How to Write a Security Deposit Demand Letter

Use your full legal name and current address

The letter is a legal document. Include your full name as it appears on the lease, your current mailing address (for the landlord to respond), and the rental property address the deposit covers.

State the deposit amount and move-out date

Be specific: the exact dollar amount you paid and the date you surrendered the unit. These two facts anchor the statutory timeline in most states.

Reference your state's return deadline and statute

Citing the specific statute (e.g., "California Civil Code § 1950.5" or "Texas Property Code § 92.103") signals that you know the law and are tracking the timeline. This alone increases response rates.

Describe the issue clearly

Whether the deadline passed with no response, the refund was short, or deductions seem unsupported — state the facts without emotional language. "I have not received my deposit or an itemized statement as of [date]" is stronger than "you stole my money."

Set a clear response deadline

Give the landlord a reasonable but firm window to respond — typically 7 to 14 days. This shows you are serious and creates a documented escalation point if they don't reply.

State your next steps if they don't respond

Mention that you may pursue remedies available under your state's statute, such as small claims court or statutory damages. Keep it factual, not threatening.

Print, sign, date, and send properly

A signed, dated physical letter carries more weight than an email alone. Send by certified mail with tracking for proof of delivery, and keep a copy for your records. You can also email a scanned PDF with a clear subject line.
