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.

These codes are mandatory statewide, meaning they apply to all construction regardless of whether they are locally enforced.
