Landlord Tenant

This guide briefly discusses issues related to housing and landlord/tenant laws in Washington State.  If you are interested in the eviction process specifically, see our Eviction Process Guide.   Visit either of the following web sites for definitions of the terms used here:


Landlord Tenant (LT) matters are primarily governed by state law, but county and municipal codes, as well as federal statutes, may affect your issue. You should check each of these sources, including any supplements or pocket parts that incorporate recent changes to the law.


Washington Law Help. The Washington Law Help’s website has lots of self-help material on landlord-tenant issues, eviction, and tenants’ rights.

Tenants Union. The Tenants Union is a Seattle-based organization that provides information on tenant rights and also advocates for tenants.

Tips (formerly known as Client Assistance Memos) are available from the City of Seattle about a variety of landlord/tenant issues. Look in the 600s for Tips specific to housing issues.


The Washington Residential Landlord Tenant Act, found at Revised Code of Washington (RCW) chapter 59.18 imposes strict legal obligations on both parties to a residential lease. The RCW is kept on stack 20B.

County Codes and Municipal Codes may govern your lease. It is important to read the topical index to these codes, as they generally do not have a specific LT section even though they may affect state law. For example, the Seattle Municipal code places the duties of a landlord or tenant under Title 22-Building and Construction Code, while rental agreement regulation is found under Title 7-Consumer Protection. Unfair housing practices are under Title 14-Human Rights.

Federal statutes affect the state LT Act. Potentially applicable laws include the Federal Fair Housing Act (42 USC 3602 et seq.), the Americans With Disabilities Act (42 USC 12101) and the Federal Rehabilitation Act of 1973 (29 USC 701).

Case Law will explain how courts have ruled on issues similar to yours, as well as how the courts interpret particular provisions of statutory law. The secondary sources listed below will direct you to some relevant cases, or you may ask at the desk for a guide to using digests and annotated statutes to find other cases.
