About 54.0 percent of occupied homes in the city of Chicago are rented, since the Census Bureau puts the owner occupied housing rate at 46.0% for 2020 to 2024, and the median gross rent is $1,440 a month (U.S. Census Bureau QuickFacts, Chicago). When a landlord keeps a deposit without a good reason, small claims court is often the most practical way for a renter to get the money back.
This guide explains which court hears small claims in Chicago, the dollar limit, filing fees, the Illinois deposit rules a judge will look at, and how to prepare.
Illinois small claims and deposit rules
Illinois small claims cover claims of $10,000 or less (Illinois Courts, How to File & Serve a Small Claims Complaint). Any person 18 or older may file a small claims case with or without a lawyer; a corporation must be represented by a lawyer (Illinois Courts, How to File & Serve a Small Claims Complaint). Under the Illinois Security Deposit Return Act, a landlord who wants to deduct for damage must send an itemized statement within 30 days after the tenant moves out, or else return the full deposit within 45 days (765 ILCS 710/1(a)).
If the court finds the landlord failed to itemize or did so in bad faith and did not return the deposit on time, the landlord owes twice the deposit due plus court costs and reasonable attorney’s fees (765 ILCS 710/1(c)).
Chicago court details
Chicago’s Residential Landlord and Tenant Ordinance requires the landlord to return the deposit within 45 days after the tenant vacates (Chicago Mun. Code § 5-12-080(d)). A Chicago landlord who violates the deposit rules owes the tenant two times the security deposit plus interest (Chicago Mun. Code § 5-12-080(f)(1)).
What is at stake at the median rent
The median gross rent in the city of Chicago is $1,440 a month (U.S. Census Bureau QuickFacts, Chicago). A deposit equal to one month’s rent would be about $1,440, and where state law adds a penalty for a wrongfully kept deposit, the total claim can be several times that. Check the court’s dollar limit above before you file.

Before you file: send a demand letter
Most courts expect you to try to resolve the dispute first, and a clear demand letter often gets results on its own. State the amount you are owed, the deadline the landlord missed or the deductions you dispute, the law that applies, and a date by which you expect payment. Send it in a way you can prove and keep a copy for court.
Date: 2026. To: [landlord]. Re: Security deposit for [address]. I moved out on 2026 and gave my forwarding address on 2026. I have not received [my deposit] [an itemized statement] [a refund of the amounts I dispute]. Under [state law], please pay [amount] by 2026. If I do not receive payment, I intend to file in small claims court. Sincerely, [name].
What to bring to court
- Your lease and any addendums.
- Proof you paid the deposit, such as a receipt or bank record.
- Move in and move out photos or video, with dates.
- Your move in checklist, if you had one.
- Your notice to move out and proof of your forwarding address.
- The landlord’s itemized statement, if any, and your demand letter.
- Copies of everything for the judge and the landlord.
How a small claims case usually works
- File a claim with the court clerk and pay the filing fee, or ask whether you qualify for a fee waiver.
- Have the landlord served with the claim, following the court’s rules.
- Prepare a short, dated timeline and organize your evidence.
- Attend the hearing on time and present your case calmly and briefly.
- If you win and the landlord does not pay, ask the clerk about collecting the judgment.
Presenting your case
Judges in small claims hear many cases a day. Start with a one or two sentence summary of what you are asking for and why, then walk through your timeline with the key documents. Focus on whether the landlord met the legal deadline, whether each deduction was for damage beyond normal wear and tear, and whether the landlord followed the required steps. Answer questions directly and avoid interrupting.
If the landlord claims you owe more
A landlord may file a counterclaim for unpaid rent or damage above the deposit. Bring evidence that responds to likely claims, such as rent receipts and photos of the unit’s condition. If the counterclaim is larger than you expected, ask the court whether you can get more time to prepare.
Mediation
Many courts offer free or low cost mediation before or on the day of the hearing. A mediator helps both sides reach an agreement but does not decide the case. If you reach a deal, make sure it is written down and states the amount, the due date, and what happens if payment is late.
Mistakes to avoid
- Waiting too long. Statutes of limitation apply, and evidence fades.
- Suing the wrong party. Use the landlord’s or management company’s exact legal name, which may appear on the lease or in public records.
- Forgetting service. The case cannot go forward until the landlord is properly served.
- Bringing only originals. Bring copies for everyone.
Collecting a judgment
Winning a judgment does not always mean immediate payment. Ask the landlord to pay by a set date, and if that fails, ask the court clerk about collection tools available in your state, such as liens or garnishment. Keep records of every payment received.
Build your evidence file
Landlord and tenant disputes are usually decided by documents. Keep these together from the day you sign:
- The signed lease, every addendum, and every renewal.
- Receipts or bank records for the deposit and each rent payment.
- Dated photos and video of every room at move in and move out.
- Copies of every repair request and the landlord’s replies.
- Every notice you send or receive, with proof of delivery.
Keep copies somewhere other than your phone, such as an email to yourself, so they survive a lost device.
Is it worth going to court?
Compare the amount at stake, including any statutory penalty, with the filing fee, service costs, and time off work. In many states a landlord who wrongfully keeps a deposit can owe more than the deposit itself, as described above, which can make a small claims case worthwhile even for modest amounts.
Language access and accommodations
Courts generally provide interpreters and disability accommodations for people who need them. Ask the clerk well before your hearing date and note the request in writing.
Building a timeline
A one page timeline is often the most useful thing you can hand a judge. List the date you signed the lease, the deposit amount and date paid, the date you gave notice, your move out date, the date you sent your forwarding address, the landlord’s deadline, the date you received any statement, and the date of your demand letter. Next to each entry, note the document that proves it.
Fee waivers
If you cannot afford the filing fee, ask the clerk whether you qualify for a fee waiver. Courts commonly consider whether you receive certain public benefits or have income below a set level. The application is usually a short form, and approval can cover the filing fee and sometimes service costs.
Serving the landlord
After you file, the landlord must receive formal notice of the case. Courts typically allow service by a sheriff or constable, a professional process server, or certified mail, depending on local rules. Use the address on your lease or the management company’s registered address, and keep the proof of service the court gives you. The hearing cannot go forward without it.
Build an index that lets another person find a document
An organized folder should make it possible to locate a document without hearing its entire history first. Create an index with a reference number, a short description, the document date, and the filename. Use separate entries for a payment record, a photograph, and a message even if they concern the same event. A reference such as item 04 is more useful when it consistently points to one file rather than an unsorted bundle.
Keep original records separate from working notes. If you annotate a copy, label it as annotated and retain the unchanged version. When several messages belong to one conversation, keep enough context to show the sequence and who sent each message. Do not silently change dates or descriptions to make an account easier to follow. Mark an uncertain date as uncertain and explain where the estimate came from.
For a hypothetical arithmetic check, suppose your list contains three disputed amounts: $80, $125, and $45. The sum is $250. Keep the underlying document for each amount alongside that calculation. If one item later changes, update the working total and retain the earlier version with its date. The arithmetic does not establish that an amount is recoverable or that a document will be accepted; it only helps prevent a copying or addition error.
Before sharing the folder, open every attachment and check that the index points to the intended file. Make a separate copy with unrelated private information removed where appropriate, while preserving the originals. Follow the recipient’s actual instructions for file formats and delivery rather than assuming a personal filing system meets its requirements. Keep a short list of questions about any missing documents. This is an administrative preparation method, not guidance on filing deadlines, service, admissibility, claims, remedies, or the result of a court case.

Frequently asked questions
Do I need a lawyer for small claims court in Chicago?
Usually not. Small claims courts are designed for people representing themselves, and some states limit or bar lawyers, as described above.
How long do I have to sue over a deposit?
Deadlines vary by state. File as soon as the landlord’s deadline to return the deposit has passed and your demand letter has gone unanswered.
Can I get the filing fee back?
In many courts, the winning party can ask the judge to add court costs to the judgment. Ask the clerk how that works.
