A security deposit demand letter is a formal notice you send to a former landlord or property manager to request the return of your deposit after you move out. It documents the rental address, lease dates, deposit amount, your move-out condition, and a clear deadline for payment or an itemized list of lawful deductions. Because it is written, dated, and delivered by a traceable method, it becomes evidence that you asked for your money in a reasonable way and gave the landlord a fair chance to respond.
Quick Facts
- Itemized deductions are typically required when any part of a deposit is withheld.
- Good records strengthen your position, including photos, the lease, receipts, and move-out communications.
- Use a delivery method you can prove, such as certified mail, a courier with tracking, or confirmed email.
How to Write a Security Deposit Demand Letter
A strong letter follows the order of the page from top to bottom and reads like a brief timeline of the tenancy. Keep your tone professional and factual. After you state what you want returned and by when, explain where to send the payment and how to reach you to confirm.
Add the date
Write the date you are sending the letter. Use a future-ready format with the month spelled out to avoid confusion.
Example
August 5, 2094.
List the recipient and mailing address
Address the person who manages deposit returns. Include the company name, street address, city, state, and ZIP code.
Example
John Stamos, Highline Property Management, 455 Lexington Avenue, Suite 900, New York, NY 10017.
Write a clear subject line
Use a concise “Re” line so your request is obvious when the envelope is opened. Include the rental address and the date the tenancy ended.
Example
Re: Security Deposit Return for 221 West 16th Street, Apt 4A, New York, NY 10011; Tenancy Ended July 31, 2094.
Use a professional salutation
If you know the recipient’s name, use it. If not, write “Dear Property Manager.”
Example
Dear Mr. Stamos,
State the lease timeline and deposit facts
Open with a short paragraph that identifies the unit, the lease dates, the deposit you paid, when you returned the keys, and that you left the place in good condition aside from ordinary wear. This frames the entire request in facts.
Example
I rented 221 West 16th Street, Apt 4A, New York, NY 10011 from September 1, 2093 to July 31, 2094. I paid a security deposit of $2,400.00 on August 15, 2093, returned the keys on July 31, 2094, and left the premises in good condition aside from ordinary wear.
Make the demand and set a deadline
Ask for the full amount and set a specific response date for either payment or a proper itemization with receipts. A firm but reasonable deadline shows you are organized and serious.
Example
Please return the full deposit of $2,400.00 to the forwarding address below. If you claim any deductions, send an itemized statement with supporting receipts as required by state law. I request payment or the itemization by August 19, 2094.
Give payment and contact details
Provide a reliable forwarding address and a way to coordinate electronic payment.
Example
Send payment to 860 Washington St, New York, NY 10998. For electronic payment, contact me at [email protected] or (212) 555-0174.
State next steps if there is no response
Explain what you will do if the deadline passes. This is not a threat; it is notice that you will use available remedies.
Example
If I do not receive the deposit or a proper itemization by the date above, I will consider next steps, including filing in small claims court.
Close and sign
End with a courteous sign-off and your printed name. A handwritten signature on a mailed copy underscores authenticity.
Example
Sincerely,
Sheryl Lee
Keep a complete record
Save a copy of the signed letter, your proof of mailing or email read receipt, your photos, and the lease. This package becomes your evidence if you need to escalate.

When to Send and Timing
Send the letter soon after move-out once you return keys and give a forwarding address. A prompt letter shows diligence and gives the landlord a fair window to respond. Review your lease for any stated time frames and check your state’s rules on deposit return and itemization so your deadline is reasonable.
Evidence and Enclosures to Consider
Include copies that support your request. Common documents include the signed lease, your deposit receipt, a move-in checklist, move-out photos with dates, emails about repairs, and a copy of your new-address notice. Keep originals for yourself.
Delivery and Proof of Notice
Use a method you can verify. Certified mail with return receipt, a courier with tracking, or email that shows delivery and read confirmation can all create a record. Save the tracking page or the email confirmation with your copy of the letter.
If the Landlord Claims Damages
You can respond in writing and ask for receipts, invoices, or estimates that match the deductions and the dates. Distinguish ordinary wear from actual damage, reference your photos, and invite a reasonable conversation about disputed amounts. If the landlord provides a partial refund, you can accept the undisputed portion while continuing to dispute the rest in writing.
Common Mistakes to Avoid
Avoid vague subject lines, missing dates, and open-ended requests. Do not overstate legal penalties. Do not include accusations or emotional language. Keep it short, factual, and easy to process, then let your documentation do the heavy lifting.
FAQs
Choose a date that is soon enough to keep things moving and long enough for mailing and review. Two weeks is a common window in practice, but confirm what your lease and state rules say. Your deadline should match a trackable delivery so you know when the clock starts.
Certified mail is a reliable way to prove what you sent and when it arrived. A courier with tracking or a confirmed email can work if your state accepts electronic notice or your lease permits it. Whatever method you choose, save the letter, attachments, and the delivery proof together.
Ordinary wear is the gradual change from normal use, such as minor carpet wear or light nail holes. You can dispute deductions for ordinary wear by pointing to dated move-out photos, the signed lease, and any checklists. Ask for receipts or invoices that show actual repair or cleaning beyond ordinary wear.
Some states require interest on deposits or set penalties for wrongful withholding. Because rules differ, avoid quoting numbers in your first letter. If the deposit is not returned after your deadline, read your state rules or speak with a local housing advisor before your follow-up.
Write back quickly. Thank the landlord for the partial refund, dispute specific line items with references to your photos or lease, and ask for receipts that match the dates and amounts. State a short follow-up deadline and keep your proof of delivery.
