A Utah Uniform Building Standards Act was passed in 1953. In January 1976 a bill was passed that provided for the adoption of an energy conservation code for state buildings, suggested voluntary compliance by the state's political subdivisions, and recommended voluntary compliance by the state's building industry. In March 1977 legislation was passed requiring the Building Board to promulgate an energy conservation code and providing political subdivisions and the State Board of Education authority to adopt their own code or a modified version of the state code. Effective January 1978, a code based on the Model Code for Energy Conservation (MCEC) went into effect.
On January 1, 2006, Utah passed an update to the Utah Uniform Building Standard Act. The change went into effect on January 1, 2007, making the 2006 IECC mandatory for all residential and commercial buildings.
After the passage of the State Construction Code Adoption Act in early 2010, the Utah Legislature updated the Utah State Construction Code to reference the 2009 ICC codes series, including the 2009 IECC, beginning July 1, 2010. The residential provisions of the Utah State Construction Code are based on the 2009 IRC with Utah amendments, but the energy efficiency section (Chapter 11) of the 2009 IRC has been replaced with Chapter 11 of the 2006 IRC and Chapter 4 of the 2006 IECC (see Section 202-20).
On October 20, 2010, the Utah Senate Business and Labor Interim Committee chose not to follow the September 8, 2010 recommendation of the Utah Uniform Building Code Commission to adopt a modified version of the 2009 IECC for new homes and major residential renovations, keeping Utah’s energy conservation code for one- and two-family dwellings at the 2006 IECC.
On January 12, 2012, legislation (HB 262) was introduced in the Utah Legislature that would adopt the residential portions of the 2009 IECC. Though the bill was approved by the House Rules Committee in February, it was tabled by the House Political Subdivisions Committee on February 29, 2012, indefinitely postponing action during the general session.
Similar committees declined to take up similar update legislation in the February 2011 general session or the October 2011 interim session. Several local media outlets have highlighted the significant benefits of updating the energy code for Utah’s citizens.
