Applicability (statewide, local, limited): STATEWIDE

For the past several years, Utah State Statute 58-56-4 required statewide adoption of a building code, residential code, plumbing code, mechanical code, and fuel gas code promulgated by a nationally recognized code authority. The 2009 passage of SB211 moved the adoption authority to the state legislature. The Uniform Building Code Commission is now required to make adoption recommendations to the interim Senate Business and Labor Committee.
