Seattle requires building permits for solar panel installations under SMC Title 22, but has streamlined the process with expedited review for standard residential rooftop systems to encourage renewable energy adoption.
Residential rooftop solar installations require a building permit and electrical permit from SDCI. Standard flush-mounted rooftop systems on single-family homes qualify for expedited over-the-counter permit review, typically processed in one visit. Ground-mounted solar arrays and systems on commercial buildings require standard plan review. Solar panels that do not extend more than 4 feet above the roof surface are exempt from height limit calculations. Solar installations do not count against lot coverage limits under the land use code. Washington state requires utilities to offer net metering for systems up to 100 kW, and Seattle City Light provides favorable net metering rates. The city's Green Building Standard encourages solar-ready construction for new buildings.
Installing solar panels without required permits can result in fines and required removal or modification. Unpermitted electrical work poses safety hazards and may void homeowner insurance coverage. The city may require retroactive permitting and inspection.
