Federal Way uses the Washington State Building Code for rooftop solar. Most residential PV systems need an electrical permit from L and I and a structural review from Federal Way.
Rooftop solar PV in Federal Way is regulated primarily by the Washington State Building Code adopted under RCW 19.27 and the Washington State Electrical Code administered by the Department of Labor and Industries. For a typical home system under about 25 kW, the homeowner or contractor needs an L and I electrical permit and a Federal Way building permit (often handled together as a simple solar permit). Structural engineering verification is required where rafters or trusses carry the added panel load, especially on older homes near Steel Lake and West Campus neighborhoods. Federal Way requires fire-access pathways on the roof per IFC Chapter 12, with setbacks from ridges and hips so firefighters can work. Ground-mount arrays need zoning review for setbacks and lot coverage. Net metering is handled by Puget Sound Energy under RCW 80.60. Interconnection must be inspected before utility tie-in is authorized by PSE.
