Solar Photovoltaic (PV) Installation Permit in Unincorporated Summit County, Utah

Unincorporated Summit County requires a Building Permit for solar PV installations, per the County Building Department's official page: 'Permits are also required for solar PV installations.' Unlike the general residential/commercial Building Permit (which is priced off the ICC Building Valuation Data table and a non-public multiplier), the County's own Building Department Fee Schedule (Ordinance 834-P) prices solar PV under a distinct 'Alternative Energy Permits' category — explicitly described in the ordinance as 'separate from the permits issued for new construction' — with a flat $700 Photovoltaic System fee. Applications are still submitted through the same EPROCESS360 online portal as all other County building permits; no standalone solar-only application form, checklist, or fee schedule document is currently published (the County's historical 'Solar ABCs' expedited-permitting checklist, once posted at DocumentCenter View 272, is now a dead link with no Wayback capture, confirmed by this verification).

When you need this permit

  • A County Building Permit is required for solar PV installations (residential or commercial) in unincorporated Summit County, per the Building Department's official page
  • Application is submitted through the EPROCESS360 online portal (summit.co.ut.eprocess360.com) — the County does not accept paper plans or perform over-the-counter reviews, and no distinct solar-only application form is published
  • Electrical interconnection work must comply with the 2023 National Electrical Code (NEC), adopted statewide per Utah Code § 15A-2-103(1)(g)
  • For roof-mounted arrays, standard structural attachment/point-load documentation may be requested during plan review, consistent with the County's general Construction Plans requirements for structural elements (no solar-specific structural checklist is separately published)
  • Confirm with the Building Department at (435) 336-3124 whether a given project (e.g., ground-mounted array, battery storage addition) needs additional planning/zoning review beyond the building permit

Fee schedule

Alternative Energy Permit — Photovoltaic SystemSummit County Building Department Fee Schedule, Ordinance 834-P (amended May 2026, effective 6/2026), item 4: 'Alternative Energy Permits: These permits are separate from the permits issued for new construction. These permits include, but are not limited to, solar, hot water, photovoltaic, geo-thermal, and wind generated power. a. Photovoltaic System: $700.' Confirmed directly by this verification: the document is a scanned (non-machine-readable) PDF, so it was downloaded and page 33 was rendered to an image and read visually on 2026-07-21 — the $700 Photovoltaic System line is explicitly distinct from the general 0.0075-of-valuation Building Permit Fee used for new construction.
$700 flat fee
Plan Review FeeSummit County Building Department Fee Schedule, Ordinance 834-P, item 3. The ordinance does not clarify whether this 65% add-on applies on top of the flat $700 Alternative Energy Permit fee or only to the valuation-based Building Permit Fee in item 2 — confirm with the Building Department before budgeting.
65% of the applicable building permit fee (may be waived if plan review is not necessary, per the Building Official)
Utah State SurchargeSummit County Building Department Fee Schedule, Ordinance 834-P, item 9, collected and remitted to the State of Utah per UCA 15A-1-209 — stated to apply to 'all permits,' so this applies to the Alternative Energy Permit fee as well.

Inspection process

  1. 1

    Electrical / PV Interconnection Inspection

    Not separately published as a distinct solar-specific inspection sequence by the County; follows the standard electrical inspection practice documented for this jurisdiction's residential-building-permit entry (e.g., minimum two 20-amp GFCI-protected circuits required for power-to-panel work, per the County's 4-Way Inspection description).

  2. 2

    Final

    Final inspection sign-off for the PV system installation.

Tips

  • Solar PV is one of the few permit types in unincorporated Summit County with a published flat fee — $700 for a Photovoltaic System — rather than the opaque valuation-based formula used for general new construction. Compare to the schedule's other Alternative Energy Permit line items: Geo-Thermal $500, Solar Hot Water $250, Wind Generator $250.
  • The ordinance describes Alternative Energy Permits as 'separate from the permits issued for new construction' — this is the applicable fee track for standalone solar/PV installations (e.g., retrofits onto an existing home), rather than folding solar into the whole-structure ICC valuation calculation used for new-build permits.
  • No dedicated solar-only application form or checklist is currently published; applications go through the same EPROCESS360 portal and general Building Permit Checklists as every other permit type in this jurisdiction.
  • A historical County document referencing an expedited 'Solar ABCs' checklist (Summit County was, with Park City, one of the first two Utah jurisdictions to adopt this streamlined model, per Utah Clean Energy's Solar Permitting Toolbox) is no longer reachable (DocumentCenter View 272 returns a 404, no Wayback capture found) — confirm current solar-specific submittal expectations with the Building Department at (435) 336-3124 or buildingquestions@summitcountyutah.gov.
  • It is unclear from the ordinance text whether the 65% Plan Review Fee add-on applies on top of the flat $700 Photovoltaic fee, or only to the general valuation-based Building Permit Fee — the 1% Utah State Surcharge is explicitly stated to apply to 'all permits' and so does apply here.
