Millcreek's Building Services page previously referenced a 2020 NEC edition (recorded as of 2026-06-30); the 2023 NEC supersedes it statewide regardless of the page's wording; 2024 International Energy Conservation Code (IECC) — currently in effect statewide as of July 1, 2026, a single edition with no residential/commercial split under current law (Utah Code § 15A-2-103(1)(h)); Historical (superseded): prior to July 1, 2026, Millcreek's Building Services page cited a 2015 IECC edition for residential and a separate 2021 IECC edition for commercial — both are now superseded by the single 2024 IECC per § 15A-2-103(1)(h); re-checked live 2026-07-16 and Millcreek's page (millcreekut.gov/165/Building-Services, via its Building Department overview page and 'Adopted Construction Codes' resource) still displayed this superseded 2015/2021 split — city page lags the statute; 2024 International Existing Building Code (IEBC) — currently in effect as of July 1, 2026, superseding the 2021 IEBC that was in effect through June 30, 2026 (Utah Code § 15A-2-103(1)(i)); Residential provisions of the 2024 International Swimming Pool and Spa Code (ISPSC) — currently in effect as of July 1, 2026, superseding the 2021 ISPSC that was in effect through June 30, 2026 (Utah Code § 15A-2-103(1)(n)); 2006 International Wildland-Urban Interface Code (IWUIC) — millcreekut.gov/165/Building-Services; applies to Foothills/Canyons Overlay Zone properties; NOTE (updated 2026-07-16): the July 1, 2026 transition forecast in the prior version of this entry has now occurred — confirmed live against Utah Code § 15A-2-103, current version (effective 7/1/2026, superseded 1/1/2027), read at le.utah.gov/xcode/Title15A/Chapter2/15A-2-S103.html. Millcreek's own Building Department page (millcreekut.gov, live 2026-07-16) still displays a banner reading 'On July 1, 2026, the State of Utah will adopt all 2024 I-Codes with State Amendments. Any Commercial project submitted on or after July 1st will need to be designed to these standards' — forward-looking, present-tense-stale wording that also narrows the transition to Commercial projects only; the statute imposes no residential/commercial distinction for IBC/IPC/IMC/IFGC/IECC/IEBC/ISPSC, so this record treats the full 2024 edition set as governing for all project types as of 2026-07-16, and flags the city page as not yet updated to reflect that the date has passed. Local amendments apply — see the Millcreek overview page for the full list.
