OAR 918-050-0180: Statewide Methodology for Solar Structural Installation Permits

(1) Structural permits for solar photovoltaic (PV) system installation shall be calculated using the following methodology: (a) Fees for installations that comply with the prescriptive installation path described in the state building code shall be a flat fee and includes one inspection and permit review by the municipality. (b)(A) All other installations not meeting the prescriptive path shall be based on the valuation of the structural elements for the solar panels, including racking, mounting elements, rails, and the cost of labor to install. The cost of the solar electrical equipment, including collector panels, and inverters shall be excluded from the structural permit valuation. The valuation shall then be applied to the municipality’s fee schedule to determine the permit fee. (B) Plan review fees shall be based on a predetermined percentage of the permit fee set by the municipality. (2) Electrical components of a PV system require an electrical permit. Electrical permits shall be calculated based on the methodology established in OAR 918-309-0020 through 918-309-0070.
