Washington Security Deposit Demand Letter
You moved out, you left the place in decent shape, and your deposit still has not come back. In Washington, that is not a judgment call: under Revised Code of Washington section 59.18.280, your former landlord generally has 30 days to return your deposit or send an itemized statement of deductions. This generator produces a demand letter that cites RCW 59.18.280 by name, states the legal deadline, and puts your landlord on notice that small claims court — where Washington hears claims up to $10,000 — is the next stop. You do not need perfect English or a lawyer for this; the statute does the arguing. Fill in the blanks below, send it by certified mail, and keep a copy — the letter that cites the actual law is the one that gets answered.

[Your former landlord's name]
Re: Demand for return of security deposit — [Rental property address]
Dear [Your former landlord's name],
I am writing to formally demand the return of my security deposit of [Deposit amount] for the property at [Rental property address], which I have vacated and returned to your possession.
Under Revised Code of Washington section 59.18.280 (RCW 59.18.280), you were required to return my security deposit, or provide a written itemized statement of any lawful deductions, within 30 days. A full and specific written statement of the basis for any retention is required, and it must include copies of estimates received or invoices paid substantiating each damage charge — plus a statement of time spent and the reasonable hourly rate if the landlord did the repairs personally. Deductions for normal wear and tear are not permitted.
As of the date of this letter, I have received neither my deposit nor a lawful accounting for it. Please send the full amount of [Deposit amount] to my forwarding address: [Forwarding address for payment].
If I do not receive payment or a lawful written response within 10 days, I will file a claim in small claims court, where Washington law allows claims up to $10,000, and I will pursue every remedy available under RCW 59.18.280, including any statutory damages for wrongful retention.
I would prefer to resolve this without litigation. Prompt payment will close the matter.
Sincerely,
[Your full name]

Security deposit law in Washington
- Return deadline
- 30 days
- Governing statute
- RCW 59.18.280
- When the clock starts
- The full statement of any withholding, supporting documentation, and any refund are due within 30 days after the rental agreement terminates and the tenant vacates (or within 30 days after the landlord learns of an abandonment). The deadline was lengthened from 21 to 30 days effective July 23, 2023, in exchange for much stricter documentation duties.
- Itemized deductions
- A full and specific written statement of the basis for any retention is required, and it must include copies of estimates received or invoices paid substantiating each damage charge — plus a statement of time spent and the reasonable hourly rate if the landlord did the repairs personally.
- If it's wrongfully kept
- A landlord who misses the deadline is liable for the full deposit and is barred from asserting any claim to keep any of it; the court may award up to two times the deposit for an intentional refusal, and the prevailing party recovers costs and reasonable attorney fees.
- Small claims limit
- $10,000 for individuals (small claims division of district court, RCW 12.40.010)
Worth knowing: No deposit can be collected at all unless there is a written rental agreement and a signed move-in checklist — and the landlord cannot charge for damage to any item whose condition wasn't documented on that checklist. Carpet cleaning can only be deducted with documentation of wear beyond ordinary use. Undocumented damage claims cannot be sent to collections or reported to tenant-screening services, and damage lawsuits must be filed within three years for newer tenancies. Seattle adds its own local caps on deposits and fees.

Field notes
Three tips before you send
- Send it by certified mail with a return receipt — that dated record is the first exhibit a Washington small claims judge will ask about. Keep a copy with your move-out photos and lease.
- The full statement of any withholding, supporting documentation, and any refund are due within 30 days after the rental agreement terminates and the tenant vacates (or within 30 days after the landlord learns of an abandonment). The deadline was lengthened from 21 to 30 days effective July 23, 2023, in exchange for much stricter documentation duties.
- If the deadline has already passed, skip the text-message negotiation. Filing in small claims ($10,000 for individuals (small claims division of district court, RCW 12.40.010)) usually costs under $75, and most landlords pay between the summons and the hearing.
