According to legislation passed in the 2025 session, the legislature passed Residential Rent Control as well as Manufactured Housing Rent Control – which are two separate “lids.”
As far as the maximum rent increase that may take effect during January to December 2027 under RCW 59.18.770, rent increases will be up to 7% plus the Consumer Price Index or 7% whichever is less.
Once the June 2026 CPI is released, landlords will know the maximum rent increases that may take effect from January to December 2027.
The CPI is published by the Washington State Department of Commerce | Web Link: Landlord Resource Center
