In unincorporated Tarrant County — the 3rd most populous county in Texas — building permits for commercial and multi-family structures are handled by the Tarrant County Fire Marshal's Office. Most of the county's population lives in incorporated cities (Fort Worth, Arlington, etc.) that handle their own permitting.
This guide covers permit requirements for unincorporated Tarrant County areas, the Fire Marshal's role, and the distinction between city and county jurisdiction.
Most of Tarrant County is within incorporated cities. Fort Worth, Arlington, and other cities handle their own permitting. Tarrant County's permitting authority in unincorporated areas is limited under Texas law to commercial, multi-family, and public-accessible buildings. Single-family residential in unincorporated areas may not require a county building permit — verify with the Fire Marshal's Office.
What requires a building permit in Tarrant County?
In unincorporated Tarrant County, the Fire Marshal's Office requires permits for:
Permit required
- New commercial and public-accessible construction
- Multi-family residential buildings
- Commercial alterations and tenant improvements
- Fire protection system installations
- Commercial demolition
- Structures used for public assembly
Typically exempt
- Single-family residential (limited county authority)
- Interior cosmetic work
- Agricultural buildings in certain cases
- Minor residential repairs
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. Note that exemption from a building permit does not exempt a project from zoning requirements — confirm edge cases with the building department.

Tarrant County trade permits
State trade licenses apply. TDLR and TSBPE licenses required for licensed work.
Electrical permits
TDLR-licensed electrician required for electrical work.
Plumbing permits
TSBPE-licensed plumber required for plumbing work.
Mechanical (HVAC) permits
TDLR-licensed mechanical contractor required for HVAC work.
Miscellaneous & specialty
Residential construction in unincorporated areas has limited county oversight. Most residents should contact their incorporated city for permitting.
Verify your contractor's license. Texas licenses electricians (TDLR), plumbers (TSBPE), and HVAC/mechanical contractors (TDLR) at the state level — contractors must register with the local municipality before pulling permits. Texas does not issue a statewide general-contractor license. Projects over $50,000 require a TDLR project number and accessibility review. The property owner is responsible for ensuring a permit is obtained. Verify trade licensure at tdlr.texas.gov and tsbpe.texas.gov.
