CMC § 10.03.070 (adopted by Ord. 2017-03, amended by Ord. 2018-16 6/19/2018, amended by Ord. 2025-04, and MOST RECENTLY amended by Ord. 2026-03 on 3/3/2026 — Centerville's most recently touched construction-code chapter) is correct and confirms the 2023 edition, consistent with statute.; 2024 International Energy Conservation Code (IECC), single unsplit statewide edition — CURRENT as of 7/1/2026 per Utah Code § 15A-2-103(1)(h); supersedes the 2021 edition CMC § 10.03.080 still codifies as of live re-check 2026-07-16 (last amended by Ord. 2025-04, 4/1/2025).; 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 CMC § 10.03.085 still codifies as of live re-check 2026-07-16 (last amended by Ord. 2025-04, 4/1/2025).; 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 CMC § 10.03.122 (Swimming Pools And Spa Code, adopted by Ord. 2025-04, 4/1/2025) still codifies — confirmed by live browser re-check 2026-07-16 (the JavaScript-rendered code viewer that previously blocked static text extraction was successfully read this session): 'The residential provisions of the Swimming Pool and Spa Code, 2021 Edition ... are hereby adopted.'; Manufactured Housing standards per Utah Code § 15A-2-104, plus the HUD Code, Appendix AE of the 2021 IRC, and the 2005 NFPA 225 Model Manufactured Home Installation Standard — adopted by Ord. 2017-03, amended by Ord. 2025-04, per CMC § 10.03.090. Not affected by the § 15A-2-103 7/1/2026 amendment (governed by § 15A-2-104 instead).; Uniform Code for the Abatement of Dangerous Buildings, 1997 Edition — adopted by Ord. 2017-03, amended by Ord. 2025-04, per CMC § 10.03.100. Not a § 15A-2-103 code; unaffected by the 7/1/2026 amendment.; International Property Maintenance Code, 2006 Edition — adopted by Ord. 2017-03, amended by Ord. 2025-04, per CMC § 10.03.110.

CORRECTION (2026-07-16): this file's prior entry described the IFC edition as '2015 Edition per the 2017 code compilation text' and reported the full CMC § 10.03.120 text as unextractable due to JavaScript rendering — both are superseded by a successful live browser re-read of centerville.municipalcodeonline.com on 2026-07-16, which returned full section text confirming the 2021 IFC (not 2015) is currently codified. The IFC is NOT among the codes adopted by Utah Code § 15A-2-103 (Title 15A Chapter 2, State Construction Code) — Utah's Fire Code is separately adopted under Title 15A Chapter 5, State Fire Code Act — so no statutory edition change via § 15A-2-103 applies to this entry regardless.; International Wildland-Urban Interface (WUI) Code — CMC § 10.03.125, confirmed via live browser re-read 2026-07-16 (previously unextractable): the 2006-edition Utah WUI Code (adopted by Ord. 2017-03, per Utah Code Title 65A Ch. 8) governs UNTIL January 1, 2027, at which point the 2024-edition International WUI Code (adopted by Ord. 2026-03 on 3/3/2026, amended by Ord. 2026-09 on 4/21/2026) takes over per a dual-dated code section. This is a Title 15A Ch. 2 local-amendment-adoptable code under § 15A-2-103(2), distinct from the seven codes listed in § 15A-2-103(1) that are the focus of this file's 7/1/2026 update.; NOTE (2026-07-16 re-verification): The 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. Centerville Municipal Code Title 10.03 was live re-read in full via browser (centerville.municipalcodeonline.com, JavaScript-rendered — the WebFetch tool that previously reported this content as unextractable returns only template chrome; the Browser pane renders full section text) on 2026-07-16 and IS STILL LAGGING on every code family Utah Code § 15A-2-103(1) bumped to 2024: IBC/IPC/IMC/IFGC/IECC/IEBC/ISPSC(residential) all remain codified at their pre-7/1/2026 (2021) editions, most recently touched by Ord. 2025-04 (4/1/2025), which predates the statute's effective date. The NEC section (§ 10.03.070, amended by Ord. 2026-03 on 3/3/2026 — Centerville's most recent construction-code ordinance) is CORRECT at 2023, and the IRC section is correctly unchanged at 2021.
