Under 765 ILCS 710, your landlord had 30 days to itemize (45 days to refund if no itemization is given) to return your security deposit or itemize deductions. If they blew that deadline, Illinois law can make them owe up to 2× the amount they kept.
Illinois's security-deposit statute, 765 ILCS 710, gives your landlord 30 days to itemize (45 days to refund if no itemization is given) after your tenancy ends to either return your full deposit or send you an itemized list of lawful deductions. This is a hard deadline — not a suggestion.
If your landlord let that window pass without returning your money and without a proper written accounting, they have almost certainly violated the statute — and in most states that alone forfeits their right to keep a single dollar.
This is the leverage most renters don't know they have. Under Illinois law, a landlord who wrongfully withholds a deposit can be liable for twice the deposit for bad-faith noncompliance, plus court costs and attorney fees.
Answer a few questions and we'll generate a letter citing 765 ILCS 710, your exact deadline, and the penalty your landlord now faces — ready to sign and send.
Build my demand letter →Under 765 ILCS 710, your landlord generally has 30 days to itemize (45 days to refund if no itemization is given) after your tenancy ends to return your deposit or provide an itemized statement of any deductions. Missing that deadline usually forfeits their right to keep any of it.
Illinois law provides for twice the deposit for bad-faith noncompliance, plus court costs and attorney fees. For example, a landlord who kept a $1,500 deposit in bad faith could be on the hook for as much as $3,000. That exposure is exactly what makes a properly worded demand letter effective.
Usually no. A demand letter that cites 765 ILCS 710, the 30 days to itemize deadline, and the penalty your landlord faces resolves most disputes. If it doesn't, security-deposit cases are common and inexpensive in Illinois small claims court.
It should state the amount withheld, the date your tenancy ended, the specific statute (765 ILCS 710), the return deadline your landlord missed, and the statutory penalty they now risk — then demand payment by a firm date. DepositProtector builds this for you automatically.
