Washington landlord kept your whole deposit and never sent a statement? The demand letter is short.

Of all the Washington security-deposit fact patterns, the cleanest one for a tenant is "the landlord kept the entire deposit and never sent the statement." RCW 59.18.280 says the landlord must mail a full and specific statement of the basis for retaining any portion of the deposit within 30 days of termination and vacancy. If that statement never went out, the landlord cannot retain any portion of the deposit, period. The merits of any charges the landlord might have raised in a statement are irrelevant because the statute conditions retention on having sent the statement in the first place. A demand letter on this fact pattern is essentially a one-page document with a date table and a citation, and it works because the landlord knows it.

The deadline arithmetic

The 30-day clock under RCW 59.18.280 starts when the rental agreement terminates and the tenant vacates the unit, whichever is later. The statement must be mailed within those 30 days to the tenant's last known address, which is the move-out address unless the tenant gave a forwarding address. "Mailed" is the operative act, not "received." A landlord who can prove the statement was put in the mail on day 28 has satisfied the rule even if the tenant received it on day 35. A landlord who cannot prove mailing within the window has not.

If the tenant abandoned the unit (left without notice and without paying rent), the landlord may have a longer window under RCW 59.18.310, with the 30-day clock running from when the landlord learns of the abandonment. This is the carve-out landlords reach for when the timeline is tight. The tenant's response is to document when the landlord actually knew the unit was vacant (key return, cancelled utilities, post-move-out walkthrough, notice from a property manager). A landlord who knew the unit was vacant on day one cannot claim abandonment to extend the clock to day 60.

What "no statement" actually looks like

There are four common variants of the no-statement fact pattern.

• Pure silence. The tenant moved out, returned keys, gave a forwarding address, and never heard back. The deposit was simply not returned and no statement arrived.
• Late statement. A statement did arrive but it was postmarked after the 30-day window. The late statement is functionally a no-statement case because the right to retain expired before the statement was mailed.
• Statement sent to the wrong address. The landlord mailed the statement to the move-out address even though the tenant provided a forwarding address. Whether that satisfies "last known address" depends on the form and timing of the forwarding-address notice. A written, dated forwarding-address notice the landlord acknowledged usually defeats the wrong-address defense.
• Verbal-only response. The landlord said something verbally about the deposit (kept for damages, kept for unpaid rent, will return next month) but never sent a written statement. Verbal communication does not satisfy the statutory requirement that the statement be in writing and mailed.

What the demand letter should do

• States the move-out date, the date keys were returned, and the date the forwarding address was given. These dates control the 30-day clock.
• States that no statement was received (or that the statement was untimely, sent to the wrong address, or verbal only).
• Cites RCW 59.18.280 for the operative consequence: the landlord cannot retain any portion of the deposit.
• Demands return of the deposit in full.
• References the discretionary statutory enhancement up to two times the deposit for intentional refusal and the one-way fee-shifting under the same section.
• Sets a 14-day response window.
• Sends by USPS certified mail with return receipt, plus email where the landlord uses email.

Documents to upload before the letter goes out

• The lease, including any addenda.
• The deposit-payment record (cancelled check, bank statement, receipt).
• The move-out notice the tenant sent, with the date.
• The key return record (email, signed receipt, photo of mailed keys).
• The forwarding-address notice the tenant sent, with the date and method of delivery.
• Any messages with the landlord (text, email, voicemail transcript) about the deposit.
• A short timeline: tenancy start, lease end, move-out, key return, forwarding address, current status.

Sergei's practical note

This is the cleanest matter type in the Washington landlord-tenant catalog. When the file shows a clear move-out date, a returned key, a forwarding address, and silence past the 30-day window, the demand letter is short and the response rate is high. Where the matter gets more complicated is at the edges: a landlord who claims abandonment to extend the clock, a landlord who sent a statement but the tenant never received it, or a tenant who paid the deposit informally and cannot prove the amount. Those edge cases are where the $125 written email evaluation pays for itself, because the demand letter has to anticipate the landlord's response.

When this is the wrong tool

If the deposit was tiny (under $200), small claims is faster than a paid letter. If the tenant owes the landlord money that exceeds the deposit, the offset has to be addressed before the deposit claim makes sense. If the lease was commercial rather than residential, Chapter 59.18 RCW does not apply. And if the landlord did send a statement on time but the tenant disputes the charges, the case is a damage-claim dispute, not a no-statement case, and the framing is different.

What I review when you send the file

I read the lease, the move-out notice, the key-return record, the forwarding-address notice, and any messages with the landlord, and confirm that the 30-day window expired without a written statement. The $125 written email evaluation tells you whether the file supports a clean no-statement demand letter, whether a possible abandonment defense complicates the picture, or whether small claims is the more efficient path on a small deposit.
