Washington Residential Lease Agreement Laws and Disclosures

Washington residential lease agreement laws are set out in the Residential Landlord-Tenant Act at Chapter 59.18 RCW, which dictates what a lease must contain, what disclosures the landlord must hand over, how much can be collected upfront, which clauses courts will refuse to enforce, and the limited grounds on which a tenancy can end. Whether you are reviewing a lease before signing or drafting one to offer, the same statute governs both sides of the page.

What the Lease Itself Must Contain

Start with the basics: the full legal names of all adult occupants, the complete address of the unit including any apartment number, the start and end dates of the tenancy, the monthly rent, and the day it is due. The lease should specify acceptable payment methods and identify which party pays for water, gas, electric, and trash.

Two points that generic templates often miss. The agreement should include the name and address of the person authorized to manage the property and receive legal notices for the landlord, because proper service matters if a dispute reaches court. If any deposit or nonrefundable fee is being collected, the lease must state the conditions under which the deposit is refundable and identify the financial institution where the money is held.1Washington State Legislature. RCW 59.18.270 – Moneys Paid as Deposit or Security for Performance by Tenant

A verbal agreement is legally sufficient for a tenancy of one year or less. Enforcing one when memories diverge is another matter.

Disclosures a Landlord Must Give at Signing

Several documents have to change hands at the start of a new tenancy. Skipping any of them can weaken the landlord’s position later.

  • A copy of the Department of Health’s pamphlet on the health risks of indoor mold and how to control it, provided again at each renewal.2Washington State Legislature. RCW 59.18.060 – Landlord Duties
  • The fire safety information pamphlet developed by the state fire marshal, which covers smoke detection requirements.2Washington State Legislature. RCW 59.18.060 – Landlord Duties
  • Written notice that the full Residential Landlord-Tenant Act is available on the Washington State Legislature’s website, along with the web address. At each renewal, the landlord must also provide a summary of the act or a link to the Department of Commerce page hosting it.3Washington State Legislature. Washington Code 59.18 – Residential Landlord-Tenant Act
  • For any building constructed before 1978, federal law requires a lead-based paint disclosure form, a copy of the EPA pamphlet “Protect Your Family From Lead in Your Home,” and a lead warning statement inside the lease itself.4US EPA. Lead-Based Paint Disclosure Rule Section 1018 of Title X

Some cities add their own. Seattle requires voter registration information at move-in, with damages up to $1,000 and grounds for the tenant to terminate the lease if the landlord fails to provide it. Check local ordinances before finalizing.

Security Deposit Rules

Washington’s deposit rules are detailed, and small procedural mistakes can cost the landlord the entire deposit.

The 25 Percent Cap

Total deposits and nonrefundable fees combined cannot exceed 25 percent of the first full month’s rent.5Washington State Legislature. RCW 59.18.610 On a $2,000 unit, that is a $500 maximum upfront. Landlords still working from older forms often collect illegal amounts without realizing it.

Move-In Checklist

No deposit may be collected unless the landlord provides a written checklist describing the condition and cleanliness of the unit at move-in. The checklist has to cover walls, paint, carpets, flooring, furniture, appliances, and fixtures. Both parties sign and date it, and the tenant keeps a copy.6Washington State Legislature. RCW 59.18.260 – Moneys Paid as Deposit or Security for Performance by Tenant – Written Checklist Required Skip the checklist and the landlord becomes liable for the full deposit, plus the tenant’s attorney’s fees.1Washington State Legislature. RCW 59.18.270 – Moneys Paid as Deposit or Security for Performance by Tenant

Trust Account

The deposit must sit in a trust account at a financial institution, and the tenant must be told the name and address of that institution.1Washington State Legislature. RCW 59.18.270 – Moneys Paid as Deposit or Security for Performance by Tenant The tenant’s money stays separate from the landlord’s operating funds.

Returning It

After move-out, the landlord has 30 days to return the deposit in full or send a written statement explaining every withholding. That statement must include copies of invoices, estimates, or receipts. If the landlord or an employee did the repair work, the statement has to show the hours and hourly rate.7Washington State Legislature. RCW 59.18.280 A line item that says “cleaning — $300” with nothing behind it will not survive a challenge.

Wear Versus Damage

A landlord cannot withhold any portion of the deposit for wear resulting from ordinary use.1Washington State Legislature. RCW 59.18.270 – Moneys Paid as Deposit or Security for Performance by Tenant Faded paint, minor scuffs on hardwood, and small nail holes are wear. Stains and burns on carpet, large holes in walls, and pet damage are deductible. The move-in checklist is what makes the distinction provable.

Clauses That Won’t Hold Up in Court

Any provision that waives a tenant’s rights under the Residential Landlord-Tenant Act is void as a matter of public policy.8Washington State Legislature. RCW 59.18.230 The statute also specifically prohibits terms that require a tenant to:

  • Give up the right to sue, including joining a class action against the landlord.
  • Sign a nondisclosure agreement about rent, deposits, fees, or concessions.
  • Pay the landlord’s attorney’s fees outside what a court might award under a specific statutory provision.
  • Release the landlord from legal liability.
  • Submit to binding arbitration, unless the landlord pays the full cost and the agreement is notarized.
  • Accept a late fee for rent that arrives within five days of the due date.
  • Pay rent only by electronic means; a non-electronic option must be available.

Any clause that creates a lien on the tenant’s personal property or lets the landlord seize belongings for unpaid rent is also void.8Washington State Legislature. RCW 59.18.230 If any of these appear in a lease you are being asked to sign, they carry no legal force, but their presence tells you something about how the landlord approaches the relationship.

Late Fees and Rent Increases

Rent has a statutory five-day grace period. No late fee is chargeable for rent paid within five days of the due date. A tenant whose primary income is a regular monthly government benefit that arrives after rent is due can request in writing that the due date shift by up to five days, and the landlord has to agree.9Washington State Legislature. RCW 59.18.170

Rent increases require at least 90 days’ written notice statewide, and 180 days in Seattle. An increase imposed on shorter notice is unenforceable, and raising rent in retaliation for a tenant exercising legal rights is independently illegal.10Washington State Legislature. RCW 59.18.240

Landlord Entry

A landlord does not have open access. Outside of emergencies or abandonment, the landlord must give at least two days’ notice and enter only at reasonable times. For showings to prospective buyers or tenants, one day’s notice is enough.11Justia Law. Washington Revised Code RCW 59.18.150 – Landlords Right of Access Repeated entry used to harass a tenant is prohibited, and a lease clause purporting to grant broader entry rights would be an unenforceable waiver.

Ending the Tenancy

A tenant on a month-to-month tenancy has to give at least 20 days’ written notice before the end of a rental period. Military service members with permanent change-of-station or deployment orders that do not allow that much lead time can terminate on shorter notice.12Washington State Legislature. RCW 59.18.200

Washington is a just cause eviction state. A landlord cannot evict, refuse to renew, or terminate a periodic tenancy except for a reason listed in the statute.13Washington State Legislature. RCW 59.18.650 – Eviction of Tenant, Refusal to Continue Tenancy The most common lawful grounds:

  • Unpaid rent after a written pay-or-vacate notice.
  • A substantial breach of a material lease term that the tenant does not fix within at least 10 days after written notice.
  • Nuisance or illegal activity that substantially interferes with neighbors, on three days’ notice.
  • Owner or immediate family move-in as a primary residence, with at least 90 days’ advance written notice.
  • Sale of a single-family home, with at least 90 days’ notice.
  • Demolition or substantial rehabilitation, with at least 120 days’ notice.

Trying to end a tenancy for a reason outside this list, or retaliating against a tenant who reported code violations or asserted legal rights, exposes the landlord to damages.10Washington State Legislature. RCW 59.18.240 Many landlords assume that when a fixed-term lease expires they can simply decline to renew. In Washington, that assumption is wrong.

Fair Housing and Assistance Animals

Every Washington lease is subject to the federal Fair Housing Act, which prohibits discrimination based on race, color, religion, sex (including sexual orientation and gender identity), familial status, national origin, and disability. A lease term that singles out a protected group, such as restricting families with children to certain floors or charging higher deposits, is illegal.

Disability protections drive several common lease issues. Landlords must permit reasonable modifications to the physical unit and reasonable accommodations to rules or policies when a person with a disability needs them for equal use of the property. Pet policies are the frequent flashpoint. As of 2026, HUD has rescinded its earlier guidance treating emotional support animals as presumptively reasonable, and now only animals individually trained to perform disability-related tasks receive that federal presumption. State and local law can still provide broader protection, and a blanket denial of every animal accommodation request without evaluating training and disability-related need remains a fair housing risk.

Leases Over One Year Must Be Notarized

Any lease with a term longer than twelve months must be formally acknowledged, essentially notarized, with the landlord’s signature witnessed and stamped by a notary public in the same manner required for deeds.14Washington State Legislature. RCW 59.18.210 – Tenancies From Year to Year or for Term Less Than Life Without that acknowledgment, the lease is not enforceable against anyone other than the two parties who signed it, and a court may treat the arrangement as a month-to-month tenancy. Confirm the notarization before you move in.

Signing, Copies, and Electronic Signatures

Every adult tenant must sign the lease. The landlord then has to provide a fully executed copy to each tenant who signed, and must provide one free replacement copy during the tenancy if a tenant loses theirs.15Washington State Legislature. RCW 59.18.065 – Landlord Copy of Written Rental Agreement to Tenant

Electronic signatures are valid. Washington has adopted the Uniform Electronic Transactions Act, which provides that a signature or contract cannot be denied legal effect solely because it is in electronic form.16Washington State Legislature. Chapter 1.80 RCW – Uniform Electronic Transactions Act Both parties must agree to transact electronically; the tenant cannot be forced onto an e-signature platform. When both sides agree, a lease signed through a service like DocuSign carries the same weight as ink on paper.
