Atlanta Deck Permits: What Actually Gets Checked, County by County

Yes — all structural decks in Metro Atlanta require a building permit. What trips people up is that requirements vary by jurisdiction, and Metro Atlanta covers four separate permitting offices depending on where your home sits. Here's the breakdown, and what to expect from each.

City of Atlanta (Buckhead, Midtown & Intown)

Homes inside the City of Atlanta — including Buckhead and Midtown — fall under Atlanta's Office of Buildings. Permits typically require stamped structural drawings and a site plan, and approval timelines can run 5-15 business days depending on current volume.

Fulton County (Sandy Springs, Alpharetta & Roswell)

Fulton County covers Roswell, Alpharetta, and Sandy Springs. Like the City of Atlanta, the county requires stamped structural drawings for anything attached to the house or elevated more than a step, plus a site plan showing setbacks.

Cobb County (Marietta, Smyrna & Kennesaw)

Cobb County covers Marietta, Smyrna, and Kennesaw. The permit process is broadly similar to Fulton's, though inspection scheduling and exact form requirements differ enough that using the wrong template can cost you a resubmission cycle.

DeKalb County (Decatur & Dunwoody)

DeKalb County oversees Decatur and Dunwoody. Older, established neighborhoods here sometimes trigger additional review if a new deck changes the footprint of a historic-adjacent property, which we check for during the estimate.

What Every Jurisdiction Has in Common

Regardless of county, permits typically require stamped structural drawings and a site plan, and most decks attached to a house or elevated more than a step or two need one. We handle every aspect of the permit process for you — from preparing the drawings to application submission to scheduling the final inspection — at no additional charge, in whichever jurisdiction your address falls under.

Avoid any contractor who offers to skip the permit to save money — it creates real legal liability that follows the homeowner, not the contractor, and it can stall a home sale years down the line.
