Cobb County, GA Accessory Structures: Carport Rules (2026)

Cobb County Community Development requires a building permit for carport construction, whether freestanding, pre-fabricated kit, or attached to the primary structure. Carports classified as accessory structures under Cobb Zoning Ordinance Article V must meet setback requirements — typically 10 feet rear, 5 to 10 feet side depending on zoning district (R-20, R-15, R-12, etc.), and cannot extend into front setback unless meeting specific design standards. Maximum height generally 15 feet. Attached carports trigger additional review as building additions, including matching architectural style per neighborhood standards. Materials must meet wind loading (typically 115 mph design wind in Cobb) and snow loading minimums per Georgia-adopted IRC. Carport area counts toward maximum lot coverage percentage (varies by zoning but typically 30 to 40 percent). Pre-fabricated metal carport kits commonly seen along Cobb Parkway still require permitting despite being sold without mention of permitting requirements. HOA covenants in many Cobb subdivisions prohibit or restrict carports in favor of garages.
