Seattle has some of the nation's most detailed requirements for notices, including lease renewals, rent increases, and ending a tenancy, so staying informed is important. Whether you're increasing rent, entering a rental property, or deciding not to renew a lease, the timing, language, and delivery of each notice matter. Following the correct process helps protect both landlords and residents while reducing the risk of legal disputes or unenforceable notices.
Seattle's Just Cause Eviction Ordinance limits the circumstances under which landlords can end a tenancy or refuse to renew a lease. Unlike many jurisdictions, landlords cannot terminate a tenancy without a legally recognized reason.
The ordinance, first passed in 1980, applies to month-to-month renters, renters with verbal agreements, and renters with expiring term leases. To end or decline to renew one of these tenancies, a landlord or property manager must state one of the specific approved reasons listed in the ordinance and comply with the Rental Registration and Inspection Ordinance.
Examples of just cause may include nonpayment of rent, significant lease violations, owner move-in, or substantial rehabilitation of the property. Each reason has its own legal requirements, documentation standards, and notice obligations. Because the rules vary by circumstance, landlords should understand the applicable requirements before taking action.
How Much Notice Is Required for a Rent Increase in Seattle?
Seattle requires landlords to provide at least 180 days' written notice before a rent increase takes effect, as of November 8, 2021. This requirement exceeds Washington State law and gives residents additional time to prepare for changes in housing costs.
Separately, Washington now limits how much rent can increase. Under the state's rent stabilization law (HB 1217, effective 2025), most residential rent increases are capped at the lesser of 7% plus the annual Consumer Price Index or 10% within any 12 months, and no increase is permitted during the first 12 months of a tenancy. The maximum allowable increase for 2026 is 9.683%. This percentage is recalculated each year, and some properties may be exempt, so landlords should confirm the current limit and whether it applies to their property before issuing an increase. This statewide cap applies in addition to Seattle's 180-day notice requirement — a landlord must stay within the allowable amount and give proper notice.
In some situations, a significant rent increase may also trigger Seattle's Economic Displacement Relocation Assistance (EDRA) program, which can require relocation assistance for eligible households that meet the program's income and eligibility requirements. According to the City of Seattle, “Beginning July 1, 2022, when your landlord increases your housing costs by 10% or more within the same 12-month period, you may be eligible for Economic Displacement Relocation Assistance - EDRA.”
What Other Notice Requirements Should Landlords Know About?
Issuing Notices Correctly Matters
Seattle has detailed requirements governing when notices must be provided, what information they must include, and how they must be delivered. For example, the law states that, “You must attempt to personally serve your tenant notices that terminate a tenancy, offer a lease renewal, increase housing costs, or materially change terms of the rental agreement. If your tenant is not available, you must then post the notice conspicuously (on their front door) and mail it by first-class mail. Allow an additional 5 days for the mail to get to the tenant before the notice period expires as per RCW 59.12.040.”
Additionally, certain types of notices require specific language, and eviction notices require additional required language.
Whether you're increasing rent, addressing a lease violation, or ending a tenancy, following the correct process is just as important as having a valid reason for issuing the notice. Using the wrong notice, missing a required deadline, or failing to follow Seattle's delivery requirements can invalidate the notice and delay the process. Before taking action, landlords should confirm they are using the appropriate notice and following all applicable federal, state, and local requirements.
Notice Requirements for Entering a Rental Property
Seattle law protects a resident's right to privacy while allowing landlords to access a rental property for legally permitted reasons. Landlords may enter an occupied unit to make necessary repairs or improvements, provide agreed-upon services, conduct inspections, or show the property to prospective tenants or buyers. Except in emergencies or when a rental property has been abandoned, landlords must provide proper written notice before entering and obtain the resident's consent.
The required notice depends on the reason for entry. Landlords must provide at least two days' written notice before entering to make repairs or improvements, supply services, or conduct an inspection. When entering to show the property to prospective tenants or buyers, landlords must provide at least one day's written notice.
Seattle also requires entry notices to include the purpose of the entry, the proposed date and time, and the name and phone number of a person the resident can contact to request a different time. In return, residents are required to provide reasonable access to the property owner or property manager. Following these requirements helps landlords meet their legal responsibilities while respecting resident privacy and minimizing potential disputes.
