ADU rules in Duluth, GA — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Accessory dwelling units in Duluth are regulated through the Unified Development Code. Accessory apartments may be permitted in certain residential zones with zoning approval; detached ADUs face stricter review.
Georgia has no statewide ADU preemption, so Duluth's zoning controls. The UDC may permit accessory apartments (internal ADUs within an existing single-family home) in R-100 and R-75 zones with owner-occupancy requirements and size limits (typically 25-50% of primary dwelling). Detached ADUs in residential zones typically require a Special Use Permit or variance. Short-term rental of ADUs is restricted under separate STR rules.
Unpermitted ADUs require removal or permit compliance; occupancy may be prohibited until legalized.
