After months of debate and legislative revisions, House Bill 1217 (HB 1217) has officially been signed into law in Washington state. This sweeping 2025 rent control law represents a major shift for landlords, tenants, and property managers alike.

Whether you own one rental property or manage an entire portfolio, this is a moment you can’t afford to ignore.

In this article, we’ll provide a clear, concise HB 1217 summary, walk through the core changes, and explain exactly what Washington landlords need to do now to stay compliant, profitable, and protected.

What Is HB 1217?

HB 1217 is now Washington’s first statewide rent control law, making it the third state in the U.S. (after California and Oregon) to pass this kind of legislation.

Effective immediately as of May 8, 2025, this bill introduces new limits on rent increases, stricter notice requirements, and enforcement powers for the Attorney General.

Key Features of Washington’s Rent Control Law

Here’s what’s included in HB 1217:

Rent Increase Cap

Landlords can now only raise rent by the lesser of:

  • 7% + June 1st Consumer Price Index (CPI) of each year OR
  • 10% total per year

This applies to most residential rentals unless specifically exempt (see below). CPI is published by the Washington State Department of Commerce

Notice Requirements

  • 90 days’ notice is required for any increase amount unless local jurisdiction requires a longer notice period. Landlords must comply with longer notice period.
  • Applies to both lease renewals and month-to-month tenants
  • Must be served in the manner prescribed by RCW 59.12.040 including certified mail for rent increases taking effect on or after July 27, 2025

Tenant Protections

Tenants may terminate a lease any time prior to the effective date of the rent increase without penalty with a 20-day written notice if a rent increase exceeds the legal cap

Enforcement & Penalties

The Washington State Attorney General’s office has new powers to:

  • Investigate violations
  • Pursue civil penalties (up to $7,500 per violation)
  • Enforce compliance with court action

Which Properties Are Exempt from HB 1217?

Not all rentals fall under the new rules. You may be exempt if:

  • Your rental was issued a certificate of occupancy within the last 12 years
  • Your property is classified as affordable housing with restricted rent
  • Your unit is owned by a qualifying nonprofit housing provider

If you’re unsure about your exemption status, now is the time to check—and document it clearly.

What Landlords Must Do Now

If you own or manage property in Washington, here’s how to stay ahead: 

Update Your Rent Increase Strategy 

Relying on large rent hikes to catch up on rising costs? That may no longer be an option. Factor CPI and cap thresholds into your annual planning. 

Review Lease Templates and Notices

You must use the rent increase notice in substantially the form provided in the new law.

Document Everything

Store copies of:

  • Rent increase notices for each tenant in the unit
  • Copy of envelope with the certified mail label
  • Proof of CPI data used in your calculation
  • Tenant correspondence
  • Exemption documentation (if applicable)

Communicate With Tenants Early

Avoid confusion, disputes, and complaints by proactively explaining any rent changes with transparency and empathy.
