American Fork, 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 American Fork's official Building Department page still stated as of live-check 2026-07-16: 'the American Fork Building Department uses the 2021 IBC and IRC Code as adopted by the State of Utah,' effective July 1, 2023, per americanfork.gov/173/Building-Department. The 2021 edition applied under the prior version of § 15A-2-103; American Fork's page has not been updated to reflect the 7/1/2026 transition.; 2021 International Residential Code (IRC) — REMAINS CURRENT, Utah Code § 15A-2-103(1)(b) did not change this edition in the 7/1/2026 amendment; americanfork.gov/173/Building-Department's statement is correct on this point (no update needed for IRC).; 2020 National Electrical Code (NEC) as published by American Fork's own Solar Minimum Plan Requirements checklist — STALE even under the PRIOR version of the statute: the checklist (americanfork.gov/DocumentCenter/View/13852/Solar-Checklist) explicitly cites '2020 NEC 690.4(C)' and multiple other 2020 NEC section references (690.7, 690.12, 706.15(C), 230.71, 230.62(C)), fetched 2026-07-04 and unconfirmed changed since. The statewide-governing NEC edition is, and remains, the 2023 NEC per Utah Code § 15A-2-103(1)(g) — unchanged by the 7/1/2026 amendment, but American Fork's own document has not been updated to reference it, a pre-existing discrepancy independent of the 2026 code-cycle transition (the same kind of stale-document issue documented for Provo's Building FAQ in provo.json). 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 International Energy Conservation Code (IECC), single unsplit statewide edition — CURRENT as of 7/1/2026 per Utah Code § 15A-2-103(1)(h); required per American Fork City Residential Plans Minimum Plan Requirements checklist (americanfork.gov/DocumentCenter/View/58/Residential-Plan-Checklist): 'Utah Energy Conservation Code requirements. Must have lot, subdivision, and plan number on the Res check submittal.' The checklist itself does not state a specific edition year — the 2024 edition is added here per statute.; Utah statewide baseline construction code editions per Utah Code § 15A-2-103, effective 7/1/2026 (superseded 1/1/2027): 2024 IPC (§(1)(d)), 2024 IMC (§(1)(e)), 2024 IFGC (§(1)(f)), 2024 IEBC (§(1)(i)), and the residential provisions of the 2024 ISPSC (§(1)(n)) — none separately itemized on americanfork.gov/173/Building-Department or in American Fork's own checklists; added here per statute since American Fork's own materials omit them.; 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. American Fork's Building Department page (americanfork.gov/173/Building-Department) was live-checked 2026-07-16 and IS STILL LAGGING: it verbatim states 'Beginning July 1, 2023, The American Fork Building Department will be using the 2021 IBC and IRC Code as adopted by the State of Utah' with no update reflecting the 2024 IBC. The IRC portion of that statement remains accurate (2021 IRC is unchanged). No newer American Fork-specific code-adoption notice was found. The Utah Code § 15A-2-103 citation has been added to the sources array below, pointing to the current in-force version link..
