Landlord Responsibilities in Washington State: Repairs, Deposits, and Entry

Landlord responsibilities in Washington State are set by the Residential Landlord-Tenant Act (RLTA) and cover habitability, repairs, safety disclosures, rent increases, evictions, security deposits, entry into the unit, fair housing, and protection from retaliation. These duties run for the entire tenancy and cannot be waived by anything written into a lease.¹ Several of the most important rules, especially around rent increases and the grounds for ending a tenancy, expanded significantly in 2025.

Keeping the Unit Habitable

Every rental unit in Washington must be fit for human habitation throughout the tenancy, which means it has to substantially comply with state and local building and health codes.² In concrete terms, the landlord is responsible for:

Roofs, walls, floors, foundations, chimneys, and fireplaces that are weather-tight and in good repair.
Electrical, plumbing, and heating systems the landlord provided, with heat adequate to protect health in cold months.
A pest-control program in place at the start of the tenancy, with ongoing control in multi-unit buildings unless the tenant caused the infestation.
Common areas kept clean, sanitary, and free of fire or accident hazards.
Trash receptacles and regular removal in multi-unit buildings.

Single-family rentals shift trash removal and ongoing pest control to the tenant, though the landlord must still address infestations that exist when the lease begins.²

Making Repairs on Time

Once a tenant delivers written notice of a problem, Washington gives the landlord specific deadlines to begin repairs:³

24 hours for loss of hot or cold water, heat, or electricity, or any condition that is imminently hazardous to life.
72 hours for loss of a refrigerator, stove and oven, or a major plumbing fixture the landlord supplied.
10 days for all other repair issues.

These deadlines are when work must start, not finish, but the statute requires it to proceed with diligence. Verbal complaints and text messages don’t trigger the clock. Only notice delivered in writing or by regular mail starts the statutory timeline.

If a landlord blows past the deadline and still doesn’t fix the problem within a reasonable time, the tenant can terminate the lease in writing, leave without further rent obligations, and recover a pro-rata refund of prepaid rent, along with the right to bring a court action for damages or pursue other RLTA remedies.⁴

Safety Devices and Required Disclosures

Every unit needs adequate locks on doors and windows, and the landlord has to furnish the keys. Working smoke detectors are required, and the landlord must confirm in writing before the tenancy begins that the unit is equipped with them. That written notice also has to explain that maintenance, including battery replacement, becomes the tenant’s responsibility at move-in.² Carbon monoxide alarms are required in all residential rental buildings under the state building code, with the same tenant-maintenance arrangement once installed.⁵

A signed written fire safety notice is required at the start of every tenancy. In multi-unit buildings, the notice has to disclose whether the building has a sprinkler system, a fire alarm, a smoking policy, and whether emergency notification, relocation, or evacuation plans exist, with copies of any plans and a diagram of evacuation routes.²

If the property was built before 1978, federal law adds a layer. The landlord must give the tenant the EPA pamphlet “Protect Your Family From Lead in Your Home,” disclose any known lead paint hazards, and provide available inspection reports. A signed lead warning statement has to be kept on file for at least three years after the lease begins.⁶ Housing built after 1977 is exempt, as are certain short-term vacation rentals and some senior housing.

Limits on Rent Increases

Washington’s 2025 rent stabilization law (HB 1217) caps how much a landlord can raise rent in any 12-month period: 10 percent, or 7 percent plus the consumer price index, whichever is lower. The cap for 2026 works out to a maximum of 9.683 percent.⁷ Manufactured and mobile home park lot rents are capped at 5 percent annually.

Two more rules sit on top of the cap. A landlord cannot raise rent at all during the first 12 months of a tenancy, whether the lease is fixed-term or month-to-month. And any increase requires at least 90 days’ advance written notice.⁷ Some cities add longer notice periods, so the 90-day rule is a floor.

Just Cause to End a Tenancy

Washington landlords cannot end a tenancy or decline to renew a lease without a specific qualifying reason listed in the RLTA.⁸ The common grounds include:

Nonpayment of rent, after a written pay-or-vacate notice giving the tenant the statutory period to catch up.
Material lease violations, with written notice identifying the violation and at least 10 days to cure.
Waste, nuisance, or unlawful activity, with at least three days’ written notice to quit.
Owner or immediate family moving in as a primary residence, but only if no equivalent unit is available in the same building, with at least 90 days’ notice.
Sale of a single-family residence, with at least 90 days’ notice.
Condemnation or certification that the unit is uninhabitable, with at least 30 days’ notice.

Vague dissatisfaction, or wanting to replace a tenant who complained to a code inspector, is not a valid ground. A landlord who tries to end a tenancy outside the statutory list risks having the eviction thrown out.

Handling the Security Deposit

A landlord cannot collect a security deposit in Washington without first providing a written rental agreement and a written move-in checklist describing the condition of walls, floors, fixtures, appliances, and furnishings. Both parties sign and date the checklist, and the tenant gets a copy.⁹ A landlord who skips the written checklist can be held liable to the tenant for the full deposit amount, and no deposit can be withheld for normal wear and tear.

After the tenancy ends and the tenant vacates, the landlord has 30 days to either return the full deposit or send a written statement explaining every deduction, with supporting documentation. Missing that window is costly: the landlord forfeits any right to keep the deposit and cannot raise a defense for doing so. If a court finds the refusal was intentional, the penalty can reach twice the deposit, plus the tenant’s attorney’s fees.¹⁰ This 30-day rule is one of the most commonly violated provisions in the RLTA and one of the easiest for a tenant to enforce.

Entering an Occupied Unit

Washington law puts strict limits on when a landlord can enter.¹¹

Inspections, repairs, and maintenance require at least two days’ written notice, stating the exact date and time or a specific time window.
Showing the unit to prospective buyers or tenants requires at least one day’s written notice.
Emergencies and abandonment require no notice.

Every entry notice must include a telephone number the tenant can call to object or reschedule. A landlord cannot abuse the right of access or use it to harass. A tenant can recover up to $100 for each violation, along with actual damages and reasonable attorney’s fees for a willful invasion of privacy.¹¹

Fair Housing and Assistance Animals

The federal Fair Housing Act prohibits discrimination in renting based on race, color, national origin, religion, sex, familial status, and disability.¹² Washington State adds sexual orientation, gender identity, veteran or military status, and immigration status. A landlord cannot reject applicants, set different lease terms, or treat tenants differently based on any protected characteristic.

Assistance animals are a frequent trip point. A service animal or emotional support animal is not a pet. A landlord must grant a reasonable accommodation to a no-pets policy for a tenant with a disability-related need for an assistance animal, cannot charge pet fees or pet deposits for the animal, and cannot impose breed, size, or weight restrictions. The tenant is still responsible for any damage the animal causes. A landlord can request written verification of the need from a medical or mental health provider. Denial is only allowed for a direct, documented threat to health or safety, substantial property damage that can’t be reduced, or an undue burden on operations.

No Retaliation for Exercising Tenant Rights

A landlord cannot retaliate against a tenant for reporting a code violation, requesting a repair, joining a tenants’ organization, or filing a complaint with a government agency. Retaliation includes raising rent, cutting services, adding obligations, or trying to evict.¹³ A landlord who retaliates is liable for damages, and a retaliatory eviction can be raised as a defense in court. The protection is what allows every other duty in this article to actually be enforced.
