Security Deposit Demand Letter — All 50 States

If your landlord hasn't returned your security deposit by your state's deadline, you have the legal right to send a formal demand letter — and in many states, to sue for double or triple the amount withheld if they don't comply.

This guide explains what a security deposit demand letter must include, how to send it, and what to do if your landlord ignores it. Select your state below for the exact deadline, statute citation, and a free letter template.

What Is a Security Deposit Demand Letter?

A security deposit demand letter is a formal written notice to your landlord demanding the return of your deposit. It typically includes:

• Your move-out date and forwarding address
• The amount of deposit paid and not returned
• Your state's security deposit statute (e.g., Cal. Civ. Code § 1950.5)
• The landlord's legal deadline to return the deposit
• A demand for payment within a specified timeframe (typically 14 days)
• Notice of intent to sue in small claims court if ignored

When to Send a Demand Letter

Send your demand letter the day after your landlord's return deadline passes. Do NOT wait longer — courts look favorably on tenants who act promptly. Most state statutes require the landlord to return the deposit within 14–60 days of move-out.

How to Send It

1. Write the letter citing your state's exact statute.
2. Send via USPS certified mail with return receipt requested — this creates undeniable proof of delivery.
3. Keep the receipt and green card — these are your evidence in court.
4. Give 14 days to respond. If no response, file in small claims court.

Penalties for Landlords Who Don't Comply

Most states impose significant financial penalties on landlords who wrongfully withhold deposits:

• 2× the deposit: Most states (CA, NY, MI, WA, etc.)
• 3× the deposit: MA, GA, TX, FL (with willful violations)
• Plus attorney's fees: Many states allow fee shifting in small claims
