How much notice a tenant and a landlord must give to end a month-to-month tenancy in Washington, and the statute that controls — verified July 2026.
Tenant: At least 20 days before the end of any monthly/periodic period.
Landlord: Just cause required — a landlord generally CANNOT end a month-to-month without a statutory cause; notice varies by cause (commonly 60 days; 90 days for owner move-in/sale). The 2021 just-cause law eliminated no-cause 20-day terminations by landlords; wrongful eviction exposes the landlord to 3x monthly rent plus fees.
