San Ramon, CA Solar Energy: Expedited Solar Permitting (2026)

5), aiming for fast, low-cost residential solar installations. Section C8-3 makes the chapter applicable to all small residential rooftop solar energy systems in the city; systems already permitted before the ordinance took effect are grandfathered unless physically altered enough to require new permitting. A 'small residential rooftop solar energy system' is capped at 10 kilowatts AC nameplate rating or 30 kilowatts thermal, must meet state fire, structural and electrical codes, and must sit on a single- or two-family dwelling without exceeding the city's maximum building height.

Under § C8-6, the chief building official runs an administrative, nondiscretionary review: once an application meets the adopted checklist and standard plan, the building and safety services division must issue the building permit. Only if the official finds, based on substantial evidence, that the system would cause a 'specific, adverse impact' on public health or safety can the zoning administrator require a minor use permit under Zoning Ordinance § D6-28; that denial must include written findings on why no feasible mitigation exists, and it can be appealed to the city planning commission.

Any imposed condition must mitigate the impact at the lowest possible cost, measured against Civil Code § 714. Only one inspection is required for systems eligible for expedited review, though a failed inspection triggers a follow-up. An incomplete application draws a written correction notice listing every missing item so the applicant can resubmit under the same expedited track.
