Notes

Rent increases need 90 days' written notice since 7 May 2025 (HB 1217), which also caps most annual increases. A landlord may end a tenancy only for one of the causes listed in RCW 59.18.650, each with its own notice, so no single period is published; a tenant ends a month-to-month tenancy with 20 days' notice before the end of a month. Entry: 2 days. Late rent: 14-day pay-or-vacate.

Seayora computes the notice this rule requires from the tenancy’s own dates — for a renewal offer, a rent increase or a served notice — and will not serve one that is short unless the owner records a reason. The answer above is the rule the product enforces.
