Jordan Avery 88 New Haven Road, Riverton, Illinois August 29, 2026 Northgate Property Management 1200 Commerce Street, Suite 400, Riverton, Illinois SENT VIA USPS CERTIFIED MAIL RE: Demand for return of security deposit — 482 Maple Court, Apt 2B, Riverton, Illinois Dear Northgate Property Management: I was the tenant at 482 Maple Court, Apt 2B, Riverton, Illinois until June 20, 2026, on which date I surrendered the premises. I paid a security deposit of $1,500.00. To date, no portion of my deposit has been returned to me. I have received no itemized statement of deductions. The grounds given for withholding — alleged damage beyond normal wear and tear; cleaning charges — are disputed. Under 765 ILCS 710/1 (Security Deposit Return Act), a landlord in Illinois must return a tenant’s security deposit, or provide a written itemized statement of lawful deductions, with the itemized statement due within 30 days and the refund within 45 days of termination (properties of 5 or more units). That period expired on August 4, 2026. To the extent any statutory period runs from receipt of a tenant’s forwarding address, this letter provides that address, and the applicable period runs from your receipt of it. For the record: The unit was left clean, keys were returned on the move-out date, and two written follow-ups have gone unanswered. My records of this tenancy include date-stamped photographs of the condition of the premises; the lease agreement; written correspondence with you or your agents. I am prepared to present these records in court if necessary. Please be aware that under 765 ILCS 710/1 (Security Deposit Return Act), a landlord who wrongfully withholds a security deposit may be held liable for up to 2 times the amount wrongfully withheld, together with attorney's fees and costs. On my deposit of $1,500.00, that exposure may substantially exceed the deposit itself. This letter also serves as written notice of my forwarding address, stated above, for all purposes under 765 ILCS 710/1 (Security Deposit Return Act). Accordingly, I demand payment of $1,500.00 within fourteen (14) days of the date of this letter, delivered to my address above. If I do not receive payment, I intend to pursue every remedy available to me under 765 ILCS 710/1 (Security Deposit Return Act), including filing suit in small claims court, where I may seek the statutory damages described above, together with attorney's fees and costs where the statute allows. I would prefer to resolve this without court involvement, and prompt payment will end the matter. Sincerely, Jordan Avery
Why each part is there

The certified-mail line

Signals the delivery is being documented — the record a small-claims judge wants to see.

The statute citation

765 ILCS 710/1 (Security Deposit Return Act) tells the landlord you know exactly which law governs — and that its clock has already run out.

The penalty paragraph

Bad-faith violations can make the landlord liable for twice the deposit plus attorney's fees and costs. Stating it plainly is usually what moves a landlord to settle.

The forwarding-address clause

Several statutes start (or restart) their clock at receipt of a written forwarding address — the letter closes that loophole itself.

The evidence recital

Listing photos, the lease, and correspondence tells the landlord a court case is already assembled — without a threat ever being made.
