What Landlords Need to Know About HB 1217: Washington’s New Statewide Rent Cap

If you own rental property in Washington, there’s a new law on the books you need to understand—House Bill 1217, effective as of May 7, 2025. This legislation introduces the first statewide rent cap in Washington’s history, and it’s going to change the way landlords approach lease renewals, pricing strategies, and long-term planning.

Let’s break it down: what HB 1217 does, why it was passed, how it compares to local laws like Seattle’s, and what it means for you as a property owner.

Washington HB 1217 in Plain Language

HB 1217 limits most residential rent increases across Washington to:

7% plus inflation (Consumer Price Index)
Capped at 10% annually
Applies to both month-to-month and fixed-term leases
90 days’ written notice is now required for any rent increase
No rent increases are allowed during the first 12 months of a tenancy

The cap is tied to inflation, but the state has made it simple: for the rest of 2025, the maximum allowed increase is 10%, according to the Department of Commerce.

Are There Exemptions to HB 1217?

Yes. HB 1217 does not apply to:

Newly constructed properties (less than 12 years old)
Owner-occupied small properties (duplexes, triplexes, or fourplexes where the owner lives on-site)
Affordable housing regulated by other federal, state, or local rules (e.g. public housing authorities or nonprofit providers)

If your property falls into one of these categories, you may still have more flexibility—but be sure to document and verify your exemption before issuing a rent increase.

What About Seattle and Other Local Rules?

Seattle already had strict rent notice and tenant protection rules—and many still apply in addition to HB 1217:

180 days’ written notice is still required for rent increases in Seattle
Rent increases of 10% or more trigger Economic Displacement Relocation Assistance (EDRA) requirements
Rent increases are prohibited in units that fail maintenance inspections under the “Carl Haglund Law”

HB 1217 sets the ceiling statewide, but cities like Seattle can still enforce stricter procedural rules—especially when it comes to notice and tenant rights.

Why This Law Passed

HB 1217 came in response to growing political pressure over housing affordability. Rent hikes of 20%, 30%, or more in some areas had pushed working-class tenants to the brink, with little legal recourse outside cities like Seattle. Advocates framed the law as a way to introduce predictability and prevent price-gouging, especially in hot markets.

Supporters say the 10% cap is generous enough to cover inflation and rising costs, while discouraging extreme year-over-year spikes. Critics argue it could discourage landlords from maintaining or improving properties and push investment capital out of the rental market altogether.

Landlord Perspective: What to Watch For

Many landlords are understandably frustrated. The law reduces flexibility in adjusting rents to market levels, especially in areas where operating costs have risen faster than inflation. And because it applies statewide, it affects smaller markets that never experienced the dramatic rent spikes seen in cities like Seattle.

You’ll want to be especially careful about:

Tracking lease start dates to avoid raising rent during the first year
Providing proper 90-day notice (or 180 in Seattle)
Documenting your exemptions, if applicable
Adjusting business plans that relied on faster rent growth or repositioning strategies

The concern is that this could trigger a chilling effect: landlords might feel pressure to max out the allowable increase each year “just in case,” or exit the rental market entirely—especially smaller owners with thin margins.

Is HB 1217 the End of the Story?

Unlikely. HB 1217 is Washington’s first statewide rent cap, but it’s unlikely to be the last word in housing reform. Tenant advocates are already pushing for stricter limitations, vacancy controls, and further curbs on evictions.

For now, HB 1217 strikes what lawmakers call a “moderate” balance—protecting tenants from the most extreme rent shocks without fully implementing the kind of hard rent control seen in places like New York or California.

What You Should Do Now

If you’re a landlord in Washington:

Review your current lease terms
Identify which properties are exempt
Adjust your renewal workflows to align with the 90-day rule (or 180 in Seattle)
Consider consulting a local property manager or attorney for guidance on compliance

And most importantly, stay informed. HB 1217 is likely the start of a broader shift in how Washington regulates rental housing.
