Washington Security Deposit Law, in Plain English

Washington ties the security deposit to documentation more tightly than any other state: no signed condition checklist means no lawful deposit — and at move-out, nothing can be deducted for items the checklist didn't reasonably document. Here's how RCW 59.18.260 through .280 actually work, for both sides of the lease.

1 signed checklistRequired before any deposit can be collected — describing premises, fixtures, equipment, appliances, and furnishings (RCW 59.18.260)
30 daysDeadline to deliver the retention statement, supporting documentation, and refund (replaced the old 21 days in July 2023)
$0What can be deducted for ordinary-use wear, undocumented items, or whole-item replacement of partial damage
Up to 2x + feesCourt's discretion for intentional refusal — and the prevailing party recovers attorney's fees either way

No checklist, no deposit — literally

Most states treat move-in documentation as a good idea. Washington makes it a legal gate: under RCW 59.18.260, a landlord may not collect any deposit unless the rental agreement is in writing and the tenant receives a written checklist or statement describing the condition and cleanliness of the premises — including fixtures, equipment, appliances, and furnishings. Both parties sign and date it; the tenant keeps a copy.

Skip the checklist and collect a deposit anyway, and the statute's answer is blunt: the landlord is liable to the tenant for the full deposit, and the prevailing party in any suit recovers costs and reasonable attorney's fees.

The deposit itself has rules too: RCW 59.18.270 requires it to sit in a trust account at a Washington financial institution or with a licensed escrow agent, with a written receipt to the tenant naming the depository. There's no statewide cap on the amount — though nonrefundable charges must be labeled as fees, not deposits, and some cities add local limits under municipal law.

What your move-in checklist says is what you can later deduct

The 2023 amendments (effective July 23, 2023) turned the checklist from a formality into the outer boundary of the landlord's move-out claims. RCW 59.18.280 now prohibits withholding any portion of a deposit:

For wear resulting from ordinary use — the statute's replacement for "normal wear and tear," defined in RCW 59.18.030 as deterioration from the intended use of the unit, including breakage or malfunction due to age. Faded paint and traffic-worn carpet are categorically non-deductible.
For carpet cleaning — unless the landlord documents wear to the carpet beyond ordinary use.
For repairing or replacing fixtures, equipment, appliances, or furnishings whose condition was not reasonably documented in the move-in checklist. An undocumented item is an undeductible item.
Beyond the damaged portion — damage to part of an item supports charging for that part, not replacing the whole.

And for tenancies beginning on or after July 23, 2023, the 30-day retention statement must arrive with copies of estimates, invoices, or receipts for each deduction. A bare list of charges no longer satisfies the law.

The phrase doing the heaviest lifting in that statute is "reasonably documented." The legislature didn't define how thorough a checklist must be — it made thoroughness the landlord's problem. A checkbox form that says "kitchen: good" documents almost nothing; a room-by-room record with dated photos and video of every appliance and fixture documents everything. Between those two, Washington law now draws the line between deductions that survive and deductions that don't.

For tenants, the same statute is a shield: your signed copy of the checklist — required by law to be in your hands — plus your own dated record from day one is what makes "that was already broken" a documented fact instead of a claim.

A checklist that "reasonably documents" everything, in about 10 minutes.

After move-out: 30 days, a specific statement, and proof

The landlord has 30 days from termination and vacation to deliver three things: a full and specific statement of the basis for any amount retained, the supporting documentation (estimates, invoices, or receipts for post-July-2023 tenancies), and the refund. Note the deadline changed in 2023 — sources still citing 21 days are describing superseded law.

Miss the deadline, and the consequences stack: the landlord is liable for the full deposit and is barred from asserting any claim or defense for retaining any of it — the damage argument is simply gone. For intentional refusal, the court may add up to twice the deposit. And in any action over the deposit, the prevailing party recovers costs and reasonable attorney's fees, which means a landlord who guesses wrong pays the tenant's lawyer too.

Balance for landlords: the deposit is not a ceiling on real damage. A landlord can sue for amounts exceeding the deposit (with attorney's fees), though for post-July-2023 tenancies the suit must be filed within three years. And the checklist/documentation rules govern damage-based withholding — withholding for unpaid rent is handled separately.

When it goes wrong

Deposit disputes go to the small claims department of the district court — informal by design, generally no attorneys at the hearing without the judge's permission. What each side should bring: the rental agreement, the signed move-in checklist, the retention statement and its receipts (or proof none arrived within 30 days), all correspondence, and any dated room-by-room record of condition at move-in and move-out.

The attorney's-fee provision changes the math compared to most states: because the prevailing party recovers fees, weak withholding claims are more expensive to defend than to abandon — and well-documented ones are more expensive to challenge.

Preguntas frecuentes

How long does a landlord have to return a security deposit in Washington?

30 days after the tenancy ends and the tenant vacates. Within that window the landlord must deliver a full and specific statement of any amount retained, documentation supporting the deductions, and the refund. The old 21-day deadline was replaced on July 23, 2023 — if a source says 21 days, it's out of date.

Can a landlord collect a deposit without a move-in checklist in Washington?

No. RCW 59.18.260 makes a written, signed condition checklist a precondition to collecting any deposit at all. The checklist must describe the condition and cleanliness of the premises, fixtures, equipment, appliances, and furnishings; both landlord and tenant sign and date it, and the tenant gets a copy. A landlord who takes a deposit without one is liable for the full deposit, plus the tenant's costs and attorney's fees.

What can a landlord deduct from a deposit in Washington?

Damage beyond wear resulting from ordinary use, and unpaid rent or other amounts owed — with hard limits added in 2023. A landlord cannot withhold anything for ordinary-use wear, cannot charge for carpet cleaning without documenting wear beyond ordinary use, cannot deduct for repairing or replacing items whose condition wasn't reasonably documented on the move-in checklist, and cannot charge more than the cost of fixing the damaged portion when the whole item isn't ruined.

Does my Washington landlord have to prove deductions with receipts?

For tenancies that began on or after July 23, 2023, yes — the retention statement must come with copies of estimates, invoices, or receipts supporting each deduction. A bare list of charges no longer satisfies the statute.

What happens if the landlord misses the 30-day deadline?

The landlord becomes liable for the full deposit and is barred from asserting any claim to keep any of it. If the refusal was intentional, the court may award up to twice the deposit. In any suit over the deposit, the prevailing party also recovers costs and reasonable attorney's fees — which raises the stakes of guessing wrong for both sides.

Is there a limit on security deposit amounts in Washington?

No statewide cap. However, nonrefundable fees must be clearly labeled as fees rather than deposits, and some cities layer on local rules — Seattle, for example, restricts deposit amounts and allows installment payments under municipal law. Check your city's code.

Where does my landlord have to keep my deposit?

In a trust account at a Washington financial institution or with a licensed escrow agent, and you're entitled to a written receipt naming the depository. No interest is owed on the deposit, but failing to provide the receipt is its own compliance violation.

Can my landlord charge me for repainting or new carpet after I move out?

Only for damage beyond wear resulting from ordinary use — and only in proportion. Faded paint and traffic-worn carpet are ordinary use and can't be charged at all. Carpet cleaning requires documented wear beyond ordinary use. And if you damaged one section of a carpet or wall, the landlord can charge to fix that portion, not to replace the whole thing.

In Washington, the undocumented item is the undeductible item.
