Washington Landlord Tenant Laws: What Property Owners Need to Know

Jun 19, 2026

Spring is a busy season in residential real estate. Leases turn over, new tenants sign, and landlords who haven’t reviewed their policies in a while might find themselves navigating tough questions.

Whether you own a single rental property or manage a portfolio across Washington state, staying current on tenant rights law is how you protect your investment. Washington state has a myriad of laws landlords need to know and is considered a renter-friendly state. Here’s a brief overview of some of the discrepancies we see most often.

Washington State Security Deposit Rules

In Washington, landlords must honor a written request from a tenant to pay deposits and nonrefundable fees in installments under RCW 59.18.610, unless the total is less than 25% of the first full month’s rent and last month’s rent is not required upfront.

We recommend that landlords and property managers review deposit agreements annually to confirm they are specific, state-compliant, and clearly outline permissible deductions.

Landlord Habitability Requirements in Washington

Washington requires landlords to maintain rental properties in a habitable condition. RCW 59.18.060 sets specific repair timelines after written tenant notice: 24 hours for loss of heat, water, or electricity; 72 hours for major appliances; and 10 days for all other defects, including pest issues. RCW 59.18.060 requires landlords to provide a reasonable pest control program at the start of tenancy, and except for single-family residences, to control infestation during tenancy unless it is caused by the tenant.

Failure to respond within these windows gives tenants the right to terminate the lease, pursue arbitration, or seek legal relief. A documented process for receiving and responding to maintenance requests is one of the simplest ways to limit your exposure.

Landlord Entry Notice Requirements

Washington’s requirements under RCW 59.18.150 state at least two days’ written notice, stating the exact date and time window of entry and a phone number for the tenant to object or reschedule. Emergencies and abandonment are the only situations that excuse notice entirely. Showings to prospective buyers or tenants require a one day notice.

Rent Increases and Fees

Washington’s rent stabilization law prohibits increases during the first year of tenancy. After that, the cumulative increases in rent over any 12 month period is capped at the lesser of 7% plus the Seattle-area CPI or 10%. Violations can result in refunds, up to three months of damages, and civil penalties up to $7,500 per violation. Landlords must give at least 90 days written notice of any rent increase.

Eviction Notice Requirements: Washington

In Washington, nonpayment of rent requires a 14-day pay or vacate notice, the notice form is governed by RCW 59.18.057, the unlawful-detainer trigger is RCW 59.12.030(3). Note that notice requirements often differ between states, so it’s important not to rely on the same template if you have properties across state lines.

Outdated lease templates, inconsistent notice practices, and deposit policies that don’t reflect current law create real exposure for landlords. Landlords dealing with unauthorized occupants should also understand how squatter removal works in their state.

Work With a Landlord-Tenant Attorney in Washington

Landlord-tenant law in Washington changes more often than most property owners realize. Washington’s rent stabilization rules, updated eviction notice requirements, and habitability timelines have all shifted in recent years, and we anticipate more changes to come. A lease template or deposit policy that was compliant two years ago may not be today.

The cost of a landlord-tenant dispute, whether that’s a wrongful withholding claim, an improper eviction, or a rent increase violation, almost always exceeds the cost of a quick legal review. Malek + Malek’s real estate attorneys are licensed in Washington state, and several other Western states, and work regularly with landlords and property managers across the Inland Northwest.

Frequently Asked Questions (FAQs)

What are the main differences between Idaho and Washington landlord-tenant laws?

The two states differ significantly on security deposit timelines, rent increase caps, eviction notice periods, and entry notice requirements. Washington has more tenant-protective regulations overall, including rent stabilization limits and specific repair timelines, while Idaho’s rules give landlords somewhat more flexibility. 

How much notice does a landlord need to give before entering a rental property in Washington?

Washington requires a minimum of two days’ written notice that includes the specific date, time window, and a phone number for the tenant to reschedule. Emergencies and abandonment are the only situations that excuse notice entirely. Showings to prospective buyers or tenants require a one day notice.

Can a landlord raise rent at any time in Washington?

No. Under Washington’s rent stabilization law, landlords cannot raise rent during the first year of tenancy. After that, the cumulative amount of an increase in rent over any 12 month period is capped at the lesser of 7% plus the Seattle-area CPI or 10%. Violations can result in significant financial penalties. Landlords must give at least 90 days of written notice of any rent increase.

What is the eviction notice period for nonpayment of rent in Washington?

In Washington, landlords must issue a 14-day pay or vacate notice for nonpayment of rent.
