Woods Cross, Utah has adopted: 2021 International Residential Code (IRC) with Appendix AE and AQ — REMAINS CURRENT per Utah Code § 15A-2-103(1)(b)/(c), UNCHANGED by the 7/1/2026 statewide amendment. Consistent with Woods Cross City's official Building Codes and Design Criteria handout (re-fetched live 2026-07-16, unchanged).; 2015 International Residential Code Chapter 11 (residential energy provisions) — CORRECTED/SUPERSEDED: Utah Code § 15A-2-103(1)(h) adopts a single unsplit 2024 IECC statewide as of 7/1/2026 (see the consolidated IECC entry below); this pre-existing residential-energy carve-out to the 2015 edition no longer reflects the current statute. Woods Cross's own Building Codes and Design Criteria handout (re-fetched live 2026-07-16) still lists '2015 International residential Code Chapter 11' under 'RESIDENTIAL BUILDING CODES' and has not been updated — preserved here as recorded history, not deleted.; 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. Woods Cross's Building Codes and Design Criteria handout (re-fetched live 2026-07-16) still lists '2021 International Swimming Pool and Spa Code' and has not been updated.; 2024 International Building Code (IBC) with Appendix C and J — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(a); supersedes the 2021 edition. Woods Cross's handout labels this 'COMMERCIAL CONSTRUCTION BUILDING CODES' but § 15A-2-103 does not itself carry a residential/commercial IBC split — the IBC applies per the statute regardless of the handout's section heading. Woods Cross's handout (re-fetched live 2026-07-16) still lists '2021 International Building Code with Appendix C and J' and has not been updated.; 2024 International Mechanical Code (IMC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(e); supersedes the 2021 edition. Woods Cross's handout (re-fetched live 2026-07-16) still lists '2021 International Mechanical Code' and has not been updated.; 2021 International Fire Code (IFC) — per Woods Cross City Building Codes and Design Criteria handout; NOTE: the IFC is adopted under Utah Code Title 15A Chapter 5, not § 15A-2-103 (which governs the IBC/IRC/IPC/IMC/IFGC/IECC/IEBC/NEC/residential-ISPSC/MBI editions in this array) — § 15A-2-103 does not itself adopt or list an IFC edition, so this entry is unaffected by the 7/1/2026 § 15A-2-103 amendment.; 2024 International Plumbing Code (IPC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(d); supersedes the 2021 edition. Woods Cross's handout (re-fetched live 2026-07-16) still lists '2021 International Plumbing Code' and has not been updated.; 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. Woods Cross's handout (re-fetched live 2026-07-16) still lists '2021 International Fuel Gas Code' and has not been updated.; 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 both the 2021 edition Woods Cross's handout lists under 'COMMERCIAL CONSTRUCTION BUILDING CODES' and the 2015 IRC Chapter 11 residential-energy carve-out listed separately under 'RESIDENTIAL BUILDING CODES' (see history entry above) — § 15A-2-103 does not carry a residential/commercial IECC split. Woods Cross's handout (re-fetched live 2026-07-16) has not been updated for either.; 2023 National Electrical Code (NEC) — CURRENT statewide per Utah Code § 15A-2-103(1)(g); UNCHANGED by the 7/1/2026 amendment (2023 has been the statewide NEC edition since before this cycle). CORRECTED: Woods Cross City's Building Codes and Design Criteria handout (re-fetched live 2026-07-16, unchanged) lists '2020 National Electrical Code,' which is NOT a valid statewide-adopted edition — this file previously flagged the discrepancy but had not yet cited the statute directly or resolved which edition is correct; the statute controls and 2023 is confirmed correct. Confirm the currently enforced NEC edition directly with the Building Department before relying on the City's own document for a live project.; 2024 International Existing Building Code (IEBC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(i); supersedes the 2021 edition. Woods Cross's handout (re-fetched live 2026-07-16) still lists '2021 International Existing Building Code' and has not been updated.; 2009 ICC/ANSI A117.1 Accessible and Usable Buildings and Facilities — per Woods Cross City Building Codes and Design Criteria handout; not governed by § 15A-2-103, which does not itself adopt an ICC/ANSI A117.1 edition.; MBI 1200 and MBI 1205 (manufactured/modular construction standards) — statewide per Utah Code § 15A-2-103(1)(o); not itemized in Woods Cross's own Building Codes and Design Criteria handout, added here per statute.; All codes above are noted on the city's official handout as 'As adopted by the State of Utah. See Utah Code Title 15A for a complete list of adopted codes and amendments.'; 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. IBC/IPC/IMC/IFGC/IECC/IEBC/residential ISPSC are now 2024 statewide; IRC (2021) and NEC (2023) did NOT change. Woods Cross's own Building Codes and Design Criteria handout was re-fetched live 2026-07-16 and is unchanged: it still lists 2021 IBC/IMC/IPC/IFGC/IECC/IEBC/ISPSC, a 2015 IRC Chapter 11 residential-energy carve-out, and an outright incorrect '2020 National Electrical Code' — none of these have been updated by the City to reflect the statewide 7/1/2026 transition or the pre-existing 2023 NEC requirement. The statute is cited directly as governing throughout; the City's lagging handout is preserved above as recorded history, not deleted.. Local amendments apply — see the Woods Cross overview page for the full list.
