San Mateo provides streamlined solar permitting as required by AB 2188 and SB 1222. Residential rooftop systems meeting standard criteria receive ministerial (non-discretionary) approval. The city processes solar permits within the required 3-business-day timeframe.
Solar panel permits in San Mateo follow the streamlined process mandated by AB 2188 (2014) and SB 1222 (2022). Qualifying residential rooftop systems receive ministerial approval without discretionary review. Standard residential rooftop PV systems under the roof weight limit are eligible for expedited processing. The city must process applications within 3 business days per state law. Applications include a site plan, equipment specifications, and electrical single-line diagram. Inspection is required after installation. The Building Division handles solar permits at 650-522-7200. San Mateo's location in the tech-oriented Peninsula and California's solar mandate for new construction mean solar installations are common and the permitting process is well-established.
Installing without a permit is a building code violation. The process is designed to be fast and affordable per state law.
