ADU rules in Dunwoody, GA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
ADUs in Dunwoody are regulated by the Zoning Ordinance (Ch. 27). Georgia has no statewide ADU mandate; Dunwoody determines eligibility by parcel zoning. Contact Planning and Zoning (678-382-6800) to confirm whether an ADU is permitted on a specific property and what standards apply.
Dunwoody's Zoning Ordinance (Chapter 27) governs accessory dwelling units. Chapter 27, §4-9 addresses buildings on single-family and duplex lots, and §4-1 covers accessory buildings, structures, and uses. Because ADU eligibility depends on the specific zoning district, lot size, and overlay regulations, property owners should contact the Planning Division (678-382-6800) for a pre-application review before designing or budgeting for an ADU project.
Unpermitted ADU: $500 to $2,000. May require demolition or retroactive permitting. Zoning violation: $250/day.
