In June 2009, the Oklahoma Legislature passed a bill creating the Oklahoma Uniform Building Code Commission that would be charged to review and recommend building codes (including energy codes) for residential and commercial construction for adoption. Under the revised Oklahoma Administrative Code, Title 748, the codes and standards recommended by the Commission would go before the Oklahoma Legislature. Should the Legislature not act to disapprove the recommendations, they will be submitted to the Secretary of State (SOS) for filing. Local governments would be allowed to adopt "higher" standards than those recommended by the Commission.
Beginning in October 2010, the Commission held several meetings discussing code change proposals for the 2009 editions of the ICC codes - including the IRC - through March 2011. On March 31, the Commission formally recommended a residential code based on the 2009 IRC with Oklahoma amendments. This recommendation was approved by Gov. Mary Fallin on May 10, 2011. The Legislature chose not to disapprove the rule, leading to the official adoption of the code on May 27. The statute was printed in the state register on July 1, becoming effective July 15, 2011.
The OUBCC has made modifications to IRC Chapter 11, most notably removing the requirement of programmable thermostats, allowing visual inspections for duct sealing, and making the placement of energy efficiency certificates on a home's electrical panel voluntary.
The OUBCC has submitted its proposed changes to the 2009 IBC and other I-Code editions to the Oklahoma Legislature for approval, tentatively slated to become effective in summer 2012. The OUBCC technical committees will review the 2009 IECC in the spring, summer, and fall of 2012.
