Alpine, Utah has adopted: 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; per Alpine City's official Building Permit Instructions (New Home Form #2, revised 4/9/2025): 'Structural design criteria must conform to the 2021 IRC.'; 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 Alpine City's official Building Permit Instructions (New Home Form #2, revised 4/9/2025) still cited as of live-check 2026-07-16: 'I understand that it is my responsibility to comply with Alpine City Zoning Ordinances and the I.B.C. 2021 code (including Appendix C and J) as adopted by Alpine City.'; 2021 IRC Appendix AL (Building Permit Fees) as amended by Alpine City — Alpine's Consolidated Fee Schedule (effective November 11, 2025), Appendix B, is expressly titled 'Building Permit Fees (2021 IRC Appendix AL, as amended)' and cites https://codes.iccsafe.org/content/IRC2021P2/appendix-al-permit-fees. This is a local fee-table appendix reference, not the § 15A-2-103 construction-code edition, and is unaffected by the 7/1/2026 code-cycle update.; Utah statewide baseline construction code editions per Utah Code § 15A-2-103, effective 7/1/2026 (superseded 1/1/2027): 2024 IPC (§(1)(d)), 2024 IMC (§(1)(e)), 2024 IFGC (§(1)(f)), 2024 IECC as a single unsplit statewide edition (§(1)(h)), 2024 IEBC (§(1)(i)), and the residential provisions of the 2024 ISPSC (§(1)(n)) — none separately itemized in Alpine's own published materials (Consolidated Fee Schedule, Building Permit Instructions, Building Department page); added here per statute since Alpine's own documents omit them. The 2023 NEC (§(1)(g)) also applies statewide but is likewise not separately restated by Alpine — unchanged by the 7/1/2026 amendment.; NOTE (2026-07-16 re-verification): The Utah Code § 15A-2-103 version effective 7/1/2026 (superseded 1/1/2027) took effect 15 days before this re-verification.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. Alpine City's official Building Permit Instructions (New Home Form #2) — the sole cited source for Alpine's code editions — was live-checked 2026-07-16 by re-fetching the PDF directly and remains dated 'Revised 4/9/2025' with no update: it still states 'Structural design criteria must conform to the 2021 IRC' (correct, unchanged) and 'the I.B.C. 2021 code (including Appendix C and J) as adopted by Alpine City' (STALE — Alpine has not published an updated form reflecting the 2024 IBC as of this date). No newer Alpine-specific building-code publication was found on alpineut.gov. The Utah Code § 15A-2-103 citation added to the sources array below points to the current in-force version link..
