Landlord-tenant laws in Seattle require rental property owners to comply with both City of Seattle ordinances and Washington State laws. These requirements affect nearly every stage of managing a rental, from tenant screening and property inspections to rent increases, security deposits, and ending a tenancy, including through the eviction process.
Seattle rental laws add requirements such as the Just Cause Eviction Ordinance, RRIO registration and inspections, and additional tenant protections to the statewide rules governing rental housing. Understanding which laws apply, where city and state requirements overlap, and which requirements are stricter can help Seattle rental property owners stay compliant throughout the tenancy.

Washington State landlord-tenant laws establish requirements that apply to rental properties throughout the state, including those in Seattle. The Residential Landlord-Tenant Act (RLTA) addresses areas such as the eviction process, security deposits, habitability, tenant screening, and landlord access to occupied rental properties. Seattle landlords must follow these statewide requirements alongside applicable city ordinances.
Additionally, property owners in Washington need to be aware of:
Washington State eviction law establishes the notices and legal procedures landlords must follow when pursuing an eviction. The specific requirements depend on the reason for ending the tenancy, and landlords must use the appropriate notice and follow applicable service requirements before moving forward with an unlawful detainer action.
For example, when a tenant fails to pay rent, Washington law requires a 14-day notice to pay rent or vacate before an eviction proceeding can begin. Other situations, such as certain lease violations, nuisance, or other legally recognized causes for ending a tenancy, have their own notice periods and requirements.
If the issue is not resolved within the applicable notice period, the landlord can pursue an unlawful detainer action through the court. A landlord cannot bypass the legal process and remove a tenant.
There are requirements for collecting, documenting, and returning security deposits to remain in accordance with Washington State law. Landlords must follow requirements for move-in condition reports, documentation of deductions, and returning the remaining deposit and required statement after the tenancy ends. After the tenancy ends and the tenant vacates, the landlord has 30 days to provide any refund due along with a full and specific statement explaining amounts withheld. Damage deductions must also be supported with required documentation, such as move-out inspection files, estimates, invoices, receipts, or other applicable records.
Landlords must keep rental properties fit for human habitation, including maintaining essential electrical, plumbing, heating, structural, and other systems and completing required property maintenance. After receiving notice of a qualifying repair issue, landlords must begin remedial action within specific timeframes. This includes 24 hours for loss of water, heat, electricity, or imminently hazardous conditions; 72 hours for certain landlord-provided appliances or major plumbing fixtures; and 10 days for other qualifying repairs.
Washington State law requires landlords to disclose their tenant screening criteria before obtaining information about a prospective tenant. The disclosure must identify the types of information that will be reviewed, the criteria that could result in denial, and whether the landlord accepts comprehensive reusable tenant screening reports. If a consumer report is used, landlords must also provide information about the reporting agency and the applicant’s rights if the application results in a denial or other adverse action.
Landlords must provide tenants with advance notice before entering an occupied rental property, except in emergencies, abandonment, or other circumstances allowed by law. For inspections, repairs, or services, landlords must generally provide at least two days’ written notice, according to Washington State’s right of entry law. When showing the property to prospective purchasers or tenants, landlords must provide at least one day’s notice. Entry must occur at reasonable times, and the notice must include the required information about when entry will occur.
Seattle rental property owners must comply with city-specific requirements in addition to Washington State landlord-tenant law. These Seattle rental laws affect how owners screen applicants, collect move-in funds, increase rent, maintain and inspect properties, and end tenancies.
Seattle’s Just Cause Eviction Ordinance limits the circumstances under which a landlord can end a tenancy. Property owners must have one of the legally recognized just causes and follow the notice and documentation requirements associated with that reason.
Qualifying reasons can include nonpayment of rent, an owner or qualifying family member moving into the property, or substantial property renovations that require the tenant to vacate. Requirements vary depending on the reason for ending the tenancy, so owners should verify the applicable rules before issuing a notice.
Seattle’s Rental Registration and Inspection Ordinance, commonly called RRIO, requires rental properties to be registered with the city and inspected for compliance with minimum housing and safety standards.
Property owners must keep their registration current, complete required inspections, and correct violations identified during inspections within applicable deadlines. Because RRIO requirements include specific registration, inspection, and documentation procedures, owners should carefully track their property’s compliance status and upcoming deadlines.
Seattle places additional restrictions on the deposits and move-in fees landlords can charge tenants. Currently, under Seattle’s regulations, “Security deposit and fees combined cannot exceed one month's rent.” These rules limit certain move-in costs and require landlords to offer installment payment options in qualifying situations. Property owners should confirm current limits before collecting move-in funds and clearly document deposits, nonrefundable fees, and applicable payment arrangements in the rental agreement.
Seattle’s Fair Chance Housing Ordinance limits how landlords can use an applicant’s criminal history when screening prospective tenants. This means Seattle property owners cannot use criminal history in the same way landlords may be permitted to elsewhere in Washington.
Screening criteria and application procedures must comply with Seattle’s Fair Chance Housing requirements while also meeting Washington State disclosure requirements. Owners should use consistent, clearly documented screening criteria and verify that their screening process reflects current city rules.
Seattle landlords must follow city-specific requirements before increasing rent or other housing costs. These requirements include providing tenants with at least 180 days’ written notice before an increase takes effect. Currently, according to Seattle law, “As of May 7, 2025, maximum rent increase of 7% plus the consumer price index (CPI) up to a maximum of 10% per year.” Additionally, the law requires owners, landlords, and property managers to provide at least 180 days' written notice of increases in housing costs.
Notices must also meet Seattle’s requirements for both content and delivery. Property owners should confirm the current rules before issuing an increase because an incorrectly prepared or delivered notice can affect when the increase can legally take effect.
Seattle has additional restrictions and defenses to evictions that can prevent certain evictions during the winter and during the school year for qualifying households with children. These protections can affect when an owner may pursue an eviction, even when other requirements have been met. Because eligibility and exceptions depend on the circumstances, property owners should verify the current Seattle requirements before beginning the eviction process.
Seattle property owners must comply with both Washington State landlord-tenant law and additional City of Seattle requirements. In areas where both jurisdictions regulate the same part of the rental process, owners must understand how the requirements work together and ensure their practices comply with all applicable rules.

Because Seattle rental laws add another layer of requirements to Washington State law, property owners need processes that account for both. Keeping leases, notices, screening criteria, property records, and other documentation current can help owners manage these overlapping requirements consistently.
Staying compliant with Seattle landlord-tenant laws requires property owners to keep up with both city and Washington State requirements throughout the rental lifecycle. Keeping documents current, tracking deadlines, following consistent screening and notice procedures, and meeting inspection and maintenance requirements can help reduce the risk of compliance issues.

Compliance is an ongoing part of owning a Seattle rental property. Consistent processes make it easier to keep up with changing requirements and manage the property responsibly over time.
Yes. Seattle landlords must comply with applicable Washington State landlord-tenant laws as well as City of Seattle rental housing requirements. Seattle ordinances add local requirements in areas such as tenant screening, rental property registration and inspections, rent increases, move-in costs, and ending a tenancy.
Most rental properties in Seattle must be registered through the Rental Registration and Inspection Ordinance (RRIO) program. Property owners must maintain their registration and complete required inspections according to the City of Seattle’s requirements, although certain properties may qualify for exemptions.
Seattle landlords must provide at least 180 days’ written notice before increasing rent or other housing costs. Housing costs can increase only when a term lease is up for renewal or when the rental agreement is month-to-month, and the notice must meet Seattle’s requirements for content and delivery.
Seattle’s Fair Chance Housing Ordinance restricts how landlords can use criminal history when screening rental applicants. Property owners should ensure their screening criteria and application processes comply with Seattle’s Fair Chance Housing requirements as well as applicable Washington State screening laws.
Seattle’s Just Cause Eviction Ordinance requires landlords to have a legally recognized reason for ending certain tenancies. The city identifies qualifying reasons and establishes requirements that landlords must follow based on the specific cause for terminating the tenancy.
The consequences depend on the requirement and circumstances involved. Noncompliance can result in financial penalties, enforcement actions, legal disputes, invalid notices, delays or restrictions in recovering possession of a property, or other consequences under applicable city and state laws.
Seattle property owners must navigate both city and Washington State rental laws, making compliance an ongoing part of managing a rental property. Staying current with changing requirements, deadlines, and documentation can help protect your investment and avoid preventable compliance issues.
