Do I need a permit for solar panel installation in Gilroy?
Yes. In California, solar panel installation generally requires a permit, and Gilroy is no exception.
Cities and counties must approve solar energy systems administratively through a building permit or similar nondiscretionary permit, with review limited to health and safety, and may not condition approval on HOA approval (Government Code 65850.5(b) and (i)). Every city and county must have an expedited permitting process and checklist for small residential rooftop systems, meaning up to 10 kW AC or 30 kW thermal on a single-family or duplex dwelling, and only one inspection is required for an eligible system (Government Code 65850.5(g) and (h)). Unless exempt (cities under 5,000 people, and counties under 150,000 people together with every city in them), a city or county must offer an online automated permitting platform such as SolarAPP+ that issues permits in real time to licensed contractors for residential solar up to 38.4 kW AC and paired storage (Government Code 65850.52). The electrical portion of a PV system must follow the California Electrical Code, and rooftop arrays must have the same fire classification as the roof (CRC R329.3 and R329.4.2).
