Lehi, Utah has adopted: 2024 International Building Code (IBC) — Utah Code § 15A-2-103(1)(a); effective 2026-07-01, superseded the 2021 edition. NOTE (verified 2026-07-16): Lehi's own Building and Inspections page still lists 'Current Codes: 2021 I Codes' — the city's page has not been updated to reflect the 2024 editions that took effect statewide on 2026-07-01.; 2021 International Residential Code (IRC) — Utah Code § 15A-2-103(1)(b); unchanged by the 7/1/2026 code cycle; 2024 International Plumbing Code (IPC) — Utah Code § 15A-2-103(1)(d); effective 2026-07-01, superseded the 2021 edition; 2024 International Mechanical Code (IMC) — Utah Code § 15A-2-103(1)(e); effective 2026-07-01, superseded the 2021 edition; 2024 International Fuel Gas Code (IFGC) — Utah Code § 15A-2-103(1)(f); effective 2026-07-01, superseded the 2021 edition; 2023 National Electrical Code (NEC) — Utah Code § 15A-2-103(1)(g); unchanged by the 7/1/2026 code cycle. NOTE (verified 2026-07-16): Lehi's own Building and Inspections page lists '2020 NEC' — this is stale independent of the 7/1/2026 code cycle; the 2023 NEC has governed statewide since its own adoption (predating this fix and not caused by it).; 2024 International Energy Conservation Code (IECC) — Utah Code § 15A-2-103(1)(h); effective 2026-07-01, superseded the 2021 edition; 2024 International Existing Building Code (IEBC) — Utah Code § 15A-2-103(1)(i); effective 2026-07-01, superseded the 2021 edition; 2024 International Swimming Pool and Spa Code (ISPSC), residential provisions — Utah Code § 15A-2-103(1)(n); effective 2026-07-01, superseded the 2021 edition; ICC/ANSI A117.1-2017 (Accessible and Usable Buildings and Facilities) — Lehi City Building and Inspections page; NOTE (verified 2026-07-16): The 2024 editions of IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC took effect 2026-07-01 per Utah Code § 15A-2-103, superseding the 2021 editions that governed through 2026-06-30. The 2021 IRC and 2023 NEC were NOT changed by this cycle. Confirmed directly against the version of § 15A-2-103 effective 7/1/2026 (superseded 1/1/2027) at le.utah.gov. Lehi's own page (lehi-ut.gov/departments/building-and-inspections/) was checked live on 2026-07-16 and still reads 'Current Codes: 2021 I Codes' / '2020 NEC' — it reflects neither the 2024 code cycle nor the separately longer-standing 2023 NEC.. Local amendments apply — see the Lehi overview page for the full list.
