Washington Month-to-Month Lease Agreement

Last Updated: December 12, 2023 by Roberto Valenzuela

A Washington month-to-month rental agreement is a contract (not necessarily in writing) which allows a tenant to rent property from a landlord, for one month at a time, in exchange for a fee (“rent”). The rental 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 rental agreements are clearer and legally stronger, but oral leases are legal in a month-to-month context.

Parties under a month-to-month lease enjoy 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 keep essential features of the property in habitable condition, and protect the tenant’s quiet enjoyment of the lease.

The main difference between a month-to-month lease and a fixed-term lease is that month-to-month leases usually 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 enable smooth communication of legal notice.
  • Move-In Checklist – Landlords must provide tenants with a move-in checklist to take inventory of existing property damage before move-in.
  • Fire Safety and Protection Notice – Washington landlords 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 requires all landlords to provide information 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 terminate a month-to-month lease with at least 20 days of advance notice. For many parts of the state, any reason that isn’t landlord retaliation is a legal and valid grounds for ending a month-to-month lease. 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 before most rental increases, delivered in writing. The city of Seattle requires 180 days. In both cases, subsidized rentals only require 30 days of notice before a change in the rent.

Eviction in Washington Month-to-Month Rentals

Washington tenants may face eviction for violating a month-to-month lease or remaining on the property after the notice period allowed by a valid termination. Evictions in Washington typically take one to three months, sometimes longer.
