Codes adopted

Utah adopts construction codes statewide under Utah Code Title 15A (State Construction and Fire Codes Act), enforced by every jurisdiction. Chapter 4 of Title 15A codifies Legislature-enacted amendments for specific named jurisdictions (e.g., Park City, Salt Lake City, Sandy City) as part of the state construction code. Through June 30, 2026, the editions in force under Utah Code § 15A-2-103 are the 2021 IBC (with Appendices C and J), 2021 IRC, 2021 IPC, 2021 IMC, 2021 IFGC, 2021 IECC, 2021 IEBC, and 2021 ISPSC (residential provisions), together with the 2023 NEC. Effective July 1, 2026, § 15A-2-103 adopts the 2024 editions of the IBC, IPC, IMC, IFGC, IECC, IEBC, and ISPSC; the IRC remains the 2021 edition and the NEC remains the 2023 edition. Note: residential energy requirements are modified by statewide amendments, and several Utah jurisdictions document their residential energy provisions at the 2015 IECC level rather than the adopted IECC year — confirm the applicable residential energy code with your local jurisdiction. Always confirm the edition in force with your local jurisdiction.

• 2024 International Building Code (IBC), including Appendices C and J — Riverton City Code § 15.10.010 (dynamic adoption clause: 'the most recent version... adopted by the state of Utah... [with] adoption of updated versions by the state of Utah after the date of this chapter [having] the effect of updating Riverton City's building code(s)'); Utah Code § 15A-2-103(1)(a); effective 2026-07-01, superseded the 2021 edition that had been in effect since July 1, 2023
• 2021 International Residential Code (IRC), including Appendices AE and AQ — Riverton City Code § 15.10.010; Utah Code § 15A-2-103(1)(b)/(c)/(k); unchanged by the 7/1/2026 code cycle
• 2024 International Plumbing Code (IPC) — Riverton City Code § 15.10.010; Utah Code § 15A-2-103(1)(d); effective 2026-07-01, superseded the 2021 edition that had been in effect since July 1, 2023
• 2024 International Mechanical Code (IMC) — Riverton City Code § 15.10.010; Utah Code § 15A-2-103(1)(e); effective 2026-07-01, superseded the 2021 edition that had been in effect since July 1, 2023
• 2024 International Fuel Gas Code (IFGC) — Riverton City Code § 15.10.010; Utah Code § 15A-2-103(1)(f); effective 2026-07-01, superseded the 2021 edition that had been in effect since July 1, 2023
• 2023 National Electrical Code (NEC) — Utah Code § 15A-2-103(1)(g); statewide adoption; unchanged by the 7/1/2026 code cycle; also listed on rivertonutah.gov/building/code.php
• Residential provisions of Chapter 11, Energy Efficiency, of the 2015 International Residential Code — rivertonutah.gov/building/code.php item 7 (verified live 2026-07-16, wording unchanged from before this fix); Riverton's own residential-energy baseline citation, distinct from the statewide IECC line below and NOT altered by the 7/1/2026 code cycle per the city's own current page
• 2024 International Energy Conservation Code (IECC), commercial provisions — Riverton City Code § 15.10.010; Utah Code § 15A-2-103(1)(h); effective 2026-07-01, superseded the 2021 edition that had been in effect since July 1, 2023
• 2024 International Existing Building Code (IEBC) — Riverton City Code § 15.10.010; Utah Code § 15A-2-103(1)(i); effective 2026-07-01, superseded the 2021 edition that had been in effect since July 1, 2023

• NOTE (verified 2026-07-16): Riverton's own 'Building Codes in Use in Riverton City' list at rivertonutah.gov/building/code.php is headed 'Effective July 1, 2023' and still enumerates the 2021 IBC/IRC/IPC/IMC/IFGC, 2021 IEBC, and 2021 ISPSC, plus 'Commercial provisions of the 2021 International Energy Conservation Code' — that page has NOT been updated for the 7/1/2026 code cycle. However, Riverton City Code § 15.10.010 itself dynamically adopts 'the most recent version... adopted by the state of Utah' and states that state updates automatically update Riverton's code with no separate city action required — so as a matter of law the 2024 editions already govern in Riverton regardless of the outdated summary page. Confirmed directly against Utah Code § 15A-2-103 (version effective 7/1/2026, superseded 1/1/2027) at le.utah.gov.

Permit types & fees

• Residential Building Permit

  Required for new residential construction, additions, structural alterations, and any work regulated by the adopted International Building Code or International Residential Code in Riverton. Riverton City Code § 15.10.010 adopts the state-current building codes by reference.

  →

• Electrical Permit

  Required for electrical work in Riverton including new circuits, panel upgrades, service changes, new construction wiring, and solar electrical connections. Governed by the 2023 National Electrical Code (NEC) adopted statewide by Utah Code § 15A-2-103(1)(g). EV charger/EVSE installation is electrical work and falls under this general Electrical Permit; a direct text search of Riverton's full FY2025-26/2026-27 Adopted Fee Schedule PDF (lines 165-185, BUILDING section) found no EV-, EVSE-, or electric-vehicle-specific line item — the standard valuation-based electrical fee applies.

  →

• Plumbing Permit

  Required for plumbing installations, alterations, and repairs in Riverton including water heaters, fixture additions, and pipe replacements. Governed by the 2024 International Plumbing Code (IPC) adopted per Riverton City Code § 15.10.010, effective 2026-07-01 (superseded the 2021 edition).

  →

• Mechanical / HVAC Permit

  Required for heating, ventilation, and air conditioning installations, replacements, and ductwork modifications in Riverton. Governed by the 2024 International Mechanical Code (IMC) adopted per Riverton City Code § 15.10.010, effective 2026-07-01 (superseded the 2021 edition).

  →

• Roofing Permit (Re-Roof)

  Required for roof replacement and re-roofing in Riverton. Riverton charges a flat fee for re-roof permits, distinct from the valuation-based building permit fee.

  →

• Solar Panel Permit

  Required for installation of rooftop or ground-mounted solar photovoltaic (PV) systems in Riverton. Riverton charges a flat permit fee plus a plan check fee for solar installations.

  →

• Deck Permit

  Required for new deck construction or structural modifications to existing decks in Riverton. Permit fees are valuation-based using a square-footage multiplier to calculate the valuation, then the UBC 1-A table.

  →

• Basement Finish Permit

  Required for finishing or remodeling an unfinished basement in Riverton, including framing, electrical, plumbing, and HVAC work. Fees are valuation-based using a square-footage multiplier.

  →

• Demolition Permit

  Required for partial or complete demolition of structures in Riverton. Must include utility disconnection letters from all four utility providers and an asbestos/lead clearance letter from Utah DAQ before the permit is issued.

  →

• Accessory Dwelling Unit (ADU)

  Required for construction of a secondary dwelling unit on a residential property in Riverton, including basement apartments, detached cottages, and garage conversions. Riverton charges a $175 ADU fee (planning) plus a valuation-based building permit.

  →

• Commercial Building Permit

  Required for new commercial building construction, additions, and structural alterations in Riverton. Riverton does not use a separate commercial valuation table — the same Building Permit fee (based on the 1994 Modified UBC 1-A Fee Table, with valuation calculated using current ICC Valuation Tables) applies to commercial as to residential. Non-residential projects pay a higher Plan Check Fee (65% of the building permit fee) than single-family residential (45%), and are subject to non-residential-specific impact fees not charged on single-family permits.

  →

• Commercial Tenant Improvement / Tenant Finish Permit

  Required for tenant improvement (tenant finish) work in existing commercial buildings in Riverton — interior build-outs, remodels, and finish work for a new or changing tenant space. Riverton's Adopted Fee Schedule does not list a distinct tenant-improvement fee table; tenant improvement work is billed under the same non-residential Building Permit formula (1994 Modified UBC 1-A Fee Table, ICC-based valuation) plus the 65% Non-Residential Plan Check Fee, based on the value of the finish work.

  →

• Sign Permit

  Required for permanent and temporary signs in Riverton, per Riverton City Ordinance 18.150 (Sign Ordinance). Applications go to the Planning and Zoning Department. Submittals are preferred as email PDFs to Planning@rivertonutah.gov, with drawings as a separate PDF from the application.

  →

• Fire Sprinkler & Fire Alarm Permit

  Riverton City fire code enforcement is handled by the Unified Fire Authority (UFA), a regional special service district listed among Riverton City's own departments as "Fire (UFA)" — not the city Building Division. Per Section 104.7.2 of the International Fire Code, UFA requires a permit and a third-party "technical opinion and report" (peer review) for the installation or modification of automatic fire protection systems, fire alarm and detection systems, fire pumps, jockey pumps, controllers, and standpipe systems.

  →

• EV Charger / EVSE Permit

  Riverton City's FY2025-26 Adopted Fee Schedule has no standalone "Electrical Permit" or "EV Charger" line item — a full-text search of the schedule found zero mentions of "EV," "electric vehicle," "EVSE," or "charger." All electrical/trade work, including EV charger/EVSE installation, is priced through the same valuation-based table used for the general building permit (the 1994 Modified UBC 1-A Fee Table, with valuation set per the February 2020 ICC Building Valuation Data table), plus a 65% Plan Check Fee and 1% State of Utah Fee.

  →

• Change of Use / Certificate of Occupancy Compliance

  Riverton does not publish a standalone "Change of Use" permit, application, or fee — a full-text read of the FY2026-2027 Adopted Fee Schedule (all 314 line items across General Government, Planning & Zoning, Building, and Engineering) and the Planning & Zoning Applications page confirms no line item or downloadable application named "Change of Use," "Zoning Verification," or "Certificate of Occupancy." Instead, a change of use for an existing commercial building is governed through two folded-in city processes: (1) the Commercial Business License application, whose published Step 1 is a Zoning Verification review by Development Services/Planning confirming the new use complies with Riverton's land use and zoning ordinances (Riverton City Code Title 18) — performed at no charge, since the Commercial and Home-Based Business License application/renewal fee is $0.00 per the Adopted Fee Schedule (lines 1-2, in effect since July 2017/2018); and (2) for new construction or an occupancy-classification change, the Certificate of Occupancy Commercial Checklist — a multi-department/agency sign-off process (Building, Planning, Public Works-Bonding, LTSWMP, LDP & SWPPP, Engineering, Water/Meter Set, Fire, Backflow, and as-needed Jordan Basin Improvement District, Salt Lake County Health Department, State Boiler/Elevator Inspector, and Special Inspection Agency) that the Building Official must receive electronic approval on before a Certificate of Occupancy is issued. No separate CO fee is published; the standard $50 Inspections and $50 Re-Inspection line items (Adopted Fee Schedule, lines 179-180) cover this. If the change of use also involves construction or a Commercial Tenant Improvement, the valuation-based Building Permit fee (1994 Modified UBC 1-A Table) documented under Riverton's Residential Building Permit entry applies, including the Lot-Specific Geotechnical Soils Report required on all commercial building permits (rivertonutah.gov/building/index.php). Separately, Riverton City Code § 18.135.100(10) ("Change of Use," within Chapter 18.135, General Regulations) addresses change of use in the narrower context of nonconforming uses: "The nonconforming use of a building or structure may not be changed except to a conforming use, but where such change is made, the use shall not thereafter be changed back to a nonconforming use."
