Seattle FAQ
Can I evict a 35-day Airbnb guest by changing locks?
No. After 30 days the guest is a tenant under RCW 59.18. You must serve proper notice and obtain an unlawful detainer judgment from superior court.
Should I cap stays at 28 nights?
Many King County operators do exactly that to avoid tenancy formation. If you allow a 30-day stay, sign a written month-to-month lease at that point.
