A verified guide to Georgia deck permit rules: statewide code, fees, plans required, state-specific quirks, and how top cities handle applications.
Statewide Code
2024 International Residential Code with Georgia Amendments (effective January 1, 2026)
Frost Line
No statewide frost-line value is defined. The 2024 IRC with Georgia Amendments sets a minimum footing depth of 12 inches below undisturbed ground for deck piers. Piedmont and coastal Georgia average 5 inches of frost penetration; North Georgia mountain counties (Rabun, Union, Towns, Fannin, White) routinely require 18-24 inches, and local jurisdictions there may require deeper — always verify with the county.
Guard Rule
Per IRC R312.1.2 as adopted by Georgia, any deck walking surface more than 30 inches above the adjacent grade (measured 36 inches horizontally out from the edge) requires guards at least 36 inches tall. Openings in the guard must reject a 4-inch sphere. Stair guards may be 34-38 inches, measured from the stair nosing.
Typical Permit Cost
$50-$500+ for most residential decks. Atlanta charges $7.00 per $1,000 of valuation plus a $25 technology fee (minimum permit $150, with a separate $350 minimum for residential decks/balconies/porches). Cobb County charges $5.75 per $1,000 of construction cost with a $100 minimum. Marietta charges $5 per $1,000 plus a $50 base (minimum $50). Athens-Clarke County charges an $80 base plus $3 per $1,000 of valuation, with a plan-check fee equal to 50% of the permit (minimum $80).
Processing Time
Typically 3-15 business days. Atlanta: "a few business days to a couple of weeks" per the Office of Buildings, longer if plan review loops back. Athens-Clarke County issues most residential permits the next business day after a complete application. Coastal counties (Chatham, Glynn) usually require 2-4 weeks for engineered reviews of attached decks.
Georgia Department of Community Affairs (DCA)
Effective January 1, 2026, the Georgia DCA Board of Community Affairs adopted the 2024 IRC (with Georgia Amendments) as the state minimum standard code under O.C.G.A. § 8-2-23. The 2026 Georgia Amendments to the 2023 National Electrical Code also took effect the same day. Georgia is a state-minimum, locally-enforced system: the DCA publishes the floor, but every permit is issued and inspected by the city or county. Not all rural Georgia counties maintain an inspection department, so a handful of unincorporated areas still issue no building permits at all, though decks attached to residences must still meet the state minimum code by law.
Official sourceUltimate design wind speed (Vult) ranges from 115 mph inland (most of the state) to 130-140 mph along the Atlantic coast. The six coastal counties — Chatham, Bryan, Liberty, McIntosh, Glynn, and Camden — are in the higher-wind zone, and Tybee Island, Jekyll Island, and St. Simons fall inside Wind-Borne Debris Region per ASCE 7. Central Georgia sees moderate hail exposure. Seismic Design Category is A or B statewide. Termite protection (Category "Very Heavy" per IRC Figure R301.2(6)) applies across the entire state, which affects contact between deck ledgers and wood-framed walls.
Exempt from permit does not mean exempt from the code. Work still must comply with the edition in force at your address.
Georgia is one of the few states where the statewide code is mandatory (O.C.G.A. § 8-2-25) but enforcement is entirely local. A handful of rural counties have never created a building-inspection department, which means no permit exists to pull — but the deck still has to meet the state minimum code if a lawsuit or insurance claim ever tests it.
Under GA Rule 553-3, any residential improvement project with a combined labor-plus-materials value over $2,500 must be performed by a licensee of the Georgia State Licensing Board for Residential and General Contractors. Residential-Basic covers jobs up to $50,000, Residential-Light-Commercial covers up to $150,000, and General Contractor has no cap. Homeowners building on their own primary residence are exempt.
The six counties touching the Atlantic — Chatham, Bryan, Liberty, McIntosh, Glynn, and Camden — are in a 130-140 mph Vult wind zone and fall in the Wind-Borne Debris Region. Attached decks here almost always require engineered ledger connections, hurricane ties at every post-to-beam and beam-to-joist joint, and in some cases a Georgia-licensed engineer stamp.
All of Georgia is classified "Very Heavy" for subterranean termite probability per IRC Figure R301.2(6). Ledger attachment details must maintain clearance and flashing to prevent wood-to-masonry moisture paths, and pressure-treated lumber is required for any framing within 18 inches of exposed earth.
While the 2024 IRC with Georgia Amendments sets a 12-inch minimum footing depth statewide, mountain counties (Rabun, Union, Towns, Fannin, White, Lumpkin, Gilmer) routinely require 18-24 inches because of elevation-driven frost penetration. Always call the county before excavating.
$7.00 per $1,000 of valuation plus $25 technology fee; $150 minimum permit, $350 minimum for residential decks/balconies/porches; plan review equals the permit fee.
Repairs to a single-family structure valued under $10,000 are permit-exempt, but this does NOT apply to new decks — any new attached deck still requires a permit.
Permit portalFees set per the Savannah Development Services fee schedule; attached decks require submittal to the Development Services Department at 2 East Bay Street and are reviewed against the coastal 130-140 mph Vult wind zone.
Historic District properties route through the Historic Preservation Department for a Certificate of Appropriateness in addition to the building permit — this can add 4-8 weeks.
Permit portalPermit fees per the Augusta-Richmond Permit Fee Schedule; a permit is required any time materials exceed $500 or an inspection is required by the adopted construction code.
License & Inspection combines license verification with permit intake — a missing residential-contractor license number will stop the application at the counter.
Permit portalConsolidated Columbus-Muscogee Inspections & Code Enforcement handles residential deck permits; fees are valuation-based per the local schedule.
Permit portal$80 base permit fee plus $3 per $1,000 of project valuation; plan-check fee is 50% of the permit (minimum $80). Accepts cash, check, Visa, MasterCard, Amex, Discover, and Apple Pay.
Completed residential applications are typically issued the next business day.
Permit portalAny construction exceeding $2,500 requires a building permit; fees per the Macon-Bibb Permit Fee Schedule, processed through the Community Connect portal.
Permit portalCity of Marietta: $5 per $1,000 of construction cost plus a $50 base fee (minimum $50). Unincorporated Cobb County: $5.75 per $1,000 of construction cost (minimum $100); fee schedule updated per HB 461 effective July 1, 2024.
Addresses inside Marietta city limits pull from Marietta; unincorporated Cobb addresses pull from Cobb County — the two schedules are different.
Permit portalYes, in almost all cases. Under IRC R105.2 as adopted by Georgia, a deck is permit-exempt only if it is freestanding, under 200 square feet, no more than 30 inches above grade at any point, and does not serve a required exit door. Any deck attached to the house, or any deck with stairs serving an elevated level, needs a permit. Rules are enforced at the city or county level, so always confirm with your local building department.
The 2024 International Residential Code with Georgia Amendments, effective January 1, 2026, as adopted by the Georgia Department of Community Affairs under O.C.G.A. § 8-2-23. The 2026 Georgia Amendments to the 2023 NEC also took effect the same day.
If the combined labor-plus-materials value is more than $2,500, yes — Georgia law (GA Rule 553-3) requires a licensee of the State Licensing Board for Residential and General Contractors. Residential-Basic (up to $50K jobs) or Residential-Light-Commercial (up to $150K jobs) is typical for deck work. Homeowners building on their own primary residence are exempt from the license requirement, but still need the permit.
The Georgia-amended IRC sets a 12-inch minimum footing depth. In the North Georgia mountains (Rabun, Union, Towns, Fannin, White), counties frequently require 18-24 inches because of elevation-driven frost. Along the coast, depth is less about frost and more about reaching stable bearing soil and resisting uplift from 130-140 mph design winds.
If the deck is more than 30 inches above grade (measured 36 inches horizontally from the edge), IRC R312.1.2 as adopted by Georgia requires a guard at least 36 inches tall. Openings in the guard must reject a 4-inch sphere. Stair guards may be 34-38 inches, measured from the nosing of the tread.
Yes. In the six coastal counties — Chatham, Bryan, Liberty, McIntosh, Glynn, and Camden — the ultimate design wind speed is 130-140 mph and decks typically fall within the Wind-Borne Debris Region. Attached decks generally require engineered connectors for the ledger, post-to-beam, and post-to-footing, and some jurisdictions require a Georgia-licensed engineer stamp.
It varies by jurisdiction. Atlanta: $7 per $1,000 of valuation plus a $25 technology fee, with a $350 minimum for residential decks. Athens-Clarke: $80 plus $3 per $1,000, plus a 50% plan-check fee. Cobb County: $5.75 per $1,000 with a $100 minimum. City of Marietta: $5 per $1,000 plus a $50 base. Most residential deck permits land in the $50-$500 range.
Not really. Some rural Georgia counties do not operate a building-inspection department, so no permit is issued. But the state minimum code still applies under O.C.G.A. § 8-2-25 — which means your deck can still be called out in a lawsuit, a home-sale inspection, or a homeowners-insurance claim if it does not meet the adopted IRC. Build to code even when nobody is checking.
