Key Takeaways
Washington's maximum rent increase for covered residential properties is 9.683% in 2026, although some rentals qualify for exemptions.
Landlords should review the property's current rent, operating costs, market conditions, and lease timing before deciding on an increase.
Washington generally requires at least 90 days' written notice before a residential rent increase can take effect.
Clear communication can help residents understand an adjustment, but an informal conversation does not replace the required written notice.
Washington's rent increase rules changed significantly with the passage of House Bill 1217 in 2025. For rental property owners, that means planning an increase now requires careful attention to both the amount being charged and the timing of the adjustment.
Determining an appropriate rental rate, preparing early for a lease renewal, and communicating the change professionally can all influence how smoothly the process goes.
SunWorld Group Property Management works with rental property owners throughout Southwest Washington, including Vancouver, where these decisions are now an important part of managing a rental investment.
What Washington's Rent Increase Law Means for Landlords
House Bill 1217 established statewide restrictions on residential rent increases. For covered properties, the maximum increase is based on 7% plus the Consumer Price Index or 10%, whichever is lower.
For increases taking effect in 2026, the Washington State Department of Commerce established a maximum increase of 9.683%.
This percentage is a ceiling, not a target. An owner does not have to increase rent by the maximum amount allowed.
Washington also generally prohibits increases during the first 12 months of a tenancy and restricts how frequently rent can be increased.
Certain properties and rental arrangements may qualify for exemptions, including some newer construction and qualifying owner-occupied small multifamily properties.
Because exemption requirements can be specific, property owners should confirm that an exemption applies before relying on it.
Plan a Rent Increase Before the Renewal Date
A rent adjustment should start with the property rather than the maximum percentage allowed by law.
Review the existing rental rate alongside current market conditions and the property's operating expenses. Maintenance, insurance, owner-paid utilities, and other expenses may affect whether an adjustment makes financial sense.
Lease timing matters as well. In Washington, landlords are typically required to give tenants a minimum of 90 days' notice before a residential rent increase takes effect.
Waiting until a renewal is approaching can limit an owner's options, even when an increase would otherwise be permitted.
Creating a consistent review process can help. Rather than making rental rate decisions at the last minute, evaluate the property well before important lease dates and document the factors that influenced the proposed adjustment.
How to Explain a Rent Increase to a Resident
Once you've determined that an increase is appropriate and complies with applicable requirements, consider how you will communicate it.
A resident should understand the new rental rate, when it will take effect, and what they need to do next. Providing additional context can also make the change easier to understand.
For example, if operating expenses have increased or the existing rent is no longer aligned with relevant market conditions, explain that clearly without overwhelming the resident with unnecessary details. Keep the discussion factual and focused on the property.
A courtesy phone conversation before sending the notice may also be helpful, particularly with a long-term resident. It gives you an opportunity to explain the adjustment before the formal notice arrives and allows the resident to ask questions.
However, that conversation is not the rent increase notice. Washington landlords still need to follow the applicable written notice requirements.
Keep the Conversation Professional
Rent increases can lead to questions, so be prepared to explain how the decision was made without turning the discussion into a debate over every expense associated with the property.
Listen to reasonable concerns and keep the conversation centered on the lease and rental property. Depending on your investment goals and the circumstances, you may also evaluate renewal terms or other options rather than approaching every tenancy in exactly the same way.
Consistency is important. Establishing a process for reviewing rental rates, documenting decisions, providing required notices, and communicating changes can help owners manage renewals more effectively across multiple properties.
Make Sure the Written Notice Is Compliant
A conversation with a resident can improve communication, but compliance ultimately depends on following Washington's formal requirements.
The state generally requires at least 90 days' written notice before a covered residential rent increase takes effect. Washington law also establishes requirements for the information that must appear in the notice.
Avoid relying on an old notice template simply because it was acceptable in previous years. Washington's rules have changed, and the maximum allowable increase can also change annually.
Before delivering a notice, confirm the current requirements, applicable limit, lease terms, effective date, and whether the property qualifies for an exemption. For property-specific legal questions, consult a qualified Washington landlord-tenant attorney.
Conclusion
A successful rent adjustment starts well before the notice is delivered. Property owners should evaluate the financial needs of the rental, consider current market conditions, review upcoming lease dates, and approach resident communication with a clear plan.

Frequently Asked Questions
Should Landlords Automatically Raise Rent Every Year?
Not necessarily. An annual increase may be permitted, but that does not mean it is always the best decision for the property. Consider the current rental rate, operating expenses, relevant market conditions, lease timing, and your long-term investment objectives.
An owner may determine that an adjustment is appropriate, that a smaller increase makes sense, or that maintaining the current rate better supports the property's overall strategy.
How Should I Determine a New Rental Rate?
Start by evaluating the property's existing rent rather than simply applying the maximum percentage permitted by law. Compare the property with relevant rentals in the local market while considering its condition, features, operating expenses, and lease terms.
The goal is to establish a rental rate that makes sense for the individual property and your investment objectives while remaining within any applicable legal limits.
Should I Call a Resident Before Sending a Rent Increase Notice?
A courtesy conversation can be useful, especially when you want to provide context before the resident receives the formal notice. You can explain that the rental rate has been reviewed, state the proposed change, and answer reasonable questions.
However, a phone call does not replace the written notice required under Washington law. Treat the conversation as a communication tool rather than part of the formal notice process.
What Should I Say When Explaining a Rent Increase?
Keep the explanation concise and factual. Tell the resident what the new rental rate will be, when it is expected to take effect, and provide relevant context for the decision when appropriate. This could include changes in property expenses or current market conditions.
Avoid making the conversation unnecessarily complicated. Clear information and professional communication are generally more useful than attempting to justify every individual cost associated with owning the rental.
What Should I Review Before Renewing a Lease?
Review the current lease, rental rate, upcoming renewal date, property expenses, maintenance needs, and relevant market conditions.
If you're considering a rent adjustment, determine what notice requirements and rent increase restrictions apply early enough to meet the required timeline.
