Codes 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). Consistent with Riverdale City's official Building Inspections page, which states: '2024 International Building Code (IBC) (Effective July 1, 2026, the 2024 codes will be required).'2021 International Residential Code (IRC) — CORRECTED. Utah Code § 15A-2-103(1)(b) did NOT change the IRC edition in the 7/1/2026 statewide amendment; the IRC REMAINS the 2021 edition. Riverdale City's own official Building Inspections page (live-checked 2026-07-16, HTTP 200, 51531 bytes) states verbatim: '2024 International Residential Code (IRC)' — this is factually WRONG; no provision of § 15A-2-103 adopts a 2024 IRC. This entry previously repeated the City's incorrect 2024 figure; the statute controls and the correct current edition is 2021. The City's incorrect claim is preserved here as a recorded conflict, not deleted — see the dated note below and the matching sibling defect on syracuse-ut's page, which similarly asserts an incorrect 2024/unchanged-2024 IRC.Appendix AQ of the 2021 IRC — statewide per Utah Code § 15A-2-103(1)(c); not itemized on Riverdale's own Building Inspections page, added here per statute.2024 International Mechanical Code (IMC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(e).

Consistent with Riverdale's official Building Inspections page, which lists it (with an apparent typo, 'IG' rather than 'IFGC') as: '2024 International Fuel Gas Code (IG) (Effective July 1, 2026, the 2024 codes will be required).'2024 International Energy Conservation Code (IECC), single unsplit statewide edition — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(h). Consistent with Riverdale's official Building Inspections page: '2024 International Energy Conservation Code (IECC) (Effective July 1, 2026, the 2024 codes will be required).'2023 National Electrical Code (NEC) — CORRECTED. Utah Code § 15A-2-103(1)(g) did NOT change the NEC edition in the 7/1/2026 statewide amendment; the NEC REMAINS the 2023 edition (unchanged since before this cycle). Riverdale City's own official Building Inspections page (live-checked 2026-07-16, HTTP 200, 51531 bytes) states verbatim: '2024 National Electrical Code (NEC) remains in effect' — this is factually WRONG on two counts: no provision of § 15A-2-103 adopts a 2024 NEC, and the word 'remains' is itself incorrect since the statewide NEC has never been the 2024 edition. This entry previously repeated the City's incorrect 2024 figure; the statute controls and the correct current edition is 2023. The City's incorrect claim is preserved here as a recorded conflict, not deleted — see the dated note below and the matching sibling defect on syracuse-ut's page.2024 International Existing Building Code (IEBC) — statewide per Utah Code § 15A-2-103(1)(i); not itemized on Riverdale's own Building Inspections page, added here per statute since the City's own materials omit it.Residential provisions of the 2024 International Swimming Pool and Spa Code (ISPSC) — statewide per Utah Code § 15A-2-103(1)(n); not itemized on Riverdale's own Building Inspections page, added here per statute since the City's own materials omit it.MBI 1200 and MBI 1205 (manufactured/modular construction standards) — statewide per Utah Code § 15A-2-103(1)(o); not itemized on Riverdale's own Building Inspections page, added here per statute since the City's own materials omit it.NOTE (2026-07-16 re-verification — City page vs. statute conflict): Riverdale City's official Building Inspections page (riverdaleutah.gov/business/building_inspections/index.php, live-checked 2026-07-16, HTTP 200, 51531 bytes) is headed 'Building Code Changes - Effective July 1, 2026' and states verbatim: 'Effective July 1, 2026, the State of Utah adopted the following statewide codes: 2024 International Building Code (IBC) (Effective July 1, 2026, the 2024 codes will be required) / 2024 International Residential Code (IRC) / 2024 International Mechanical Code (IMC) (Effective July 1, 2026, the 2024 codes will be required) / 2024 International Plumbing Code (IPC) (Effective July 1, 2026, the 2024 codes will be required) / 2024 International Fuel Gas Code (IG) (Effective July 1, 2026, the 2024 codes will be required) / 2024 International Energy Conservation Code (IECC) (Effective July 1, 2026, the 2024 codes will be required) / 2024 National Electrical Code (NEC) remains in effect.' Utah Code § 15A-2-103 (version effective 7/1/2026, superseded 1/1/2027, read live 2026-07-16) does NOT adopt a 2024 IRC or a 2024 NEC — the statute keeps the IRC at 2021 (§(1)(b), unchanged) and the NEC at 2023 (§(1)(g), unchanged). Riverdale's own page is simply incorrect on these two codes (the IBC/IMC/IPC/IFGC/IECC entries at 2024 are all correct and consistent with the statute). This mirrors a documented pattern on sibling jurisdiction syracuse-ut, whose own page similarly misstates the IRC. The statute governs; the City's page text is quoted above and preserved as the recorded conflict, not deleted or silently corrected without explanation.

Commercial Building Permit
VerifiedRequired for new commercial or manufacturing construction in Riverdale. The city's 'Building and Sign Permit Fee Schedule' is a single valuation-based table shared by all building permit types, including commercial — Riverdale does not publish a separate commercial valuation tier or plan-check percentage. New commercial and manufacturing projects additionally require a distinct Planning Commission and City Council Site Plan Review, which is a materially larger and slower process than the building permit fee itself.

Commercial Tenant Improvement / Tenant Finish Permit
Required for tenant improvement and interior remodel work in an existing, already-approved commercial building in Riverdale. Uses the same shared Building and Sign Permit Fee Schedule as new commercial construction. Riverdale separately publishes an 'Application for Amended Commercial or Manufacturing Site Plan Approval' for changes to a previously approved commercial site plan — the city's public materials do not specify a scope threshold for when interior-only tenant improvements trigger this amendment, so that determination is noted here rather than assumed.
