Dallas has a more complex ADU zoning landscape than most DFW cities, but there is real opportunity for homeowners in the right neighborhoods. Dallas uses overlay districts (ADUO — Accessory Dwelling Unit Overlay) to permit ADU construction by right in certain areas. Outside of overlay zones, homeowners can pursue a Board of Adjustment special exception. We research your specific address before any design work begins.
ADU and Garage Apartment Zoning in Dallas
Dallas ADU zoning is neighborhood-specific. In areas covered by the ADUO overlay, ADU construction is permitted by right — no special exception needed. Outside the overlay, a Board of Adjustment exception is typically required. Key requirements across Dallas: separate entrance required, ADU must comply with height and setback rules of the base zoning district, parking replacement may be required. Dallas permit fees vary by project type and size. Contact Dallas Development Services at (214) 948-4480 for address-specific guidance.
