Home > Guides > Security deposit demand letter
State the rental address and tenancy dates, list the deposit amount and what you are owed, give a clear deadline to pay, and send it by tracked mail. Keep a copy of the letter and the delivery receipt for your records.
This is general information, not legal advice.
Send one when the return deadline in your state or province has passed, or when the landlord returned only part of the deposit without an itemized explanation you can accept. Most jurisdictions set a deadline for landlords to return a deposit or send an itemized list of deductions, often counted from the move-out date or from the date you gave a forwarding address. Check the rule where the rental sits before you write, since deadlines and penalties differ widely, and some places bar a landlord from keeping any deduction if the deadline is missed.
Do not wait too long. A demand letter sent promptly after the deadline shows you are serious, and it starts a paper trail while memories and records are fresh. If you already asked informally and got no reply, say so in the letter with the date of that request.
| Include in the letter | Detail to give | Why it matters |
|---|---|---|
| Rental address and unit | Full address, apartment number | Identifies the tenancy exactly |
| Tenancy dates | Move-in and move-out dates | Anchors the deadline clock |
| Deposit paid | Amount and date paid, if known | Sets the starting figure |
| Amount demanded | Full deposit or the unpaid balance | Leaves no doubt about the claim |
| Forwarding address | Where to send payment | Removes any excuse for delay |
| Deadline | A specific calendar date to pay by | Creates a clear next step |
Go through the itemized list line by line. Landlords can usually deduct for unpaid rent and for damage beyond normal wear and tear, but not for routine cleaning, repainting after a normal tenancy, or pre-existing damage noted on a move-in inspection. If a deduction looks wrong, challenge it in the letter with a specific reason: the damage was noted at move-in, the item was already old, or the charge has no receipt or invoice attached. Photos from move-in and move-out are your best support here, so gather them before you write.
Ask for receipts or invoices for any deduction you dispute. Some jurisdictions require landlords to back deductions with documentation, and a landlord who cannot produce it may have to drop the charge. Keep your tone factual even when a deduction feels unfair. A letter that reads like a calm audit is far more persuasive to a mediator or a small claims judge than one that reads like an argument.
Give a specific date, not a vague window. A common choice is two to four weeks from the date of the letter, or the period your local rules allow. State what happens if the deadline passes: that you will pursue the matter through the local tenancy board, small claims court, or mediation, as fits your area. Do not threaten anything you do not intend to do, and do not invent a penalty or a fine that the law does not provide. A deadline you will actually act on is stronger than a dramatic threat you will not follow through on.
Send the letter by tracked mail: certified mail in the United States, registered mail in Canada. The delivery record proves the landlord received the demand and starts the clock on your deadline in a way no one can dispute. Keep the receipt, a copy of the letter, your lease, move-in and move-out photos, and any prior messages about the deposit together in one file.
Your next step depends on the amount and your area. Many deposit disputes go to small claims court or a tenancy tribunal, where filing fees are modest and lawyers are often not required. Some areas offer free mediation first, which can settle the matter faster. Before filing, check whether your jurisdiction allows extra damages when a landlord wrongfully withholds a deposit, since some do, and that affects how you frame the claim. Bring your demand letter, the delivery proof, the lease, and your photos to any hearing, since that file is your case.
