Washington· Answer
How much advance notice does Washington require to raise rent?
Short answer
Washington HB 1217 (2024) requires 90 days advance notice for any rent increase, prohibits any increase during the first 12 months, and caps annual increases at the lower of CPI + 7% or 10% flat. Buildings under 12 years old are exempt. The rent cap framework sunsets July 1, 2040.

Honest limits
This is an informational answer based on RCW 59.18.140 (90-day advance notice for any rent increase, HB 1217) as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a Washington-licensed attorney.
