King County itself imposes no primary-residence restriction on short-term rentals in unincorporated areas, but several cities within the county, most notably Seattle, limit operators to their primary dwelling plus at most one additional unit.
Seattle Municipal Code 6.600 caps STR operators at two units total: a primary residence and one secondary dwelling, each requiring a separate operator's license. Bellevue, Redmond, and Kirkland have studied similar caps but as of 2026 enforce only registration and lodging-tax collection. Unincorporated King County imposes no primary-residence test; rural cabins, ADUs, and second homes may all be listed. Hosts should verify city of jurisdiction before listing because city limits do not always track ZIP codes, and a Seattle mailing address may sit outside Seattle city limits.
Seattle operators exceeding two-unit cap face license revocation, daily fines, and platform takedown. Unincorporated hosts face no primary-residence penalty but must comply with state RCW 64.37 obligations.
