Unincorporated Uintah County, Utah has adopted: 2024 International Building Code (IBC), including Appendices C and J — current statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(a); supersedes the 2021 edition. Uintah County's own Building Code page (uintah.gov) still states '2021 International Building Codes Effective July 1, 2023' — the county page has not been updated for the 2024 statewide edition now in force; the statute governs.; 2021 International Residential Code (IRC) — REMAINS CURRENT; Utah Code § 15A-2-103(1)(b) did not change this edition in the 7/1/2026 statewide transition.; Appendix AQ of the 2021 IRC — statewide per Utah Code § 15A-2-103(1)(c); not itemized on Uintah County's own Building Code page, added here per statute.; 2024 International Plumbing Code (IPC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(d); supersedes the 2021 edition.; 2024 International Mechanical Code (IMC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(e); supersedes the 2021 edition.; 2024 International Fuel Gas Code (IFGC) — current statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(f); supersedes the 2021 edition.; 2024 International Energy Conservation Code (IECC), single unsplit statewide edition — current statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(h); supersedes the 2021 edition.; 2024 International Existing Building Code (IEBC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(i); this supersedes the 2021 edition. Uintah County's FAQ page ('Do I need a permit for my building? It's portable on a skid?' article) still cites 'Chapter 14 of the 2018 International Existing Building Code (IEBC)' and '2018 International Building Code (IBC)' / '2015 International Residential Code (IRC)' / 'IRC 2015 or IBC 2018' for relocated/moved structures — a substantial lag (2015/2018 editions vs. the current 2024/2021 statewide editions); the FAQ page's separate 'When are building permits required' article also still cites 'IBC 2015 & IRC 2015' verbatim. The statute governs; Uintah County's FAQ page has not been updated to reflect any statewide code cycle since at least 2015/2018.; Residential provisions of the 2024 International Swimming Pool and Spa Code (ISPSC) — current statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(n); supersedes the 2021 edition.; 2023 National Electrical Code (NEC) — REMAINS CURRENT; Utah Code § 15A-2-103(1)(g) did not change this edition in the 7/1/2026 statewide transition. Uintah County's Building Code Information page is UNCHANGED and still lists '2020 National Electrical Code (NEC) Effective July 1, 2021' — that page remains not updated; the statewide 2023 NEC is the legally in-force edition per the statute.; NOTE (2026-07-16 re-verification): Utah Code § 15A-2-103, version effective 7/1/2026 (superseded 1/1/2027), took effect 15 days before this re-verification — the flip anticipated by the prior 'Effective July 1, 2026' note has now occurred and is confirmed live. IBC/IPC/IMC/IFGC/IECC/IEBC/residential ISPSC are now 2024 statewide; IRC (2021) and NEC (2023) did NOT change. Uintah County's own Building Code page and FAQ page were both live-checked 2026-07-16 and remain unchanged/stale exactly as previously found (in the FAQ's case, considerably staler than previously documented — see the IEBC entry above) — the statute is cited directly as governing throughout, per the established recovery-avenue policy.. Local amendments apply — see the Unincorporated Uintah County overview page for the full list.
