Fire code compliance
in Austin.

Austin Fire Department
Fire Marshal's Office.

The Austin Fire Department Fire Marshal's Office is responsible for protection of life and property through code enforcement, plans review, fire inspections, and fire cause determination across the City of Austin.

Functional responsibilities

• Code enforcement — application of 2024 IFC + 2024 WUIC + Austin local amendments
• Plans review — fire and life safety plan review for new construction, renovations, and major modifications
• Fire inspections — annual and complaint-driven inspections of commercial occupancies
• Fire cause determination — investigation following fires
• Special events permitting — temporary events, public assemblies
• Emergency planning — building emergency plans submitted to AFD
• Wildland-Urban Interface review — through the WUI Plans Examiner team

Key operational areas commercial operators commonly engage

• Inspections — fire/life safety inspections by AFD inspectors
• Special Events — fire code requirements for temporary events
• Emergency Planning — building emergency plan submission
• KNOX Box program — secure key access for monitored fire alarm/sprinkler buildings (managed by AFDKNOXprogram@austintexas.gov)

WUI specifically: Austin Fire Department operates a dedicated WUI Plans Examiner program. Beth Culver serves as the lead WUI Plans Examiner, overseeing WUI code review and implementation including development of local amendments. Operators with properties in any of the three WUI Proximity Zones should plan for engagement with this team during construction, additions, or remodels.

2024 International Fire Code —
Effective July 10, 2025.

The Austin City Council on April 10, 2025 repealed and replaced Article 7 (Fire Code) of City Code Chapter 25-12 with the 2024 International Fire Code and Austin local amendments. Implementation became effective July 10, 2025.

Recommendation rationale (from Council documentation):

“The International Fire Code (IFC) provides minimum requirements to address the design and construction of commercial buildings. The proposed ordinance reduces local amendments and clarifies existing amendments.”

This dual goal — adopting the latest national code while reducing local amendment burden — is distinctive. Many cities accumulate local amendments over time, complicating compliance. Austin's approach explicitly clarifies and reduces.

Significant changes commercial operators should understand

• Flammable Gas categories — adds definition and requirements for Flammable Gas Categories 1A and 1B
• Open parking garage sprinkler requirements — new provisions for parking garage construction
• Lithium battery fire protection — fire protection requirements of storage of lithium batteries in Group B (Business), F-1 (Factory/Industrial), M (Mercantile), and S-1 (Storage) occupancies
• CO detection and systems — adopting 2021 IFC requirements for carbon monoxide detection and systems
• Mass Notification — deleting Mass Notification requirements for E (Educational) occupancies
• Animal Care Facility — new fire protection requirements
• Hazardous materials on rooftops — maximum allowable quantity provisions
• Title 25 “HOME” Initiative interaction — local amendments addressing methods to mitigate WUI risks for new development under the recent Austin housing reform

Fire Protection Criteria Manual transition

Austin Fire is currently revising and updating the Fire Protection Criteria Manual through the City's rule-making process. In the interim, the 2012 Fire Protection Criteria Manual can still be used for guidance in the application of the 2024 IFC and local amendments. Updates throughout 2026 will replace remaining sections.

This interim status creates compliance uncertainty for some projects. Commercial operators should:

• Reference the 2024 IFC and Austin local amendments as primary
• Use the 2012 FPCM as supplementary guidance where the 2024 IFC is silent
• Subscribe to Development Services' Building Connections newsletter for FPCM update notifications
• Engage AFD directly for code interpretation when ambiguity exists

2024 Wildland-Urban
Interface Code.

Austin was the first major city in Texas to adopt the International Wildland-Urban Interface Code, initially in 2020. The 2024 WUIC (effective July 10, 2025, replacing the 2015 WUIC) reflects updated wildfire science, expanded protections, and clearer compliance pathways.

Three Proximity Zones

(Replacing prior “Proximity Classes” terminology):

Each zone has site, infrastructure, and structure hardening requirements. Compliance burden generally increases as you approach wildland.

Significant 2024 WUIC changes

• Ember Ignition Zone (EIZ) Section 603.2.1 — NEW concept addressing the noncombustible zone immediately surrounding structures. Critical for understanding modern wildfire defense
• Performance and prescriptive vent requirements — Sections 504.10, 505.10, 506.5; 1/8″ max mesh openings aligned with current Austin regulation
• Zone-specific separate code sections — Section 504 for Zone A, Section 505 for Zone B, Section 506 for Zone C (replacing earlier consolidated approach)
• Modified accessory structure protection — for Zones A & B
• Enhanced wall protection — for Zone B
• Enhanced eave and ceiling protection — for Zone C
• Reduced roofing, underfloor enclosure, slope requirements — for Zone C
• Driveways — serve up to maximum of 3 dwelling units, or provide full-width fire lane
• Reduced full roof replacement requirement
• Reduced boat dock requirements
• Wildfire Defense Mesh (IBHS technology) — referenced in EIZ provisions

Retroactivity

Under WUIC 101.4, the code applies only to new development and construction beginning on or after July 10, 2025, including projects where a permit application is submitted on or after that date. Existing buildings and conditions are not required to comply unless a code official determines they pose a serious danger or extreme hazard to life or property.

Determining your zone

Austin Fire publishes a 2024 WUI Code Interactive Map. Properties can confirm zone designation by entering address. The 2024 map includes new “offset” or “buffer zone” visualization to clarify zone boundaries that the 2015 map left ambiguous.

Volume Builder Program transition

Volume Builder Master Plans submitted before July 10, 2025 may continue following the 2021 Residential Code, other adopted 2021 technical codes, and the 2015 WUIC for individual building permit applications in that subdivision or site plan section/phase. Master Plan Applications submitted on or after July 10, 2025 must follow the 2024 technical codes.

KNOX Box
Requirements.

Per Austin Fire Code (LCD CH. 25-12, Article 7) Reference Section 506, KNOX boxes are required at every structure or property where access is made difficult or that has a monitored fire alarm or sprinkler system.

KNOX Box program details

• AFD does not install, relocate, or repair KNOX products — operators must engage authorized vendors
• KNOX Boxes: order at KNOXbox.com/austinfire-boxes
• FDC Locks, Gate & Key Switches, Padlocks: order at KNOXbox.com/austinfire
• Service requests: submit via the AFD KNOX Program Service Request form
• Mounting and key access requirements: AFD publishes a PDF guide
• General questions: AFDKNOXprogram@austintexas.gov

Why this matters: KNOX Box compliance is a frequently overlooked requirement that surfaces during AFD inspections. Buildings with monitored fire alarm or sprinkler systems are required to have compliant KNOX Box installation regardless of property age. Discovery during inspection without compliant installation results in violation.

Annual inspection reporting: Fire agencies reporting KNOX Key Annual Inspections submit through the appropriate AFD form. Building owners should ensure their service vendors complete this reporting on schedule.

Common Violations in
Austin Commercial Properties.

AFD's most frequently cited violations reflect the city's unique compliance profile during the 2024 IFC transition.

1. Compliance confusion during IFC 2024 transition — operators still referencing older IFC editions or using the 2015 WUIC where 2024 WUIC now applies. The transition is recent enough (July 2025) that some service providers have not fully updated practice.

2. Wildland-Urban Interface compliance failures — properties in Proximity Zones A, B, or C without proper structure hardening, defensible space, or ember ignition zone management. Particularly common in suburban and exurban commercial properties.

3. KNOX Box non-compliance — buildings with monitored fire alarm/sprinkler systems lacking compliant KNOX Box installation. Frequently discovered during routine annual inspections.

4. Fire Protection Criteria Manual interim period confusion — some commercial operators are uncertain whether to follow the 2012 FPCM or wait for updated guidance. AFD direction: 2024 IFC + Austin local amendments are primary; 2012 FPCM is supplementary guidance only.

5. Special event fire code compliance failures — restaurants doing pop-ups, venues hosting events, conferences in non-traditional spaces — all require AFD fire code review with specific assembly load and egress provisions.

6. SFMO Alarm Certificate of Registration verification failures — building owners engaging unlicensed fire alarm contractors. Texas-wide requirement under Insurance Code Chapter 6002.

7. Sprinkler coverage deficiencies in rapidly converted commercial spaces — Austin's tech-driven growth has created many warehouse-to-office and warehouse-to-residential conversions where original sprinkler coverage doesn't meet new occupancy classification.

8. Hot work without permits — construction-active commercial environments cite frequently for welding, cutting, brazing without required permits.

Stakeholder Engagement
and Public Input.

Austin Fire Department is notably active on community outreach during the IFC 2024 transition and ongoing FPCM updates. Commercial operators benefit from direct engagement.

Stakeholder engagement channels

• Building Connections newsletter (Development Services) — formal Feedback and Engagement Opportunities
• Public input platforms — speakupaustin.org for active code change consultations
• Technical Advisory Review Panel (TARP) — technical review meetings preceding final code adoption
• WUI Code presentations — recorded video presentations + written FAQ documents available on AFD website

Why this matters: Operators who engage early in the public input process can influence Austin local amendments before adoption. The 2024 WUIC adoption process incorporated significant stakeholder feedback through multiple revision cycles. Operators with significant Austin commercial portfolios should subscribe to Building Connections and monitor speakupaustin.org for upcoming code change opportunities.

Currently in active public input (as of late 2025):

• 2024 WUIC Criteria Manual update — Beth Culver and AFD staff incorporating public input through Technical Advisory Review Panel meetings
• Additional FPCM section updates throughout 2026

Beyond Austin City Limits —
Travis County and Surrounding Jurisdictions.

Austin commercial properties outside city limits fall under varying jurisdictions. Operators with properties in suburbs and unincorporated Travis County should know which AHJ applies.

• City of Austin — Austin Fire Department under 2024 IFC + 2024 WUIC
• Travis County (unincorporated) — Travis County Fire Marshal Office, generally following Texas SFMO framework with local amendments
• Suburban municipalities — Round Rock, Pflugerville, Cedar Park, Leander, Bee Cave, West Lake Hills each operate their own fire departments and AHJs

For multi-property portfolios spanning these jurisdictions, dual or multi-AHJ compliance documentation is required. Round Rock, Pflugerville, and Cedar Park have not (as of this guide) adopted the 2024 IFC; operators should verify the applicable code edition for each jurisdiction.
