Full Breakdown
Unincorporated King County limits home-business customer traffic under K.C.C. 21A.30.080, governing home occupations in the R, UR, NB, CB, and RB zones. Customer visits and deliveries are confined to 8:00 a.m.-7:00 p.m. weekdays and 9:00 a.m.-5:00 p.m. weekends, and the home occupation cannot raise average vehicular traffic by more than four additional vehicles at any given time, measured at the lot line. The same visit-hour restriction applies in the Agricultural, Forest, and Rural zones under the parallel K.C.C. 21A.30.085.I. Seattle, Bellevue, Kent, Renton, and the county's other incorporated cities set their own home-business rules under their own municipal codes, not this county code.
Violations & Fines
The King County Department of Local Services, Permitting Division, enforces home occupation standards; exceeding the visit hours or traffic cap can draw code enforcement action, a stop-work or correction notice, or permit revocation.
