Seattle Security Deposit & Move-In Fee Rules (2026)
What you may collect at move-in, what has to be refundable, when the deposit has to be back, and what it costs to get the deadline wrong.
Reviewed August 2026 • Seattle, Washington
Securing a deposit for your rental property helps protect against specific cases of a tenant's lease violation. A deposit can be used to cover damage done to the property, cleaning it back to the condition it was in prior to rental, replacing keys, or covering back rent owed. Though often collected together, the deposit is separate from any non-refundable move-in fee and from advance rent such as the last month — and in Seattle there are a number of rules to keep in mind for each.
What you can collect at move-in
Seattle caps the combined total of the security deposit and any non-refundable move-in fees at one month's rent. A pet damage deposit is limited separately to 25% of the monthly rent.
Where a tenant asks in writing, you must allow the deposit, any non-refundable fees and the last month's rent to be paid in installments rather than in a single sum. The obligation is conditional — it applies where the total of deposits and non-refundable fees does not exceed 25% of the first full month's rent and you are not requiring last month's rent up front — so read the ordinance against your own fee schedule rather than assuming either way.
Document the condition, or you cannot charge for it
Washington requires a written checklist or statement describing the condition of the unit, signed by both parties, before a deposit may be collected at all. Having the tenant complete that walk-through at move-in gives you a record of the property's condition at the time it was rented, and it is the document every later deduction is measured against.
The tenant is not responsible for damage that is considered normal wear and tear — deterioration attributable to ordinary use. The damages a tenant can be billed for are generally those that were avoidable, or caused by negligence or misuse. A tenant is not responsible for an air handler failing; they are responsible for structural damage to the ceiling caused by never reporting the leak.
When a tenant moves out
The deposit must be returned, or a complete itemized statement of deductions provided, within 30 days of the tenant vacating and returning possession. The same clock runs from the day you learn the unit was abandoned.
Getting this wrong is expensive in a way that surprises people. A landlord who wrongfully withholds any part of a deposit is liable for the full amount withheld, up to twice the deposit in damages, and the tenant's reasonable attorney's fees. The deadline, not the merits of the deduction, is what most disputes turn on.
What the lease should say
The lease for your rental should include details about the deposit and the terms for its return, including but not limited to:
- That the tenant is responsible for the full lease term, with any early-termination terms documented
- That all rent and fees, including utilities, are paid in full
- That keys and any other items provided are returned
- That the tenant's belongings are removed entirely and the property is cleaned to its condition at move-in
- Where the deposit is held, which Washington requires you to disclose
For covered expenses — those outside normal wear and tear, and outside conditions that existed before the tenancy — a deposit collected and returned correctly protects against exactly the unexpected cost it was designed for.
Frequently asked questions
How much can a Seattle landlord charge for a security deposit? +
Seattle caps the security deposit plus any non-refundable move-in fees at one month's rent combined. A pet damage deposit is capped separately at 25% of the monthly rent. Washington also requires a signed written condition checklist before any deposit may be collected.
How long does a landlord have to return a deposit in Washington? +
Thirty days from the day the tenant vacates and returns possession, or from the day the landlord learns the unit was abandoned. Within that window you must either refund the deposit in full or provide a complete itemized statement of the deductions taken.
What is the penalty for returning a deposit late in Washington? +
A landlord who wrongfully withholds any portion of a deposit is liable under RCW 59.18.280 for the full amount withheld, up to twice the amount of the deposit in additional damages, and the tenant's reasonable attorney's fees. Missing the 30-day deadline is the most common way landlords end up there.
Can a Seattle tenant pay the deposit in installments? +
Yes, on written request, where the conditions in the ordinance are met — broadly, where the total of deposits and non-refundable fees does not exceed 25% of the first full month's rent and last month's rent is not required up front. Check the ordinance against your own fee schedule before refusing a request.
