Deck Construction Permits in Georgia
The only exception is a small freestanding platform 200 sq ft or smaller and no more than 30 inches above grade that is not attached to the house (IRC R105.2); any attached or elevated deck needs a permit.
The Building Code in Georgia
Georgia State Minimum Standard Codes, 2024 IRC/IBC with Georgia Amendments, effective January 1, 2026
The Georgia Department of Community Affairs (DCA) administers a mandatory statewide code, based on the 2024 International Building and Residential Codes with Georgia amendments effective January 1, 2026, that applies everywhere regardless of whether a local government maintains its own inspection department. Under the code, a deck needs a permit if it attaches to the house via a ledger connection, stands more than 30 inches above grade at any point within 36 inches of the edge, or exceeds the county's small structure exemption, commonly around 200 square feet for a detached, ground level platform. Georgia separately publishes its own Prescriptive Deck Details guide, a state specific supplement to the IRC providing standardized framing plans and connection details used by building departments statewide.
Quick Facts
Who Sets the Rules
Three separate triggers, any one is enough
Georgia's deck permit rule isn't a single number, attachment to the house, height above 30 inches, or exceeding the county's size exemption each independently require a permit, so a deck can trip the requirement on any one of these even while staying under the others.
A very recent code update
Georgia adopted the 2024 IRC and IBC with Georgia amendments effective January 1, 2026, making it one of the more current statewide codes covered in this research, only months old at the time of this writing.
A state supplement most states don't publish
Georgia's own Prescriptive Deck Details guide gives standardized framing plans and connection details specifically for deck construction, a state authored construction reference that building departments across Georgia's counties use directly, distinct from just adopting the IRC's own generic tables.
A real dollar threshold for licensed contractor work
Under GA Rule 553-3, any residential improvement project with combined labor and materials value over $2,500 must be performed by a licensee of the Georgia State Licensing Board, a genuinely low dollar threshold compared to many other states.
Coastal counties face real wind design differences
Design wind speeds range from about 115 mph inland to 130-140 mph along the coast, with six named counties, Chatham, Bryan, Liberty, McIntosh, Glynn, and Camden, in the higher wind zone, and Tybee Island, Jekyll Island, and St. Simons additionally falling inside a Wind Borne Debris Region under ASCE 7.
What people get wrong
The most common mistake is assuming a small, low deck automatically skips the permit. Attachment to the house alone triggers the requirement regardless of size or height, and a handful of rural Georgia counties have no inspection department to issue a permit at all, though the deck must still meet the state minimum code by law.
