Solar PV Permit in Unincorporated Wasatch County, Utah

Required for solar photovoltaic installations in unincorporated Wasatch County. Wasatch County Code § 16.21.42 (Supplementary Development Standards for solar panels) gives solar installations a genuinely distinct zoning treatment depending on mounting type: flush-mounted roof panels are a permitted use in any zone; 'structured' (non-flush, tilted) roof panels are a CONDITIONAL USE in any zone, requiring Planning Commission approval; freestanding (ground-mounted) panels are a permitted use in residential districts only, subject to height, maximum-area, and setback requirements. A building permit is required for installation regardless of mounting type. Wasatch County's own Building Department pages (municipalcodeonline.com hosts the ordinance on a client-side-rendered platform that returns no readable body text to automated fetch tools) do not publish a distinct solar-specific building-permit fee — the general per-square-foot Building Department fee mechanism documented for this jurisdiction's residential-building-permit entry applies. Re-chased 2026-07-20: the county's live Application Fee Schedule (Wasatch County Code 4.09.02 C, effective 7/2025) publishes an exact Conditional Use Permit fee of $700.00 + costs, which is the fee that governs the § 16.21.42 CUP requirement for 'structured' roof-mounted arrays.

Fee schedule

Building Permit Fee — Building Department (general, all mounting types)Wasatch County's own live Frequently Asked Questions page (wasatchcounty.gov/215/Frequently-Asked-Questions and wasatchcounty.gov/frequently-asked-questions), re-fetched directly 2026-07-20: 'Permit fees are based on square footage and vary from project to project. As of June 13, 2016, the average cost for the Building Department portion of the permit is around $1.25 per sq. ft. This includes all square footage, finished, unfinished, garage, and porches and decks.' Though the underlying figure is dated June 2016, the county's own website still actively publishes it as current guidance as of this 2026-07-20 re-fetch — no newer figure has superseded it anywhere on wasatchcounty.gov. No distinct solar valuation table exists; this general mechanism governs the building-permit component of a solar installation the same as it does for any other structure.
approximately $1.25 per square foot (all finished, unfinished, garage, porch, and deck square footage)
County Impact FeeSame live-refetched FAQ page, 2026-07-20. This impact fee applies to new single-family residence construction (connecting to county services); it is unlikely to apply to a stand-alone solar retrofit on an already-connected, existing dwelling, but the FAQ page does not state an explicit solar/retrofit exemption — confirm applicability for your specific project with the Building Department, (435) 657-3200.
$3,085.00 for new single-family residences
Conditional Use Permit Fee ('structured'/non-flush roof panels, or any freestanding installation requiring CUP review)Wasatch County Application Fee Schedule, fetched directly 2026-07-20 (wasatchcounty.gov/DocumentCenter/View/246/Application-Fee-Schedule-PDF, footer-dated 'Wasatch County Code 4.09.02 C - 7/2025'): 'Conditional Use Permit $700 + Costs (Costs include $0.50 per letter, any Engineering Review expenses or legal noticing).' This is the Planning Department's standard, county-wide Conditional Use Permit fee — not solar-specific in the schedule's own text, but it is the exact fee that governs the § 16.21.42 Conditional Use requirement for 'structured' (non-flush) roof-mounted solar arrays.
$700.00 + costs (costs include $0.50 per notice letter, any Engineering Review expenses, or legal noticing)

Tips

  • Mounting type matters in Wasatch County: flush-mounted roof panels are a permitted use requiring only a building permit, but 'structured' (tilted, non-flush) roof panels are a Conditional Use requiring Planning Commission approval in addition to the building permit — confirm which category your installation falls into before applying.
  • Freestanding (ground-mounted) solar arrays are only a permitted use in residential districts, and must meet height, maximum-area, and setback standards under Wasatch County Code § 16.21.42 — contact the Planning Department, (435) 657-3205, to confirm your parcel's zone and the applicable numeric standards, which could not be independently rendered from the county's client-side ordinance platform.
  • No solar-specific building-permit fee table is published; the general ~$1.25/sq ft Building Department fee (still the county's own live-published figure as of a 2026-07-20 re-check, though originally dated June 2016) applies to the building-permit portion of a solar project, and a $700 + costs Conditional Use Permit fee (Wasatch County Code 4.09.02 C, effective 7/2025) applies if your installation is 'structured' (non-flush) roof-mounted and therefore triggers the § 16.21.42 CUP requirement — confirm directly with the Building Department, (435) 657-3200, and the Planning Department, (435) 657-3205.
