Washington Landlord-Tenant Laws: The Complete 2026 Overview

Washington sets no cap on the deposit amount, but it conditions the deposit on paperwork and locks down the return. Under RCW 59.18.260 a landlord may not collect a deposit at all unless the rental agreement is in writing, states the terms on which the deposit may be withheld, and a written checklist describing the condition and cleanliness of the premises, fixtures, equipment, appliances and furnishings is signed and dated by both parties with a copy to the tenant. RCW 59.18.280(1)(c)(iii) then bars withholding anything for an item whose condition was not documented in that checklist. After the tenancy ends and the tenant surrenders the unit, the landlord must return the deposit, or a full and specific written statement of deductions with the estimates or invoices substantiating each damage charge, within thirty days — a deadline raised from twenty-one days by 2023 c 331 and still printed as twenty-one on a great many Washington pages. Failing to deliver that statement on time forfeits the right to withhold any portion and bars the landlord from asserting any claim or defence for retaining it. A landlord who wrongfully withholds is liable for the full deposit, and a court may award up to twice the deposit for an intentional refusal, plus attorney fees. Deposit disputes are handled in Small Claims Court, which hears claims up to ten thousand dollars without an attorney.

Washington is a just-cause state: under RCW 59.18.650 a landlord must have a statutory ground to end a tenancy or decline to renew, and cannot simply tell a tenant to leave. To evict for nonpayment, the landlord must first serve a written fourteen-day notice to pay or vacate, a period lengthened by the 2019 law from the old three days. If the tenant does not pay or leave, the landlord files an unlawful detainer action in Superior Court, and the tenant has a short window to respond before a hearing. Self-help evictions – changing locks, removing belongings, or shutting off utilities – are illegal and expose the landlord to damages, statutory penalties, and attorney fees. Only a sheriff acting on a writ of possession may physically remove a tenant.

Washington puts landlord entry directly in statute. Under RCW 59.18.150 a landlord must give at least two days’ written notice to enter for inspection, repairs, maintenance, or agreed services, and at least one day’s notice to show the unit to prospective or actual purchasers or tenants, entering only at reasonable times. The notice period is set by the purpose of the entry, which is the detail many landlords get wrong. Entry without notice is limited to a genuine emergency such as a fire, flood, or gas leak. The tenant may not unreasonably refuse a properly noticed entry, but the landlord may not abuse the right of access or use it to harass the tenant. The lease may add detail about hours or delivery, but it cannot authorize entry on less than the statutory two-day or one-day notice.

Washington now has rent control. House Bill 1217, enacted in 2025, created a statewide cap on annual rent increases: the increase may not exceed seven per cent plus the consumer price index or ten per cent, whichever is less. The percentage is not a number to memorise. RCW 59.18.700(1)(c) directs the Department of Commerce to calculate the following calendar year’s maximum from the June twelve-month percent change in the consumer price index for all urban consumers, all items, for the Seattle area as published by the federal Bureau of Labor Statistics, and to publish it on its website and in a press release; in practice that lands shortly after the mid-July release of the June data. The published maximums are 9.683 per cent for 1 January to 31 December 2026 and 10 per cent for 1 January to 31 December 2027, so read the figure for the year in which the increase takes effect rather than the one in front of you. A landlord must give at least ninety days’ prior written notice of an increase under RCW 59.18.140(3)(a) — up from sixty days before the 2025 act — on a form substantially the same as the one set out in RCW 59.18.720(3), served in the manner required by RCW 59.12.040. There is no add-days-for-mail extension of the ninety days; the five extra days in RCW 59.12.040 govern when an unlawful detainer action may be commenced, not the length of a rent-increase notice. Thirty days applies instead where the tenancy is subsidized and the rent is based on the tenant’s income, which RCW 59.18.720(2) makes clear does not include a portable tenant-based voucher. No increase is allowed during the first twelve months of a tenancy, and newly built housing is exempt from the cap for twelve years. During a fixed-term lease the rent is locked for the term unless the lease itself contains an escalation clause. An increase above the cap, or one imposed in the first year, is unlawful and gives the tenant remedies, and retaliatory or discriminatory increases remain barred regardless of amount.

RCW 59.18.170 governs residential late fees in Washington. There is no fixed statutory dollar cap, but a late fee must be stated in a written lease, be a reasonable estimate of the uncertain damages a late payment causes rather than a penalty, and be charged only after rent is actually past due. Washington fixes no maximum amount, and no reported Washington authority sets a safe-harbour percentage, so treat any figure you see quoted as a lease-drafting convention rather than a legal ceiling — the twenty-dollars-or-twenty-per-cent limit widely attributed to Washington actually comes from RCW 19.150.150, the Self-Service Storage Facilities act, which speaks of an owner and the occupant of a storage space and has nothing to do with a dwelling unit. What Washington does fix is the timing. RCW 59.18.170(2) forbids any late fee for rent that is paid within five days following its due date, and this is not a customary grace period but a statutory bar: RCW 59.18.230(2)(i) makes a lease term charging a late fee inside that window a prohibited provision, unenforceable however it is worded. Once rent is more than five days past due, the fee may be charged from the first day after the due date. RCW 59.18.170(3) adds a further right no template carries: a tenant whose primary source of income is a regular monthly source of governmental assistance received after the rent due date may require the due date to be moved, in writing, by up to five days. Several cities cap the amount even though the state does not — Seattle, Tacoma and Burien at ten dollars a month among them. A returned-check or non-sufficient-funds fee is enforceable when the lease provides for it and reflects the landlord’s real cost, typically around forty dollars. A purely punitive fee, or one charged during a grace period, is unenforceable.

Every Washington tenancy carries an implied warranty of habitability under RCW 59.18.060, and the state sets the strictest repair clock in the country. Once the tenant gives written notice of a covered defect, RCW 59.18.070 requires the landlord to act within twenty-four hours to restore lost heat, water, or electricity or fix an imminently hazardous condition; within seventy-two hours for a supplied refrigerator, range, or major plumbing fixture; and within ten days for all other repairs. The heating system must be able to maintain a room temperature of at least fifty-eight degrees. If the landlord misses a deadline, the tenant’s statutory remedies open at once: repair-and-deduct up to two months’ rent in a twelve-month period for licensed-contractor work under RCW 59.18.100, rent escrow, damages, or termination for a serious unremedied defect. Retaliation against a tenant who asserts a habitability right is barred, and a retaliatory action soon after a complaint is presumed retaliatory.

Washington codifies several protected reasons a tenant may end a fixed-term lease early without owing the balance. A victim of domestic violence, sexual assault, unlawful harassment, or stalking may terminate under RCW 59.18.575 with written notice plus a protection order or a qualified third party’s report, requested within ninety days of the qualifying act, and stays liable only for the month of quitting. Military servicemembers may terminate under the federal Servicemembers Civil Relief Act and Washington’s armed-forces exception, RCW 59.18.220. A tenant in an uninhabitable unit may terminate under RCW 59.18.060, 59.18.070, and 59.18.090 after written notice and a failed cure. For a tenant who simply leaves without a statutory ground, RCW 59.18.310 imposes a duty on the landlord to mitigate by making a reasonable effort to re-rent, so the departing tenant owes only the vacancy gap, not the entire remaining term, and any clause waiving that duty is void under RCW 59.18.230.

Ending a Washington tenancy depends on its type and on the just-cause rule. A tenant may end a month-to-month tenancy with at least twenty days’ written notice under RCW 59.18.200, but a landlord may end or decline to renew a tenancy only for a statutory just-cause ground under RCW 59.18.650 – substantial lease violations, owner move-in, removal of the unit from the market, or another enumerated reason – with supporting documentation. A fixed-term lease generally runs to its end date, and the lease often requires thirty to sixty days’ notice of non-renewal. A tenant who stays past the end date becomes a holdover; the landlord must file an unlawful detainer action in District or Superior Court rather than use self-help, and must still establish just cause. Oral notice is never sufficient, and accepting rent after serving notice can waive the termination.

For an actual pet, Washington lets a landlord charge a pet deposit or pet rent, with no separate cap, as long as the terms are in the written rental agreement and any nonrefundable fee is labeled as such. Assistance animals are treated completely differently. Under the federal Fair Housing Act and the Washington Law Against Discrimination in RCW Chapter 49.60, a service animal or emotional support animal is not a pet – a landlord may not charge any pet deposit, fee, or rent, and may not apply a breed or weight restriction or a no-pet policy to it. When the disability or the animal’s role is not obvious, the landlord may request reliable documentation from a legitimate provider, but may not demand certification, registration, or a specific certificate. The tenant remains liable for any actual damage the animal causes. Knowingly misrepresenting an animal as a service animal is a civil infraction under RCW 49.60.214, punishable by a fine of up to five hundred dollars.

Washington regulates tenant screening closely, so the binding rules are both state and federal. Under RCW 59.18.257 a screening fee may not exceed the actual cost of obtaining the report, and the landlord must give the applicant written notice of the screening criteria and the fact that a report is being run before collecting the fee. With written authorization a landlord may pull a consumer report covering credit, rental and eviction history, income, and criminal background, but the Fair Credit Reporting Act requires a permissible purpose and consent first. Source of income is a protected class in Washington, so a landlord may not reject a Housing Choice Voucher outright. If a denial, a higher deposit, or a co-signer requirement rests on a consumer report, both the FCRA and Washington law require an adverse action notice naming the reporting agency. Blanket criminal-record bans are disfavored under the Fair Housing Act’s discriminatory-effects rule at 24 CFR section 100.500, reinstated effective May 1, 2023 and in force today, though HUD has proposed to remove it and reopened the comment period until October 9, 2026 (Docket No. FR-6540-P-01, 91 FR 1475, as supplemented by Docket No. FR-6540-P-02, 91 FR 51416) – a proposal is not a rule, so nothing has changed yet. HUD’s 2016 criminal-records guidance was withdrawn effective September 25, 2025 (Docket No. FR-6617-N-01, 91 FR 44867) and HUD has issued nothing to replace it, and section 100.500 imposes no individualized-assessment step of its own, so an individualized assessment is prudent risk management and the evidence that defends the decision rather than a federal requirement. The Supreme Court’s recognition of disparate-impact liability under the Fair Housing Act in Texas Department of Housing and Community Affairs v. Inclusive Communities Project (2015) is unaffected by either the withdrawal or the pending proposal.
