Mountain View, CA Solar Energy: Panel Permits (2026)

Sec. 05 adopts an expedited permitting process for small residential rooftop solar systems to comply with Civil Code Sec. 714 and Government Code Sec. 5 (AB 2188, 2014). Sec. 15 defines a qualifying "small residential rooftop solar energy system" as one no larger than 10 kilowatts AC nameplate rating, or 30 kilowatts thermal, that conforms to the state fire, structural and electrical codes the city has adopted, is installed on a single-family or duplex dwelling, and does not exceed the maximum legal building height set in City Code Sec.

50. Sec. 20 requires every solar system to meet applicable state and city health and safety standards; water-heating systems must be certified by an accredited listing agency, electricity-producing systems must meet California Electrical Code and Underwriters Laboratories standards, and only qualified persons may perform the installation and wiring. Sec. 25 requires the chief building official to publish an expedited checklist matching the state's Solar Permitting Guidebook, and applicants must submit electronically along with any required fee, which Sec. 30 sets through the city's master fee schedule.

Sec. 35 sets the enforceable timeline: a complete application meeting code must be approved and all permits issued within three business days, and only one inspection is required, which may combine the building and fire inspections. The chief building official cannot condition approval on a homeowners association's approval under Civil Code Sec. 4080, and can deny the application only with written findings of a specific, unavoidable adverse health or safety impact; a denial can be appealed to the city council. City approval does not by itself authorize connecting the system to the utility grid; the applicant must separately get the utility's permission.
