Full Breakdown
King County Code Section 21A.08.050 places Veterinary Clinic in its personal-services land-use table. It is permitted outright only in the Office zone, conditional in the Rural Area and R-1 zones, and not allowed at all in the Forest, R-4-R-8, Regional Business or Industrial zones. In the Agricultural, Mineral and Urban Reserve zones it is allowed only as a home occupation: boarding or overnight stay of animals requires five acres or more, no burning of refuse or dead animals is allowed, and any room where animals are kept or treated must be soundproofed with an eight-foot solid wall around outdoor runs. This is unincorporated-area code only; Seattle, Bellevue, Kent, Renton and other cities regulate veterinary clinics under their own municipal codes.
Violations & Fines
Operating a veterinary clinic without the required conditional-use approval, or outside the home-occupation limits, is a King County zoning code violation; the Department of Local Services can issue a notice of violation, order corrective action, and impose civil penalties.
