H.B. 65 changes 15A-2-103(1)(h) to the 2024 IECC from 2021 effective Jul 1, 2026, but DOE still lists residential as 2021 IECC (citing H.B. 518 of 2024) and ICC says residential IECC follows the IRC cycle (IRC stays 2021).
How Utah adopts the IECC residential
The Legislature names the IECC edition in 15A-2-103 and amends residential energy text through the IRC chapter amendments by bill. ICC’s page says residential IECC is reviewed every other cycle with the IRC.
Cycle. Every other ICC cycle for residential, per ICC’s state page.
