Augusta-Richmond County's Comprehensive Zoning Ordinance does not define a distinct ADU category, but accessory buildings are permitted subject to size, height, setback, and use restrictions. Separate dwelling units typically require zoning approval and full building permits under the Georgia State Minimum Standard Codes.
Augusta operates under the Comprehensive Zoning Ordinance of Augusta, Georgia (Augusta-Richmond consolidated city-county government since 1996). The zoning ordinance treats secondary residential structures as accessory buildings, which are defined as subordinate structures generally limited to one story and not more than 18 feet in height, and which cannot exceed the height of the principal dwelling as viewed from the street. The ordinance specifically states that an accessory building is not a residential structure and cannot be occupied as such, and may not have a separate electrical service from the principal dwelling. Property owners seeking to build a true accessory dwelling unit (with kitchen, bathroom, and sleeping quarters) generally need to consult the Augusta Planning & Development Department (1803 Marvin Griffin Rd) to determine whether the use is permitted in their specific zoning district or whether a special exception is required. All construction must comply with the Georgia State Minimum Standard Codes (O.C.G.A. 8-2-20), which adopt the International Residential Code. Building permits are issued through Augusta's License & Inspection Department.
Constructing or occupying an accessory building as a separate dwelling without zoning approval and a building permit can result in stop-work orders, daily civil penalties, and required removal or conversion. Adding a separate electrical service to an accessory building is a direct ordinance violation.
