Short-Term Rental Regulations
in King County, WA

Airbnbs are effectively legal in King County, WA because there are no specific short-term rental regulations on the books. State law (RCW 64.37) requires operators to provide guest contact info, post emergency contacts and floor plans, comply with CO alarm rules, and maintain $1,000,000 liability insurance. Incorporated cities within the county, such as Seattle, impose additional local zoning limits, unit caps (typically two units), and primary residency requirements. Operators should still verify HOA rules, state-level requirements, and any tax-collection obligations. See the official source linked on this page for full requirements. Last verified 2026-05-14.
