Downey provides expedited permitting for small residential rooftop solar per AB 2188 and the Solar Rights Act. Systems up to 10 kW AC qualify for streamlined review. Panels cannot exceed the maximum building height.
Downey requires a building permit for residential solar panel installations. Most jurisdictions have adopted streamlined or expedited permitting for standard rooftop solar systems. Plans must show panel layout, structural capacity of the roof, electrical interconnection, and setbacks from roof edges. Fire setbacks provide pathways for firefighter access, typically 3 feet from roof ridge and edges. Electrical permits cover the inverter, disconnect, and utility interconnection. Net metering agreements with the local utility allow credited excess generation. Solar access laws in many states protect existing solar installations from new shading by neighboring properties or structures. Ground-mounted systems may face additional zoning setback requirements.
Installation without permit: retroactive permit required plus fines $200 to $1,000. Electrical code violations: correction order. Failure to obtain utility interconnection: system must be disconnected.
