    Tips

    • A shed or detached garage under 200 sq. ft. with NO electrical, mechanical, or plumbing added requires no building permit at all in West Haven — but adding even a single electrical circuit triggers the full permit requirement regardless of size.
    • The over-200-sq.-ft. setback rules (8 ft side / 10 ft rear) are stricter than the under-200-sq.-ft. rules (5 ft property line / 6 ft from dwelling) — don't assume the smaller-structure setbacks apply to a larger shed.

    West Haven, Utah has adopted: 2024 International Building Code (IBC), including Appendices C and J — current statewide code per Utah Code § 15A-2-103(1)(a), in force since July 1, 2026 (superseded the 2021 IBC). NOTE: West Haven City's own official Building Department page has NOT been updated for this flip — re-checked live 2026-07-16, it still reads '2021 International Building Code (IBC) (Effective July 1, 2026, the 2024 codes will be required)', future-tense language that is now stale since that date has passed. The statewide-adopted 2024 edition governs regardless of the city's unrevised page.; 2021 International Residential Code (IRC) — current statewide code per Utah Code § 15A-2-103(1)(b), unchanged by the July 1, 2026 code cycle flip; 2024 International Mechanical Code (IMC) — current statewide code per Utah Code § 15A-2-103(1)(e), in force since July 1, 2026 (superseded the 2021 IMC). the statewide-adopted 2024 edition governs.; 2024 International Plumbing Code (IPC) — current statewide code per Utah Code § 15A-2-103(1)(d), in force since July 1, 2026 (superseded the 2021 IPC). NOTE: West Haven's official Building Department page uses the same stale future-tense '2021... (Effective July 1, 2026, the 2024 codes will be required)' phrasing; the statewide-adopted 2024 edition governs.; 2024 International Fuel Gas Code (IFGC) — current statewide code per Utah Code § 15A-2-103(1)(f), in force since July 1, 2026 (superseded the 2021 IFGC). NOTE: West Haven's official Building Department page uses the same stale future-tense phrasing. The city's Residential Basement Finish guide separately cites IFGC 406.4 (concealed gas piping air test) as an active code reference, unaffected by the edition-number update.; 2024 International Energy Conservation Code (IECC) — current statewide code per Utah Code § 15A-2-103(1)(h), in force since July 1, 2026 (superseded the 2021 IECC; one edition applies statewide, no separate residential/commercial split).; 2023 National Electrical Code (NEC) — current statewide code per Utah Code § 15A-2-103(1)(g), unchanged by the July 1, 2026 code cycle flip. NOTE: this is a SEPARATE, pre-existing error on West Haven's official Building Department page (unrelated to the July 1, 2026 code-cycle flip) — the page states '2020 National Electrical Code (NEC) remains in effect,' re-confirmed live 2026-07-16. The 2023 NEC has been the statewide-adopted edition since before the prior verification (2026-07-07); the city's page has not been corrected.; Utah Code Title 15A, Chapter 3 (State Amendments to the adopted construction codes) — referenced directly by the city's Building Department page via a 'Utah State Amendments' link to the Utah Legislature's own code text.. Local amendments apply — see the West Haven overview page for the full list.
