Your Illinois landlord has 30 days to send an itemized list of deductions and 45 days to return the deposit, and since 2024 that applies to all residential landlords (765 ILCS 710/1). If a court finds the landlord refused to send the statement or sent it in bad faith, and also failed to return the money on time, the landlord owes twice the deposit due, plus court costs and reasonable attorney's fees.
This guide gives you the steps in order: what to document, how to count the deadlines, what your landlord can and can't deduct, what your demand letter should say, and when to file in small claims court. It also covers the Chicago ordinance and what happens if your building has been sold.
What should I check first to get my Illinois deposit back?
Start with your move-out date, your address on file with the landlord, and whether you've received an itemized statement. Those three facts decide which deadline has passed and what you can demand. Work through this list in order:
- Write down the date you moved out and the date your lease or right of possession ended.
- Give your landlord a mailing or email address in writing, and keep a copy.
- Collect your proof: the lease, proof you paid the deposit, move-in and move-out photos, and any messages about the unit's condition.
- Mark day 30 and day 45 on a calendar.
- Compare any itemized statement against the rules in the next sections.
- Send a dated demand letter that cites 765 ILCS 710/1.
- File in small claims court if the letter doesn't work.
The address step matters more than it looks. Under the statute, "the lessor shall not be held liable for any damages or penalties as a result of the lessee's failure to provide an address." If you moved out without leaving one, send it today. Don't assume your landlord will track you down.
Photos are your best evidence if the dispute is about the unit's condition. If you've already handed back the keys and didn't take any, gather what you still have: move-in photos, repair requests, and messages from around the time you left.
How long does an Illinois landlord have to return a deposit?
Your landlord has 30 days to itemize deductions and 45 days to return the deposit. Public Act 103-224 removed the old 5-or-more-units limit effective January 1, 2024, so a landlord with a single rental is covered too.
The two clocks don't start in quite the same place. The 30-day statement deadline runs from the later of the date you vacated or the date your right of possession ended. The 45-day return deadline runs from "the date that the lessee vacated the premises." If you moved out before your lease ended, those dates can differ, so write down both.
A landlord can deliver the statement in person, by postmarked mail to your last known address, or by email to a verified address you provided. Mail is judged by its postmark, so a letter that arrives a few days after day 30 may still be on time. Check the envelope and keep it.
| Rule | Illinois (765 ILCS 710/1) | Chicago (Mun. Code § 5-12-080) |
|---|---|---|
| Itemized statement | 30 days from the later of vacating or the end of the right of possession | Within 30 days, delivered or mailed to your last known address |
| Return of the deposit | 45 days from the date you vacated | 45 days from the date you vacated |
| Remedy | Twice the deposit due, plus court costs and reasonable attorney's fees, after a court finding | Two times the deposit plus interest |
If you rent in Chicago, read § 5-12-080 alongside the state act and check whether the ordinance covers your building, because it doesn't reach every rental. If you're not sure, cite both in your letter.
What can an Illinois landlord deduct from my deposit?
A landlord can hold a deposit "to secure the payment of rent or to compensate for damage to the leased premises," so unpaid rent and real damage are the two main deductions. Ordinary aging of the unit isn't damage. Where a written lease sets specific costs, the statute says they "shall be for damage beyond normal wear and tear and reasonable to restore."
The section doesn't give you a list of what counts as normal wear, so expect to argue it from the facts. The usual line is between gradual use and a specific event: carpet worn thin along a walking path versus a burn hole. That's an illustration, not statutory language, but your photos and the length of your tenancy are what make the argument.
To keep money for property damage, the landlord has to follow the statement rules. The statement must list each damaged item and its estimated or actual repair or replacement cost, with paid receipts. Check yours against these points:
- Estimate only? Paid receipts are due within 30 days after the estimate was sent.
- Landlord did the work personally? The landlord can charge the reasonable cost of that labor, so ask how the figure was reached.
- A charge taken from the lease? For a component that won't be replaced, the statement has to cite the lease amount and include the lease pages.
- No receipts? If they're unavailable through no fault of the landlord, the landlord must give an itemized list of costs, other evidence of cost, and a verified statement explaining why.
Without a compliant statement, the rule is direct: the landlord "shall return the security deposit in full within 45 days of the date that the lessee vacated."
What should my Illinois deposit demand letter say?
Your letter should state the facts, cite 765 ILCS 710/1, name the amount you want, and set a date to pay. Keep it to one page and stick to what you can prove. It's your best chance to get paid without going to court, and it becomes an exhibit if you do.
Include these points:
- The rental address, your move-out date, and the deposit amount.
- Whether you received an itemized statement, and if so, which deductions you dispute and why.
- The deadlines: 30 days for the statement and 45 days for the return, citing 765 ILCS 710/1.
- The remedy: twice the deposit due, plus court costs and reasonable attorney's fees, where a court makes the required findings.
- A specific payment date and where to send the money.
- Your current mailing address and email address.
Send it in a way you can prove, such as certified mail with a return receipt, and keep a copy. Stay factual. A calm letter reads well to a judge later, and an angry one doesn't help you.
When can I sue for double my deposit in Illinois?
You can claim double when the landlord refused to supply the itemized statement or supplied it in bad faith, and also failed or refused to return the amount due on time. A court has to make that finding. The penalty isn't automatic just because a deadline passed, and the award is "twice the amount of the security deposit due," with court costs and reasonable attorney's fees on top.
"Due" matters. If the landlord had a valid deduction for part of the deposit, the double is figured on what was actually owed to you, so a landlord who kept $200 of real damage isn't in the same spot as one who kept everything for nothing. Inflated or invented charges are the sort of facts you'd point to when arguing bad faith, so bring the receipts, or point out that there aren't any.
If the demand letter doesn't work, small claims court is the last step, and it's where a deposit dispute is usually filed in Illinois. Your county circuit clerk's office can tell you the current limit, fees and forms. Bring the lease, proof of the deposit, your photos, the statement if there was one, and a copy of your letter with the mailing receipt.
What if my Illinois building was sold or foreclosed while I lived there?
You can still recover the deposit, and you may have more than one party to pursue. Section 1.1 of the Security Deposit Return Act makes the new owner liable to you for the deposit, including statutory interest or prepaid rent, and the seller stays jointly and severally liable. Send your demand letter to both if you know how to reach them.
Foreclosure has its own section. Section 1.2 addresses deposits transferred to a holder of a certificate of sale or deed, or a purchaser of foreclosed property. Read 765 ILCS 710/1.2 against your own facts, and ask who received your deposit in the transfer.

What happens if my Illinois landlord never sends an itemized statement?
The landlord must return the full deposit within 45 days of the date you vacated, under 765 ILCS 710/1. Without a compliant statement, the landlord can't withhold money for property damage. If the deposit also doesn't come back on time, you can ask a court to find the landlord liable for twice the amount due. Court costs and reasonable attorney's fees are added if you win on that basis.
Does the Illinois deposit law apply if my landlord only owns one rental?
Yes. Public Act 103-224 removed the 5-or-more-units limit effective January 1, 2024, so all residential landlords are covered. An older article that says small landlords are exempt is out of date. Cite 765 ILCS 710/1 in your letter and mention the change if your landlord raises the old rule.
Can my landlord send the itemized statement by email?
Yes, if it goes to a verified email address you provided. The statute also allows delivery in person or by postmarked mail to your last known address. Keep the email or the envelope, because the date matters if you later argue the statement was late. It's also wise to confirm your current addresses in writing when you move out.
Do I need a lawyer to get my deposit back in Illinois?
Not for the demand letter, and many people handle a deposit dispute in small claims court themselves. The clerk's office at your county circuit court can explain the current limit, fees and forms. If you win a double award under 765 ILCS 710/1, reasonable attorney's fees are part of it, which can make a lawyer more practical than you'd expect. This guide is general information, not legal advice for your situation.
