Roy, Utah has adopted: GOVERNING LAW: Utah Code § 15A-2-103 (le.utah.gov/xcode/Title15A/Chapter2/15A-2-S103.html), version effective 7/1/2026 (amended by Ch. 47, 2026 General Session), sets the statewide-mandatory construction code suite (Utah Code § 15A-1-204 — binds every municipality; local amendments permitted, a different edition is not). Roy City's Building Permits & Inspections page still displays the pre-7/1/2026 edition list; re-checked live 2026-07-16, page text is byte-identical to the earlier fetch: 'Roy City has adopted minimum design and construction requirements found in the state amended 2021 IBC, IPC, IMC, IFGC and IRC, as well as the 2020 NEC.' State law governs regardless of the page's lag; each line below states current law first, then the page's as-published (stale or omitted) text.; 2024 International Building Code (IBC), state-amended — per Utah Code § 15A-2-103(1)(a), effective 7/1/2026. Roy City's Building Permits & Inspections page still lists 'the state amended 2021 IBC' (live re-check 2026-07-16).; 2021 International Residential Code (IRC), state-amended, including Appendix AQ — per Utah Code § 15A-2-103(1)(b)/(c); this edition did NOT change in the 7/1/2026 flip. Matches Roy City's page, which lists 'the state amended ... IRC' as 2021 (live re-check 2026-07-16).; 2024 International Plumbing Code (IPC), state-amended — per Utah Code § 15A-2-103(1)(d), effective 7/1/2026. Roy City's page still lists 'the state amended 2021 ... IPC' (live re-check 2026-07-16).; 2024 International Mechanical Code (IMC), state-amended — per Utah Code § 15A-2-103(1)(e), effective 7/1/2026. Roy City's page still lists 'the state amended 2021 ... IMC' (live re-check 2026-07-16).; 2024 International Fuel Gas Code (IFGC), state-amended — per Utah Code § 15A-2-103(1)(f), effective 7/1/2026. Roy City's page still lists 'the state amended 2021 ... IFGC' (live re-check 2026-07-16).; 2023 National Electrical Code (NEC) — per Utah Code § 15A-2-103(1)(g); this edition did NOT change in the 7/1/2026 flip. Roy City's page still lists 'the 2020 NEC' (live re-check 2026-07-16) — this is a PRE-EXISTING discrepancy that predates and is unrelated to the 2026-07-01 code-cycle flip (the 2023 NEC has been state law since before this project's original review), of the same kind documented for American Fork's Solar Checklist and Provo's Building FAQ. 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), one statewide edition (no residential/commercial split) — per Utah Code § 15A-2-103(1)(h), effective 7/1/2026. Not mentioned anywhere on Roy City's Building Permits & Inspections page, its permit-information handouts, or its Consolidated Fee Schedule as of live re-check 2026-07-16; added here as a statute-sourced omission (applies statewide regardless of city publication), not fabricated.; 2024 International Existing Building Code (IEBC) — per Utah Code § 15A-2-103(1)(i), effective 7/1/2026. Not mentioned on any Roy City source reviewed as of live re-check 2026-07-16; added as a statute-sourced omission.; Residential provisions of the 2024 International Swimming Pool and Spa Code (ISPSC) — per Utah Code § 15A-2-103(1)(n), effective 7/1/2026. Not mentioned on any Roy City source reviewed as of live re-check 2026-07-16, despite the city offering a Residential Swimming Pools permit info page; added as a statute-sourced omission.; Modular Building Institute (MBI) Standards 1200 and 1205 — per Utah Code § 15A-2-103(1)(o), statewide-mandated for modular units. Not mentioned on any Roy City source reviewed as of live re-check 2026-07-16; added as a statute-sourced omission.; No International Fire Code (IFC) entry: § 15A-2-103 does not adopt the IFC — it is separately governed under Title 15A Chapter 5, outside the scope of this section. Roy City's page does not list an IFC edition either, so there is no mis-citation to correct here.; Roy City Design Criteria (site-specific structural values published alongside the adopted-codes statement on the same Building Permits & Inspections page): Ground Snow Load 40 psf; Wind Speed 120 mph, Exposure B or C; Seismic Design Category D0; Frost Depth 30 inches below grade..
