Security Deposit Return in Washington: The Checklist Rule

Washington gives the landlord 30 days to return your deposit or explain in writing what they kept. But there is a prior question that decides most Washington deposit disputes before the deadline matters at all: did you sign a written move-in checklist?

If you did not, the landlord was not entitled to take a deposit in the first place. Under RCW 59.18.260 no deposit may be collected unless the rental agreement is in writing and the landlord gave you a written checklist describing the condition, cleanliness and existing damage of the place, signed and dated by both of you, with a copy to you. Collect a deposit without that, and the landlord is liable to you for the amount of the deposit — and cannot withhold anything for damage, however real the damage is.

Find the checklist before you argue about anything else

Go and look for it now. It is the document you probably signed in a hurry on the day you collected the keys, listing the state of the walls, the carpet, the appliances and the fixtures. It may be called a condition report or a move-in inspection.

If it exists and you signed it, it is still your best evidence: anything noted on it as already damaged cannot be charged to you later.

If it does not exist, say so first and in writing, before you get into whether the carpet was worn. The checklist requirement is not a formality the landlord can cure afterwards — it had to happen at the start of the tenancy.

Where your money is supposed to be

Under RCW 59.18.270 the deposit goes into a trust account at a bank or with a state-licensed escrow agent, and the landlord owes you a written receipt naming the institution. Washington does not require the account to pay you interest, and does not require the landlord to hand over any interest it does earn — one of the few places where Washington gives a tenant less than the north-eastern states do.

The 30 days have passed

1. Establish whether a signed move-in checklist exists. That single fact may decide the whole thing.
2. Send one written demand naming RCW 59.18.280, the date the 30 days expired, and the amount. If no checklist exists, name RCW 59.18.260 as well.
3. Note that the prevailing party recovers court costs and reasonable attorney fees, and that bad faith exposes the landlord to twice the deposit.
4. Small claims handles deposits and needs no lawyer. Washington’s own washingtonlawhelp.org has the forms and the procedure.

What can legitimately be deducted

Damage beyond ordinary wear and tear, and in Washington also unpaid rent, late charges, abandonment losses and attorney fees where the lease provides for them — a broader list than many states allow. That makes the checklist more important rather than less: it is the baseline against which “damage” is measured.

What your lease controls

The amount, since there is no statewide cap, unless you rented in a city that sets one — Seattle allows one month’s rent unfurnished and two furnished. What the lease cannot do is waive the checklist requirement, the trust-account duty or the 30 days.

When this needs a lawyer

Usually not, and the fee award means a landlord ignoring a clear demand is taking a risk. Get advice if the deductions run well past the deposit, if there is a disputed rent counterclaim, or if the landlord is relying on a checklist you do not remember signing. Washington’s legal aid network is unusually good on tenancy and costs nothing.
