ADU Design in Georgia: what governs your project

Georgia has no statewide ADU statute; rules are set by cities and counties. Atlanta has adopted some of the state's more ADU-friendly provisions, while many smaller jurisdictions restrict or prohibit accessory units.

Energy code

Permitting is local, with plan review for setbacks, lot coverage, and building code compliance. Impact and tap fees, owner-occupancy rules, and size caps vary by jurisdiction.

Permitting & plan check

Building permits and plan review are handled by city and county building departments under the statewide Georgia State Minimum Standard Codes. Metro Atlanta jurisdictions run electronic review with published checklists; coastal and smaller jurisdictions may have additional local amendments for wind, flood, and marshland protection.

Good to know

• Georgia's red clay soils are highly erodible, which is why the state is known for strict erosion and sediment control enforcement on construction sites.
• The Port of Savannah is one of the busiest container ports on the US East Coast, driving sustained industrial and logistics construction in the coastal region.
• Atlanta's rapid growth has made the metro area one of the most active commercial construction markets in the Southeast for decades.
