If you’re a landlord in Washington State, the question isn’t can you raise rent anymore—it’s how you do it legally under the new HB 1217 rules. With the recent signing of House Bill 1217 into law, rent control is now a statewide policy, and the way landlords handle rent increases will need to change immediately.

This guide explains exactly what you can and cannot do under the law, how to stay compliant, and how to move forward without risking legal issues or tenant fallout.

How to Raise Rent Legally in WA Under HB 1217

1. Follow the New Rent Increase Caps

Under HB 1217, rent increases are capped at 7% plus the Consumer Price Index (CPI), or 10% total per year, whichever is lower.

  • For example, if CPI is 3%, you can raise rent by no more than 10%.
  • If CPI is only 1.5%, you are limited to 8.5% total.

For manufactured home communities, the cap is even tighter: 5% annually, regardless of CPI.

2. Provide the Correct Notice

Notice periods under HB 1217 are now longer than before:

  • 180 days’ written notice for rent increases of 3% or more
  • 90 days’ written notice for increases under 3%

The notice must be:

  • In writing
  • Delivered in a legally accepted format

Include the effective date, new rental amount, and a statement referencing the applicable rent cap law.

3. Check for Exemptions Before You Act

Certain properties are exempt from the rent cap rules, including:

  • Properties issued a certificate of occupancy within the last 12 years.s
  • Specific types of affordable or nonprofit-owned housing

Even if your property qualifies, documentation will likely be required.

What Happens If You Don’t Comply?

The penalties for violating HB 1217 are serious. Landlords could face:

  • Fines of up to $7,500 per violation
  • Private lawsuits initiated by tenants
  • Investigations and enforcement actions from the Attorney General’s Office

Tenants also have the right to:

  • Break their lease with 20 days’ notice if the increase exceeds legal limits
  • Seek legal damages and recovery of attorney’s fees

Compliance is not optional. This law is enforceable now, and enforcement mechanisms are active.

Tips for a Smooth, Legal Rent Increase in 2025

  • Run a rent analysis first. Don’t assume your rent is under market—data is key.
  • Communicate with your tenants early. Transparency builds trust and avoids conflict.
  • Keep everything in writing. Notices, rent histories, and CPI references should be documented.
  • Work with a property manager. Professionals already have templates, systems, and training to stay compliant.

What HB 1217 Doesn’t Stop You From Doing
