ADU rules in Clayton County, GA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Clayton County allows accessory dwellings (guest houses, in-law suites) only as a conditional use, and only in the AG, ER, and RS-180 zoning districts. No more than one accessory dwelling is permitted per residential lot, inside or freestanding.
Under the Clayton County Zoning Ordinance (Sec. AS-05), an accessory dwelling may sit within the principal home or as a freestanding unit, but only in the AG, ER, and RS-180 districts and only by conditional-use approval. An interior accessory dwelling may not have its only entrance be a separate exterior door and requires one added parking space. Freestanding units must be in the rear yard, meet Article 3 setbacks, sit on a lot of at least 12,000 square feet, and provide extra parking. Municipalities like Jonesboro and Forest Park set their own rules for property inside city limits.
Building or occupying an accessory dwelling without conditional-use approval is a zoning violation cited by Code Enforcement (678-610-4755), subject to fines and abatement.
