Start with the type of deduction
In Illinois, a landlord may use a security deposit for unpaid rent, damage, and cleaning in appropriate situations, but property-damage deductions must be documented carefully. For damage claims, Illinois generally requires a timely itemized statement and receipts or statutory substitute proof.
Damage beyond normal wear and tear
A damage deduction should be tied to actual damage, not ordinary use. The statement should identify the alleged damage and list the estimated or actual cost for repair or replacement.
Normal wear and tear should not be treated as tenant-caused damage.
Receipts, copies, and estimates
For property-damage deductions, paid receipts or copies should be attached to the itemized statement. If the landlord uses estimates, paid receipts or copies generally must follow within 30 days after the estimate statement.
If the landlord says receipts cannot be produced through no fault of the landlord, Illinois requires substitute proof and a verified explanation.
Lease-specified charges
Some leases list amounts for cleaning, repair, or replacement of specific components. Illinois still limits those charges: they should be tied to damage beyond normal wear and tear and reasonable restoration to move-in condition.
The statement should reference the lease amount and include the applicable lease language.
Unpaid rent and cleaning
Illinois Attorney General guidance recognizes that a deposit may be used to cover unpaid rent, repair damage, and clean the unit after move-out. The statewide Security Deposit Return Act's detailed itemized statement process is framed around property-damage withholdings, so mixed deductions should be reviewed carefully.

If the deduction is vague, unsupported, or mixed with rent or cleaning, ask for the actual basis in writing. The next step should connect the charge to the Illinois record: itemization, receipts or estimates, lease language, photos, and the refund balance still owed.
