Short-term rental permit rules in King County, WA — also called Airbnb permits, vacation rental licenses, or STR registration — list the application steps, fees, and operating requirements for hosting.
Short-term rental operators in unincorporated King County must obtain a Washington State business license from the Department of Revenue and comply with King County zoning under KCC Title 21A. The Permitting Division manages STR regulations for unincorporated areas including White Center, Skyway, Fairwood, and Vashon Island.
To legally operate a short-term rental (fewer than 30 consecutive days) in unincorporated King County, hosts must first obtain a state business license from the Washington Department of Revenue. Additionally, the property must comply with zoning requirements under KCC Title 21A. The King County Permitting Division manages short-term rental regulations and can provide guidance on zoning, occupancy limits, and county-specific requirements. Unincorporated areas include communities such as White Center, Skyway, Fairwood, Fall City, Vashon Island, and rural east King County. Zoning determines whether STRs are permitted on a given property. King County has a fairly strict regulatory environment for short-term rentals, with active enforcement. Operating without proper registration leaves hosts vulnerable to fines and legal action.
Operating without a state business license subjects hosts to Department of Revenue penalties. Zoning violations are enforced by King County Code Enforcement under KCC Title 23.
