monument, pole or other sign with approved 6 inch (152.4 mm)
height building numerals or addresses and 4 inch (101.6 mm) height suite/apartment numerals of a color
contrasting with the background of the building or other approved means shall be used to identify the structure.
Numerals or addresses shall be posted on a minimum 20 inch (508 mm) by 30 inch (762 mm) background on
border. Address identification shall be maintained.
Exception: R-3 Single Family occupancies shall have approved numerals of a minimum 3 ½ inches (88.9
mm) in height and a color contrasting with the background clearly visible and legible from the street
fronting the property and rear alleyway where such alleyway exists.
(Reason: To increase the minimum addressing requirements for commercial properties and establish a minimum
for single-family residential properties Such improves legibility of these signs which are critical to emergency
response in a more timely manner.)
**Section 507.4; change to read as follows:
507.4 Water Supply Test Date and Information. The water supply test used for hydraulic calculation of fire
protection systems shall be conducted in accordance with NFPA 291 “Recommended Practice for Fire Flow
Testing and Marking of Hydrants” and within one year of sprinkler plan submittal. The fire code official shall be
notified prior to the water supply test. Water supply tests shall be witnessed by the fire code official, as required
or approved documentation of the test shall be provided to the fire code official prior to final approval of the water
supply system. The exact location of the static/residual hydrant and the flow hydrant shall be indicated on the
design drawings. All fire protection plan submittals shall be accompanied by a hard copy of the waterflow test
report, or as approved by the fire code official. The report must indicate the dominant water tank level at the time
of the test and the maximum and minimum operating levels of the tank, as well, or identify applicable water supply
fluctuation. The licensed contractor must then design the fire protection system based on this fluctuation
information, as per the applicable referenced NFPA standard. Reference Section 903.3.5 for additional design
Amendments to the 2018 International Fire Code 69
requirements.
(Reason: Clarifies intent of the test to ensure contractor accounts for water supply fluctuations.)
**Section 507.5.4; change to read as follows:
507.5.4 Obstruction. Unobstructed access to fire hydrants shall be maintained at all times. Posts, fences,
vehicles, growth, trash, storage and other materials or objects shall not be placed or kept near fire hydrants, fire
department inlet connections or fire protection system control valves in a manner that would prevent such
equipment or fire hydrants from being immediately discernible. The fire department shall not be deterred or
hindered from gaining immediate access to fire protection equipment or fire hydrants.
(Reason: Additional guidance based on legacy language to ensure these critical devices are available in an
emergency incident.)
**Section 509.1.2; add new Section 509.1.2 to read as follows:
509.1.2 Sign Requirements. Unless more stringent requirements apply, lettering for signs required by this
section shall have a minimum height of 2 inches (50.8 mm) when located inside a building and 4 inches (101.6
mm) when located outside, or as approved by the fire code official. The letters shall be of a color that contrasts
with the background.
(Reason: Provides direction as to appropriate sign criteria to develop local and regional
consistency in this regard.)
***Section 603.3.2 and 603.3.2.1; change to read as follows:
603.3.1 Fuel oil storage in outside, above-ground tanks. Where connected to a fuel-oil piping system, the
maximum amount of fuel oil storage allowed outside above ground without additional protection shall be 660
gallons (2498 L). The storage of fuel oil above ground in quantities exceeding 660 gallons (2498 L) shall comply
with NFPA 31 and Chapter 57.
603.3.2 Fuel oil storage inside buildings. Fuel oil storage inside buildings shall comply with Sections 603.3.2.1
through 603.3.2.5 or and Chapter 57.
603.3.2.1 Quantity limits. One or more fuel oil storage tanks containing Class II or III combustible liquid shall be
permitted in a building. The aggregate capacity of all tanks shall not exceed the following:
1. 660 gallons (2498 L) in unsprinklered buildings, where stored in a tank complying with UL 80, UL 142 or
UL 2085 for Class III liquids, and also listed as a double-wall/secondary containment tank for Class II
liquids.
2. 1,320 gallons (4996 L) in buildings equipped with an automatic sprinkler system in accordance with
Section 903.3.1.1, where stored in a tank complying with UL 142 or UL 2085 as a double-wall/secondary
containment tank.
3. 3,000 gallons (11 356 L) where stored in protected above-ground tanks complying with UL 2085 and
Section 5704.2.9.7 and the room is protected by an automatic sprinkler system in accordance with Section
903.3.1.1.
(Reason: Issues addressed by Chapter 57, such as venting to outside of buildings, remote fill to outside of building,
overfill protection, physical protection, etc., are not included in Section 603.3, so compliance with Chapter 57 is
also required. The Board determined that fuel storage in such tanks inside of buildings is commonly in double-
wall tanks, and that this inherent leak protection was prudent in order to allow these quantities of combustible
liquids to be stored inside a building for such purpose.)
**Section 807.5.2.2 and 807.5.2.3; change to read as follows:
807.5.2.2 Artwork in Corridors. Artwork and teaching materials shall be limited on the walls of corridors to not
more than 20 percent of the wall area. Such materials shall not be continuous from floor to ceiling or wall to wall.
Amendments to the 2018 International Fire Code 70
Curtains, draperies, wall hangings, and other decorative material suspended from the walls or ceilings shall meet
the flame propagation performance criteria of NFPA 701 in accordance with Section 807 or be noncombustible.
Exception: Corridors protected by an approved automatic sprinkler system installed in accordance with
Section 903.3.1.1 shall be limited to 50 percent of the wall area.
807.5.2.3 Artwork in Classrooms. Artwork and teaching materials shall be limited on walls of classrooms to not
more than 50 percent of the specific wall area to which they are attached.
Curtains, draperies, wall hangings and other decorative material suspended from the walls or ceilings shall meet
the flame propagation performance criteria of NFPA 701 in accordance with Section 807 or be noncombustible.
(Reason: This change allows an increase in wall coverage due to the presence of sprinklers. Also provides
additional guidance relative to fire resistance requirements in these areas.)
**Section 807.5.5.2 and 807.5.5.3; change to read as follows:
807.5.5.2 Artwork in Corridors. Artwork and teaching materials shall be limited on the walls of corridors to not
more than 20 percent of the wall area. Such materials shall not be continuous from floor to ceiling or wall to wall.
Curtains, draperies, wall hangings and other decorative material suspended from the walls or ceilings shall meet
the flame propagation performance criteria of NFPA 701 in accordance with Section 807 or be noncombustible.
Exception: Corridors protected by an approved automatic sprinkler system installed in accordance with
Section 903.3.1.1 shall be limited to 50 percent of the wall area.
807.5.5.3 Artwork in Classrooms. Artwork and teaching materials shall be limited on walls of classrooms to not
more than 50 percent of the specific wall area to which they are attached. Curtains, draperies, wall hangings and
other decorative material suspended from the walls or ceilings shall meet the flame propagation performance
criteria of NFPA 701 in accordance with Section 807 or be noncombustible.
(Reason: This change allows an increase in wall coverage due to the presence of sprinklers. Also provides
additional guidance relative to fire resistance requirements in these areas.)
***Section 901.6.1; add Section 901.6.1.1 to read as follows:
901.6.1.1 Standpipe Testing. Building owners/managers must maintain and test standpipe systems as per NFPA
25 requirements. The following additional requirements shall be applied to the testing that is required every 5
years:
10. The piping between the Fire Department Connection (FDC) and the standpipe shall be backflushed or
inspected by approved camera when foreign material is present or when caps are missing, and also
hydrostatically tested for all FDC’s on any type of standpipe system. Hydrostatic testing shall also be
conducted in accordance with NFPA 25 requirements for the different types of standpipe systems.
11. For any manual (dry or wet) standpipe system not having an automatic water supply capable of flowing
water through the standpipe, the tester shall connect hose from a fire hydrant or portable pumping system
(as approved by the fire code official) to each FDC, and flow water through the standpipe system to the roof
outlet to verify that each inlet connection functions properly. Confirm that there are no open hose valves
prior to introducing water into a dry standpipe. There is no required pressure criteria at the outlet. Verify that
check valves function properly and that there are no closed control valves on the system.
12. Any pressure relief, reducing, or control valves shall be tested in accordance with the requirements of NFPA
25. All hose valves shall be exercised.
13. If the FDC is not already provided with approved caps, the contractor shall install such caps for all FDC’s
as required by the fire code official.
14. Upon successful completion of standpipe test, place a blue tag (as per Texas Administrative Code, Fire
Sprinkler Rules for Inspection, Test and Maintenance Service (ITM) Tag) at the bottom of each standpipe
riser in the building. The tag shall be check-marked as “Fifth Year” for Type of ITM, and the note on the
back of the tag shall read “5 Year Standpipe Test” at a minimum.
Amendments to the 2018 International Fire Code 71
15. The procedures required by Texas Administrative Code Fire Sprinkler Rules with regard to Yellow Tags
and Red Tags or any deficiencies noted during the testing, including the required notification of the local
Authority Having Jurisdiction (fire code official) shall be followed.
16. Additionally, records of the testing shall be maintained by the owner and contractor, if applicable, as
required by the State Rules mentioned above and NFPA 25.
17. Standpipe system tests where water will be flowed external to the building shall not be conducted during
freezing conditions or during the day prior to expected night time freezing conditions.
18. Contact the fire code official for requests to remove existing fire hose from Class II and III standpipe systems
where employees are not trained in the utilization of this firefighting equipment. All standpipe hose valves
must remain in place and be provided with an approved cap and chain when approval is given to remove
hose by the fire code official.
(Reason: Increases the reliability of the fire protection system and re-emphasizes the requirements of NFPA 25
relative to standpipe systems, as well as ensuring that FDC connections are similarly tested/maintained to ensure
operation in an emergency incident.)
**Section 901.6.4; add Section 901.6.4 to read as follows:
901.6.4 False Alarms and Nuisance Alarms. False alarms and nuisance alarms shall not be given, signaled or
transmitted or caused or permitted to be given, signaled or transmitted in any manner.
(Reason: Places the responsibility on the business or property owner to maintain their fire alarm systems in
approved condition. Allows the enforcement of “prohibition of false alarms”. Replaces text lost from the legacy
codes that helps to ensure the maintenance of life safety systems.)
**Section 901.7; change to read as follows:
901.7 Systems Out of Service. Where a required fire protection system is out of service or in the event of an
excessive number of activations, the fire department and the fire code official shall be notified immediately and,
where required by the fire code official, the building shall either be evacuated or an approved fire watch shall be
provided for all occupants left unprotected by the shut down until the fire protection system has been returned to
service. … {Remaining text unchanged}
(Reason: Gives fire code official more discretion with regards to enforcement of facilities experiencing nuisance
alarm or fire protection system activations necessitating correction/repair/replacement. The intent of the
amendment is to allow local jurisdictions to enforce fire watches, etc., where needed to ensure safety of occupants
where fire protection systems are experiencing multiple nuisance activations.)
**Section 903.1.1; change to read as follows:
903.1.1 Alternative Protection. Alternative automatic fire-extinguishing systems complying with Section 904 shall
be permitted instead of in addition to automatic sprinkler protection where recognized by the applicable standard
and, or as approved by the fire code official.
(Reason: Such alternative systems do not provide the reliability of automatic sprinkler protection. Most gaseous
type systems are highly susceptible to open doors, ceiling or floor tile removal, etc. However, an applicant could
pursue an Alternate Method request to help mitigate the reliability issues with these alternative systems with the
fire code official if so desired, or there may be circumstances in which the fire code official is acceptable to allowing
an alternate system in lieu of sprinklers, such as kitchen hoods or paint booths.)
**Section 903.2.8; add sentence to read as follows:
903.2.8 Group R. An automatic sprinkler system installed in accordance with Section 903.3 shall be provided
Amendments to the 2018 International Fire Code 72
throughout all buildings with a Group R fire area except as amended for Group R-3 occupancies.
(Reason: Amendment carried forward from previous codes)
**Section 903.2.8.1; add sentence to read as follows:
903.2.8.1 Group R-3. R903.2.10.7 An automatic sprinkler system installed in accordance with Section 903.3 shall
be provided throughout all buildings with a Group R fire area except as amended for Group R-3 occupancies.
R903.2.10.7 An automatic sprinkler system shall be installed in all Group R-3 buildings with a building area over
7,500 square feet or living area over 6,000 square feet. For the purpose of this provision, living area shall include
all areas included in “air conditioned”, future or “bonus rooms” or other areas determined to be actual or intended
living areas.
(Reason: Amendment carried forward from previous codes)
**Section 903.2; add paragraph to read as follows and delete the exception:
Automatic Sprinklers shall not be installed in elevator machine rooms, elevator machine spaces, and elevator
hoistways, other than pits where such sprinklers would not necessitate shunt trip requirements under any
circumstances. Storage shall not be allowed within the elevator machine room. Signage shall be provided at the
entry doors to the elevator machine room indicating “ELEVATOR MACHINERY – NO STORAGE ALLOWED.”
(Reason: Firefighter and public safety. This amendment eliminates the shunt trip requirement of the International
Building Code Section 3005.5 for the purpose of elevator passenger and firefighter safety. This amendment is
contingent on the Building Code amendment eliminating the Exceptions to Section 3005.4, such that passive fire
barriers for these areas are maintained. The exception deletion is due to the fact that such telecom areas pose
an undue fire risk to the structural integrity of the building.)
**Section 903.2.9; add Section 903.2.9.3 to read as follows:
903.2.9.3 Self-Service Storage Facility. An automatic sprinkler system shall be installed throughout all self-
service storage facilities.
(Reason: Fire departments are unable to inspect these commercial occupancies and are unaware of the contents
being stored. Previous allowance to separate units by fire barriers is difficult to enforce maintenance after
opening.)
Section 903.2.11; change 903.2.11.3 and add 903.2.11.7, 903.2.11.8, and 903.2.11.9 as follows:
903.2.11.3 Buildings 55 35 feet or more in height. An automatic sprinkler system shall be installed
throughout buildings that have one or more stories with an occupant load of 30 or more, other than penthouses
in compliance with Section 1510 of the International Building Code, located 55 35 feet (16 764 10 668 mm)
or more above the lowest level of fire department vehicle access, measured to the finished floor.
Exceptions:
1.Open parking structures in compliance with Section 406.5 of the International Building Code,
having no other occupancies above the subject garage.
2. Occupancies in Group F-2.
903.2.11.7 High-Piled Combustible Storage. For any building with a clear height exceeding 12 feet (4572
mm), see Chapter 32 to determine if those provisions apply.
903.2.11.8 Spray Booths and Rooms. New and existing spray booths and spraying rooms shall be protected
by an approved automatic fire-extinguishing system.
Amendments to the 2018 International Fire Code 73
903.2.11.9 Buildings Over 6,000 sq. ft. An automatic sprinkler system shall be installed throughout all
buildings with a building area 6,000 sq. ft. or greater and in all existing buildings that are enlarged to be 6,000
sq. ft. or greater. For the purpose of this provision, fire walls shall not define separate buildings.
Exception: Open parking garages in compliance with Section 406.5 of the International Building Code.
(Reason: Provides jurisdictions options as to their desired level of sprinkler protection based on multiple factors
including firefighting philosophies/capabilities.)
**Section 903.3.1.1.1; change to read as follows:
903.3.1.1.1 Exempt Locations. When approved by the fire code official, automatic sprinklers shall not be
required in the following rooms or areas where such ... {text unchanged}… because it is damp, of fire-resistance-
rated construction or contains electrical equipment.
7.Any room where the application of water, or flame and water, constitutes a serious life or fire hazard.
8.Any room or space where sprinklers are considered undesirable because of the nature of the contents,
when approved by the code official.
9.Generator and transformer rooms, under the direct control of a public utility, separated from the remainder
of the building by walls and floor/ceiling or roof/ceiling assemblies having a fire-resistance rating of not
less than 2 hours.
10.In rooms or areas that are of noncombustible construction with wholly noncombustible contents.
11.Fire service access Elevator machine rooms, and machinery spaces, and hoistways, other than pits where
such sprinklers would not necessitate shunt trip requirements under any circumstances.
12.{Delete.}
(Reason: Gives more direction to code official. Exception 4 deleted to provide protection where fire risks are poorly
addressed. Amendment 903.2 addresses Exception 5 above relative to the elimination of sprinkler protection in
these areas to avoid the shunt trip requirement.)
***Section 903.3.1.2.3; delete section and replace as follows:
[F] Section 903.3.1.2.3 Attached Garages and Attics. Sprinkler protection is required in attached garages, and
in the following attic spaces:
1.Attics that are used or intended for living purposes or storage shall be protected by an automatic
sprinkler system.
2.Where fuel-fired equipment is installed in an unsprinklered attic, not fewer than one quick-response
intermediate temperature sprinkler shall be installed above the equipment.
3.Attic spaces of buildings that are two or more stories in height above grade plane or above the lowest
level of fire department vehicle access.
4.Group R-4, Condition 2 occupancy attics not required by Item 1 or 3 to have sprinklers shall comply
with one of the following:
4.1. Provide automatic sprinkler system protection.
4.2. Provide a heat detection system throughout the attic that is arranged to activate the building
fire alarm system.
4.3. Construct the attic using noncombustible materials.
4.4. Construct the attic using fire-retardant-treated wood complying with Section 2303.2 of the
International Building Code.
4.5. Fill the attic with noncombustible insulation.
(Reason: Attic protection is required due to issues with fire exposure via soffit vents, as well as firefighter safety.
Several jurisdictions indicated experience with un-protected attic fires resulting in displacement of all building
occupants. NFPA 13 provides for applicable attic sprinkler protection requirements, as well as exemptions to such,
based on noncombustible construction, etc. Attached garages already require sprinklers via NFPA 13R – this
amendment just re-emphasizes the requirement.)
Amendments to the 2018 International Fire Code 74
**Section 903.3.1.3; change to read as follows:
903.3.1.3 NFPA 13D Sprinkler Systems. Automatic sprinkler systems installed in one- and two-family dwellings;
Group R-3; Group R-4, Condition 1; and townhouses shall be permitted to be installed throughout in accordance
with NFPA 13D or in accordance with state law.
(Reason: To allow the use of the Plumbing section of the International Residential Code (IRC) and recognize
current state stipulations in this regard.)
**Section 903.3.1.4; add to read as follows:
[F] 903.3.1.4 Freeze protection. Freeze protection systems for automatic fire sprinkler systems shall be in
accordance with the requirements of the applicable referenced NFPA standard and this section.
903.3.1.4.1 Attics. Only dry-pipe, pre-action, or listed antifreeze automatic fire sprinkler systems shall be
allowed to protect attic spaces.
Exception: Wet-pipe fire sprinkler systems shall be allowed to protect non-ventilated attic spaces
where:
4. The attic sprinklers are supplied by a separate floor control valve assembly to allow ease
of draining the attic system without impairing sprinklers throughout the rest of the building,
and
5. Adequate heat shall be provided for freeze protection as per the applicable referenced
NFPA standard, and
6. The attic space is a part of the building’s thermal, or heat, envelope, such that insulation
is provided at the roof deck, rather than at the ceiling level.
903.3.1.4.2 Heat trace/insulation. Heat trace/insulation shall only be allowed where approved by the fire
code official for small sections of large diameter water-filled pipe.
(Reason: In the last few years, severe winters brought to light several issues with current practices for sprinklering
attics, not the least of which was wet-pipe sprinklers in ventilated attics provided with space heaters, etc. for freeze
protection of such piping. This practice is not acceptable for the protection of water-filled piping in a ventilated
attic space as it does not provide a reliable means of maintaining the minimum 40 degrees required by NFPA,
wastes energy, and presents a potential ignition source to the attic space. Listed antifreeze is specifically included
because NFPA currently allows such even though there is no currently listed antifreeze at the time of development
of these amendments. The intent of this amendment is to help reduce the large number of freeze breaks that
have occurred in the past with water-filled wet-pipe sprinkler systems in the future, most specifically in attic
spaces.)
**Section 903.3.5; add a second paragraph to read as follows:
Water supply as required for such systems shall be provided in conformance with the supply requirements of the
respective standards; however, every water-based fire protection system shall be designed with a 10 psi safety
factor. Reference Section 507.4 for additional design requirements.
(Reason: To define uniform safety factor for the region.)
**Section 903.4; add a second paragraph after the exceptions to read as follows:
Sprinkler and standpipe system water-flow detectors shall be provided for each floor tap to the sprinkler system
and shall cause an alarm upon detection of water flow for more than 45 seconds. All control valves in the sprinkler
and standpipe systems except for fire department hose connection valves shall be electrically supervised to initiate
a supervisory signal at the central station upon tampering.
(Reason: To avoid significant water losses. Consistent with amendment to IFC 905.9.)
Amendments to the 2018 International Fire Code 75
**Section 903.4.2; add second paragraph to read as follows:
The alarm device required on the exterior of the building shall be a weatherproof horn/strobe notification appliance
with a minimum 75 candela strobe rating, installed as close as practicable to the fire department connection.
(Reason: Fire department connections are not always located at the riser; this allows the fire department faster
access.)
**Section 905.2; change to read as follows:
905.2 Installation Standard. Standpipe systems shall be installed in accordance with this section and NFPA 14.
Manual dry standpipe systems shall be supervised with a minimum of 10 psig and a maximum of 40 psig air
pressure with a high/low alarm.
(Reason: To define manual dry standpipe supervision requirements. Helps ensure the integrity of the standpipe
system via supervision, such that open hose valves will result in a supervisory low air alarm.)
***Section 905.3; add Section 905.3.9 and exception to read as follows:
905.3.9 Buildings Exceeding 10,000 sq. ft. In buildings exceeding 10,000 square feet in area per story and
where any portion of the building’s interior area is more than 200 feet (60960 mm) of travel, vertically and
horizontally, from the nearest point of fire department vehicle access, Class I automatic wet or manual wet
standpipes shall be provided.
Exceptions:
3. Automatic dry, semi-automatic dry, and manual dry standpipes are allowed as provided for in NFPA
14 where approved by the fire code official.
4. R-2 occupancies of four stories or less in height having no interior corridors.
(Reason: Allows for the rapid deployment of hose lines to the body of the fire. Manual dry option added this
edition.)
**Section 905.4, change Item 1, 3, and 5, and add Item 7 to read as follows:
1. In every required interior exit stairway, a hose connection shall be provided for each story above and below
grade plane. Hose connections shall be located at an intermediate landing between stories, unless
otherwise approved by the fire code official.
2. {No change.}
3. In every exit passageway, at the entrance from the exit passageway to other areas of a building.
Exception: Where floor areas adjacent to an exit passageway are reachable from an interior exit stairway
hose connection by a {remainder of text unchanged}
4. {No change.}
5. Where the roof has a slope less than four units vertical in 12 units horizontal (33.3-percent slope), each
standpipe shall be provided with a two-way a hose connection shall be located to serve the roof or at the
highest landing of an interior exit stairway with stair access to the roof provided in accordance with Section
1011.12.
6. {No change.}
7. When required by this Chapter, standpipe connections shall be placed adjacent to all required exits to the
structure and at two hundred feet (200’) intervals along major corridors thereafter, or as otherwise approved
by the fire code official.
(Reason: Item 1, 3, and 5 amendments to remove ‘interior’ will help to clarify that such connections are required
for all ‘exit’ stairways, to ensure firefighter capabilities are not diminished in these tall buildings, simply because
Amendments to the 2018 International Fire Code 76
the stair is on the exterior of the building. Item 5 reduces the amount of pressure required to facilitate testing, and
provides backup protection for fire fighter safety. Item 7 allows for the rapid deployment of hose lines to the body
of the fire.)
**Section 905.9; add a second paragraph after the exceptions to read as follows:
Sprinkler and standpipe system water-flow detectors shall be provided for each floor tap to the sprinkler system
and shall cause an alarm upon detection of water flow for more than 45 seconds. All control valves in the sprinkler
and standpipe systems except for fire department hose connection valves shall be electrically supervised to initiate
a supervisory signal at the central station upon tampering.
(Reason: To avoid significant water losses. Consistent with amendment to IFC 903.4.)
**Section 907.1; add Section 907.1.4 and 907.1.4.1 to read as follows:
907.1.4 Design Standards. Where a new fire alarm system is installed, the devices shall be addressable. Fire
alarm systems utilizing more than 20 smoke detectors shall have analog initiating devices.
(Reason: Provides for the ability of descriptive identification of alarms, and reduces need for panel replacement
in the future. Updated wording to match the language of the new requirement at 907.5.2.3. Change of terminology
allows for reference back to definitions of NFPA 72.)
**Section 907.2.1; change to read as follows:
907.2.1 Group A. A manual fire alarm system that activates the occupant notification system in accordance with
Section 907.5 shall be installed in Group A occupancies where the having an occupant load due to the assembly
occupancy is of 300 or more persons, or where the Group A occupant load is more than 100 persons above or
below the lowest level of exit discharge. Group A occupancies not separated from one another in accordance with
Section 707.3. 10 of the International Building Code shall be considered as a single occupancy for the purposes
of applying this section. Portions of Group E occupancies occupied for assembly purposes shall be provided with
a fire alarm system as required for the Group E occupancy.
Exception: {No change.}
Activation of fire alarm notification appliances shall:
1. Cause illumination of the means of egress with light of not less than 1 foot-candle (11 lux) at the walking
surface level, and
2. Stop any conflicting or confusing sounds and visual distractions.
(Reason: Increases the requirement to be consistent with Group B requirement. Also addresses issue found in
Group A occupancies of reduced lighting levels and other A/V equipment that distracts from fire alarm notification
devices or reduces ability of fire alarm system to notify occupants of the emergency condition.)
**Section 907.2.3; change to read as follows:
907.2.3 Group E. A manual fire alarm system that initiates the occupant notification signal utilizing an emergency
voice/alarm communication system meeting the requirements of Section 907.5.2.2 and installed in accordance
with Section 907.6 shall be installed in Group E educational occupancies. When automatic sprinkler systems or
smoke detectors are installed, such systems or detectors shall be connected to the building fire alarm system. An
approved smoke detection system shall be installed in Group E day care occupancies. Unless separated by a
minimum of 100' open space, all buildings, whether portable buildings or the main building, will be considered one
building for alarm occupant load consideration and interconnection of alarm systems.
Exceptions:
2. {No change.}
Amendments to the 2018 International Fire Code 77
1.2. Residential In-Home day care with not more than 12 children may use interconnected single
station detectors in all habitable rooms. (For care of more than five children 2 1/2 or less years of
age, see Section 907.2.6.) {No change to remainder of exceptions.}
(Reason: To distinguish educational from day care occupancy minimum protection requirements. Further, to
define threshold at which portable buildings are considered a separate building for the purposes of alarm systems.
Exceptions provide consistency with State law concerning such occupancies.)
**Section 907.2.12, Exception 3; change to read as follows:
3.Open air portions of buildings with an occupancy in Group A-5 in accordance with Section 303.1 of the
International Building Code; however, this exception does not apply to accessory uses including but not limited
to sky boxes, restaurants, and similarly enclosed areas.
(Reason: To indicate that enclosed areas within open air seating type occupancies are not exempted from
automatic fire alarm system requirements.)
**Section 907.4.2; add Section 907.4.2.7 to read as follows:
907.4.2.7 Type. Manual alarm initiating devices shall be an approved double action type.
(Reason: Helps to reduce false alarms.)
**Section 907.6.1; add Section 907.6.1.1 to read as follows:
907.6.1.1 Wiring Installation. All fire alarm systems shall be installed in such a manner that a failure of any
single initiating device or single open in an initiating circuit conductor will not interfere with the normal operation
of other such devices. All signaling line circuits (SLC) shall be installed in such a way that a single open will not
interfere with the operation of any addressable devices (Class A). Outgoing and return SLC conductors shall be
installed in accordance with NFPA 72 requirements for Class A circuits and shall have a minimum of four feet
separation horizontal and one foot vertical between supply and return circuit conductors. The initiating device
circuit (IDC) from a signaling line circuit interface device may be wired Class B, provided the distance from the
interface device to the initiating device is ten feet or less.
(Reason: To provide uniformity in system specifications and guidance to design engineers. Improves reliability of
fire alarm devices and systems.)
**Section 907.6.3; delete all four Exceptions.
(Reason: To assist responding personnel in locating the emergency event for all fire alarm systems. This is moved
from 907.6.5.3 in the 2012 IFC and reworded to match new code language and sections.)
**Section 907.6.6; – add sentence at end of paragraph to read as follows:
See 907.6.3 for the required information transmitted to the supervising station.
(Reason: To assist responding personnel in locating the emergency event for all fire alarm systems. This is
moved from 907.6.5.3 in the 2012 IFC and reworded to match new code language and sections.)
**Section 909.22; add to read as follows:
909.22 Stairway or Ramp Pressurization Alternative. Where the building is equipped throughout with an
automatic sprinkler system in accordance with Section 903.3.1.1 and the stair pressurization alternative is chosen
for compliance with Building Code requirements for a smokeproof enclosure, interior exit stairways or ramps shall
be pressurized to a minimum of 0.10 inches of water (25 Pa) and a maximum of 0.35 inches of water (87 Pa) in
the shaft relative to the building measured with all interior exit stairway and ramp doors closed under maximum
Amendments to the 2018 International Fire Code 78
anticipated conditions of stack effect and wind effect. Such systems shall comply with Section 909, including the
installation of a separate fire-fighter’s smoke control panel as per Section 909.16, and a Smoke Control Permit
shall be required from the fire department as per Section 105.7.
909.22.1 Ventilating equipment. The activation of ventilating equipment for the stair or ramp pressurization
system shall be by smoke detectors installed at each floor level at an approved location at the entrance to the
smokeproof enclosure. When the closing device for the stairway or ramp shaft and vestibule doors is activated by
smoke detection or power failure, the mechanical equipment shall activate and operate at the required
performance levels. Smoke detectors shall be installed in accordance with Section 907.3.
909.22.1.1 Ventilation Systems. Smokeproof enclosure ventilation systems shall be independent of other
building ventilation systems. The equipment, control wiring, power wiring and ductwork shall comply with one of
the following:
1. Equipment, control wiring, power wiring and ductwork shall be located exterior to the building and
directly connected to the smokeproof enclosure or connected to the smokeproof enclosure by ductwork
enclosed by not less than 2-hour fire barriers constructed in accordance with Section 707 of the
Building Code or horizontal assemblies constructed in accordance with Section 711 of the Building
Code, or both.
2. Equipment, control wiring, power wiring and ductwork shall be located within the smokeproof enclosure
with intake or exhaust directly from and to the outside or through ductwork enclosed by not less than
2-hour barriers constructed in accordance with Section 707 of the Building Code or horizontal
assemblies constructed in accordance with Section 711 of the Building Code, or both.
3. Equipment, control wiring, power wiring and ductwork shall be located within the building if separated
from the remainder of the building, including other mechanical equipment, by not less than 2-hour fire
barriers constructed in accordance with Section 707 of the Building Code or horizontal assemblies
constructed in accordance with Section 711 of the Building Code, or both.
Exceptions:
1. Control wiring and power wiring utilizing a 2-hour rated cable or cable system.
2. Where encased with not less than 2 inches (51 mm) of concrete.
3. Control wiring and power wiring protected by a listed electrical circuit protective systems with a fire-
resistance rating of not less than 2 hours.
909.21.1.2 Standby Power. Mechanical vestibule and stairway and ramp shaft ventilation systems and automatic
fire detection systems shall be provided with standby power in accordance with Section 2702 of the Building Code.
909.22.1.3 Acceptance and Testing. Before the mechanical equipment is approved, the system shall be tested
in the presence of the fire code official to confirm that the system is operating in compliance with these
requirements.
(Reason: To assist with enforcement of such as a smoke control system, as per Section 909.6.3, especially since
a permit is now specifically required for such systems in the Fire Code. Also ensures that a firefighter’s override
panel is provided as per 909.16 for such systems. The above amendment copies the applicable requirements for
such systems from Section 909.20 of the Building Code into the Fire Code. Although the published code did copy
the elevator pressurization requirements into the Fire Code, it did not copy over the stair pressurization
requirements.)
**Section 910.2; change Exception 2. and 3.to read as follows:
2.Only manual smoke and heat removal shall not be required in areas of buildings equipped with early
suppression fast-response (ESFR) sprinklers. Automatic smoke and heat removal is prohibited.
3.Only manual smoke and heat removal shall not be required in areas of buildings equipped with control
mode special application sprinklers with a response time index of 50(m*S)1/2 or less that are listed to
control a fire in stored commodities with 12 or fewer sprinklers. Automatic smoke and heat removal is
prohibited.
Amendments to the 2018 International Fire Code 79
(Reason: Allows the fire department to control the smoke and heat during and after a fire event, while still
prohibiting such systems from being automatically activated, which is a potential detriment to the particular
sprinkler systems indicated.)
**Section 910.2; add subsections 910.2.3 with exceptions to read as follows:
910.2.3 Group H. Buildings and portions thereof used as a Group H occupancy as follows:
1. In occupancies classified as Group H-2 or H-3, any of which are more than 15,000 square feet (1394 m2)
in single floor area.
Exception: Buildings of noncombustible construction containing only noncombustible materials.
2. In areas of buildings in Group H used for storing Class 2, 3, and 4 liquid and solid oxidizers, Class 1 and
unclassified detonable organic peroxides, Class 3 and 4 unstable (reactive) materials, or Class 2 or 3
water-reactive materials as required for a high-hazard commodity classification.
Exception: Buildings of noncombustible construction containing only noncombustible materials.
(Reason: Maintains a fire protection device utilized in such occupancies where it is sometimes necessary to allow
chemicals to burn out, rather than extinguish.)
**Section 910.3; add section 910.3.4 to read as follows:
910.3.4 Vent Operation. Smoke and heat vents shall be capable of being operated by approved automatic and
manual means. Automatic operation of smoke and heat vents shall conform to the provisions of Sections 910.3.2.1
through 910.3.2.3.
910.3.4.1 Sprinklered buildings. Where installed in buildings equipped with an approved automatic sprinkler
system, smoke and heat vents shall be designed to operate automatically.
The automatic operating mechanism of the smoke and heat vents shall operate at a temperature rating at least
100 degrees F (approximately 38 degrees Celsius) greater than the temperature rating of the sprinklers installed.
Exception: Manual only systems per Section 910.2.
910.3.4.2 Nonsprinklered Buildings. Where installed in buildings not equipped with an approved automatic
sprinkler system, smoke and heat vents shall operate automatically by actuation of a heat-responsive device rated
at between 100°F (56°C) and 220°F (122°C) above ambient.
Exception: Listed gravity-operated drop out vents.
(Reason: Amendment continues to keep applicable wording from prior to the 2012 edition of the IFC. Specifically,
automatic activation criteria is no longer specifically required in the published code. Specifying a temperature
range at which smoke and heat vents should activate in sprinklered buildings helps to ensure that the sprinkler
system has an opportunity to activate and control the fire prior to vent operation.)
**Section 910.4.3.1; change to read as follows:
910.4.3.1 Makeup Air. Makeup air openings shall be provided within 6 feet (1829 mm) of the floor level. Operation
of makeup air openings shall be manual or automatic. The minimum gross area of makeup air inlets shall be 8
square feet per 1,000 cubic feet per minute (0.74 m2 per 0.4719 m3/s) of smoke exhaust.
(Reason: Makeup air has been required to be automatic for several years now in this region when mechanical
smoke exhaust systems are proposed. This allows such systems to be activated from the smoke control panel
by first responders without having to physically go around the exterior of the building opening doors manually.
Amendments to the 2018 International Fire Code 80
Such requires a significant number of first responders on scene to conduct this operation and significantly delays
activation and/or capability of the smoke exhaust system.)
**Section 912.2; add Section 912.2.3 to read as follows:
912.2.3 Hydrant Distance. An approved fire hydrant shall be located within 100 feet of the fire department
connection as the fire hose lays along an unobstructed path.
(Reason: To accommodate limited hose lengths, improve response times where the FDC is needed to achieve
fire control, and improve ease of locating a fire hydrant in those situations also. Also, consistent with NFPA 14
criteria.)
**Section 913.2.1; add second paragraph and exception to read as follows:
When located on the ground level at an exterior wall, the fire pump room shall be provided with an exterior fire
department access door that is not less than 3 ft. in width and 6 ft. – 8 in. in height, regardless of any interior doors
that are provided. A key box shall be provided at this door, as required by Section 506.1.
Exception: When it is necessary to locate the fire pump room on other levels or not at an exterior wall, the
corridor leading to the fire pump room access from the exterior of the building shall be provided with equivalent
fire resistance as that required for the pump room, or as approved by the fire code official. Access keys shall
be provided in the key box as required by Section 506.1.
(Reason: This requirement allows fire fighters safer access to the fire pump room. The requirement allows access
without being required to enter the building and locate the fire pump room interior access door during a fire event.
The exception recognizes that this will not always be a feasible design scenario for some buildings, and as such,
provides an acceptable alternative to protect the pathway to the fire pump room.)
**Section 914.3.1.2; change to read as follows:
914.3.1.2 Water Supply to required Fire Pumps. In buildings that are more than 420 120 feet (37 m) in building
height, required fire pumps shall be supplied by connections to no fewer than two water mains located in different
streets. Separate supply piping shall be provided between each connection to the water main and the pumps.
Each connection and the supply piping between the connection and the pumps shall be sized to supply the flow
and pressure required for the pumps to operate.
Exception: {No change to exception.}
(Reason: The 2009 edition of the IFC added this requirement based on a need for redundancy of the water supply
similar to the redundancy of the power supply to the fire pumps required for such tall buildings, partially due to the
fact that these buildings are rarely fully evacuated in a fire event. More commonly, the alarm activates on the floor
of the event, the floor above and the floor below. Back-up power to the fire pump becomes critical for this reason.
Certainly, the power is pointless if the water supply is impaired for any reason, so a similar requirement is provided
here for redundant water supplies. The 2015 edition changes the requirement to only apply to very tall buildings
over 420 ft. This amendment modifies/lowers the requirement to 120 ft., based on this same height requirement
for fire service access elevators. Again, the language from the 2009 and 2012 editions of the code applied to any
high-rise building. This compromise at 120 ft. is based on the above technical justification of defend-in-place
scenarios in fire incidents in such tall structures.)
**Section 1006.2.2.7; Add Section 1006.2.2.7 as follows:
1006.2.2.7 Electrical Rooms. For electrical rooms, special exiting requirements may apply. Reference the
electrical code as adopted.
Amendments to the 2018 International Fire Code 81
(Reason: Cross reference necessary for coordination with the NEC which has exiting requirements as well.)
**Section 1009.8; add the following Exception 7:
Exceptions:
7. Buildings regulated under State Law and built in accordance with State registered plans, including variances or
waivers granted by the State, shall be deemed to be in compliance with the requirements of Section 1009 and
chapter 11.
(Reason: To accommodate buildings regulated under Texas State Law and to be consistent with amendments in
Chapter 11.)
**Section 1010.1.9.5 Bolt Locks; amend exceptions 3 and 4 as follows:
Exceptions:
3. Where a pair of doors serves an occupant load of less than 50 persons in a Group B, F, M or S occupancy.
(Remainder unchanged)
4. Where a pair of doors serves a Group A, B, F, M or S occupancy (remainder unchanged)
(Reason: Application to M occupancies reflects regional practice; No. 4 expanded to Group A due to it being a
similar scenario to other uses; No. 4 was regional practice.)
**Section 1020.1 Construction; add exception 6 to read as follows:
6. In group B occupancies, corridor walls and ceilings need not be of fire-resistive construction within a single
tenant space when the space is equipped with approved automatic smoke-detection within the corridor. The
actuation of any detector must activate self-annunciating alarms audible in all areas within the corridor. Smoke
detectors must be connected to an approved automatic fire alarm system where such system is provided.
(Reason: Regionally accepted alternate method.)
**Section 1029.1.1.1 Spaces under grandstands and bleachers; delete this section.
(Reason: Unenforceable.)
**Section 1031.2; change to read as follows:
1031.2 Reliability. Required exit accesses, exits and exit discharges shall be continuously maintained free from
obstructions or impediments to full instant use in the case of fire or other emergency where the building area
served by the means of egress is occupied. An exit or exit passageway shall not be used for any purpose that
interferes with a means of egress.
(Reason: Maintain legacy levels of protection and long-standing regional practice, and provide firefighter safety.)
**Section 1103.3; add sentence to end of paragraph as follows:
Provide emergency signage as required by Section 606.3.
(Reason: Coordinates requirements of previous amendment.)
***Section 1103.5.1: add sentence to read as follows:
Fire sprinkler system installation shall be completed within 24 months from date of notification by the fire
code official.
Amendments to the 2018 International Fire Code 82
(Reason: Regional consistency of this retroactive requirement to allow business owners adequate time to budget
to accommodate the cost of the fire sprinkler system.)
**Section 1103.5; add Section 1103.5.5 to read as follows:
1103.5.5 Spray Booths and Rooms. Existing spray booths and spray rooms shall be protected by an approved
automatic fire-extinguishing system in accordance with Section 2404.
(Reason: Consistent with amendment to IFC 2404, and long-standing regional requirement to protect this
hazardous operation.)
***Section 1103.7; add Section 1103.7.7 and 1103.7.7.1 to read as follows:
1103.7.7 Fire Alarm System Design Standards. Where an existing fire alarm system is upgraded or replaced,
the devices shall be addressable. Fire alarm systems utilizing more than 20 smoke and/or heat detectors shall
have analog initiating devices.
Exception: Existing systems need not comply unless the total building, or fire alarm system, remodel or
expansion exceeds 30% of the building. When cumulative building, or fire alarm system, remodel or
expansion initiated after the date of original fire alarm panel installation exceeds 50% of the building, or fire
alarm system, the fire alarm system must comply within 18 months of permit application.
1103.7.7.1 Communication requirements. Refer to Section 907.6.6 for applicable requirements.
(Reason: To assist responding personnel in locating the emergency event and provide clarity as to percentages
of work that results in a requirement to upgrade the entire fire alarm system.)
***Section 1203; change and add to read as follows:
1203.1.1 {No change.}
1203.1.2 {No change.}
1203.1.3 Emergency power systems and standby power systems shall be installed in accordance with the
International Building Code, NFPA 70, NFPA 110 and NFPA 111. Existing installations shall be maintained in
accordance with the original approval, except as specified in Chapter 11.
1203.1.4 through 1203.1.9 {No changes to these sections.}

required by the International Building Code, Section 909.20.6.2.
1203.2.22 Elevator Pressurization. Standby power shall be provided for elevator pressurization system as
required by the International Building Code, Section 909.21.5.
1203.2.23 Elimination of Smoke Dampers in Shaft Penetrations. Standby power shall be provided when
eliminating the smoke dampers in ducts penetrating shafts in accordance with the International Building Code,
Section 717.5.3, exception 2.3.
1203.2.24 Common Exhaust Systems for Clothes Dryers. Standby power shall be provided for common
exhaust systems for clothes dryers located in multistory structures in accordance with the International Mechanical
Code, Section 504.10, Item 7.
1203.2.25 Hydrogen Cutoff Rooms. Standby power shall be provided for mechanical ventilation and gas
detection systems of Hydrogen Cutoff Rooms in accordance with the International Building Code, Section 421.
1203.2.26 Means of Egress Illumination in Existing Buildings. Emergency power shall be provided for means
of egress illumination in accordance with Section 1104.5 when required by the fire code official. (90 minutes in I-
2, 60 minutes elsewhere.)
1203.3 through 1203.6 {No change.}
1203.7 Energy Time Duration. Unless a time limit is specified by the fire code official, in this chapter or elsewhere
in this code, or in any other referenced code or standard, the emergency and standby power system shall be
supplied with enough fuel or energy storage capacity for not less than 2-hour full-demand operation of the system.
Exception: Where the system is supplied with natural gas from a utility provider and is approved.
(Reason: These amendments were moved from Chapter 6, due to relocation of the published sections to this
new Chapter 12. These provisions provide a list to complete and match that throughout the codes. The only
additional requirements are the reference to COPS in NFPA 70, and the specified Energy time duration. Other
changes are a reference to a code provision that already exists.)
**Section 2304.1; change to read as follows:
2304.1 Supervision of Dispensing. The dispensing of fuel at motor fuel-dispensing facilities shall be conducted
by a qualified attendant or shall be under the supervision of a qualified attendant at all times or shall be in
accordance with Section 2204.3. the following:
Amendments to the 2018 International Fire Code 84
1.Conducted by a qualified attendant; and/or,
2.Shall be under the supervision of a qualified attendant; and/or
3.Shall be an unattended self-service facility in accordance with Section 2304.3.
At any time the qualified attendant of item Number 1 or 2 above is not present, such operations shall be considered
as an unattended self-service facility and shall also comply with Section 2304.3.
(Reason: Allows a facility to apply the attended and unattended requirements of the code when both are potentially
applicable.)
**Section 2401.2; delete this section.
(Reason: This section eliminates such booths from all compliance with Chapter 15 including, but not limited to:
size, ventilation, fire protection, construction, etc. If the product utilized is changed to a more flammable
substance, the lack of compliance with Chapter 15 could result in significant fire or deflagration and subsequent
life safety hazard.)
***Section 3103.3.1; delete this section.
(Reason: This new section of the Fire Code requires a fire sprinkler system to be installed in temporary tents and
membrane structures, which is not a reasonable or enforceable requirement for a temporary use. A fire watch or
fire alarm system is a more advisable approach for such occupancies that are only temporary.)
**Table 3206.2, footnote h; change text to read as follows:
h. Not required Where storage areas are protected by either early suppression fast response (ESFR) sprinkler
systems or control mode special application sprinklers with a response time index of 50 (m • s) 1/2 or less that
are listed to control a fire in the stored commodities with 12 or fewer sprinklers, installed in accordance with
NFPA 13, manual smoke and heat vents or manually activated engineered mechanical smoke exhaust
systems shall be required within these areas.
(Reason: Allows the fire department to control the smoke and heat during and after a fire event, while ensuring
proper operation of the sprinkler protection provided. Also, gives an alternative to smoke and heat vents.)
***Table 3206.2, footnote j; add footnote j to row titled ‘High Hazard’ and ‘Greater than 300,000’ to read as
follows:
j. High hazard high-piled storage areas shall not exceed 500,000 square feet. A 2-hour fire wall constructed in
accordance with Section 706 of the International Building Code shall be used to divide high-piled storage
exceeding 500,000 square feet in area.
(Reason: This is a long-standing legacy requirement and provides passive protection for extremely large buildings
where it would be otherwise impossible to control the spread of fire without the fire wall in place in an uncontrolled
fire event, which is much more likely in high hazard commodities, such as tires, flammable liquids, expanded
plastics, etc.)
**Section 3310.1; add sentence to end of paragraph to read as follows:
When fire apparatus access roads are required to be installed for any structure or development, they shall be
approved prior to the time at which construction has progressed beyond completion of the foundation of any
Amendments to the 2018 International Fire Code 85
structure.
(Reason: Reference requirement of Section 501.4.)
**Section 5601.1.3; change to read as follows:
5601.1.3 Fireworks. The possession, manufacture, storage, sale, handling, and use of fireworks are prohibited.
Exceptions:
1.Only when approved for fireworks displays, storage, and handling of fireworks as allowed in Section
5604 and 5608.
2.Manufacture, assembly and testing of fireworks as allowed in Section 5605.
3.2. The use of fireworks for approved fireworks displays as allowed in Section 5608.
4. The possession, storage, sale… {Delete remainder of text.}
(Reason: Restricts fireworks to approved displays only, which is consistent with regional practice. Such is intended
to help protect property owners and individuals from unintentional fireworks fires within the jurisdiction, as well as
to help protect individuals from fireworks injuries. It is noted that there has been a change in the State Law to
allow possession of unopened fireworks in certain areas of the vehicle, and it is highly recommended that AHJ’s
familiarize themselves with the applicable State Laws in this regard.)
**Section 5703.6; add a sentence to read as follows:
5703.6 Piping Systems. Piping systems, and their component parts, for flammable and combustible liquids shall
be in accordance with Sections 5703.6.1 through 5703.6.11. An approved method of secondary containment shall
be provided for underground tank and piping systems.
(Reason: Increased protection in response to underground leak problems and remediation difficulty in
underground applications. Coordinates with TCEQ requirements.)
**Section 5704.2.11.4; add a sentence to read as follows:
5704.2.11.4 Leak Prevention. Leak prevention for underground tanks shall comply with Sections 5704.2.11.4.1
and 5704.2.11.4.2 through 5704.2.11.4.3. An approved method of secondary containment shall be provided for
underground tank and piping systems.
(Reason: Increased protection in response to underground leak problems and remediation difficulty in
underground applications.)
**Section 5704.2.11.4.2; change to read as follows:
5704.2.11.4.2 Leak Detection. Underground storage tank systems shall be provided with an approved method
of leak detection from any component of the system that is designed and installed in accordance with NFPA 30
and as specified in Section 5704.2.11.4.3.
(Reason: Reference to IFC Section 5704.2.11.4.3 amendment.)
**Section 5704.2.11.4.3; add Section 5704.2.11.4.3 to read as follows:
Amendments to the 2018 International Fire Code 86
5704.2.11.4.3 Observation Wells. Approved sampling tubes of a minimum 4 inches in diameter shall be installed
in the backfill material of each underground flammable or combustible liquid storage tank. The tubes shall extend
from a point 12 inches below the average grade of the excavation to ground level and shall be provided with
suitable surface access caps. Each tank site shall provide a sampling tube at the corners of the excavation with
a minimum of 4 tubes. Sampling tubes shall be placed in the product line excavation within 10 feet of the tank
excavation and one every 50 feet routed along product lines towards the dispensers, a minimum of two are
required.
(Reason: Provides an economical means of checking potential leaks at each tank site.)
**Section 5707.4; add paragraph to read as follows:
Mobile fueling sites shall be restricted to commercial, industrial, governmental, or manufacturing, where the
parking area having such operations is primarily intended for employee vehicles. Mobile fueling shall be
conducted for fleet fueling or employee vehicles only, not the general public. Commercial sites shall be restricted
to office-type or similar occupancies that are not primarily intended for use by the public.
(Reason: The general public does not expect a hazardous operation to be occurring in a typical parking lot or for
a fuel truck to be traversing such parking lot, temporarily fueling a vehicle, and moving on to the next area in the
parking lot to fuel the next vehicle. Vehicular accidents occur in parking lots on a regular basis, but the presence
of a fuel truck, especially one in the process of fueling a vehicle with gasoline, greatly adds to the potential risk
involved in such accidents. By restricting such operations to the occupancies in question, the employees of the
business may be adequately notified to expect such operations to occur in the parking lot.)
**Section 6103.2.1; add Section 6103.2.1.8 to read as follows:
6103.2.1.8 Jewelry Repair, Dental Labs and Similar Occupancies. Where natural gas service is not available,
portable LP-Gas containers are allowed to be used to supply approved torch assemblies or similar appliances.
Such containers shall not exceed 20-pound (9.0 kg) water capacity. Aggregate capacity shall not exceed 60-
pound (27.2 kg) water capacity. Each device shall be separated from other containers by a distance of not less
than 20 feet.
(Reason: To provide a consistent and reasonable means of regulating the use of portable LP-Gas containers in
these situations. Reduces the hazard presented by portable containers when natural gas is already available.
Please note that current State Law does not allow for the enforcement of any rules more stringent than that
adopted by the State, so this amendment is only applicable as to the extent allowed by that State Law.)
**Section 6104.2, Exception; add an exception 2 to read as follows:
Exceptions:
1.{existing text unchanged}
2.Except as permitted in Sections 308 and 6104.3.2, LP-gas containers are not permitted in residential
areas.
(Reason: To provide a consistent and reasonable means of regulating the use LP-Gas containers. Reduces the
hazard presented by such containers when natural gas is already available. References regional amendment to
IFC 6104.3.2. Please note that current State Law does not allow for the enforcement of any rules more stringent
than that adopted by the State, so this amendment is only applicable as to the extent allowed by that State Law.)
**Section 6104.3; add Section 6104.3.3 to read as follows:
6104.3.3 Spas, Pool Heaters, and Other Listed Devices. Where natural gas service is not available, an LP-
gas container is allowed to be used to supply spa and pool heaters or other listed devices. Such container shall
not exceed 250-gallon water capacity per lot. See Table 6104.3 for location of containers.
Exception: Lots where LP-gas can be off-loaded wholly on the property where the tank is located may install
up to 500 gallon above ground or 1,000 gallon underground approved containers.
Amendments to the 2018 International Fire Code 87
(Reason: Allows for an alternate fuel source. Dwelling density must be considered and possibly factored into
zoning restrictions. Reduces the hazard presented by over-sized LP-Gas containers. Please note that current
State Law does not allow for the enforcement of any rules more stringent than that adopted by the State, so this
amendment is only applicable as to the extent allowed by that State Law.)
**Section 6107.4 and 6109.13; change to read as follows:
6107.4 Protecting Containers from Vehicles. Where exposed to vehicular damage due to proximity to alleys,
driveways or parking areas, LP-gas containers, regulators and piping shall be protected in accordance with NFPA
58 Section 312.
6109.13 Protection of Containers. LP-gas containers shall be stored within a suitable enclosure or otherwise
protected against tampering. Vehicle impact protection shall be provided as required by Section 6107.4.
Exception: Vehicle impact protection shall not be required for protection of LP-gas containers where the
containers are kept in lockable, ventilated cabinets of metal construction.
(Reason: NFPA 58 does not provide substantial physical protection [it allows raised sidewalks, fencing, ditches,
parking bumpers as ‘vehicle barrier protection’] of the container(s) from vehicular impact as is required and has
been required historically, as per Section 312, i.e. bollard protection. Further, the exception to Section 6109.13
would allow for portable containers in ventilated metal cabinets to not require any physical protection whatsoever
from vehicular impact, regardless of the location of the containers. Please note that current State Law does not
allow for the enforcement of any rules more stringent than that adopted by the State, so this amendment is only
applicable as to the extent allowed by that State Law.)
** {Applicable to those jurisdictions adopting Appendix B}
Table B105.2; change footnote a. to read as follows:
a. The reduced fire-flow shall be not less than 1,000 1,500 gallons per minute.
(Reason: The minimum fire-flow of 1,500 gpm for other than one- and two- family dwellings has existed since the
2000 edition of the IFC, as well as the Uniform Fire Code before that. Little to no technical justification was
provided for the proposed code change at the code hearings. The board believes that the already-allowed 75
percent reduction in required fire-flow for the provision of sprinkler protection is already a significant trade-off. The
minimum 1,500 gpm is not believed to be overly stringent for the vast majority of public water works systems in
this region, especially since it has existed as the requirement for so many years. Further, the continued
progression of trading off more and more requirements in the codes for the provision of sprinkler protection has
made these systems extremely operation-critical to the safety of the occupants and properties in question. In
other words, should the sprinkler system fail for any reason, the fire-flow requirements drastically increase from
that anticipated with a sprinkler-controlled fire scenario.)

replaced with like material, in accordance with the requirements of NFPA 70.

***Section 502.3 Flood Hazard Areas; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city)
**Section 504.1.2; change to read as follows:
504.1.2 Existing fire escapes. Existing fire escapes shall continue to be accepted as a component in the means
of egress in existing buildings only. Existing fire escapes shall be permitted to be repaired or replaced.
(Reason: To add clarity and help reduce confusion associated with the amendment preventing new fire
escapes.)
**Section 504.1.3; delete entire section:
504.1.3 New fire escapes. New fire escapes for existing buildings shall be permitted only where exterior
stairways cannot be utilized due to lot lines limiting stairway size or due to the sidewalks, alleys or roads at grade

installation and connection, joints, penetrations, and continuity of any element, component, or system in the
building.
(Reason: To provide a more complete list of potentially adopted codes.)
***Section 802.5.1; change to read as follows:
802.5.1 Minimum requirement. Every portion of a floor, such as a balcony or a loading dock, open-sided
Amendments to the 2018 International Existing Building Code 96
walking surfaces, including mezzanines, equipment platforms, aisles, stairs, ramps and landings that is more
than 30 inches (762 mm) above the floor or grade below and is not provided with guards, or those in which the
existing guards are judged to be in danger of collapsing, shall be provided with guards.
(Reason: To be consistent with Building Code requirements for guards and unsafe conditions.)
**Section 803.1; add sentence to read as follows:
For the purpose of fire sprinkler protection and fire alarm requirements included in this section, the work area
shall be extended to include at least the entire tenant space or spaces bounded by walls capable of resisting
the passage of smoke containing the subject work area, and if the work area includes a corridor, hallway, or
other exit access, then such corridor, hallway, or other exit access shall be protected in its entirety on that
particular floor level.
(Reason: The intent is to avoid work area protection that would result in partial sprinkler or fire alarm protection.
Partial sprinkler protection not delineated by walls would be a clear violation of NFPA 13 and would not allow
the sprinkler to perform or function as intended. Also, partial fire alarm coverage is a clear violation of the Fire
Code, NFPA 72, and ADA.)
**Section 803.2.4; change exception to read as follows:
Exception: Supervision is not required where the Fire Code does not require such for new construction
for the following:

5. Automatic sprinkler systems installed in accordance with
NFPA 13R where a common supply
main is used to supply both domestic and automatic sprinkler
systems and a separate shutoff
valve for the automatic sprinkler system is not
provided.
(Reason: The published exceptions are over-reaching and will result in inconsistencies among supervised
protection systems and cause confusion for first responders as well.)
**Section 803.3; change section to read as follows:
803.3 Standpipes. Refer to Section 1103.6 of the Fire Code for retroactive standpipe requirements.
{Delete rest of Section 804.3.}
(Reason: The Fire Code already requires standpipes in these buildings (greater than 50 ft.) retroactively in
Section 1103.6. This new section would negate/lessen those retroactive provisions already contained in the
Fire Code.)
**Section 805.2; remove Exception #1
Exception 1. W here the work area and the means of egress serving it complies with NFPA101.
(Reason: NFPA 101 is not a commonly adopted code in the region and enforcement could be problematic.)
**Section 805.3.1.2; change to read as follows:
805.3.1.2 Fire Escapes required. For other than Group I-2, where more than one exit is required an existing
or newly constructed fire escape complying with section 805.3.1.2.1 shall be accepted as providing one of the
Amendments to the 2018 International Existing Building Code 97
required means of egress.
(Reason: Higher level of safety by not allowing new fire escapes.)
**Section 805.3.1.2.1; change to read as follows:
805.3.1.2.1 Fire Escape access and details - …
1. [Remain unchanged]

rooming boarding houses, and childcare centers, ladders of any type are prohibited on fire escapes used as a
required means of egress.

in IBC.)
***Section 805.5.2 Transoms; add language to read as follows:
805.5.2 Transoms. In all buildings of Group B, E, [Remainder unchanged]
(Reason: Transom windows were historically a common practice in school buildings and each jurisdiction
should evaluate the impact on their stakeholders and their community with regards to section.)
**Section 904.1; add sentence to read as follows:
For the purpose of fire sprinkler protection and fire alarm requirements included in this section, the work area
shall be extended to include at least the entire tenant space or spaces bounded by walls containing the subject
work area, and if the work area includes a corridor, hallway, or other exit access, then such corridor, hallway,
or other exit access shall be protected in its entirety on that particular floor level.
(Reason: The intent is to avoid work area protection that would result in partial sprinkler or fire alarm protection.
Partial sprinkler protection not delineated by walls would be a clear violation of NFPA 13 and the Fire Code
and would not allow the sprinkler system to perform or function as intended. Also, partial fire alarm coverage
is a clear violation of the Fire Code, NFPA 72, and ADA.)
**Section 904.1.1; change sentence to read as follows:
904.1.1 High-rise buildings. An automatic sprinkler system shall be provided in work areas of where the high-
rise buildings. has a sufficient municipal water supply for the design and installation of an automatic sprinkler
system at the site.
(Reason: Level 3 alterations are affecting more than 50% of the existing high-rise building, and as such,
sprinkler protection is more than justifiable, even when fire pumps, etc., are necessary. It is noted that the
work area method is one of three different methods available to the designer/owner in the IEBC.)
***Section 1103.3 Flood Hazard Areas; delete this section:
(Reason: Flood hazard ordinances may be administered by other departments within the city.)
***Section 1201.4 Flood Hazard Areas; delete this section:

1301.3.2 Compliance with other codes. Buildings that are evaluated in accordance with this section
shall comply with the International Fire Code. and International Property Maintenance Code.

(Reason: Flood hazard ordinances may be administered by other departments within the city.)
***Section 1402.6 Flood Hazard Areas; delete this section:
