Key Takeaways
- Washington security deposit law gives landlords flexibility in how they handle security deposits, but strict rules apply to how deposits are collected, stored, and returned.
- Some local jurisdictions, such as Seattle, impose their own additional limits and tenant protections that differ from Washington security deposit law.
- Working with an experienced property management company like Keyrenter West Seattle helps ensure compliance and protects both landlords and residents.
One of the key legal responsibilities landlords have under Washington’s landlord-tenant act is following the Washington state security deposit laws. These regulations apply to all landlords who require security deposits as part of the initial move-in costs. They establish essential requirements regarding written receipts, reasons for deductions, and timelines for returning funds.
As a landlord, it’s vital to follow these rules closely to remain legally compliant and avoid penalties. The following guide from Keyrenter West Seattle outlines the basics of Washington’s security deposit law and how to stay on the right side of it.
Maximum Security Deposit Law
Unlike some other states, Washington’s landlord-tenant act does not cap the maximum security deposit amount a landlord can charge as the tenant’s security deposit. You may set the amount freely, though most Washington landlords choose to limit it to about one and a half times the monthly rent. Charging more than that can make your rental unit less appealing and increase the time it takes to fill vacancies.
However, keep in mind that local governments can impose additional restrictions. For example, the City of Seattle limits the entire security deposit to one month’s rent. Always check your city’s ordinances to confirm you comply.
Landlords under Washington security deposit law also have the option to collect a non-refundable fee instead of a refundable security deposit. While a fee may offer flexibility, it must be clearly designated as non-refundable in the lease or written rental agreement to avoid disputes later.
Non-Refundable Fees
Landlords may collect non-refundable fees in addition to the tenant’s security deposit, including certain cleaning or administrative costs. To avoid deposit disputes, make sure the lease agreement clearly identifies each non-refundable fee in writing and follows applicable landlord-tenant laws.
If a fee is not properly designated as non-refundable, it may be treated as part of the refundable security deposit under Washington law, which can affect the deposit refund process. A clear written checklist and detailed rental agreement can also help document move-in charges and reduce misunderstandings if a landlord violates the applicable requirements.
Additional Pet Deposits and Fees
Landlords may charge additional pet deposits or pet fees to cover potential damage caused by animals. Some Washington landlords also charge monthly “pet rent,” depending on the terms outlined in the rental agreement.
When a tenant moves out, landlords should distinguish between actual pet-related damage and normal wear and tear to help prevent deposit disputes and support any deductions from the security deposit. Keeping the rental property clean and documenting its condition can also provide useful records for both the landlord and prospective landlord when evaluating property conditions.
However, local rules may limit how much you can charge. For example, in Seattle, a pet deposit cannot exceed 25% of one month’s rent. Always verify your local ordinances before collecting additional payments.
It’s important to remember that assistance animals are not considered pets under the Federal Fair Housing Act (FHA) or the Americans with Disabilities Act (ADA). You cannot charge a pet deposit or fee for a tenant with a verified assistance animal, as these animals are protected by federal and Washington state law.
Upfront Rent and Instalment Payments
Washington landlord-tenant law does not restrict how much money landlords can collect upfront for rent payments, security deposits, or fees, although certain situations may require installment payments. Landlords should clearly outline these charges and payment terms in the rental agreement.
If the combined upfront payment, including the security deposit, fees, and last month’s rent, exceeds 25% of the first month’s rent, the tenant may have the right to pay the amount over three consecutive monthly installments, as long as the rental period lasts at least three months.
Clearly documenting these terms can also help landlords address potential issues involving unpaid rent and other payment obligations. This rule helps make housing more accessible while establishing clear expectations for Washington landlords and tenants.
Move-In Condition Report
Before accepting a security deposit, Washington landlords are required to provide a written checklist for the move-in condition report. This report should detail the condition of the rental unit at the start of the tenancy and be signed by both the landlord and tenant, creating a useful record for distinguishing property damage from normal wear and tear.
If a landlord fails to provide the required report, there can be serious consequences, including potential liability for the full security deposit, along with court and attorney fees in qualifying circumstances. Maintaining a detailed, signed record can help protect both parties if a dispute arises later, including disagreements related to rent payments or a tenant’s obligation to pay rent.

Holding Security Deposits
Washington landlords must store tenants’ security deposits in specific, secure ways. Washington landlord-tenant law allows deposits to be held in any of the following:
-
A licensed escrow account.
-
A state or federal savings bank, credit union, or savings and loan association.
-
A state or national bank and trust company.
Deposits must be kept separate from your personal or business funds. Mixing tenant security deposits with your own money is prohibited, and a landlord fails to follow these requirements could face a dispute that may ultimately be addressed through small claims court or another legal process. Depending on the circumstances, a landlord may also face claims involving the full security deposit.
Additionally, you must provide the tenant with the name and address of the financial institution where the security deposit is held. This requirement applies to the security deposit and should not be confused with other move-in funds, such as last month’s rent. Clear records of where each type of payment is held can help promote transparency and reduce disputes.
If You Sell the Rental Property
When a rental property is sold, the Washington landlord must transfer the security deposits to the new owner or to an equivalent account. The outgoing landlord must then notify the tenants in writing of the new account’s name and address.
This ensures that tenants know where their funds are held and who is responsible for returning the security deposit at the end of their tenancy.
Allowable Security Deposit Deductions
Landlords can make deductions from tenants’ security deposits only for specific, legitimate expenses stated in the lease or written rental agreement. Common allowable deductions include:
-
Unpaid rent or utilities.
-
Costs to repair damages beyond normal wear and tear.
-
Failure to return keys or access devices, especially in the case of eviction.
-
Excessive cleaning costs.
-
Trash or debris removal.
These deductions should be clearly distinguished from other move-in funds, such as last month’s rent, which may be subject to different rules and should be addressed separately in the rental agreement. A detailed written checklist documenting the property’s condition at move-in can also help landlords determine whether claimed damage goes beyond normal wear and tear.
There is no statutory limit on the amount of deductions, but they must be reasonable, legally permitted, and well-documented. Landlords should keep written receipts, invoices, or photos as proof of the actual costs incurred.
Returning the Security Deposit
After a tenant moves out, landlords must return the remaining balance of the security deposit within 30 days. This timing should be noted in the written lease. If you make any deductions, you must also provide a written statement itemizing those deductions within the same timeframe.
Failing to return the security deposit or provide an explanation within 30 days can expose you to legal penalties and may require you to pay the tenant’s court and attorney fees. Prompt, transparent communication helps maintain professionalism and avoid disputes.

Frequently Asked Questions About Washington Security Deposit Laws
What Should Landlords Do with Security Deposits During A Property Sale?
When a rental property changes ownership, the security deposit should be handled as part of the transition rather than treated as ordinary sale proceeds. Washington law requires deposits held in trust to transfer to the successor landlord’s equivalent trust account when the landlord’s status changes, with prompt written notice to the owner and tenant about the new depository information.
Are Nonrefundable Fees Treated the Same as Security Deposits in Washington?
Not necessarily, and the distinction should be clear in the rental agreement. Washington law says a nonrefundable fee cannot be designated as a security deposit, and the written rental agreement must clearly identify the fee as nonrefundable. If the agreement does not make that designation, the fee may be treated as a refundable deposit and become subject to the applicable deposit rules.
What is the Best Way to Manage the 30-Day Security Deposit Deadline?
Treat the 30 days as a firm internal deadline rather than waiting until the end of the period to begin the move-out accounting process. Once possession is returned, organize the inspection records, determine whether deductions are supported by the lease and applicable law, gather invoices or estimates, and prepare the required statement and refund.
Do Seattle Landlords Have Different Security Deposit Requirements?
Yes, Seattle rental properties can be subject to municipal requirements in addition to Washington state law. For example, Seattle currently limits security deposits and certain move-in fees together to one month’s rent, while allowing a separate pet deposit of up to 25% of one month’s rent under its rules. Seattle also has specific installment-payment requirements for qualifying move-in costs.
Can A Property Management Company Help with Security Deposit Compliance?
A property management company can help owners build consistent processes around leasing, move-in documentation, property inspections, maintenance, financial reporting, and move-out accounting.
