ADU rules in Cedar Hill, TX — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Cedar Hill generally restricts accessory dwelling units (ADUs) in single-family zones. Guest quarters without a kitchen may be allowed; full second dwellings require specific zoning approval.
Unlike California or Oregon, Texas does not have a statewide ADU mandate, leaving ADU regulation to local jurisdictions. Cedar Hill's zoning ordinance traditionally does not allow second full dwelling units on single-family lots; only one principal residence is permitted per lot in most residential districts. Guest quarters or accessory living spaces (without a kitchen) for family members may be allowed as part of an accessory structure or attached to the main home. Renting out an ADU as a separate dwelling is generally prohibited. Check current zoning ordinance with Planning (972-291-5100) since cities periodically update ADU rules. Specific Use Permits or Planned Development zoning may permit limited ADUs case-by-case.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Cedar Hill code enforcement directly for current fines, enforcement procedures, and hearing options.
