RCW 35.21.830 — Controls on rent for residential structures — Prohibited — Exceptions. The imposition of controls on rent is of statewide significance and is preempted by the state. No city or town of any class may enact, maintain, or enforce ordinances or other provisions which regulate the amount of rent to be charged for single-family or multiple-unit residential rental structures or sites other than properties in public ownership, under public management, or properties providing low-income rental housing under joint public-private agreements for the financing or provision of such low-income rental housing. This section shall not be construed as prohibiting any city or town from entering into agreements with private persons which regulate or control the amount of rent to be charged for rental properties. [1981 c 75 s 1.] Notes: Applicability to floating home moorage sites — 1981 c 75: "Nothing in this act shall be construed to preempt local ordinances that relate to the control of rents or other relationships at floating home moorage sites."
Full Breakdown
Washington's statewide preemption law (RCW 35.21.830) prohibits cities from imposing rent control or stabilization measures. Seattle cannot cap rent increases or limit how much landlords may raise rents. However, the city has adopted related tenant protections. Under SMC 22.206.180, landlords of certain low-income housing must provide 180-day notice before rent increases of 10 percent or more and provide tenant relocation assistance. The city requires 60-day written notice for any rent increase (exceeding state minimums in some cases). Seattle's tenant protection ordinances also include requirements for landlords to offer existing tenants the first right to lease renewal. The city has explored various rent stabilization proposals but remains legally constrained by state preemption.
Violations & Fines
Landlords who fail to provide required notice periods for rent increases may face penalties under the Housing and Building Maintenance Code. Failure to provide relocation assistance when required can result in fines and tenant claims for damages.
