Commercial Tenant Improvement / Tenant Finish Permit in Riverdale, Utah
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.

When you need this permit
- Tenant improvement / interior remodel work in an existing commercial building
- Building Permit Application submitted through the city's cityinspect.com portal
- If the tenant improvement alters elements of a previously approved site plan (e.g., footprint, parking, access), an Application for Amended Commercial or Manufacturing Site Plan Approval is required, per Riverdale's Forms & Permits page, at a fee of $400 per acre or portion of an acre — same rate as the original Site Plan Review application, per the Amended application's own PDF. The scope threshold for when this applies to interior-only work is not published: Riverdale City Code Title 10, Chapter 25 ('Development In All Zones,' §§10-25-1 through 10-25-5 — purpose/intent, definitions, scope of chapter, preapplication sketch plan, preliminary plan required) contains no floor-area, valuation, or interior-vs-exterior distinction governing when an amendment is required; §10-25-5(B) states only that 'amendments to the site plan shall be favorably recommended by the planning commission and approved by the city council,' without further qualification. Confirm with Community Development (801-394-5541 ext. 1276) before assuming a straightforward interior tenant improvement is exempt.

Tips
- Riverdale's tenant improvement work is billed on the exact same valuation-based fee schedule (65% Plan Check Fee plus 1% State Fee) as new commercial construction — there is no discounted tenant-improvement-specific tier.
- If your tenant improvement changes anything shown on a previously approved commercial site plan (footprint, parking, access), Riverdale's Forms & Permits page lists a separate 'Application for Amended Commercial or Manufacturing Site Plan Approval' — confirm with Community Development whether your specific scope triggers this.

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. Note: Riverdale City's own official Building Inspections page states '2024 International Residential Code (IRC)', but no provision of § 15A-2-103 adopts a 2024 IRC — the statute controls and the current edition is 2021. See the note below.; 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).

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.

See the note below.; 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 (City page vs. statute conflict, as of 2026-07-16): Riverdale City's official Building Inspections page (riverdaleutah.gov/business/building_inspections/index.php) 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) 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 incorrect on these two codes (the IBC/IMC/IPC/IFGC/IECC entries at 2024 are all correct and consistent with the statute). The statute governs; the City's page text is quoted above as the recorded conflict.. Local amendments apply — see the Riverdale overview page for the full list.
No. Riverdale bills tenant improvement work on the same Building and Sign Permit Fee Schedule, 65% Plan Check Fee, and 1% State of Utah Fee as new commercial construction — there is no separate, lower tenant-improvement tier.
