Summary

Installing rooftop solar panels on a home in unincorporated Pierce County requires a building permit under PCC 17C.10.070, and the fee scales with system size: a base fee plus an added charge that roughly doubles once the array exceeds 5 kilowatts. Skipping the permit exposes the installer to the same misdemeanor and civil-penalty enforcement that applies to any unpermitted building work.

City-specific rules exist: Tacoma has its own panel permits rules that differ from Pierce County's county-level regulations. If you live in Tacoma, check the city-specific page instead.
