1. Rent Increase Rules in Washington for 2026

Washington has a statewide rent cap for 2026. Under House Bill 1217, signed into law in May 2025, annual rent increases for most residential properties are limited to 7% plus inflation, or 10%, whichever is lower.

For 2026, the Washington State Department of Commerce has set that maximum at 9.683%. The limit applies from January 1 through December 31, 2026, and the Department recalculates and publishes a new figure each year based on Seattle-area inflation data.

How the cap works

  • The cap applies after the first 12 months of a tenancy. You cannot raise rent during the first year.
  • The maximum increase for 2026 is 9.683%, and it applies to increases that take effect between January 1 and December 31, 2026.
  • The Department of Commerce updates this figure each year, so the limit for future years will change with inflation.
  • Certain property types are exempt, including some newer construction and certain owner-occupied buildings.

What this means for landlords

  • You must provide proper written notice before any rent increase. The statewide requirement is 90 days, and Seattle requires 180 days.
  • You must clearly document and deliver the increase, including the new amount and its start date.
  • You cannot exceed the 9.683% cap for 2026 regardless of rising expenses, so renewal and pricing decisions should begin earlier.
  • If you operate in Seattle or another city with stronger tenant protections, you must also comply with all local ordinances, which can affect timelines and processes.


Seattle, in particular, has additional tenant-protection laws that go beyond state requirements. The most up-to-date information can always be reviewed through the Washington State Legislature.

2. Updated Notice Requirements for Rent Increases

Washington now requires landlords to give advance written notice before raising rent. Most cases require:

  • At least 90 days notice before any rent increases, up from the previous 60-day requirement
  • Use of the standardized rent increase notice form published by the Washington State Department of Commerce
  • Clear written documentation of the new amount and start date

Seattle already required 180 days notice for certain increases, so Seattle landlords must follow whichever law is more protective for tenants.

3. New Rules on Fees, Deposits, and Move-In Costs

Washington 2026 rental law also clarifies limits and requirements on:

  • Security deposits
  • Holding fees
  • Non-refundable fees
  • Payment structures at move-in

Landlords must:

  • Provide a written deposit statement
  • Give tenants a move-in condition checklist
  • Store deposits in a separate account
  • Return deposits within the required time frame

 

Seattle landlords must also comply with the RRIO program, which can be reviewed at Seattle RRIO.

4. Updated Screening and Application Rules

Tenant screening in Washington is shaped by existing state law and by local ordinances, several of which restrict how landlords can evaluate applicants. These requirements are separate from the 2026 rent and fee changes under HB 1217, but they remain part of staying compliant when filling a vacancy.

Landlords must follow rules related to:

  • Screening fee disclosures
  • Application records
  • Criminal history screening limits
  • Adverse action notices
  • Income and credit evaluation requirements

For Seattle rentals, the Fair Chance Housing Ordinance still applies in part. Following a 2023 federal court ruling, Seattle no longer enforces the rule that barred landlords from asking about an applicant’s criminal history. The city does still enforce the rest of the ordinance, including the limits on requiring disclosure of criminal history and on taking adverse action based on it. Details are available on the Seattle Fair Chance Housing page.

5. Required Disclosures for 2026

Washington landlords must provide tenants with certain disclosures at move-in and renewal.

This includes:

  • Safety information
  • Ownership or management details
  • Utilities billing information
  • Deposit documentation
  • Lease term and rent amount
  • Notice of rights and responsibilities

For landlords who prefer a legally compliant leasing process, SJA Property Management prepares and delivers all required documentation on your behalf.

6. Eviction and Termination Rules in 2026

Washington strengthened eviction standards, requiring:

  • Clear written notice
  • Reason-based termination
  • Strict adherence to timelines
  • Proper delivery of documentation

The state continues to support mediation programs, and local courts increasingly require evidence of communication and attempts to resolve issues before filing.

Noncompliance can delay the eviction process and result in additional penalties.

7. How the 2026 Law Impacts Your Rental Strategy

These new rules mean landlords need to plan ahead more carefully.

The Washington 2026 rental law affects:

  • Renewal strategy
  • Cash flow planning
  • Rent increase timing
  • Long-term returns
  • Maintenance and capital planning
  • Selling vs. holding decisions

For example:

  • If you want to increase rent, you must plan months earlier
  • If your expenses rise faster than the rent cap, budgeting becomes critical
  • Tenant retention becomes more valuable
  • Lease structure must be more detailed and compliant

Landlords who treat their rental as a structured business will adjust smoothly. Those who self manage without support often face compliance issues.

8. How Landlords Can Stay Fully Compliant in 2026

To operate successfully under Washington 2026 rental law, landlords should:

✓ Document everything

Rent increases, notices, communication, deposit records, screening criteria, and maintenance logs.

✓ Use attorney reviewed leases

Generic leases are no longer enough.

✓ Give notice earlier than required

This protects you from timing mistakes.

✓ Understand both state and city rules

Seattle, Bellevue, Redmond, Kirkland, Renton, and Tacoma may all have different local requirements.

✓ Work with a property manager
