What belongs in a King County roofing plan?
The county map and Parcel Viewer help identify jurisdiction and site conditions. The exemption is specific to detached one- and two-family homes and is not stated for commercial or multifamily buildings. Listed critical areas may defeat the exemption or require another review, so check the parcel first.
