ADU rules in Mesquite, TX — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Mesquite does not allow standalone accessory dwelling units in most single-family zones. Garage apartments and guest quarters may be allowed with restrictions and SUP.
Mesquite zoning generally does not permit accessory dwelling units (ADUs) as a by-right use in single-family residential districts (SF-7, SF-9, SF-12). The City's zoning code defines a dwelling unit as containing complete kitchen, bath, and sleeping facilities, and only one principal dwelling is allowed per single-family lot. Limited exceptions exist for live-in domestic worker quarters and for guest houses without full kitchens (no stove or full-size range). A garage apartment or detached guest suite with cooking facilities typically requires a Specific Use Permit (SUP) approved by the Planning & Zoning Commission and City Council, plus rezoning if not in a district that allows two-family use. Short-term rental of an accessory unit is separately regulated. Some larger lots in agricultural or estate zones may allow a second dwelling. Always verify your specific zoning district and lot size with the Planning Division before designing or building any second living space — converting a garage or shed into rentable living quarters without approval is a code violation.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Mesquite code enforcement directly for current fines, enforcement procedures, and hearing options.
