How Utah adopts the IBC
The Legislature names the edition in 15A-2-103 and amends the Chapter 3 Utah amendments by bill. After each new model code edition the Uniform Building Code Commission has two years to report to the Legislature; the Business and Labor Interim Committee then drafts legislation (per ICC’s Utah page).
Cycle. Follows the ICC triennial cycle with a lag; 2021 IBC replaced by 2024 IBC effective Jul 1, 2026.
Laws, rulings, and other actions
- LegislationH.B. 41 Construction and Fire Codes Amendments2026 General Session
Moves the wildland-urban interface code to the 2024 edition and amends 15A-2-103 effective Jan 1, 2027; its text of that section still shows 2021 IBC and IECC, which needs reconciling with H.B. 65.
Passed; mostly effective Jan 1, 2027, two sections May 6, 2026
