Solar / Solar PV Installation Permit in Unincorporated Millard County, Utah

Millard County does not publish a distinct residential or commercial rooftop/building-mounted solar or solar photovoltaic (PV) installation permit, application, or fee. An exhaustive search of the county's Building Inspection Department page, its Forms page, and the county's combined Electrical/Mechanical/Plumbing/Stucco building permit application found no separate solar-specific line item — rooftop/building-mounted solar PV installation is electrical work and is billed under the same general Electrical Permit line item used for all other electrical work ($45.00 residential, $75.00 commercial/pivot), the identical pattern already documented on this file's EV Charger/EVSE Permit entry. This entry covers customer-sited (rooftop or ground-mount, building-connected) solar PV installation only — it is distinct from the large-scale utility solar generation facilities sited in Millard County (e.g., ECG Utah Solar 1, Pavant Solar), which go through the county's separate land-use/zoning Conditional Use Permit process for major solar energy generation facilities, not the building permit process documented in this file.

Tips

  • Millard County does not have a separate solar or solar PV permit — rooftop/building-mounted solar PV installation is treated as standard electrical work, pulled under the $45 residential (or $75 commercial/pivot) Electrical line item on the county's combined Electrical/Mechanical/Plumbing/Stucco permit form, the same treatment already documented for EV charger installations in this file.
  • This is separate from Millard County's large-scale utility solar generation facilities (e.g., ECG Utah Solar 1, Pavant Solar I/II/III) — those go through the county's zoning/land-use Conditional Use Permit process for major solar energy systems, not the building-permit Electrical line item covered by this entry.
  • A re-inspection fee may be charged if the project is not ready for inspection at the time the inspection is ordered, per the permit application form.
  • Confirm utility interconnection requirements (e.g., Rocky Mountain Power net-metering application) separately with the electric utility — this is not administered by Millard County Building Department.
