Plumbing Codes and Legislation in Georgia
In Georgia, plumbing standards are governed by the state's mandatory construction codes. As of January 1, 2026, the state has adopted the 2024 International Plumbing Code (IPC) as the foundation for its plumbing requirements, supplemented by specific Georgia State Amendments. For one- and two-family dwellings and townhouses not exceeding three stories in height, the 2024 International Residential Code (IRC) with Georgia Amendments also applies to plumbing installations.
Primary State Agency
The Georgia Department of Community Affairs (DCA) is the primary state agency responsible for the adoption and maintenance of the Georgia State Minimum Standard Codes. Under the authority granted by O.C.G.A. § 8-2-20 through § 8-2-26, the DCA facilitates the adoption process, which includes review by the State Codes Advisory Committee and final approval by the Board of Community Affairs. These codes are mandatory statewide, meaning they apply to all construction regardless of whether they are locally enforced.
