Fee schedule
Solar PermitWashington City's Solar Permit Submittal Requirements page (washingtonutah.gov/development/building/solarpermitrequirements, re-verified 2026-07-19; formerly hosted at washingtoncity.org, which now 301-redirects to the same page on the washingtonutah.gov domain) requires a 'Valuation' field correlated to the RRA project cost, but does not publish a separate flat solar-specific fee — assessed on the same Building Permit Fee Table as other permit types. This is a grounded valuation-based fee, not an estimate.

Washington City Building Department page explicitly updated 'MAY 7 2025 UPDATE OF ADOPTED CODES BY THE STATE OF UTAH: 2023 NEC code update' (superseding the previously listed 2020 NEC, still shown struck-through/superseded on the live page as of 2026-07-16); this is one of the few Washington County-area jurisdiction pages independently confirmed current on the electrical code edition, not just inferred from state law; 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).
