The State Construction and Fire Codes Act (Title 15A) governs how building codes are adopted in Utah. For each update of a “nationally recognized construction code” The Uniform Building Code Commission has two years to prepare a report for the Utah State Legislature stating recommending updates and modifications and compiles costs and benefits for each recommended change. The Legislature’s Business and Labor Interim Committee reviews the report and files appropriate legislation for the next legislative session. For the IRC and residential portions of the IECC, this process occurs every other cycle. Political subdivisions may not enforce a rule or requirements that are more restrictive than the state construction code. Membership to The Uniform Building Code Commission and Utah State Fire Prevention Board are approved by the State Legislature.
