Building Energy Code

June 18, 2023


Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

Georgia's Department of Community Affairs periodically reviews, amends and/or updates the state minimum standard codes. Georgia has "mandatory" and "permissive" codes. Georgia State Energy Code for Buildings (International Energy Conservation Code) is a mandatory code and requires any structure built in Georgia to comply with these codes, whether or not the local government chooses to locally enforce them.

In July 2009, the Georgia State Codes Advisory Committee created a task force to review options for a green building standard. The committee adopted the National Green Building Standard with Georgia-specific Amendments as a voluntary optional code effective January 1, 2011.

Effective January 1, 2020, Georgia requires all commercial and residential buildings to meet 2015 IECC requirements with state specific amendments.
