Building Energy Code
Quick Summary
Oklahoma's building energy codes set minimum efficiency standards for new construction and major renovations in your area, ensuring homes are built to reduce energy consumption and lower utility costs. These codes, based on the 2018 IRC for residential buildings, become requirements when you build or significantly upgrade—your contractor must comply with these standards, and building permits enforce them.

Program Summary
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. In 2009 S.B. 1182 created the Oklahoma Uniform Building Code Commission. The 11-member Commission was given the power to conduct rulemaking processes to adopt new building codes. The codes adopted by the Commission must be approved by the Legislature before they can take effect. If the Legislature fails to act on the recommended code, it will take effect by default. The Commission recommended a residential code based on the 2009 IRC with Oklahoma amendments in March 2011, and it took effect July 2011. The Commission recommended a commercial code based on the 2009 IECC with Oklahoma amendments which took effect in November 2012. Local governments would be allowed to adopt "higher" standards than those recommended by the Commission.
