Washington's Residential Landlord-Tenant Act sets the notice a tenant gives to end a month-to-month tenancy. Under RCW 59.18.200, the tenancy ends by written notice of 20 days or more, given by the tenant to the landlord. The notice comes before the end of any month or period of the tenancy. The same rule covers a tenancy that runs from period to period with rent payable each period.[1]
Such tenancy shall be construed to be a tenancy from month to month, or from period to period on which rent is payable, and shall end by written notice of 20 days or more, preceding the end of any of the months or periods of tenancy, given by the tenant to the landlord.
A lease agreement starts a tenancy and a termination letter ends it. For the lease itself, see our Washington rental lease agreement forms or the full list of lease agreement forms.
The FormsPal Washington lease termination letter is a one-page Notice to Terminate Tenancy. It tells the tenants that their tenancy ends on a stated date and that they must give up possession of the premises on that day. It also says that eviction proceedings may follow if they do not.

Delivering the letter is a separate step from filling it out. After the landlord signs the notice, make a copy and get the original to the tenants in a way you can prove later. The steps below are common practice for any written notice.

A tenant in a month-to-month tenancy ends it by written notice of 20 days or more, given to the landlord before the end of a month or rental period. The same rule covers a tenancy that runs from period to period with rent payable each period.[1]
For a month-to-month tenancy, yes. The tenancy ends by a written notice of 20 days or more, so a spoken notice does not meet the rule. Give the landlord the notice early enough that the 20 days end on or before the last day of the month or period.[1]
