Illinois landlords have 30 days to return your deposit — but only 14 days to send the itemized deduction statement. Miss either deadline and they may owe you double the deposit plus attorney fees.
Check My Illinois Case →Illinois has two separate frameworks: the statewide Security Deposit Return Act (765 ILCS 710) and the Chicago RLTO for city renters. Both are strong, but Chicago's is stricter in several ways.
765 ILCS 710 — Security Deposit Return Act ↗State law — the two-deadline system: Under 765 ILCS 710, if a landlord intends to make any deductions, they must send the tenant an itemized statement within 14 days of vacating. The remaining balance (if any) must accompany the statement. If returning the deposit in full with no deductions, the full return must happen within 30 days of vacating.
The critical 14-day rule: The 14-day clock is the tighter of the two deadlines and is the one landlords most commonly miss. If the landlord sends you an itemized statement on day 20, they have violated the statute — even if the deductions themselves might otherwise be valid. Missing the 14-day window for an itemized statement generally means the landlord must return the full deposit.
Double damages (765 ILCS 710 §1): If the landlord fails to return the deposit or provide the required itemized statement within the legal deadlines, they are liable for twice the amount wrongfully withheld, plus court costs and reasonable attorney fees.
Normal wear and tear in Illinois: Illinois courts have consistently defined normal wear and tear as ordinary deterioration from reasonable use — minor scuffs, small nail holes, slight carpet wear, fading. The landlord bears the burden of proving that any claimed damage is beyond normal wear.
Interest on deposits (Chicago only): The Chicago RLTO requires landlords to hold security deposits in a federally insured interest-bearing account and to pay tenants interest annually. The interest rate is set by the City Comptroller each year. Failure to pay interest is itself a violation that entitles the tenant to an amount equal to the interest plus court costs.
Written receipt required (Chicago): Chicago landlords must provide a written receipt for your security deposit within 2 business days, including the financial institution's name and address, and the account number (last 4 digits). Failure to provide this receipt can be grounds for returning the deposit without deductions.
Summary of RLTO §5-12-080 penalties: If a Chicago landlord (1) fails to pay interest, (2) fails to provide the required receipt, (3) fails to return the deposit or give a written statement within 30 days, or (4) wrongfully withholds any amount, the tenant is entitled to two times the security deposit plus interest, court costs, and attorney fees.
Note on Chicago RLTO exemptions: The RLTO does not apply to owner-occupied buildings with 6 or fewer units, certain religious organization properties, or certain other limited situations. If you're unsure whether the RLTO applies to your unit, contact the Metropolitan Tenants Organization.
If your rental was in Chicago, the RLTO applies (unless you were in an exempted property type). Chicago has the stronger protections, including the interest requirement. If you rented outside Chicago — Springfield, Rockford, Peoria, suburban Cook County, etc. — state law (765 ILCS 710) applies.
If it has been more than 14 days since you vacated and you have not received a written itemized statement of any deductions — not even a partial one — the landlord has very likely violated state law and must return the full deposit. Document the date you moved out and when (if ever) you received any written communication about deductions.
Cite 765 ILCS 710 (or Chicago Municipal Code §5-12-080 for Chicago tenants). Reference your move-out date, the deposit amount, and the missed 14-day or 30-day deadline. Demand return of the full deposit plus double damages within 14 days. Keep your certified mail receipt.
Court: Circuit Court of your county, Small Claims Division. Limit: $10,000 (under the Illinois Simplified Procedure limit). Filing fee: $50–$150 depending on county and claim amount. In Cook County, file at the Daley Center or your district courthouse. Find your courthouse at illinoiscourts.gov. Hearings typically scheduled 4–8 weeks out.
Both state law and the Chicago RLTO allow recovery of attorney fees. If you hire an attorney, include this in your claim. Even if you're self-represented, ask for your documented court costs and filing fees in your damages request.

Q: My landlord sent an itemized statement on day 17, not day 14. Does missing the 14-day window matter that much?
A: Yes — courts have been strict about Illinois's 14-day window. Missing it, even by a few days, means the landlord violated the statute and must return the full deposit. Keep the postmarked envelope from any statement you received. The date on the postmark (not the date of the letter, not the date you received it) determines compliance. A statement dated day 12 but mailed on day 16 is late.
Q: I rented outside Chicago. Does the Chicago RLTO interest rule still apply to me?
A: No. The Chicago RLTO applies only within the city limits of Chicago. Tenants in Evanston, Oak Park, Naperville, Springfield, Rockford, and everywhere else in Illinois are covered only by the state Security Deposit Return Act (765 ILCS 710), which does not require interest payments on deposits. The state law still provides the 14-day itemization deadline and double damages for violations.
Q: My landlord says the deposit is being withheld because I broke the lease early. Is that allowed?
A: A landlord can deduct unpaid rent (including any lease-break penalties specified in the lease) from the deposit, but the deduction must still be itemized in a written statement within 14 days. Simply announcing that the deposit is being held for "lease break" without a specific itemized statement within the required window violates the statute. Additionally, under Illinois law, landlords have a duty to mitigate by attempting to re-rent the unit — they cannot charge you for the full remaining lease term if they found a new tenant two months later.
Q: My Chicago landlord never paid me deposit interest for three years. How much do I owe?
A: The City Comptroller sets the interest rate annually. For multi-year tenancies, you can calculate the annual interest owed for each year and total it. If the landlord never paid and is now withholding your deposit, include the unpaid interest in your demand letter and court filing. The Metropolitan Tenants Organization (MTO) can help you calculate the amount owed based on your specific move-in date and deposit amount.
Q: My landlord is a property management company, not an individual. Does the law still apply?
A: Yes. The Illinois Security Deposit Return Act and the Chicago RLTO apply to all residential landlords, including property management companies managing buildings on behalf of owners. You can name both the property management company and the building owner in your small claims filing if you're uncertain which entity holds the deposit.
Essential documents: Signed lease agreement showing deposit amount; bank statement or cancelled check showing deposit payment and date; the postmarked envelope from any itemized statement (to prove whether it arrived within 14 days); your certified mail demand letter receipt.
Chicago-specific documents: Written receipt for deposit showing bank name, address, and account (last 4 digits) — required within 2 business days under RLTO. Annual interest payment notices (or records showing they were never sent). DHCR/RLTO registration status for rent-controlled units.
Condition documentation: Move-in and move-out photos (timestamped). Any move-in inspection form signed at the start of the tenancy. Texts or emails where the landlord acknowledged the unit was in good condition at any point during the tenancy. Repair requests you submitted that show pre-existing conditions the landlord was already aware of.
