A lot of people moving to Western Washington rent for a year before they buy. It's a smart way to learn the ferry, the bridge and the neighborhoods before committing to one. Washington now has a statewide rent cap, and it makes part of that plan more predictable. But it doesn't protect every renter equally, and the most important question isn't the percentage. It's whether the cap covers the specific unit you're about to sign for. Here's what the law means for someone renting first, checked against the statute and the Department of Commerce in October 2026.
The law and the 2027 number
Washington's rent stabilization law, passed as House Bill 1217, took effect on May 7, 2025, and its core rule is now RCW 59.18.700. For a covered tenancy, a landlord can't raise rent by more than 7% plus the Seattle-area consumer price index, or 10%, whichever is lower, in any 12-month period. The Department of Commerce calculates the figure each summer from the June-to-June change in the Bureau of Labor Statistics' Seattle-area CPI and publishes it for the next calendar year.
For increases taking effect in 2026, the limit is 9.683%. For 2027, Commerce's calculation came to 11.53%, above the ceiling, so the limit for January 1 through December 31, 2027 is 10%. If you sign a lease this fall, your first anniversary lands in 2027, so 10% is the number to plan around, not the 9.683% you'll still see quoted.
Under current law, the cap and its exemptions expire July 1, 2040. That's the date in the statute today, not a promise that the Legislature won't change it sooner.
Does the cap cover the unit you're signing for?
This is the question to ask before you sign. RCW 59.18.710 exempts several kinds of rentals, and two of them are exactly what a newcomer tends to rent.
The first is newer construction. A unit whose first certificate of occupancy was issued 12 or fewer years before the date of the rent increase notice is exempt from the percentage limit. That shiny complex with the fitness room and the move-in special may not be covered, and because the window rolls forward, a building ages into the cap one notice at a time.
The second is owner-occupied rentals. A room where you share a kitchen or bathroom with an owner who lives there, a single-family home where the owner lives and rents out no more than two units or bedrooms, including an ADU, and a duplex, triplex or fourplex where the owner lived in one unit when your tenancy began and still does, are all exempt. Those exemptions don't apply if the owner is a real estate investment trust, a corporation or an LLC with a corporate member.
Regulated affordable housing, including housing authority, public development authority, qualifying nonprofit and tax-credit properties, is also exempt, because other rules already limit its rents. A landlord who raises rent above the limit based on an exemption must include the supporting facts in the written notice. Ask the landlord directly whether the unit is covered and why, and when the building's first certificate of occupancy was issued.
Your first year is protected, if you're covered
For a covered tenancy, the landlord can't raise the rent at all during the first 12 months, whether you sign month-to-month or a fixed-term lease. That's a meaningful protection when you're new to the area and still working out where you'll eventually buy.
Be precise about what it covers. It's the first 12 months of the tenancy, not your first year in Washington, and moving to a different unit starts a new tenancy with its own starting rent. The statute expressly lets a landlord set rent at any amount after a tenant vacates and the tenancy ends, so the cap doesn't limit the asking rent on the next place you look at.
What an increase can look like in year two
Once a covered tenancy passes 12 months, the math is simple. On a $2,000 rent with no earlier increase in the same 12-month window, the 2027 limit allows up to $200 more a month, to $2,200. At the 2026 limit of 9.683%, the same rent could rise by up to $193.66. That's my arithmetic on the published percentages. A maximum isn't automatic, and nothing in the law requires a landlord to raise rent at all.
The limit applies across any 12-month period, not as a fresh allowance every January, so an earlier increase counts against the next one. It also covers recurring charges listed in the rental agreement. Calling part of the rent a fee doesn't move it outside the cap.
When you compare lease options, know that a landlord can't charge more than a 5% difference in rent for the same unit depending on whether you choose month-to-month or a fixed term, and that difference can't push the rent above the increase limit.
Notice rules a newcomer should know
Under RCW 59.18.140, a landlord must give at least 90 days' prior written notice before a rent increase, and the increase can't take effect before your current lease term ends. Subsidized tenancies where rent is based on household income have a 30-day minimum instead. An exempt tenancy still gets the notice, because the cap, the exemption and the notice are separate questions.
Some cities require more. Seattle requires 180 days' written notice for a housing cost increase, and Tacoma moved to 180 days under its Rental Housing Code on January 1, 2026. If you rent in one of those cities first and in Kitsap later, don't assume the same rule follows you.
Late fees have their own rule. Under RCW 59.18.170, a landlord can't charge a late fee for rent paid within five days after it's due. That's a limit on fees, not five extra days. Rent due on the first is still due on the first.
If an increase looks wrong
Check how and when the notice was served, whether it gives enough time under state and local rules, whether it's substantially in the form the statute requires, what exemption it claims and on what facts, and whether the math respects the 12-month window. A casual text saying the rent is going up isn't a notice.
If a covered increase exceeds the limit, the statute has the tenant send the landlord a written demand to bring it down to a lawful amount. A phone call can clear up a misunderstanding, but it isn't the step the law describes. A tenant can also end the agreement before the increase takes effect with at least 20 days' written notice. Suspected violations can be reported to the Washington Attorney General. For an actual dispute, talk to a Washington landlord-tenant attorney before deciding what to pay.
Rent first or buy right away?
The cap makes one part of a rental budget more predictable for a covered tenancy, and that can support a rent-first plan. It doesn't make renting first the automatic answer. Your timeline, your finances, your commute and the actual rent all matter more than the percentage.
Renting first earns its keep when you genuinely don't know which side of the water fits your week. A year of real Tuesdays will tell you more about the ferry, the bridge and the distance to the grocery store than any number of tours. If you already know where you'll work and what you want, the cost of renting and then moving twice deserves a hard look.
Use the cost-of-living page to compare what rent and ownership cost in the towns you're considering, and the budget planner to test both paths. The compare tool will help you choose where to rent so that the year teaches you something useful, and the moving checklist keeps the lease, the move and the eventual purchase in the right order.
