In Seattle, a landlord can end a month-to-month lease only for one of the 18 reasons listed in the Just Cause Eviction Ordinance. Landlords must give notice in writing to end a tenancy. They are required to give most notices to tenants at least 20 days before the end of a rent period, typically the end of the month.
The Just Cause Eviction Ordinance does not regulate lease contracts that end on a specific date.
A notice to end a tenancy is only the first step in the process to evict a tenant for cause under state law. This eviction process starts with a notice to end the tenancy, but it is a separate legal action under Washington state law that can result in a court order requiring a tenant to leave. We can evaluate a notice to see whether it is legal under the Just Cause Eviction Ordinance, a City of Seattle law. However, we are not involved in the eviction process, which is brought under state law.
Regulations relating to the Just Cause Eviction Ordinance are in the Seattle Municipal Code (SMC) and Washington state law (RCW).
