Yes — you need a building permit for any accessory dwelling unit in Fort Worth, whether it is a detached ADU, an attached ADU, or a garage conversion. Fort Worth regulates ADUs as 'Accessory Uses on Residential Lots' under §5.301 of the Zoning Ordinance (Appendix A to the City Code). In one-family ('A' through 'AR') districts, an ADU is permitted as an accessory dwelling but cannot be operated as a separate, independent residence. ADUs must observe the side and rear setbacks of the underlying zoning district and may not exceed the height of the primary residence.

Fort Worth FAQ
Do I need a permit for an ADU in Fort Worth?
Yes. Fort Worth requires a building permit from Development Services for any accessory dwelling unit, including detached ADUs, attached ADUs, and garage conversions to living space. Plumbing, electrical, and mechanical permits are also required. Construction without permits violates Fort Worth Building Law and triggers stop-work orders and fines.
What is the difference between a detached ADU and an attached ADU in Fort Worth?
A detached ADU is a stand-alone accessory dwelling on the same lot as your primary home — for example, a backyard cottage. An attached ADU shares at least one wall with the main house, like a second-story apartment over an attached garage. Both are regulated under §5.301; detached ADUs are limited to one story plus an unheated loft and cannot exceed the height of the primary residence.
Can I rent my Fort Worth ADU to a separate tenant?
Not in one-family zoning districts (A-5, A-7.5, A-10, A-21, A-43, AR). §5.301 prohibits using an ADU as a separate independent residence in these districts. ADUs are allowed for household members, guests, or domestic staff. Two-family 'B' and multi-family districts under §4.707 allow separate dwelling units.
How big can my Fort Worth ADU be?
Fort Worth does not set a single square-footage cap, but the total rooftop area of all structures (primary home plus accessory buildings) may not exceed the district's maximum lot coverage. In one-family districts the ADU also cannot exceed the height of the primary residence.
How far does my Fort Worth ADU have to be from the property line?
ADUs must observe the side and rear setbacks of the underlying zoning district. For example, A-5 One-Family typically requires a 5-foot side and 5-foot rear setback for accessory buildings. Check your specific district under §4.701 et seq.
Do I need additional parking for my Fort Worth ADU?
Yes. Fort Worth generally requires one additional off-street parking space for a habitable accessory unit, on top of the two off-street spaces required for the primary single-family dwelling under §6.201.
North Richland Hills FAQ
Can I build a backyard apartment in NRH?
Generally no. A separate dwelling unit with its own kitchen requires a specific use permit or PD zoning and is rarely approved in standard residential districts.
Can I add a kitchenette to a pool house?
A wet bar or microwave is usually fine, but a full kitchen with a stove converts the structure into a dwelling unit and triggers zoning review.
