Washington Security Deposit Laws

December 23, 2025 By Upkeep Media

Gregory-Property-Management

Key Takeaways

  • Written documentation is mandatory: Washington landlords may only collect a security deposit with a written lease and a signed move-in checklist. Without these, landlords lose the right to withhold any portion of the deposit.
  • Deposits must be properly stored: All security deposits must be held in a Washington-based trust account, and tenants must receive written notice identifying where the deposit is held.
  • Strict rules govern deductions and refunds: Deposits may only be withheld for lawful reasons such as unpaid rent or damage beyond normal wear and tear, and any remaining balance must be returned with an itemized statement within 30 days.
  • Noncompliance can be costly: Failing to follow Washington’s security deposit laws may require landlords to return the full deposit and could expose them to additional damages, court costs, and attorney fees.

For a landlord, collecting a security deposit from your tenant offers important financial protection throughout the lease and at move-out. A properly handled security deposit can reduce disputes, help cover losses, and provide peace of mind when managing a rental property in Washington. 

Washington State has specific laws that govern how security deposits must be collected, documented, stored, and returned. Failing to follow these requirements can expose landlords to penalties and legal disputes.

A Guide to Washington’s Security Deposit Law

Understanding Washington’s security deposit requirements is essential for protecting your investment and staying compliant with state law.

Washington Security Deposit Limit

Unlike many states, Washington does not set a maximum limit on how much a landlord can charge for a security deposit. This means landlords may charge any amount, as long as the deposit is reasonable and clearly stated in the lease agreement.

Washington landlord-tenant law places important conditions on collecting a deposit. A security deposit may only be charged if there is a written rental agreement in place. 

In addition, the landlord must complete a move-in checklist documenting the condition of the unit before collecting the deposit. Without this checklist, a landlord loses the legal right to withhold any portion of the deposit later, even if damage occurs.

Note that local jurisdictions can establish their own limits to security deposits. For example, Seattle limits the maximum security deposit to one month’s rent including any non-refundable fees.

Nonrefundable Fees

Washington allows landlords to charge nonrefundable fees, but only under specific conditions. Any nonrefundable fee must be clearly disclosed in writing and explicitly identified as nonrefundable in the rental agreement. 

Common examples include cleaning fees or administrative fees. If a fee is not clearly labeled as nonrefundable in the lease, it will legally be treated as a refundable security deposit, regardless of how the landlord intended it to be used. Transparency in lease language is critical to avoid disputes.

Storing a Tenant’s Deposit in Washington

Washington has strict rules regarding how security deposits must be stored. Landlords are required to place all security deposits into a trust account at a financial institution located in Washington State.

The tenant must be informed in writing of:

  • The name of the bank or financial institution holding the deposit
  • The account number or a clear identifier for the trust account

Unlike some states, Washington does not require landlords to pay interest on security deposits unless the lease specifically states otherwise. However, failure to properly place the deposit in a trust account can result in serious legal consequences.

Written Notice After Security Deposit Receipt

In Washington, landlords must meet specific written documentation requirements when collecting a security deposit. A landlord may only charge a security deposit if there is a written rental agreement in place.

Before collecting the deposit, the landlord must also provide a written move-in checklist that clearly describes the condition and cleanliness of the rental unit. This checklist must be signed by both the landlord and the tenant, and the tenant must be given a copy. 

Without a proper checklist, a landlord may lose the right to withhold any portion of the security deposit for damages later.

Landlords must also provide the tenant written notice of where the deposit is being held, including the name of the financial institution holding the trust account and the related account identification details required by Washington law.

Reasons to Withhold a Tenant’s Security Deposit in Washington

Washington law allows landlords to withhold part or all of a tenant’s security deposit for specific reasons, provided the deductions are reasonable and documented.

Common lawful reasons include unpaid rent, unpaid utilities that the tenant was responsible for, costs to repair damage beyond normal wear and tear, and excessive cleaning required to return the unit to its move-in condition.

Landlords may not withhold deposits for normal wear and tear or for conditions that existed prior to the tenant moving in. The move-in checklist plays a crucial role in determining what qualifies as tenant-caused damage versus pre-existing issues.

Walk-Through Inspections

Washington law requires landlords to conduct a move-in inspection and complete a detailed checklist before collecting a security deposit. This inspection protects both parties by creating a clear record of the unit’s condition at the beginning of the tenancy.

Gregory-Property-Management-inspection

While a move-out inspection is not strictly required by statute, many landlords conduct one to ensure transparency and reduce disputes. Documenting the condition at move-out helps support any deductions made from the deposit.

Security Deposit Refund in Washington

Under Washington law, landlords are required to return a tenant’s security deposit within 30 days after the tenant vacates the rental unit or after the landlord becomes aware that the tenant has abandoned the property.

If the landlord makes any deductions from the deposit, they must provide the tenant with a written, itemized statement that clearly explains each deduction and the amount withheld. This statement must be sent along with any remaining portion of the deposit within the same 30-day timeframe.

Failure to comply with the 30-day deadline or to provide proper documentation may result in the landlord being required to return the entire deposit. In some cases, tenant may recover the deposit and the court may award damages, costs, and attorneys’ fees depending on the circumstances. LINK

Change in Property Ownership

When a rental property changes ownership, Washington law provides two options for handling the tenant’s security deposit. The outgoing landlord may return the deposit directly to the tenant, minus any lawful deductions, and notify the new owner that the deposit has been returned.

Alternatively, the outgoing landlord may transfer the deposit to the new owner. In this case, the tenant must receive written notice identifying the new owner’s name, address, and confirmation that the deposit has been transferred.

The new owner then becomes responsible for complying with all Washington security deposit laws moving forward.

Bottom Line

Washington’s security deposit laws are detailed and strictly enforced. From requiring written agreements and move-in checklists to mandating trust accounts and a firm 30-day return deadline, landlords must follow each step carefully to remain compliant. Even small mistakes can result in forfeited deposits or legal liability.

If you have specific questions about Washington security deposit laws, it may be wise to consult a qualified Washington attorney. Alternatively, working with a knowledgeable property management company can help ensure deposits are handled correctly, disputes are minimized, and your rental business stays protected.
