60 days rent-increase notice.
Landlords must give at least 60 days' written notice before raising rent. A 2025 statewide law caps most annual increases at 7% plus CPI, not to exceed 10%, with exemptions for newer buildings.
What this means for you: Washington joined the small group of states with a statewide rent-increase cap. Check whether your building's age exempts it.
Your next step: Verify you received 60 days' notice and that the increase fits within the cap if your unit is covered.
