Solar Panel (PV) Permit in Unincorporated Carbon County, Utah

Required for rooftop and ground-mounted solar photovoltaic system installation on unincorporated Carbon County land. Carbon County's Building Permits service page explicitly lists 'Solar Panels' among the project types requiring a building permit, and — effective January 1, 2025 — names 'New Construction and Solar' building permit applications specifically as requiring a non-refundable $250.00 deposit, applied as a credit toward the final permit fee. The county does not publish a dedicated solar submittal checklist distinct from its standard plan-set requirements, and (consistent with the rest of this file) no dollar-amount valuation-based fee table beyond the $250 deposit could be located on carbon.utah.gov after a direct re-check of the Building Permits page.

Tips

  • Carbon County names 'Solar' specifically (alongside 'New Construction') in its $250 non-refundable deposit requirement, effective 1/1/2025 — this is the clearest evidence the county treats solar as a distinct permit category, even though it folds into the same general Building Permit Application and plan-set process rather than a dedicated solar checklist.
  • No dollar-amount valuation-based fee table for the underlying permit fee (beyond the $250 deposit) could be located on carbon.utah.gov as of 2026-07-19 — contact the Building Department at (435) 636-3260 or planning@carbon.utah.gov for a project-specific quote.
  • Unincorporated-area applicants still need a signed Road Encroachment Agreement if access is from a county road, the same as for new home/cabin construction.
