Washington Month-to-Month Lease Agreement

Last Updated: May 29, 2025 by Roberto Valenzuela

A Washington month-to-month rental agreement is a contract (not necessarily in writing) for a tenant to rent property from a landlord, one month at a time, in exchange for a fee (“rent”). The agreement renews monthly, until either party gives proper notice to end it.

Basics of a Washington Month-to-Month Rental Agreement

In Washington, a landlord and tenant create a month-to-month lease by agreeing to rent a property according to acceptable terms. Written agreements are clearer and more reliable in case of disagreement, but month-to-month oral (unwritten) leases are legal.

Parties under a month-to-month lease have full rights under Washington landlord-tenant law. The tenant must use the property in a responsible way and pay rent on time. The landlord must ensure the tenant’s quiet enjoyment of the property. This includes keeping critical features of the property in good working condition.

The main difference between a month-to-month lease and a fixed-term lease is that month-to-month leases can be terminated (with proper notice) by either party, for any reason, without penalty. Landlords also can usually modify terms from one month to the next, again with proper notice. Note that this isn’t always the case in Washington; Seattle, for instance, requires good cause to terminate.

Required Disclosures for Month-to-Month Rentals in Washington

Washington landlords may not rent a property out without making the following disclosures to a potential tenant, as relevant:

  • Landlord’s Name and Address – Landlords must give the tenant their name and address, or that of their authorized agent, to ensure smooth communication and payment of rent in the event of any unusual situations. Typically includes additional contact information for the landlord and authorized agents, such as phone numbers and email addresses.
  • Move-In Checklist – Landlords collecting a security deposit must provide tenants with a move-in checklist to take inventory of the property’s condition upon move-in. A landlord cannot deduct later from a security deposit for any item whose condition wasn’t described in the initial move-in checklist.
  • Fire Safety and Protection Notice – Washington leases must provide information relating to smoke detectors, fire sprinklers, alarms, fire safety systems and evacuation plans. This may be provided as a written notice or checklist, and must include a diagram of emergency evacuation routes.
  • Mold Disclosure – Washington leases must warn about the dangers of indoor mold in the form of a lease disclosure or notice, posted in a conspicuous location.
  • Nonrefundable Fees – Charges not agreed by the tenant in the lease may be refundable upon lease termination. For Washington landlords to charge a non-refundable fee, it must be disclosed and agreed as such in the lease.
  • Seattle Renter’s Handbook and Voter Registration Packet – Seattle landlords must distribute a Renter’s Handbook to new and prospective tenants. This handbook contains tenant rights information and a voter registration packet.
  • Lead-Based Paint – Landlords must provide an EPA-approved disclosure and informational pamphlet to tenants renting any property built before 1978.

Required Notice To End a Month-to-Month Rental in Washington

Washington lets both the landlord or tenant end a month-to-month lease with at least 20 days of advance notice. For many parts of the state, it’s valid to end a month-to-month lease for any reason that isn’t landlord retaliation. However, Seattle has specific requirements for good cause to end a month-to-month lease.

Washington requires written notice to end a month-to-month lease.

Required Notice To Raise the Rent on a Washington Month-to-Month Lease

Washington requires at least 60 days of advance notice in most cases before raising the rent. The city of Seattle requires 180 days. In both cases, subsidized rentals only require 30 days of notice before a change in the rent.

Washington requires written notice to raise the rent.

Eviction in Washington Month-to-Month Rentals

Washington tenants may get evicted if they violate lease terms or stay on the property after the notice period allowed by a valid termination. Evictions in Washington typically take one to three months, sometimes longer.
