Washington State has a state law that applies to rental housing called the Residential Landlord-Tenant Act (RCW 59.18). However, many housing providers in Washington also have to deal with a patchwork of city and county laws that add complexity on top of the state law. Many cities in Washington require housing providers to register their rental units with the city. Some cities and counties have passed their own rental housing ordinances that act on top of the WA RLTA.
