Seattle Rent Increase Rules 2026: What Washington Law Allows

Since May 2025, Washington has capped annual rent increases statewide, and Seattle adds the longest increase notice period in the state and relocation help for eligible renters. In the city of Seattle, about 204,500 of 363,500 occupied homes, or 56.3 percent, are rented, according to the U.S. Census Bureau’s 2020 to 2024 American Community Survey (Homzora Seattle dataset, Table B25003). The median gross rent is $2,030 a month (Homzora Seattle dataset, Table B25064).

Quick answers

• 2026 cap: 9.683 percent for increases in 2026 (Washington Department of Commerce, 2026 rent cap announcement).
• Formula: 7 percent plus inflation, or 10 percent, whichever is less, in any 12 months (RCW 59.18.700).
• Seattle notice: at least 180 days in writing (Renting in Seattle, Receiving notice from your landlord).
• Relocation help: for eligible households after increases of 10 percent or more (Renting in Seattle, Economic Displacement Relocation Assistance).

Washington’s rent cap

House Bill 1217 limits rent increases in any 12 month period to 7 percent plus the consumer price index, or 10 percent, whichever is less, and bars any increase during the first 12 months of a tenancy (RCW 59.18.700). The Department of Commerce set the 2026 cap at 9.683 percent, in effect January 1 through December 31, 2026 (Washington Department of Commerce, 2026 rent cap announcement), and lists the 2027 cap at 10 percent (Washington Department of Commerce, HB 1217 landlord resource center).

Who is exempt

Exemptions include units whose first certificate of occupancy was issued 12 years or less before the notice date, public housing authority units, many nonprofit and income restricted units, and certain owner occupied homes and small multifamily buildings (RCW 59.18.710).

Remedies

A tenant charged an unlawful increase may recover the excess rent and additional damages, and the attorney general may seek penalties of up to $7,500 per violation (RCW 59.18.700).

Notice periods

State law requires at least 90 days’ written notice before a rent increase, and the increase cannot take effect before the current term ends (RCW 59.18.140). The notice must follow the form required by law (RCW 59.18.720). Seattle requires at least 180 days’ written notice, and no increase can take effect while the unit fails the city’s rental inspection standards (Renting in Seattle, Receiving notice from your landlord).

Seattle relocation assistance

Seattle’s Economic Displacement Relocation Assistance helps households with income at or below 80 percent of area median income who receive an increase of 10 percent or more in a 12 month period and who move out, or give notice to move, before it takes effect (Renting in Seattle, Economic Displacement Relocation Assistance). The city’s housing provider page describes the payment as three times the current monthly housing cost, paid by the city and reimbursed by the landlord (Renting in Seattle, EDRA for housing providers).

Retaliation

A landlord may not retaliate against a tenant’s good faith complaint or exercise of legal rights by raising rent, reducing services, or evicting (RCW 59.18.240). An action within 90 days of the tenant’s act is presumed retaliatory, though a rent increase whose notice states reasonable grounds is not (RCW 59.18.250).

Late fees

No late fee may be charged if rent is paid within 5 days of the due date (RCW 59.18.170).

Just cause

Washington requires a listed cause to end most periodic tenancies, and a wrongful eviction can cost a landlord the greater of actual damages or three times monthly rent (RCW 59.18.650).

Fair housing

The federal Fair Housing Act prohibits discrimination in rental terms because of race, color, religion, sex, familial status, national origin, or disability (42 U.S.C. § 3604). HUD accepts complaints (HUD, File a Complaint).

If you cannot afford the increase

• Ask about a different lease length. Some landlords price longer terms lower to avoid turnover.
• Ask about a smaller unit from the same owner.
• Compare total monthly cost, including parking, utilities, and fees.
• Contact 211 to ask about rental assistance programs in your area (211.org).
• Decide before your notice deadline, so you can give proper notice if you move.

At a rent of $2,030, the median gross rent used in this guide, a 5 percent increase adds about $102 a month, or about $1,218 a year. Comparing that annual figure with the cost of moving, including a new deposit and moving expenses, often clarifies the decision.

Build your evidence file

Landlord and tenant disputes are usually decided by documents. Keep these together from the day you sign:

• The signed lease, every addendum, and every renewal.
• Receipts or bank records for the deposit and each rent payment.
• Dated photos and video of every room at move in and move out.
• Copies of every repair request and the landlord’s replies.
• Every notice you send or receive, with proof of delivery.

Keep copies somewhere other than your phone, such as an email to yourself, so they survive a lost device.

Before you sign your next lease

• Ask who owns and who manages the property, and get contact details in writing.
• Read the clauses on early termination, subletting, renewal, late fees, and notice before you sign.
• Confirm the deposit amount, where it will be held, and how it will be returned.
• Walk through the unit, note existing damage in writing, and keep a signed copy.
• Ask how much notice the landlord gives before a rent increase or a non renewal.

Help in Seattle

The City of Seattle’s Renting in Seattle helpline answers questions at 206.684.5700 (Renting in Seattle). The Tenants Union of Washington State runs a Tenants Rights Hotline at 206.723.0500 (Tenants Union of Washington State, Tenants Rights Hotline), and WashingtonLawHelp.org publishes free legal information for renters (WashingtonLawHelp.org, Housing). Rent and tenure figures in this guide are free to download from the Homzora Seattle data library.

Questions to ask before you renew

• Is the renewal rent fixed for the entire term?
• Is there a lower price for a different lease length?
• Are new resident specials available to renewing residents?
• Does the renewal change any fees, including late fees, parking, or amenity charges?
• If I decline, by what date must I give notice?

Get the answers in writing. A renewal is a new contract, and anything not written into it is difficult to enforce later.

Read the renewal offer line by line

A renewal offer is more than a rent number. Look for changes to parking, pet rent, trash, pest control, amenity fees, utility billing, renter’s insurance requirements, and the late fee clause. Ask for a written comparison of your current total monthly cost and the proposed total, and compare that total, not just base rent, with other rentals.

How to compare listings

• Match the bedroom count, size, and neighborhood as closely as you can.
• Note whether utilities, parking, or amenities are included.
• Record the date you saw each listing and any move in specials.
• Save screenshots, since listings change quickly.
• Bring three to five comparisons to the conversation with your landlord.
