Summary
Riverside County must administratively approve small rooftop solar systems up to 10 kW AC as nondiscretionary permits, with just one inspection, for homes in the unincorporated county: incorporated cities like Riverside and Temecula run their own separate solar permitting.
Applications for small residential rooftop solar energy systems shall be administratively reviewed and approved by the director as nondiscretionary permits within in a reasonable time following receipt of a complete application that meets the requirements of the county's approved checklists, standards plans, and payment of all required permit processing and inspection fees.

Full Breakdown
Under County Code § 15.96.060, the building and safety department reviews small residential rooftop solar applications administratively and approves them as nondiscretionary permits once the application meets the county's standard checklists and plans and required fees are paid: no hearing or discretionary approval. Only one inspection is required under § 15.96.070. Qualifying systems must be 10 kW AC (or 30 kW thermal) or smaller and installed on a single or duplex dwelling per § 15.96.030. The chapter applies only in the unincorporated county; Riverside, Moreno Valley, Corona, Temecula, Palm Springs and the county's other incorporated cities administer their own municipal solar permitting.
Violations & Fines
Systems exceeding 10 kW AC, or ones the director finds pose a specific, adverse safety impact, lose expedited status and must instead go through discretionary plot-plan review under County Ordinance No. 348, sections 18.30 and 18.51.
