Washington's rent-stabilization law (HB 1217, effective May 7, 2025) requires at least 90 days' written notice for ANY rent increase and caps most annual increases at 7% + CPI (10% max). Specific notice forms are required, and cap exemptions (e.g. newer buildings) must be claimed in the notice — see the WA Dept. of Commerce HB 1217 landlord resource center.
