Solar Roof/Ground Installation Permit in Unincorporated Elmore County, Idaho

Required for installation of rooftop or ground-mount solar photovoltaic systems in unincorporated Elmore County. Elmore County publishes a distinct FLAT fee for solar installations — 'Solar Roof/Ground Installation' — separate from the valuation-based building permit fee table used for general construction, per the County's own Land Use and Building Department Fee Schedule. All applications must be preceded by a Zoning Permit. Electrical interconnection work is not addressed on the County's own Building Permit Requirements page; no county electrical-permit type is published by the Land Use and Building Department, consistent with the pattern in every other Idaho county in this database (except Bonneville, effective Jan. 2026) where electrical work is routed to the State of Idaho DOPL/Division of Building Safety rather than the county.

  • Zoning Permit must precede the building permit application, with no exceptions
  • A detailed site plan is required showing property lines, existing structures, easements, and the exact dimensions of the proposed solar installation

Tips

  • Elmore County is one of the few counties in this database with a genuine flat, distinct solar permit fee — $100 plus a $50 deposit — rather than billing solar under the general valuation-based building permit table.
  • Don't skip the Zoning Permit step: the County states it must precede the building permit application for ALL projects, with no exceptions, and a detailed site plan is required for nearly all solar applications.
