Yes, in Washington, a landlord generally cannot evict a tenant for no reason. If the tenant has a fixed-term lease agreement, the landlord must have legal cause (such as nonpayment of rent or a lease violation) to evict before the lease ends.
For tenancies without a lease or month-to-month arrangements, the landlord can typically end the tenancy with proper written notice (often 20–60 days depending on the length of the tenancy), but must still cite a valid legal reason under Washington’s just cause eviction rules.
In all cases, the landlord must obtain a court order and cannot use self-help eviction methods.
