Vernal assesses solar PV permits on the same valuation-based Building Permit Fee table used for new construction (there is no flat solar fee) — for example, roughly $91 for the first $2,000 of valuation plus $12.75 per additional $1,000 in the $2,001–$25,000 bracket. This applies to both residential and commercial installations.

Vernal's published plan-review target for a solar panel (pv) permit is 7–7 business days.

Vernal, Utah has 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); supersedes the 2021 edition previously listed here. Vernal's own Building Division page (live-checked 2026-07-16) still does not list specific code edition years, describing only 'the Building Code' generically (electrical, plumbing, mechanical systems; energy conservation; fire safety; accessibility; structural requirements; wind resistance). No Vernal-specific ordinance publicly enumerating edition years was located — this entry follows the statewide baseline used consistently elsewhere in this corpus rather than asserting a city-specific adoption date that could not be independently verified.; 2021 International Residential Code (IRC) — REMAINS CURRENT; Utah Code § 15A-2-103(1)(b) did not change this edition in the 7/1/2026 statewide transition. Vernal's Residential Building Permits page confirms 'The International Residential Code is used for the minimum design standards for construction' without specifying an edition year.; Appendix AQ of the 2021 IRC — statewide per Utah Code § 15A-2-103(1)(c); not itemized on Vernal's own Building Division pages, added here per statute.; 2024 International Plumbing Code (IPC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(d); supersedes the 2021 edition previously listed here.; 2024 International Mechanical Code (IMC) — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(e); supersedes the 2021 edition previously listed here.; 2024 International Fuel Gas Code (IFGC) — statewide per Utah Code § 15A-2-103(1)(f); not itemized on Vernal's own Building Division pages, added here per statute since the City's own materials omit it.; 2024 International Energy Conservation Code (IECC), single unsplit statewide edition, with Utah amendments — CURRENT statewide as of 7/1/2026 per Utah Code § 15A-2-103(1)(h); supersedes the 2021 edition previously listed here.; 2023 National Electrical Code (NEC) — REMAINS CURRENT; Utah Code § 15A-2-103(1)(g) did not change this edition in the 7/1/2026 statewide transition (also consistent with Utah State Fire Marshal adoption).; 2024 International Existing Building Code (IEBC) — statewide per Utah Code § 15A-2-103(1)(i); not itemized on Vernal's own Building Division pages, 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 Vernal's own Building Division pages, added here per statute since the City's own materials omit it.; NOTE (2026-07-16 re-verification): Utah Code § 15A-2-103, version effective 7/1/2026 (superseded 1/1/2027), took effect 15 days before this re-verification. IBC/IPC/IMC/IFGC/IECC/IEBC/residential ISPSC are now 2024 statewide; IRC (2021) and NEC (2023) did NOT change. Vernal's Building Division page (vernal.gov/191/Building) was live-checked 2026-07-16 and still lists no specific code edition years at all — so no page-vs-statute lag could be detected; the statute is cited directly as governing throughout, unchanged from this file's prior no-lag finding.. Local amendments apply — see the Vernal overview page for the full list.

No — solar is processed as a type of Electrical Permit through Vernal's iWorQ citizen portal, but the City requires a dedicated Residential Solar Photovoltaic (PV) System Plan Submittal Checklist covering site plan, mounting, one-line diagram, and equipment spec sheets.
