Increasing Rents in Washington State

As always, this is informational and not legal advice. Please reach out to your attorney before making any decisions!

Outside of Seattle:

Rent increases are allowed with 60 days notice IF not located in Seattle, Auburn, Kenmore, and Unincorporated King County.

In Auburn, any total rent increase greater than 5% requires 120 days notice.

In Kenmore, any total rent increase greater than 10% requires 90 days notice.

In Unincorporated King County, any total rent increase greater than 3% requires 120 days notice.

City of Seattle:

Any rent increase taking effect after November 8, 2021 requires 180 days’ notice.

You must then also offer the lease extension or a just cause reason for not renewing between 60-90 days prior to the lease end date.

If the rent increase is for 10% or more over the lowest rate in the past 12 months, the notice of increase must either be delivered to each adult at the unit by either hand-delivery or mailing both by certified mail with return receipt requested and by regular US mail. The notice must also include a packet about the new economic displacement relocation assistance program, which may charge the Lessor up to three month’s rent for tenant relocation expenses.
