The City’s rule
Detached garage permits in Fort Worth: what the City requires
Fort Worth requires a building permit for every detached garage. There’s no size small enough to skip it. The City’s zoning ordinance then sets the garage’s limits: how big it can be, how tall, where it sits on your lot and how many you can have.
“All detached garages require building permits.”
“All detached garages require a building permit. There are additional specific zoning requirements associated with the location and height, depending on if they have livable space.”
A carport takes one too. In the City’s words, “All carports, including fabric carports, require building permits.”
Replacing an old garage? Taking it down takes a razing permit of its own.

The garage’s own rules
How big and how tall a detached garage can be in Fort Worth
Fort Worth’s zoning ordinance sets rules for every building behind the house, and a few just for garages. Here is each one, in plain words.
-
How big
§5.300(c)§5.301(a)(3)
§5.300(c)§5.301(a)(3)
No more square feet than the house. And every roof on your lot, the garage’s included, counts toward your district’s lot coverage limit.
-
How tall
§5.301(b)(2)
§5.301(b)(2)
One story, and no taller than the house. It can have an attic or loft, as long as that space isn’t heated or air-conditioned.
-
Where it sits
§5.300(f)
§5.300(f)
Not in the front yard. It keeps the house’s side and rear setbacks, and in some districts a garage behind the house can sit closer. Setbacks by zoning district
-
How many
§5.301(b)(2)
§5.301(b)(2)
On a lot under half an acre, one garage and one carport per house. A second garage has to be part of the house, with the same roofline, and share its driveway. On half an acre or more, Article 5.301 allows a second, but another section of the ordinance says one; ask the City’s zoning desk before you plan it.
-
Power and water
§5.300(b)
§5.300(b)
Its electricity, water and gas come from the house’s meters, not meters of its own. The wiring and plumbing each take their own trade permit.
-
What makes it a garage
§5.300(a)
§5.300(a)
A door taller than six feet. With a door six feet or shorter, the ordinance calls it a private workshop.
-
A garage doesn’t count toward the City’s limit on sheds.
Fort Worth caps the total square feet of non-habitable accessory buildings by lot size, 200 on a 5,000- to 9,999-square-foot lot, and leaves a private garage out of that total.

Living space
If you want living space above your garage
Then the rules change. The City writes separate zoning rules for an accessory building with living space, and the brochure above says the location and height rules depend on it. If you want living space above or beside it, that’s a garage apartment, and we design, draw and build those.
On a garage apartment we build
Living space goes over the top, or beside it, and the cars stay where they are.
Who pulls it
Who pulls a detached garage permit in Fort Worth, and what the City inspects
The building permit goes to a registered building contractor, or to you, if the house is your homestead. Who qualifies for a homestead permit
A new garage is an accessory structure, and the City asks for a certified copy of your lot’s plat and a site plan with the application. What goes in the drawings
Wiring and plumbing in the garage are permits of their own. In the City’s words:
“Aside from your building permit, you still must obtain all trade permits that are needed separately and schedule inspections as required for each permit type.”
The City’s sequence for new construction; which steps your garage reaches depends on what’s in it.
-
Before work starts. The City’s stakeout inspection (105) checks that the work sits in the right place on your lot.
-
Before it’s covered. The foundation (115) is inspected before concrete is poured, and framing (110) once the rough-ins are approved. The City says permitted work “must remain accessible and exposed for inspection purposes until approved.”
-
The finals. Each trade permit’s final, then the building final (100).
If an inspector needs finished work opened up, the City says the cost is yours: “Neither the Building Official nor the jurisdiction shall be liable for expense entailed in the removal or replacement of any material required to allow inspection.”
