Bathroom remodel permits in Fort Worth vs Dallas: what each city asks for
Fort Worth and Dallas sit thirty miles apart and both follow the residential code, but their permit rules for a bathroom remodel are worded differently, and a few details catch owners out.
By Russell Leach, Bathroom Remodeling Guides EditorUpdated October 20264 min read
In both Fort Worth and Dallas, a cosmetic bathroom update needs no permit, but moving or changing plumbing or electrical does. Fort Worth's rules are notably specific: rebuilding a shower pan needs a plumbing permit, replacing 16 square feet or more of drywall needs a building permit, and changing an exhaust fan needs a mechanical permit.
The short version
Both cities draw the same basic line. If you are replacing finishes and fixtures in the same places, such as new tile on a sound floor, a new vanity, a new faucet or toilet on the existing lines, you usually do not need a permit. If you are changing the plumbing, the wiring or the structure, you do.
Where they differ is in how specifically they spell out the edge cases, and Fort Worth spells out several that matter on almost every real bathroom remodel. Because permits come from the city, not the county, the rules that apply depend on which city the house is in, even in suburbs that straddle county lines.
What Fort Worth says
Fort Worth's residential permit guidance says cosmetic remodels, which it describes as floor or wall covering, cabinets, counter tops and similar work, and plumbing fixture replacement do not need a permit. Changing, installing, moving or repairing plumbing does, and the city names water heaters and shower pans specifically. Changing, moving or repairing electrical needs an electrical permit.
The city's homeowner guide adds two details that apply to most bathrooms. Replacing drywall that totals 16 square feet or more in any wall or ceiling needs a building permit, and changing or repairing exhaust fans needs a mechanical permit. A full bathroom remodel that opens the walls around a shower easily passes 16 square feet, and most remodels replace the fan.
- Shower pan rebuild: plumbing permit
- Moving any fixture: plumbing permit
- 16 sq ft or more of new drywall: building permit
- New or replaced exhaust fan: mechanical permit
- New circuits or moved outlets: electrical permit
What Dallas says
Dallas follows the 2021 residential code. Cosmetic bathroom work with no plumbing or electrical changes is exempt; moving or adding fixtures needs plumbing and building permits; adding a bathroom or removing walls needs a building permit, with engineered plans for a load-bearing wall. Electrical changes need an electrical permit, and Dallas bathroom permit fees typically run from about fifty to seven hundred dollars depending on scope.
In practice, a Dallas remodel that rebuilds the shower, moves a fixture or adds circuits for lighting or a heated floor is permitted work, and a refresh that swaps finishes in place is not.

Most remodels land in the same place in both cities: a full remodel with a new shower and updated wiring needs permits in either one. The differences matter most for mid-sized jobs, such as rebuilding a leaking shower without changing anything else, which Fort Worth explicitly treats as permitted plumbing work.
| Work | Fort Worth | Dallas |
|---|---|---|
| Cosmetic refresh, fixtures in place | No permit | No permit |
| Rebuild a shower pan | Plumbing permit (named) | Permit when plumbing changes |
| Move or add a fixture | Plumbing permit | Plumbing and building permits |
| Large drywall replacement | Building permit at 16 sq ft+ | Permit when walls change |
| Replace an exhaust fan | Mechanical permit | Permit when wiring changes |
| Add circuits or move outlets | Electrical permit | Electrical permit |
Inspections and timing
Permitted work is inspected before it is covered: rough plumbing and electrical with the walls open, a shower pan test where required, and a final inspection when the room is finished. A good contractor builds those inspections into the schedule rather than waiting on them, so the job does not stall with the walls open.
In both cities, the permit is pulled before demolition starts. Starting first and permitting later risks a stop-work order and having to open finished walls for inspection.
Who pulls the permit
On a contracted remodel, the contractor normally files the permits and schedules the inspections, and the permit cost appears in the written scope. If you are comparing quotes, check that each one includes the permits the work needs; a quote that leaves them out is not cheaper, it is incomplete. We file permits for our bathroom remodels in both cities, scheduled from our Dallas and Weatherford offices, and you can read more about local coverage on our Fort Worth page.
