Georgia operates under a statewide mandatory adoption model administered by the Department of Community Affairs (DCA). The State Codes Advisory Committee (SCAC) recommends code adoptions to the DCA Board. Current codes effective January 1, 2025 include IBC 2024, IRC 2024, IMC 2024, IPC 2024, IFGC 2024, NEC 2023, and ISPSC 2024 with Georgia amendments. Energy code is IECC 2015 with 2020, 2022, and 2023 Georgia amendments. New 2024 I-Codes with Georgia amendments become effective January 1, 2026. Georgia has three climate zones: Zone 2A (35 warm-humid southern counties), Zone 3A (majority of state), and Zone 4A (22 northern mountain counties). Wind Zone 2 (100 mph) applies to 6 coastal counties. Coastal High Hazard Areas (V zones) exist on barrier islands requiring pile foundations. No statewide residential sprinkler requirement. Local jurisdictions may adopt permissive codes (IPMC 2018, IEBC 2018, NGBS 2008) at their discretion. Atlanta has separate amendments. State Fire Marshal administers IFC and Life Safety Code (NFPA 101). Contact: DCA Office of Construction Codes (404) 679-3118, ib@dca.ga.gov.

Critical regulations for Georgia restoration work
Georgia adopted the 2024 IRC and IBC statewide as minimum codes. Local jurisdictions may adopt MORE restrictive requirements but cannot be LESS restrictive than state minimums.
Important: Georgia has adopted statewide mandatory minimum codes through the Department of Community Affairs (DCA). The state currently uses the 2024 IRC (with Georgia amendments) for residential construction. Local jurisdictions must enforce the state minimum codes but may adopt more restrictive local amendments. The DCA is the state agency responsible for code adoption and maintains the list of Georgia amendments. All 159 counties are required to enforce the state minimum codes, though enforcement capacity varies significantly between urban and rural jurisdictions. Building permits are required statewide for most construction work.
Georgia prohibits Assignment of Benefits (AOB) for property insurance. Contractors cannot negotiate directly with insurers on behalf of homeowners.
Important: Georgia Code §33-24-61.1 prohibits assignment of benefits for residential property insurance claims. Contractors cannot take assignment of insurance proceeds or negotiate claims on behalf of policyholders. This means contractors must bill homeowners directly, and homeowners pay from insurance proceeds. Contractors who act as public adjusters without a license (advising on claims, negotiating settlements) violate GA Insurance Code §33-23-1. Georgia actively enforces these provisions — multiple contractors have been prosecuted for UPPA violations since 2020.
Georgia allows municipalities to exempt ordinary repairs (re-roofing, siding, etc.) from permits if no structural changes are involved.
Important: Under Georgia's statewide mandatory codes (IRC 2018 as adopted), municipalities MAY exempt ordinary residential repairs from permit requirements. O.C.G.A. §8-2-26 defines ordinary repairs as maintenance work that does not alter structural components, reduce fire resistance, or change egress. Many GA counties exempt like-for-like re-roofing from permits (e.g., Gwinnett, Cobb, DeKalb in some cases). However, City of Atlanta, Savannah, and Augusta generally require permits for all roofing work. If work involves structural repair (deck boards, rafters, trusses), a permit is always required regardless of exemptions.
