NOTE (county page live-checked 2026-07-16): the Cache County Building Code Information page lists 2024 IECC in its main statewide-codes list but separately carries a 'Residential Code: 2021 IRC and the 2021 IECC' line for dwellings up to a duplex — that residential IECC carve-out lags the statute, which adopts a single 2024 IECC edition with no residential/commercial split; the statewide 2024 IECC governs.; 2024 International Existing Building Code (IEBC) — Utah Code § 15A-2-103(1)(i); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026); 2024 International Swimming Pool and Spa Code (ISPSC), residential provisions — Utah Code § 15A-2-103(1)(n); current edition as of July 1, 2026 (2021 edition governed through June 30, 2026); 2023 National Electrical Code (NEC) — Utah Code § 15A-2-103(1)(g); statewide in force, unchanged by the July 1, 2026 revision. NOTE: The Cache County Building Code Information page (last seen 2026-06-30) still lists '2020 NEC' — that page is not updated; the statewide 2023 NEC is the legally in-force edition.; NOTE (verified 2026-07-16 against the live Utah Code § 15A-2-103 text, version headed 'Effective 7/1/2026 / Superseded 1/1/2027'): the 2024 editions of IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC listed above took effect July 1, 2026, replacing the 2021 editions; IRC (2021) and NEC (2023) did not change. The 1/1/2027 version of the statute carries identical editions, so no further flip is expected then. This file previously forecast this change but still led with the 2021 editions as current — corrected on this date..
