Security Deposit Dispute in Illinois Small Claims Court — Defendant's Guide

Why Security Deposit Cases Land in Small Claims

Security deposit disputes are among the most common small claims cases in Illinois. A tenant moves out, doesn't get their deposit back (or gets less than they expected), and files suit. If the deposit was under $10,000 — which covers the vast majority of residential rentals — the case lands in small claims court under Supreme Court Rule 281.

As the landlord-defendant, you need to understand two things: the Illinois Security Deposit Return Act (765 ILCS 710) and your local municipality's ordinances. Chicago, for example, has its own Residential Landlord and Tenant Ordinance (RLTO) with stricter rules and penalty provisions that go well beyond the state act.

The 30-Day and 45-Day Rules

Under the state Security Deposit Return Act, the deadlines depend on when the tenant vacates and when the right to possession ends:

Within 30 days after the later of move-out or the end of the right to possession: If you withhold money for damage, provide an itemized statement and paid receipts describing the work and its cost. If you initially provide an estimate instead of paid receipts, provide the paid receipts within 30 days after the statement, or a certification of actual costs if your employees did the work. If, through no fault of your own, you cannot produce receipts, provide the itemized cost list, other cost evidence, and the verified explanation required by the Act.

Within 45 days after the tenant vacates: If you do not provide the required itemized statement and receipts, or the permitted substitute information when receipts are unavailable through no fault of your own, return the full deposit.

If you withhold money for damage, the required itemized statement and documentation must be provided on time. If neither the required receipts nor the permitted substitute information are provided, the Act requires the full deposit to be returned within 45 days after the tenant vacates.

Allowable vs. Disallowed Deductions

You can deduct for damage beyond ordinary wear and tear. You cannot deduct for normal wear.

Allowable: Holes in walls (beyond small nail holes), broken fixtures, stained or burned carpet, damage to appliances, excessive cleaning required due to filth, unpaid rent.

Not allowable: Faded paint, minor scuffs on walls, worn carpet from normal use, small nail holes, minor cleaning. These are ordinary wear and tear, and deducting for them invites a losing lawsuit.

The distinction matters because if a judge finds your deductions included ordinary wear and tear, they may award the tenant the improperly withheld amount — and in some jurisdictions, statutory penalties on top.

How to Defend the Claim

Bring your documentation. Your case lives or dies on paper. The strongest defense package includes:

• A copy of the lease showing the deposit amount and the tenant's obligations at move-out
• The itemized deduction statement you sent (keep proof of mailing — certified mail receipt or delivery confirmation)
• Before-and-after photos of the unit, dated with timestamps
• Repair invoices or estimates from contractors
• The move-in condition checklist if you used one (and you should have)

Prepare three copies of everything — one for the judge, one for the tenant, and one for yourself.

Address the timeline first. If you sent the itemized statement and paid receipts within 30 days after the later of move-out or the end of possession — or sent estimates and followed with paid receipts within 30 days after the statement — establish that at the start. It takes the tenant's strongest argument off the table.

Distinguish damage from wear. If the tenant is arguing that the carpet stains were ordinary wear, bring photos showing the stains go beyond what normal use produces. A contractor's estimate or cleaning invoice showing the cost helps quantify the deduction.

Chicago RLTO Complications

If the rental unit is covered by Chicago's RLTO (some housing is exempt, including owner-occupied buildings with six or fewer units), additional requirements apply: the deposit must be held in a federally insured interest-bearing account, and interest must be paid within 30 days after each 12-month rental period. The deposit must be returned with interest within 45 days after the tenant vacates or within seven days after the tenant gives the termination notice described in §5-12-110(g), as applicable. A prevailing tenant may recover damages equal to twice the deposit plus interest, as well as attorney's fees and costs where the RLTO allows them.

If you're a Chicago landlord facing a small claims suit over a security deposit, the RLTO provisions significantly raise the stakes. Make sure your defense addresses both the state act and the city ordinance.

Settlement Considerations

Security deposit cases often settle because both sides have imperfect records. If the tenant has photos showing the unit was clean at move-out and you have photos showing damage, a negotiated split may be cheaper and faster than a hearing — especially when you factor in the appearance fee and a day away from work.

A settlement can be documented as an Agreed Order or Stipulation for Dismissal. If you reach an agreement, have the tenant sign a written settlement and submit it to the judge for approval.
