Introduction
A residential lease agreement is a legally binding contract between a landlord and a tenant that sets the terms under which the tenant rents the landlord's property, including the rent amount, the length of the tenancy, the security deposit, each party's responsibilities, and how the tenancy ends. In Washington the lease is governed by the Residential Landlord-Tenant Act (RLTA), Chapter 59.18 RCW. Washington sets no statutory cap on the security deposit itself, though a holding fee charged just to reserve a unit before move-in cannot exceed 25 percent of the first month's rent (RCW 59.18.253). The landlord must hold the deposit in a trust account and, within 30 days after the tenancy ends, give a full and specific written statement of any amount kept, or the landlord becomes liable for the full deposit (RCW 59.18.280). A landlord cannot even collect a deposit without first giving the tenant a written move-in checklist describing the unit's condition (RCW 59.18.260). Washington also requires the landlord to give tenants mold-hazard information and a written fire safety and smoke detector disclosure (RCW 59.18.060). To enter the unit, the landlord must give the tenant at least two days' written notice, or one day's notice to show the unit to a prospective tenant or buyer (RCW 59.18.150). Since 2025, most Washington tenancies are also subject to statewide rent stabilization limiting rent increases and requiring just cause to end a tenancy. Attorney review is available as an option before you sign.

Washington Requirements for Residential Lease Agreement
A landlord may not collect a security deposit unless the rental agreement is in writing and a written checklist describing the condition of the premises is given to the tenant at move-in (RCW 59.18.260). The deposit itself must be held in a trust account, and the landlord keeps any interest unless the parties agree otherwise in writing (RCW 59.18.270).
Within 30 days after the tenancy ends and the tenant vacates, the landlord must give a full and specific written statement of the basis for keeping any part of the deposit, with supporting documentation, and refund the remainder (RCW 59.18.280). Washington sets no statutory cap on the deposit amount itself for a standard rental.
The landlord must give new tenants written information, provided or approved by the Washington Department of Health, about the health hazards associated with exposure to indoor mold, at the time the lease is signed (RCW 59.18.060(13)).
The landlord must give tenants written notice disclosing fire safety and protection information, including that the unit is equipped with a smoke detection device as required by RCW 43.44.110 (RCW 59.18.060(12)).
The landlord must give the tenant at least two days' written notice of intent to enter and may enter only at reasonable times. To show the unit to a prospective tenant or buyer, only one day's notice is required, and the tenant may not unreasonably withhold consent (RCW 59.18.150).

A landlord generally needs a just cause listed in RCW 59.18.650 to end an ongoing tenancy.
Frequently Asked Questions
A Washington lease should name the landlord and tenant, describe the rental address, state the rent amount and due date, the term, and the security deposit amount and how it is held.

No. A Washington residential lease is a private contract between landlord and tenant and does not need to be notarized or witnessed to be valid and enforceable under the Residential Landlord-Tenant Act, Chapter 59.18 RCW.
No, except in an emergency. A Washington landlord must give the tenant at least two days' written notice before entering, or at least one day's notice to show the unit to a prospective tenant or buyer, and may only enter at reasonable times (RCW 59.18.150).
Washington landlords must give tenants written information about the health hazards of indoor mold and a written fire safety and smoke detector notice, both required by RCW 59.18.060, plus federal lead-based paint disclosures for housing built before 1978.

A tenant can end a Washington month-to-month tenancy by giving the landlord 20 days' written notice before the end of a rental period (RCW 59.18.200).

A Washington landlord cannot charge any late fee if the tenant pays rent within five days of its due date (RCW 59.18.170). There is no statutory cap on the amount of a late fee once that five-day window has passed, so the lease should state the fee clearly and keep it reasonable.
