Georgia HVAC Legislation, Codes, and Guidelines
Georgia HVAC Building Codes and Legislation
In Georgia, building construction standards, including those for HVAC systems, are governed by the Uniform Codes Act. The state adopts mandatory minimum standard codes that apply to all construction across the state, regardless of whether they are locally enforced. These codes consist of national model codes published by the International Code Council (ICC) or other standard-setting bodies, supplemented by specific Georgia amendments.
Adopted Codes (Effective January 1, 2026)
As of January 1, 2026, the State of Georgia has adopted the following mandatory codes relevant to HVAC design, installation, and energy efficiency:
- 2024 International Mechanical Code (IMC) with Georgia Amendments

Primary State Agency
The Georgia Department of Community Affairs (DCA) is the primary agency responsible for the adoption and maintenance of the state's minimum construction codes. The DCA facilitates the State Codes Advisory Committee (SCAC), which reviews new model codes and proposes amendments. Final adoption of these codes is approved by the Board of Community Affairs.
