Amendments to the 2021 International Building Code
The following sections, paragraphs, and sentences of the 2021 International Building Code are hereby
amended as follows: Standard type is text from the IBC. Underlined type is text inserted. Lined througI
type is deleted tout from IRr. A double asterisk (**) at the beginning of a section identifies an amendment
carried over from the 2018 edition of the code and a triple asterisk (***) identifies a new or revised
amendment with the 2021 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 Chapter 27 of this code but no longer called by
that name.)
**Section 101.4.8; add to read as follows:
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 no longer published 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:
City of Southlake Buildinq Inspections Department
103.1 Creation of enforcement agency. The [INSERT NAME OF DEPARTMENT] is hereby created and
the official in charge thereof shall be known as the building official.
[Remainder Unchanged]
(Reason: Reminder to be sure ordinance reads the same as designated by the city and amend Section
101.1. )
**Section 105.1; amend to read as follows:
105.1 Required. Any owner or owner's authorized agent who intends to construct, enlarge, alter, repair,
move, demolish, or change the occupancy of a building or structure, to excavate or change the grade of
any property, or to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas,
mechanical or plumbing system, the installation of which is regulated by this code, or to cause any such
work to be done, shall first make application to the building official and obtain the required permit. For
excavation or grading permits see appendix chapter J as adopted.
(Reason: Consistent with previous edition amendment, to provide means to regulate grading affecting
other properties.)
**Section 105.2; Work exempt from permit; under sub -title entitled "Building" delete items 1, 2, 10
and 11 and re -number as follows:

11. and other playgrGund equipment aGG866OFY tG detar--hed- ene- and twG family dwellings.
4-2-. 8.(Unchanged)
4& 9. (Unchanged)
(Reason: Items deleted are for one- and two-family dwellings regulated by the International Residential
Code. 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 107.1; amend to read as follows:
[A] 107.1 General. Submittal documents consisting of construction documents, statement of special
inspections, geotechnical report and other data shall be submitted in two or more sets with each permit
application. The construction documents shall be prepared by a registered design professional in addition
to where required by laws of the State of Texas where -requiredbythe statutes „f the ;, isdi tien uart
the ^rojest is to be ,.enStFUGted including, but not limited to, new construction, alterations and/or
renovations. Architects and engineers shall be required on each project except where otherwise
determined by the building official. Where special conditions exist, the building official is authorized to
require additional construction documents to be prepared by a registered design professional.
Exceptions:
1. The building official is authorized to waive the submission of construction documents and other
data not required to be prepared by a registered design professional if it is found that the nature
of the work applied for is such that review of construction documents is not necessary to obtain
compliance with this code unless otherwise required by state law.
2. Free standing Group U occupancies.
(Reason: To clarify design professional as architect and engineer.
"Section 109; amend 109.4 and add 109.4.1 & 109.4.2 to read as follows:
109.4 Work commencing before permit issuance. Any person who commences work requiring a permit
on a building, structure, electrical, gas, mechanical or plumbing system before obtaining the necessary
permits shall be subject to a fee established by the pliGable gGVeFRiRg ayth„Fity below that
and shall be in addition to the required permit fees.
109.4.1 Investigation. Whenever work for which a permit is required by this code has been commenced
without first obtaining a permit, a special investigation shall be made before a permit may be issued for
such work.
2021 IBC 7
109.4.2 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 work completed up to
the total permit fee as 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.
(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 109; add Section 109.7, 109.8 to read as follows:
109.7 Unauthorized cover up fee. Any work concealed without first obtaining the required inspection in
violation of Section 109 shall be assessed a fee as established by the city fee schedule.
109.8 Re -inspection Fee. A fee as established by city council resolution may be charged when:
1. Work called for inspection is incomplete;
2. Building address and/or permit card is not clearly posted;
3. City approved plans are not on the mob site available to the inspector;
4. The building is locked or work otherwise not available for inspection when called;
5. Items noted for correction on initial inspection and not corrected upon re -inspection.
6. The original red tag has been removed from the iob site and/or,
7. Violations exist on the property including 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 mob site.
(Reason: These fees are not a fine or penalty but are designed to compensate for additional time
necessary to obtain and verify code compliance. Language taken from former Uniform Administrative
Code.)
"Section 110.3.6; Lath, gypsum board and gypsum panel product inspection. Delete exception:
E*c-eption . Gypsum beaFd and gypsum panel PFOdUGtS that aFe not pail of a fire Fes�staRGe Fate
assembhy or a shear assew,hV
(Reason: Lath or gypsum board inspections are not typically performed in this area. Deleting the
exception would then require all gypsum panels to be inspected; this issue is resolved by leaving the
exception intact.)
"Section 111.1; add to read as follows:
111.1 Change of occupancy. A building or structure shall not be used or occupied in whole or in part,
and a change Of GGGUpaRGY in the existing use or occupancy classification, or occupant or owner, of a
building or structure or portion thereof shall not be made, until the building official has issued a certificate
of occupancy therefor as provided herein. {Remainder unchanged}
Exceptions:
1. Certificates of occupancy are not required for work exempt form permits in accordance with Section
105.2.
2. Office occupancies, excluding medical care uses, which are not part of a mixed -use occupancy such
as office/warehouse and there is no change in electric or gas meter accounts.
(Reason: The IBC as written only requires a Certificate of Occupancy for new buildings, remodeled
buildings, or buildings where the occupancy classification changes. Historically, Southlake has required
that a Certificate of Occupancy be issued for a change in the business occupying the property even if the
change was still within the same occupancy group. This amendment would exempt simple tenant
changes other than medical occupancies where there is no occupancy type change and there is no
change in billing of metered utilities for electricity gas or water. Typical bills paid spaces rented for
executive suites or mini warehouses would not require a certificate of occupancy.)
2021 IBC 8
"Section 202; amend definition to read 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. This group may include but not be limited to the following:
- Dialysis centers
- Procedures involving sedation
- 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 sedated 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 administered moderate sedation and/or
general anesthesia 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 administered
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 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. Corresponds with IFC
202.
"Section 202; amend definition to read as follows:
HIGH-RISE BUILDING. A building with an occupied floor located more than 7-5 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 firefighting
caaabilities of a iurisdiction. Corresponds with IFC 202.)
"Section 202; amend definition to read as follows:
REGISTERED DESIGN PROFESSIONAL. An individual who is registered or licensed to practice their
respective profession as defined by the stat„t„r„ Fequireme.nts „f the Texas Board of Architectural
Examiners or the Texas Board of Professional Engineers, professionals are those that are roe„lato,� h„

(Reason: To clarify that registered design professionals are those who are regulated by the Texas Board
of Architectural Examiners or the Texas Board of Professional Engineers.)
"Section 202; amend definition to read 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 IFC 202.)
2021 IBC 9
**Section 202; amend definition 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 303.1.3; amendto 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 Chapter 10 and 11.
(Reason: To clarify that egress and accessibility requirements are applicable for assembly areas, i.e.
cafeteria, auditoriums, etc.)
**Section 304.1; Business Group B add to read as follows:
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; High -Hazard Group H amend to read as follows:
Exception:
{previous exceptions unchanged)
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.)
i
**Section 403.1; High -Rise Building; amend to read as follows:
Exception:
{previous exceptions unchanged)
3.The open air portion of a building [remainder unchanged]
(Reason: To clarify enclosed portions are not exempt.)
**Section 403.3; Automatic sprinkler system; delete Exception.
(Reason: To provide adequate fire protection to enclosed areas.)
**Section 403.3.2; amend 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.)
2021 IBC 10
(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 403.3.2; change to read as follows:
Section 404.10 Exit Stairways in an atrium. Where an atrium contains an Interne r exit access stairway
all the following shall be met:
[Remainder Unchanged]
(Reason: The five provisions within Section 404.10 are applicable to exit access stairways, not interior
exit stairways. As printed, this is an error, that if left uncorrected, would change among other core code
provisions, how to measure travel distance to an enclosed exit stairway. There is use of the terms "exit
stairway in an atrium" vs. `interior exit stairway" vs. "exit access stairway" that will cause confusion as to
which provisions are applicable.)
**Section 406.3.3.1; Carport separation; add 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.)
***Section 423.5.1; change to read as follows:
423.5.1 Required occupant capacity. The required occupant capacity of the storm shelter shall include
all of the buildings on the site and shall be the greater of the f„ll,,,.,iRg;
I The Total occupant load of the classrooms, vocational rooms and offices in the Group E occupancy.
2.The eGG61paRt lead ef the largest iRdoor assembly spaGe that is asser.1-ated- ihdth the Greup F. GGG61paRGY.
Exceptions:
1. Where a new building is being added on an existing Group E site, and where the new building is not of
sufficient size to accommodate the required occupant capacity of the storm shelter for all of the buildings
on the site, the storm shelter shall at a minimum accommodate the required occupant capacity for the
new building.
2_ Where approved by the building official, the required occupant capacity of the shelter shall be permitted
to be reduced by the occupant capacity of any existing storm shelters on the site.
3. Where approved by the building official, the actual number of occupants for whom each occupied
space, floor or building is designed, although less than those determined by occupant load calculation,
shall be permitted to be used in the determination of the required design occupant capacity for the storm
shelter.
Reason: The language in the new exception is parallel to the language in Chapter 10 that gives an AHJ
similar authority for fire egress occupant load, clarifying that an AHJ has the authority to reduce the
required shelter occupant capacity based on rationale provided by a School District.)
**Section 502.1; amend to read as follows:
2021 IBC 11
502.1 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. Ad-d—ress; id-o^+;f;,..,t;A-.n ,.har".ors shall rAntrA.Q;t with their baGkgF,,61,,�

--A-Ghes (102 mm) high with minimurn stroke width of 1,42
. (Remainder of text unchanged) See Ordinance # 441 for specific addressing requirements.
(Reason: Call attention to addressing ordinance. Also matches amendment to IFC 505.1
'Section 503.1.; add sentence to read as follows:
503.1. General. [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,
except as allowed in Section 510.
(Reason: To create definite language that requires separation between dissimilar building types.)
** Table 506.2; delete footnote i from table
The maximum allewable area fer a SiRgle story nGR sprinklered Greup U greenheuse is permitted te be
9000 square fp-et P-.r thte a.rea shall be permitted W GOMPlY with Table G102.1 of Appendix G.
(Reason: To eliminate the need for Appendix C adoption and remain consistent with 6000 sq. ft.
s rinklerin rovision.)
"Section 506.3.1; add to read as follows:
506.3.1 Minimum percentage of perimeter. To qualify for an area factor increase based on frontage, a
building shall have not less than 25 percent of its perimeter on a public way or open space. Such open
space shall be either on the same lot or dedicated for public use and shall be accessed from a street or
approved fire lane. 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 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 draftstopping. [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 draftstopping. For this reason, omission of sprinklers permitted in accordance with NFPA 13
referenced standard should not be permitted with IBC exception requiring draftstopping in combustible
construction.)
2021 IBC 12
"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 IBC 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 IBC code.)
'Section 903.1.1; amend to read as follows:
[F] 903.1.1 Alternative protection. Alternative automatic fire -extinguishing systems complying with
Section 904 shall be permitted instead e 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 in
general. 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. This also meets with local practices in the region.)
"Section 903.2; add paragraph to read as follows and delete the exception for
telecommunications buildings:
[F] 903.2 Where required. Approved automatic sprinkler systems in new buildings and structures shall
be provided in the locations described in Sections 903.2.1 through 903.2.12. 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 3006.5 for the purpose of elevator passenger and firefighter safety.
This amendment is contingent on the Building Code amendment eliminating the Exceptions to Section
3006.4, 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 903.2.4.2; change to read as follows:
903.2.4.2 Group F-1 distilled spirits. An automatic sprinkler system shall be provided throughout a
Group F-1 fire area used for the manufacture of distilled spirits involving more than 120 gallons of distilled
spirits (>16% alcohol) in the fire area at anv one time.
(Reason: To establish a sprinkler criteria limit based on existing maximum allowable quantities provided
for flammable liquids in a non-sprinklered space from Chapter 50 and allow very small distillery type
operations without sprinkler requirements as has been historically allowed.)
'Section 903.2.9.3; change to read as follows:
2021 IBC 13
903.2.9.3 Group S-1 distilled spirits or wine. An automatic sprinkler system shall be provided
throughout a Group S-1 fire area used for the bulk storage of distilled spirits or wine involving more than
120 gallons of distilled spirits or wine (>16% alcohol) in the fire area at any one time.
(Reason: To establish a sprinkler criteria limit based on existing maximum allowable quantities provided
for flammable liquids in a non-sprinklered space from Chapter 50 and allow very small storage operations
without sprinkler requirements as has been historically allowed.)
**Section 903.2.9; delete Exception for 903.2.9.4 add 903.2.9.5 to read as follows:
[F] 903.2.9.5 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; amend 903.2.11.3 and add 903.2.11.7, 903.2.11.8, and 903.2.11.9 to read 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 GGGUpaRt lead of 30 er mere 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. QGGYpandes OR r_re p G_2
903.2.11.7 High -Piled Combustible Storage. For any building with a clear height exceeding 12 feet
(4572 mm), see Chapter 32 of the IFC 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-extinauishina system.
903.2.11.9 Buildings Over 6,000 Square Feet. An automatic sprinkler system shall be installed
throughout all buildings over 6,000 sq. ft. For the purpose of this provision, fire walls shall not define
separate buildings. For this section only, area measurement shall be based on outside dimensions of
exterior walls, exclusive of vent shafts and courts, without deduction for corridors, stairways, closets, and
the thickness of interior walls, columns or other features. The floor area of a building, or portion thereof,
not provided with surrounding exterior walls shall be the usable area under the horizontal projection of the
roof or floor above. For upper level attic type rooms, areas where the ceiling height is less than five feet
(5' 0") shall not be considered. Unfinished space framed to permit future expansion of floor area shall be
considered as part of the area. Joists designed to support floor loads shall be assumed to be for future
area.
Exceptions:
1. Open parking garages in compliance with IBC Section 406.3.
2. Building regulated under the International Residential Code as amended.
(Reason: Reflects regional practices. 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; amend to read as follows:
[F] 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.
2021 IBC 14
1. A room where the application of water, or flame and water, constitutes a serious life or fire
hazard.
2. A room or space where sprinklers are considered undesirable because of the nature of the
contents, when approved by the 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. Reems er areas that -Are A-f nenGGmbustible GGRStFUGtien with whGIIY RenGGmbustible Gentents.
5. Fore seFVOGe aGGess 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 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; change to read as follows:
903.3.1.2 NFPA 13R sprinkler systems. Automatic sprinkler systems in Group R occupancies shall
be permitted to be installed throughout in accordance with NFPA 13R where the Group R occupancy
meets all of the following conditions:
1. Four stories or less above grade plane.
2. The floor level of the highest story is 30 35 feet (9144 10668 mm) or less above the lowest level of
fire department vehicle access.
3. The floor level of the lowest story is 30 35 feet (9144 10668 mm) or less below the lowest level of
fire department vehicle access.
{No change to remainder of section.)
(Reason: The change to the 2021 /FC over -reached to limit 13R systems to 30 ft. high at topmost floor
level, which basically results in limiting 13R systems to 3 story buildings in reality. This change to 35 ft.
would still allow 13R systems in 4 story apartment buildings, as has been allowed historically and as
intended by 13R's scope.)
'Section 903.3.1.2.2; change to read as follows:
903.3.1.2.2 Corridors and balconies in the means of egress. Sprinkler protection shall be provided in
all corridors and for all balconies. OR the meaRS of egress where any of the felle,. iRg ,.,,.,,bons app
{Delete the rest of this section.)
(Reason: Corridor protection is critical to the means of egress, and corridors are regularly utilized for
miscellaneous storage, fixtures, artwork, food kiosks and beverage dispensers, and furnishings. Balcony
protection is required due to issues with fire exposure via soffit vents and the potential for significant
combustible loading.)
"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
2021 IBC 15
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; amend to read as follows:
[F] 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 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, preaction, 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:
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 larae diameter water -filled pipe.
(Reason: In the last few years, severe winters brought to light several issues with current practices for
sprink/ering 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; Water supplies; add to read as follows:
[F] 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
desianed with a 10 psi safetv factor. Reference Section 507.4 for additional desian reauirements.
(Reason: To define uniform safety factor.
"Section 903.4; Sprinkler system supervision and alarms; add after the exceptions to read as
follows:
[F] 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; Alarms; add to read as follows:
2021 IBC 16
[F] 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 905.1; add to read as follows: 905.1.1
905.1.1 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
when foreign material is present, 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. Corresponds to IFC 901.6.1.)
**Section 905.2; amend to read as follows:
[F] 905.2 Installation standard. Standpipe systems shall be installed in accordance with this section and
NFPA 14. Fire department connections for standpipe systems shall be in accordance with Section 912
2021 IBC 17
Manual dry standpipe systems shall be supervised with a minimum of 10 psiq and a maximum of 40 psiq
air pressure with a high/low alarm.
(Reason: To define manual dry standpipe supervision requirements. Helps ensure the integrity of the
standpipe s stem via supervision, such that open hose valves will result in a su erviso low air alarm.
"Section 905.3; add to read as follows:
[F] 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 and semi -automatic dry standpipes are allowed as provided for in NFPA 14.
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.)
"Section 905.4; Location of Class I standpipe hose connections; amend to read as follows:
[F] 1. In every required inter+er exit stairway, a hose connection shall be provided for each story above
and below grade. 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
feterier 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 fnterier 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 905.8; change to read as follows:
905.8 Dry standpipes. Dry standpipes shall not be installed.
Exception: Where subject to freezing and in accordance with NFPA 14. Additionally, manual dry
standpipe systems shall be supervised with a minimum of 10 psiq and a maximum of 40 psiq air
pressure with a high/low Supervisory 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.
NFPA 14 requires supervisory air for such but does not provide pressure criteria for what that means.
This is a long-standing regional requirement.)
"Section 905.9; Valve supervision; add after the exceptions to read as follows:
Kier system and Snail cause an warm UDon detection of water tiow for more tnan 45 secon S.
2021 IBC 18
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.
or In L
***Section 906.1(1); delete Exception #3 as follows:
(Reason: This provision of only having vehicle -mounted fire extinguishers is not at all consistent with
historical practice of requiring extinguishers throughout based on travel distance. Often times, the vehicle
is what has caused the incident and/or may be the source of the incident, so having the extinguisher
vehicle -mounted results in greater potential injury of the user. This assumes the only occupants in the
building are on a vehicle, which again, significantly reduces access to fire extinguishers throughout the
building to other occupants. Future use of the building/tenancy may change further complicating the
issue.)
vSection 907.1; add to read as follows:
[F] 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; amend to read as follows:
[F] 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 having an occupant
load d, +^ the bly eGG61PaRGY ;s of 300 or more persons or 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.)
2021 IBC 19
"Section 907.2.3; amend to read as follows:
[F] 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 907.2.10; change to read as follows:
907.2.10 Group S. A manual fire alarm system that activates the occupant notification system in
accordance with Section 907.5 shall be installed in Group S public- and self -storage occupancies three
st ries r greater in height for interior corridors and interior common areas. Visible notification appliances
are not required within storage units.
Exception: {No change.)
(Reason: Because of the potential unknown fire load and hazards in self -storage type facilities, which
could include flammable liquids for instance, as well as other hazardous materials, prompt evacuation in
the event of fire alarm is needed; therefore, notification in the corridors/common areas is critical to all
such occupancies, regardless of height.
"Section 907.2.13; High-rise buildings; amend to read as follows:
Exception:
{previous exceptions unchanged}
[F] 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 to read as follows:
[F] 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 to read as follows:
[F] 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
2021 IBC 20
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; Initiation device identification; delete all four Exceptions.
(Reason: To assist responding personnel in locating the emergency event for all fire alarm systems.)
**Section 907.6.6; Monitoring; add sentence at end of paragraph to read as follows:
[F] 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
was moved from 907.6.5.3 in the 2012 IFC and reworded to match new code lan ua a and sections.
**Section 910.2; Smoke and Heat Removal Where required; amend to read as follows:
Exceptions:
{previous exceptions unchanged)
[F] 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)112 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 to read as follows:
[F] 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 910.4.3.1; amend to read as follows:
[F] 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 mom,; —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.
2021 IBC 21
(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 910.4.4; amend to read as follows:
[F] 910.4.4 Activation. The mechanical smoke removal system shall be activated by manual GeRtre'S
only automatically by the automatic sprinkler system or by an approved fire detection system. Individual
manual controls shall also be provided.
Exception: Manual only systems per Section 910.2.
(Reason: The provision of a manual only mechanical smoke removal system does not provide
equivalency with automatic smoke and heat vents. This amendment clarifies that the primary intent is for
automatic systems, unless exceptions are provided as in 910.2 — consistent with the charging statements
of the section.)
"Section 912.2; add to read as follows:
[F] 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:
[F] 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 Section 506.1.
3. 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 1006.2.1 change exception 3 to read as follows, -
Section 1006.2.1 Egress based on occupant load and common path of egress travel distance.
Exceptions:
3. Unoccupied rooftop mechanical rooms and penthouses are not required to comply with the common
path of egress travel distance measurement.
(Reason: Add "rooftop" to Exception No. 3 to clarify that only such mechanical rooms located on the roof
maybe exempted.)
*'Section 1009.8 Two Way Communication; add the following Exception 7:
Exceptions:
2021 IBC 22
(previous exceptions unchanged}
7. Buildings regulated under State Law and built in accordance with State registered
plans, including any variances or waivers granted by the State, shall be deemed to
be in compliance with the requirements of Section 1009.
(Reason: To accommodate buildings regulated under Texas State Law and to be consistent with
amendments to Chapter 11.
**Section 1010.2.5; Bolt Locks; amend to read as follows:
Exceptions:
(previous exceptions unchanged}
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: It is common in our region to see the 2nd leaf locked, when that leaf is not part of the required
egress door clear width, such as in a typical Group M. Exception No. 4 was expanded to Group A due to
it being a similar situation for Group A restaurants.
**Section 11015.8; Window Openings. Amend to read as follows:
1. Operable windows where the top of the sill of the opening is located more than 75 feet
(22,860 ems) 55 feet (16,'� 64 mm ) above the finished grade or other surface below and
that are provided with window fall prevention devices that comply with ASTM F 2006.
Reason: In Option B jurisdictions, change 75 feet" to "55 feet".
**Section 1020.2 Construction; add exception 6 as follows:
6. In unsprinklered 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: Similar concept was previously in UBC. This scenario occurs primarily in existing, non-
sprinklered buildings, which under current IBC would be required to have a fire resistance rated corridor.
New exception provides a cost-effective solution for single tenant space in lieu of the base IBC
requirement to retrofit a fire sprinkler system throughout the building.)
**Section 1030.1.1.1; Delete section: Spaces under grandstands and bleachers.
Reason: Unenforceable.
***Section 1102.0; add exception to read as follows:
Exception: Projects subject to the Texas Accessibility Standards as adopted by the Texas
Department of Licensing and Regulation are exempt from this section. Protects with a valuation of
less than $50,000.00 (which are subject to the Texas Accessibility Standards) may be accepted as
equivalent to this section where reviewed and inspected to the Texas Accessibility Standards by a
Texas Department of Licensing and Regulation Registered Accessibility Specialist when a plan
review report and a compliant inspection report are provided to the building code official.
(Reason: To coordinate with State Law for accessibility.)
2021 IBC 23
***Section 1809.5.1 Frost Protection at required exits; delete this section
(Reason: frost protection at exit doors is not needed in our climate zone.
***Section 2702.5; added to read as follows:
Section 2702.5 Designated Critical Operations Areas (DCOA): In areas within a facility or site
requiring continuous operation for the purpose of public safety, emergency management, national
security or business continuity, the power systems shall comply with NFPA 70 Article 708.
(Reason: Identifying these areas of critical operations in the building code ensures designers are advised
of the requirements outlined in the National Electrical Code which defines specific Critical Operations
Power System (COPS) requirements.)
**Section 2901.1; add 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 discretion to Code Official in case of code conflict.)
**Section 2902.1; Minimum number of fixtures; 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 f to read as follows:
q. 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.)
**Section 2902.1.4; add 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.
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 Tarrant County 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.)
2021 IBC 24
**Section 3002.1; Hoistway Enclosure Protection; add to read as follows:
Exceptions:
1. Elevators wholely located within atriums complying with Section 404 shall not require hoistwa
enclosure protection.
2. Elevators in open or enclosed parking garages that serve only the parking garage, and complying
with Sections 406.5 and 406.6, respectively, shall not require hoistwav enclosure protection.
(Reason: Provides specific Code recognition that elevators within atriums and within parking garages do
not require hoistway enclosure protection.)
**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 reauire 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.
(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 3005.5; Add a new subsection to Section 3005.5.1 as follows:
3005.5.1 Fire Protection in Machine rooms. control rooms. machinery spaces and control spaces.
3005.5.1.1 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 3005.5.1.1.1.
3005.5.1.1.1 Prohibited locations. Automatic sprinklers shall not be installed in machine rooms, elevator
machinery spaces, control rooms, control spaces and elevator hoist -ways.
3005.5.1.1.2 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.
3005.5.1.2 Water protection. An approved method to prevent water from infiltrating into the hoistwav
enclosure from the operation of the automatic sprinkler system outside the elevator lobby shall be
provided.
3005.5.1.3 Omission of 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 3005.7; add to read as follows:
3005.7 Storage. Storage shall not be allowed within the elevator machine room, control room, machinery
2021 IBC 25
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; amend to read as follows:
5. The building is a high rise and the elevator hoistway is more than 75 fee t (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: 20181BC text does not address hoistways that are > 75' in height that are both below grade and
above grade but not located above the high rise classification nor does the IBC address hoistways
wholely located above grade such as those that serve above sky lobbies.)
***Section 3007.3 and Section 3008.3: Revise text by deleting "enclosed" as follows:
3007.3 Water Protection. Water from the operation of an automatic sprinkler system outside the
^yea lobby shall be prevent from infiltrating into the hoistway enclosure in accordance with an
approved method.
3008.3 Water Protection. Water from the operation of an automatic sprinkler system outside the
8^�d lobby shall be prevent from infiltrating into the hoistway enclosure in accordance with an
approved method.
(Reason: The lobbies for FSAE and or OEE elevators may be open (i.e., at ground level), or may not
require a lobby enclosure on those upper floors with secondary cab entry doors opening into a
nonrequired FSAE or OEE lobby. Regardless of whether or not the lobby is enclosed, the objective is to
preclude fire sprinkler water from entering into the hoistway serving FSAE and OEE elevators. The
deletion of "enclosed" clarifies the original intent of this provision and is consistent with ICC
interpretations.
