South Ogden, Utah has adopted: GOVERNING LAW: Utah Code § 15A-2-103 (le.utah.gov/xcode/Title15A/Chapter2/15A-2-S103.html), version effective 7/1/2026 (amended by Ch. 47, 2026 General Session), sets the statewide-mandatory construction code suite (Utah Code § 15A-1-204 — binds every municipality; local amendments permitted, a different edition is not). South Ogden's official Building & Inspections FAQ page ('What code editions are being enforced?') still displays the pre-7/1/2026 edition list; re-checked live 2026-07-16, page text is byte-identical to the earlier fetch: 'The city is currently enforcing the following codes: 2021 Edition of the International Building Code, 2021 Edition of the International Residential Code, 2021 Edition of the International Plumbing Code, 2021 Edition of the International Mechanical Code, 2021 Edition of the National Electrical Code, 2021 Edition of the International Fuel Gas Code, 2021 Edition of the International Fire Code, 2009 Edition of the International Building Code (ICC/ANSI A117.1) for Accessibility Standards.' State law governs regardless of the page's lag; each line below states current law first, then the page's as-published (stale or omitted) text.; 2024 Edition of the International Building Code (IBC) — per Utah Code § 15A-2-103(1)(a), effective 7/1/2026. South Ogden's FAQ still lists '2021 Edition of the International Building Code' (live re-check 2026-07-16).; 2021 Edition of the International Residential Code (IRC), plus Appendix AQ of the 2021 IRC — per Utah Code § 15A-2-103(1)(b)/(c); this edition did NOT change in the 7/1/2026 flip. Matches South Ogden's FAQ, which lists '2021 Edition of the International Residential Code' (live re-check 2026-07-16).; 2024 Edition of the International Plumbing Code (IPC) — per Utah Code § 15A-2-103(1)(d), effective 7/1/2026. South Ogden's FAQ still lists '2021 Edition of the International Plumbing Code' (live re-check 2026-07-16).; 2024 Edition of the International Mechanical Code (IMC) — per Utah Code § 15A-2-103(1)(e), effective 7/1/2026. South Ogden's FAQ still lists '2021 Edition of the International Mechanical Code' (live re-check 2026-07-16).; 2023 Edition of the National Electrical Code (NEC) — per Utah Code § 15A-2-103(1)(g); this edition did NOT change in the 7/1/2026 flip and has been state law since before this project's original 2026-07-07 review. South Ogden's FAQ still lists '2021 Edition of the National Electrical Code' (live re-check 2026-07-16) — this is a PRE-EXISTING discrepancy that predates and is unrelated to the 2026-07-01 code-cycle flip (South Ogden's page was already citing a stale NEC edition under the prior law too); reported here as-published rather than corrected, per grounded-data policy of not inventing a fact the city's own source does not state.; 2024 Edition of the International Fuel Gas Code (IFGC) — per Utah Code § 15A-2-103(1)(f), effective 7/1/2026. South Ogden's FAQ still lists '2021 Edition of the International Fuel Gas Code' (live re-check 2026-07-16).; 2024 International Energy Conservation Code (IECC), one statewide edition (no residential/commercial split) — per Utah Code § 15A-2-103(1)(h), effective 7/1/2026. Not mentioned on South Ogden's FAQ, department page, Forms page, or City Fee Schedule as of live re-check 2026-07-16; added here as a statute-sourced omission (applies statewide regardless of city publication), not fabricated.; 2024 International Existing Building Code (IEBC) — per Utah Code § 15A-2-103(1)(i), effective 7/1/2026. Not mentioned on any South Ogden source reviewed as of live re-check 2026-07-16; added as a statute-sourced omission.; Residential provisions of the 2024 International Swimming Pool and Spa Code (ISPSC) — per Utah Code § 15A-2-103(1)(n), effective 7/1/2026. Not mentioned on any South Ogden source reviewed as of live re-check 2026-07-16; added as a statute-sourced omission.; Modular Building Institute (MBI) Standards 1200 and 1205 — per Utah Code § 15A-2-103(1)(o), statewide-mandated for modular units. Not mentioned on any South Ogden source reviewed as of live re-check 2026-07-16; added as a statute-sourced omission.; 2021 Edition of the International Fire Code (IFC) — per the official FAQ page (live re-check 2026-07-16, unchanged); South Ogden City Code Title 3, Chapter 1 separately adopts by reference 'the International Fire Code version adopted by the State of Utah Fire Marshal's Office for the respective year' (Ordinance 24-05, effective 2 Jul 2024), so the specific IFC edition in force tracks the State Fire Marshal's current adoption. NOTE: Utah Code § 15A-2-103 does NOT adopt the IFC — it is separately governed under Title 15A Chapter 5, outside the scope of this section; South Ogden's IFC citation and Fire Code ordinance are therefore unaffected by, and not mis-scoped to, § 15A-2-103.; 2009 Edition of the International Building Code (ICC/ANSI A117.1) for Accessibility Standards — per the official FAQ page (live re-check 2026-07-16, unchanged). This accessibility standard is not among the codes enumerated in Utah Code § 15A-2-103(1); reproduced here as South Ogden's own published statement, not itself corrected against that section.; Utah's statewide construction-code framework under Utah Code Title 15A (State Construction and Fire Codes Act) governs code adoption and amendment authority for all Utah municipalities, including South Ogden; § 15A-2-103 is now the direct authority used above for the codes it enumerates, since South Ogden's own FAQ page has not been updated to reflect the 7/1/2026 edition changes.. Local amendments apply — see the South Ogden overview page for the full list.
