H.B. 313 (2025) changed the NEC from 2020 to 2023 effective July 1, 2025; NFPA’s table says 1/1/2025, which does not match the enrolled bill. The 2026 H.B. 65 still lists the 2023 NEC.
Exceptions
- Political subdivisions may not enforce requirements more restrictive than the state construction code (per ICC state page)
How Utah adopts the NEC
The Legislature names each edition in Utah Code 15A-2-103 and changes it by passing a bill, normally a bill effective July 1. The Uniform Building Code Commission reports on each new model code and the Business and Labor Interim Committee drafts legislation for the next general session (as described on ICC’s Utah page). No agency rule alone updates the edition.
Cycle. Irregular, bill by bill; the NEC moved 2020 to 2023 in 2025. Residential IRC and residential IECC are reviewed every other cycle per ICC’s state page.
