Where to apply

Primary ADU permit applications are handled by the City of Atlanta Office of Buildings.

For zoning confirmation, setback exceptions, or use verification, consult the Department of City Planning and the Zoning Division.

  • Check zoning designation and ADU allowances on your parcel before applying.
  • Budget for plan review fees and permit fees; amounts vary by scope and are listed with each permit type.
  • Contact the Office of Buildings early for pre-application guidance.
Start with a zoning confirmation letter if your lot has conditional or overlay zoning.

The Office of Buildings publishes permit application forms, submittal checklists, and electronic submission instructions on its permits page.
