In Washington, a landlord must give between 20 and 120 days’ written notice to not renew a lease, and the exact number depends on why the tenancy is ending. For almost every month-to-month tenancy, the landlord also needs a legally recognized “just cause” under RCW 59.18.650. Getting either piece wrong, the reason or the timing, can invalidate the whole termination.
Notice Periods by Reason
Washington assigns longer notice windows to the reasons that are hardest on tenants. Match the landlord’s stated reason to the right row before anything else.
120 Days
A landlord planning to demolish the unit, withdraw it from the rental market to convert it to a condominium, or perform substantial rehabilitation that requires the tenant to move out must give at least 120 days’ written notice.1Washington State Legislature. RCW 59.18.440 – Relocation Assistance for Low-Income Tenants This is the longest window in the statute.
90 Days
Two common landlord-need reasons carry a 90-day requirement. The first is sale of a single-family home. The second is owner or immediate-family move-in, where the owner or family member will use the unit as their primary residence and no equivalent vacant unit is available in the same building.2Washington State Legislature. Washington Code 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy
60 Days
The 60-day notice covers two situations. It applies to the narrow no-cause non-renewals of qualifying fixed-term leases described in the next section. It also applies when the owner lives on-site and intends to sell or substantially rehabilitate a unit in that owner-occupied building.2Washington State Legislature. Washington Code 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy
20 Days
When a tenant shares a kitchen or bathroom with the landlord in the landlord’s own home, 20 days’ written notice is enough.3Washington State Legislature. RCW 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy This shortest window reflects the shared-living arrangement.
When a Landlord Can End a Lease Without Stating a Reason
Washington bars landlords from ending most tenancies simply because they feel like it. Under RCW 59.18.650, a landlord cannot refuse to continue a tenancy or end a periodic tenancy except for reasons specifically listed in the statute.2Washington State Legislature. Washington Code 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy There are two narrow exceptions where a no-cause non-renewal is allowed, both requiring 60 days’ notice:
- An initial written lease of 6 to 12 months that is set to convert into a month-to-month tenancy at the end of the term. The landlord can decline to let it convert with at least 60 days’ advance written notice before the initial period expires.
- Successive fixed-term leases of six months or more that have run continuously since the start of the tenancy without ever lapsing into a month-to-month arrangement. The landlord can end it at the close of a specified term with at least 60 days’ written notice.2Washington State Legislature. Washington Code 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy
Once a tenancy becomes month-to-month at any point, the no-cause window closes for good. From then on, every termination needs a just cause reason. If a lease expired and nobody signed a new one, the tenant is month-to-month, and the full just cause protections apply.
What the Notice Must Say
The notice has to be in writing. Verbal conversations, text messages, and casual emails don’t count. It must identify the specific just cause reason and include enough supporting facts for the tenant to understand why they are being asked to leave.3Washington State Legislature. RCW 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy A notice that just says “your lease is not being renewed,” with no reason from the statute, is not valid for any tenancy protected by just cause.
The notice also has to state the exact date the tenancy ends. For an owner move-in, it should name who plans to occupy the unit. Vague language invites a successful challenge later.
How the Notice Must Be Delivered
Service follows RCW 59.12.040, which sets a specific order. The landlord’s first option is to hand the notice directly to the tenant. If the tenant is not available, the landlord can leave it with another person of suitable age at the residence and mail an additional copy. Only if nobody is home may the landlord post the notice in a visible spot on the property and mail a copy.2Washington State Legislature. Washington Code 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy
Skipping steps matters. A landlord who jumps straight to taping a notice on the door without first attempting personal delivery has not properly served it, and a court can throw out the termination on that basis alone.4Washington Courts. Eviction Resolution Program Forms Packet
Retaliation and Bad-Faith Limits
Even a properly worded and properly timed notice can fail if the underlying reason isn’t genuine. Under RCW 59.18.240, a landlord cannot evict, raise rent, reduce services, or refuse to renew as payback against a tenant who reports code violations, requests legally required repairs, joins a tenant organization, or participates in a court or administrative proceeding about the property.5Washington State Legislature. RCW 59.18.240 – Reprisals or Retaliatory Actions by Landlord, Prohibited If a termination notice arrives within 90 days of any of those protected activities, a court presumes the termination is retaliatory, and the landlord carries the burden of proving otherwise.6Washington State Legislature. RCW 59.18.250 – Reprisals or Retaliatory Actions by Landlord, Remedies
The statute also polices bad-faith use of sale as a stated reason. The owner must make reasonable attempts to sell the property within 30 days after the tenant moves out, including listing it at a reasonable price with a real estate agency or on the multiple listing service. If the owner fails to do that, or within 90 days pulls the property off the market or rents it to someone else, the law creates a rebuttable presumption that the termination was made in bad faith.2Washington State Legislature. Washington Code 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy, End of Periodic Tenancy
What To Do After Receiving a Non-Renewal Notice
Read the notice carefully before doing anything else. Check three things: the stated reason matches one of the just causes in the statute, the notice period is long enough for that particular reason, and the notice was delivered through one of the legally required methods. A defect in any of those elements can be raised as a defense if the landlord later files an eviction case.4Washington Courts. Eviction Resolution Program Forms Packet
If you spot a problem, put it in writing. A letter or email pointing out the specific defect creates a record and sometimes prompts the landlord to withdraw or fix the notice. If the timing suggests retaliation, document when you filed your complaint or repair request and when the notice arrived. That 90-day presumption window is your strongest tool.
If the notice looks valid, start planning your move. Vacating by the stated date avoids an unlawful detainer lawsuit, which is Washington’s formal eviction process and creates a court record that can make renting harder later. Leaving the unit in good condition also helps ensure you get your full security deposit back.
Local Ordinances May Require More
Several Washington cities add tenant protections on top of state law. Seattle has its own just cause ordinance with 16 recognized reasons for termination, some of which require the landlord to go through a city relocation license process that can take roughly six months, and Seattle requires relocation assistance in certain termination types.7City of Seattle. Just Cause Eviction Ordinance Tacoma and other cities have similar local rules. Before relying on the state notice periods alone, check with your local housing office, because the strongest protections available to you may come from a municipal code.
