Washington's largest city and a major Pacific Northwest rental market, home to a substantial multifamily rental housing stock alongside single-family rentals.
Seattle landlords are governed by Washington state law; some cities also add local ordinances beyond the state baseline. The summary below is Washington state law — a general starting point, not legal advice — and doesn't capture any Seattle-specific ordinances. Verify current rules, including any local ordinances, with an attorney before relying on this for an actual tenancy.
Seattle is one of the more heavily regulated rental markets in the country at the city level, on top of Washington state law. Landlords must register rental units under the city's Rental Registration and Inspection Ordinance (RRIO), and Seattle's Just Cause Eviction Ordinance restricts ending a tenancy to a defined list of allowed reasons — a materially stricter standard than Washington state law alone provides. Landlords with Seattle properties should treat the city ordinances as a required layer on top of the state summary below, not a substitute for it.
