City of Napa provides expedited permitting for small residential rooftop solar under California's Solar Rights Act (Civil Code §714) and AB 2188 (Gov Code §65850.5). Eligible systems (10 kW PV or 30 kWth solar water heating) receive streamlined ministerial approval. HOA restrictions are limited by state law.
California's Solar Rights Act (Civil Code §714) bars HOAs and local governments from restrictions that significantly raise cost or reduce solar efficiency. AB 2188 amended Gov Code §65850.5 to require every California city to adopt an expedited, streamlined permit process for small residential rooftop solar (10 kW PV or 30 kWth). Napa's Building Division administers expedited solar permits with an online checklist and standardized plans. Installations must comply with California Electrical Code Article 690, California Building Code roof loading, and California Fire Code §1204 access pathways. Battery storage and ground-mounted arrays do not qualify for AB 2188 expedited review. Title 24 mandates PV on most new single-family homes since 2020. PG&E handles net metering interconnection.
Installing solar without any permit violates the California Building Code; the city can require the system de-energized until permitted. Cities failing expedited review may be challenged under AB 2188. HOAs blocking compliant solar face civil suit under Civil Code §714.
