Can I Sue My Landlord in Washington?

Yes — in many situations. These are the main claims Washington tenants bring, what the law lets you recover, and where to file. Each rule links to the statute or official source. Most claims under the small claims limit can be filed without a lawyer.

Before you sue

Write down what happened, with dates, and keep photos, texts, emails and receipts.
Send your landlord a written demand (templates below) and give a reasonable deadline.
Check the deadline to sue and the court's dollar limit (below).
If the amount is over the small claims limit, or you are facing eviction, talk to a lawyer or legal aid first.

Your security deposit wasn't returned

Penalty for withholding	Landlord who fails to provide the statement/documentation within 30 days owes the full deposit and loses the right to assert claims against it; court may award up to two times the deposit for intentional refusal; prevailing party gets costs and reasonable attorneys' fees. Collecting a deposit without a move-in checklist makes the landlord liable for the deposit amount (RCW 59.18.260). For tenancies starting on or after July 23, 2023, landlord suits for damages above the deposit must be filed within three years. Source: RCW 59.18.280(2)-(3); RCW 59.18.260
Deposit return deadline	30 days after the rental agreement terminates and the tenant vacates (or 30 days after the landlord learns of abandonment). Most recently amended by 2023 c 331 s 4 (the deadline is 30 days under current text). Delivery may be personal or first-class mail to the tenant's last known address. Source: RCW 59.18.280(1)

Your landlord retaliated after you complained

Landlord retaliation	Landlord may not evict, raise rent, reduce services or increase obligations (or threaten to) in retaliation for good-faith complaints to a government authority about code violations or for asserting rights under RCW 59.18. Action within 90 days after the protected act (or a resulting inspection/proceeding) is presumed retaliatory. Presumption is rebuttable and does not arise if tenant is in rent arrears when a termination notice is given. Prevailing party recovers costs and reasonable attorney's fees.

Your landlord won't make repairs

Repair and deduct	Yes. After written notice and the landlord's failure to start repairs within the statutory period, tenant may (a) hire a licensed/qualified contractor and deduct up to two months' rent per repair (max two months' rent in any 12 months), or (b) make the repair personally and deduct up to one month's rent per repair (max one month's rent in any 12 months). Tenant must be current on rent and utilities before using any RLTA remedy (RCW 59.18.080) and must give notice under RCW 59.18.070; landlord must begin remedial action within 24 hours (no hot/cold water, heat or electricity, or imminently hazardous), 72 hours (landlord-supplied refrigerator, range/oven, or major plumbing fixture), or 10 days (all other cases).

Withholding rent	No general right to withhold rent. Tenant may deposit rent into an escrow account only after a local government official certifies a condition that substantially endangers health or safety and the landlord fails to repair; tenant must notify the landlord within 24 hours of the deposit using the sworn form. Local government must inspect within five days of request. Tenant must first determine in good faith that repair-and-deduct is not feasible. Source: RCW 59.18.115
Mold	Disclosure required: the landlord must give tenants information provided or approved by the Department of Health about the health hazards of indoor mold and how tenants can control mold growth, either in writing to each tenant or posted in a visible public location on the property. The landlord is immune from civil liability for failing to do so unless the failure is knowing and intentional. There is no mold-specific remediation standard; mold is handled under the landlord's general duty to keep the premises fit for habitation, comply with health and safety codes and make repairs. Mold disclosure was added in 2005 (2005 c 465). Local housing codes may contain additional standards. Source: RCW 59.18.060(1), (5), (14), (15)
Pests & bed bugs	The landlord must provide a reasonable program for the control of insects, rodents and other pests at the start of the tenancy and, except in a single-family residence, must control infestation during the tenancy unless the tenant caused it. No bed-bug-specific statute (no disclosure or inspection rule). The tenant must pay all extermination and fumigation costs for an infestation the tenant caused. In a single-family residence, pest control during the tenancy is not a statutory landlord duty (the lease may assign it). Source: RCW 59.18.060(4); 59.18.130(2)
Heat	Yes. The landlord must provide facilities adequate to supply heat (and water and hot water) as reasonably required by the tenant, and keep heating facilities it supplies in reasonably good working order. After notice, a defect depriving the tenant of heat must be remedied within 24 hours (where possible). State law sets no minimum indoor temperature or heating season. Some cities (for example, Seattle) set minimum temperatures by ordinance. It is unlawful for a landlord to intentionally cause termination of a tenant's heat or other utilities except for repairs (RCW 59.18.300). Source: RCW 59.18.060(8), (11); 59.18.070(1)

Your landlord entered without notice or invaded your privacy

Landlord entry notice	At least two days' written notice stating the exact date(s) and time or a time window, with a phone number for objections; one day's notice to show the unit. No notice required in an emergency or abandonment. Entry only at reasonable times; landlord may not abuse access to harass the tenant. Source: RCW 59.18.150(6)
Cameras & privacy	No landlord camera statute. Washington is an all-party consent state: recording a private conversation or private communication without the consent of all participants is unlawful. Voyeurism laws make it a crime to knowingly view, photograph or film a person without knowledge and consent in a place where the person would reasonably expect privacy. New smart-access-system rules (effective Jan. 1, 2027) limit the data a landlord's electronic/biometric entry system may collect, require a written privacy policy (including what data on guests is collected), and require a non-biometric, non-phone alternative key on request. Voyeurism text: https://app.leg.wa.gov/RCW/default.aspx?cite=9A.44.115. Smart access provisions: Laws of 2026, ch. 55. Landlord entry generally requires 2 days' notice (RCW 59.18.150).

You were refused or treated differently because of Section 8 or other income

Statewide ban on refusing Section 8 / source of income	Yes, statewide. Landlords may not refuse to rent, evict, set different terms or fees, discourage, misrepresent availability, or advertise preferences based on a tenant's source of income, which includes housing assistance (e.g., vouchers), public assistance, emergency rental assistance, veterans benefits, Social Security/SSI and other federal, state, local or nonprofit programs. If an income threshold is used, the voucher/subsidy must be subtracted from the rent before applying it. Narrow exception where the subsidy requires an inspection and repairs would cost more than $1,500 and mitigation funds were not received. Liability up to 4.5 times monthly rent plus costs and attorney's fees. Source: RCW 59.18.255

Other claims tenants bring in Washington

Constructive eviction (conditions forced you out)	No Washington statute uses the term "constructive eviction," but the Residential Landlord-Tenant Act lets a tenant move out and stop paying rent over unrepaired defects. After the tenant gives written notice of a defect and the statutory repair period passes, if the landlord still fails to fix the condition within a reasonable time, the tenant may end the rental agreement and move out on written notice, owing no rent after the move-out date, and is entitled to a pro rata refund of prepaid rent and a full statement on the deposit. Other options include suing or pursuing other remedies in the chapter, repair-and-deduct (RCW 59.18.100), and paying rent into escrow for substandard conditions certified by a government inspector (RCW 59.18.115). Whether Washington courts also apply a common-law constructive-eviction doctrine is not addressed in the statute. Source: RCW 59.18.090(1); 59.18.070
Injuries on the property	The landlord must keep the premises fit for human habitation at all times, including substantially complying with codes when a violation endangers health or safety, keeping structural parts in reasonably good repair, keeping shared areas reasonably clean, sanitary and safe from defects increasing the hazards of fire or accident, and providing reasonably adequate locks. A lease cannot excuse or limit the landlord's liability arising under law or make the tenant indemnify the landlord for it, and any lease clause waiving the Act is unenforceable. The Act does not itself set a rule for personal-injury lawsuits; whether a landlord is liable for a particular injury is decided by the courts under negligence law.
