Full Breakdown
King County Code section 21A.30.080 lists home occupation uses that exceed the scope allowed in a residence and bars them outright in the R, UR, NB, CB, and RB zones: automobile, truck, and heavy equipment repair, and auto body work or painting. A resident wanting to fix cars for pay at a house in one of these zones cannot register it as a home occupation and must instead seek a home industry permit under K.C.C. 21A.30.090, if the site qualifies, or locate the business in a zone that allows auto repair outright.
Violations & Fines
King County's Code Enforcement Section can order abatement and impose civil penalties under K.C.C. Title 23 for operating a prohibited home occupation without approval.
