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.

The 2009 IECC is in effect for all residential and commercial buildings, Idaho schools and Idaho jurisdictions that adopt and enforce building codes unless a local code exists that is more stringent. Updated codes are adopted every three years by the Idaho Legislature as they are revised by the International Code Council. The most recent code was approved on June 8, 2010 and took effect January 1, 2011.

Enforcement of building and energy codes is handled by local building code adopters. Energy codes for state facilities and modular prefabricated buildings are enforced by the Idaho Division of Building Safety.
