Houston Fire Marshal vs. Harris County Fire Marshal: who is your AHJ?

"Houston" on a mailing address does not tell you which fire marshal enforces the fire code at a building. Many Houston addresses sit outside the city limits, in unincorporated Harris County. The authority having jurisdiction (AHJ) decides which fire code applies, where inspection reports go and who you call about a red tag. This guide shows how to tell the two apart.

Every rule on this page links to its public source. It is general information, not legal advice. FireMarket does not file inspection reports with any AHJ.

The short version

Sources: HFD Houston Fire Marshal Office; HCFMO Brycer / The Compliance Engine page; HCFMO fee schedule header (address and phone).

Other incorporated cities inside Harris County have their own fire marshal. If the building is in one of them, check that city's fire marshal, not HFD or HCFMO.

Step 1: Find out which side of the line you are on

The Harris County Fire Code applies in the unincorporated area, defined as the part of Harris County that is not inside an incorporated city, town or village (or within 2,500 feet of the centerline of the Houston Ship Channel) (Harris County Fire Code).

HCFMO's FAQ gives a quick test: look the address up in the Harris County address search. If the "Law Juris" column contains "sheriff," the building is in unincorporated Harris County (HCFMO FAQ).

Step 2: Know what each AHJ expects

Unincorporated Harris County (HCFMO)

• Every ITM report goes through The Compliance Engine. HCFMO requires all service providers who inspect or test fire protection systems in its jurisdiction to register and submit test, inspection and service reports through TCE (HCFMO).
• Yellow and red tag notices go through the same platform, and that counts as the AHJ notification required by State rules (Harris County Fire Code §109.3.1).
• Records: keep at least 3 years (§109.3).

Full details: Harris County Fire Code §109.3.1: ITM reporting through The Compliance Engine.

Inside the City of Houston (HFD Fire Marshal's Office)

HFD's Life Safety Bureau Standard 02, "Inspection and Testing of Fire Protection and Life-Safety Equipment" (HFD LSB Standard 02, Rev 03), sets the City's expectations:

• The owner is responsible for having systems inspected, tested and maintained, and for giving access (§2.1.3).
• Only State-licensed companies may service automatic fire sprinkler, fire alarm and fire extinguisher systems (§2.3.1).
• Keep records at least 3 years and make them available to the fire department on request (§2.3.5).
• Red tags: the registered firm notifies the owner immediately and the Fire Marshal's Office within 24 hours by phone, fax or email, then sends a copy of the written notice within 3 business days (§2.3.2.1).
• Systems out of service: call HFD's Office of Emergency Communications at 713-884-3143 when a required system goes out of service for emergency or unscheduled work, and again when it is restored. Give the Fire Marshal's Office written notice at least 7 business days before planned, lengthy work (§2.3.6).

Reporting inside Houston. We did not find a City of Houston publication, as of October 13, 2026, that requires contractors to submit routine ITM reports through The Compliance Engine. Brycer has publicly described implementing TCE with HFD's Life Safety Bureau, so ask your contractor how they report Houston jobs and confirm with HFD's Life Safety Bureau at 832-394-6900 (HFD Fire Marshal's Office).

Step 3: The State layer applies everywhere

Wherever the building is, the contractor must be licensed by the Texas State Fire Marshal's Office (SFMO / TDI), and the State's tag rules require notifying the local AHJ when a yellow or red tag is attached. See What yellow and red tags mean and How to verify a Texas fire contractor license.

Keeping both kinds of building straight on FireMarket

If you manage buildings on both sides of the city line, FireMarket's Harris County ITM compliance tracker keeps one row per property with the system type, last ITM date, any open yellow or red tag and, for TCE-tracked buildings, the TCE premise ID. Each bid shows the contractor's TX SFMO/TDI license class and a Verified or Failed/expired badge, checked daily at bid. You invite contractors from your list or share a private job link; it is not a public RFQ.
