Codes adopted

2021 International Residential Code (IRC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(b); unchanged by the July 1, 2026 statewide update. Millard County Building Inspection Department page (adopted codes list) also lists 2021 IRC — live-checked 2026-07-16, page unchanged since last check.2024 International Building Code (IBC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(a), effective since July 1, 2026, superseding the 2021 IBC. NOTE (2026-07-16, live-checked): the Millard County Building Inspection Department page still lists 2021 IBC — the county page is lagging the statewide statutory update by 15+ days; the statute is controlling.2024 International Plumbing Code (IPC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(d), effective since July 1, 2026, superseding the 2021 IPC. NOTE (2026-07-16, live-checked): the county page still lists 2021 IPC — page lag, statute controls.2024 International Mechanical Code (IMC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(e), effective since July 1, 2026, superseding the 2021 IMC. NOTE (2026-07-16, live-checked): the county page still lists 2021 IMC — page lag, statute controls.2023 National Electrical Code (NEC) per Utah Code § 15A-2-103(1)(g), statewide in force and NOT changed by the July 1, 2026 update — NOTE: this is a separate, pre-existing discrepancy: Millard County's own Building Inspection page lists 2020 NEC (live-checked again 2026-07-16, page still shows 2020 NEC, unrelated to the 2021→2024 code-edition transition affecting the other codes below). Contractors/homeowners should confirm current applicability with the Building Official as the county page lags the statewide amendment.2024 International Fuel Gas Code (IFGC) with State of Utah Amendments — per Utah Code § 15A-2-103(1)(f), effective since July 1, 2026, superseding the 2021 IFGC. NOTE (2026-07-16, live-checked): the county page still lists 2021 IFGC — page lag, statute controls.2024 International Energy Conservation Code (IECC), Residential & Commercial — per Utah Code § 15A-2-103(1)(h), effective since July 1, 2026, superseding the 2021 IECC. The statute adopts a single IECC edition with no residential/commercial split (this file's existing single combined line already reflects that — no split to collapse). NOTE (2026-07-16, live-checked): the county page still lists 2021 IECC — page lag, statute controls.2024 International Existing Building Code (IEBC) — per Utah Code § 15A-2-103(1)(i), effective since July 1, 2026. Not separately listed on the Millard County Building Inspection Department page (live-checked 2026-07-16, page has no IEBC entry at all) — added here because § 15A-2-103 adopts it statewide regardless of the county page's omission.2024 residential provisions of the International Swimming Pool and Spa Code (ISPSC) — per Utah Code § 15A-2-103(1)(n), effective since July 1, 2026. Not separately listed on the Millard County Building Inspection Department page (live-checked 2026-07-16, page has no ISPSC entry at all) — added here because § 15A-2-103 adopts it statewide regardless of the county page's omission.Utah Wildland Urban Interface CodeNOTE (updated 2026-07-16): The July 1, 2026 statewide code-edition transition (2024 IBC/IPC/IMC/IFGC/IECC replacing 2021 editions, per Utah Code § 15A-2-103 version effective 7/1/2026, superseded 1/1/2027) took effect 15 days ago; the next statute version's editions were diffed and confirmed identical, so this should not go stale again around 1/1/2027. 2021 IRC is unchanged by this transition. The International Fire Code is NOT adopted by § 15A-2-103 (it is addressed separately in Title 15A Chapter 5) and is not otherwise referenced in this file.
