Eastvale, CA Solar Energy: Expedited Solar Permitting (2026)

Eastvale Municipal Code § 110.44.060 requires the building department to run "an administrative, nondiscretionary review process" for small residential rooftop solar systems and states that when an application meets the approved checklist and standard plan, the department "shall issue a building permit or other non-discretionary permit within three business days." The chapter, adopted by Ordinance No. 15-06 to implement the state's Solar Rights Act and AB 2188, covers systems no larger than 10 kilowatts AC (or 30 kilowatts thermal) installed on a single-family or duplex dwelling and not exceeding the city's maximum building height.

Review is limited to whether the applicant meets local, state, and federal health and safety requirements; the building official cannot second-guess design choices beyond that. A use permit can be required only if the official finds, based on substantial evidence, a specific, adverse impact on public health and safety, and any denial must include written findings on why no feasible mitigation exists, with appeal rights to the planning commission under § 120.01.040. Only one inspection is required for systems that qualify for expedited review, that inspection must be scheduled within two business days of a request, and the city cannot condition approval on a homeowners association's sign-off, per Civil Code § 4080. If an application is incomplete, the building department must send a written correction notice detailing every deficiency rather than simply denying it.
