Permit overview and when you need one

An ADU usually requires a zoning review and a building permit when it involves new construction, structural alterations, plumbing, electrical or adding separate living facilities. Owners should confirm lot coverage, setbacks, parking, occupancy limits and utilities with Fort Worth planning and development before applying.

Step-by-step permit process

  • Pre-application: verify zoning, allowed ADU types and any overlay or historic-district rules with Planning/Development.
  • Prepare plans: site plan, floor plan, elevations and utility drawings stamped or prepared per city checklist.
  • Submit permit application and plans to Development Services via the official permits portal or in-person counter. Permits & Applications[2]
