How does a Illinois tenant dispute a deposit deduction?
Step 1: write a demand letter to the landlord (certified mail, return receipt) requesting the deducted amount, citing 765 ILCS 710 and any specific deductions disputed. Step 2: if the landlord does not respond within a reasonable time (typically 14-30 days), file a small-claims action in the county where the property is located. Filing fees range $30-$100. Step 3: at the hearing, present the move-in checklist, photos, lease, deposit receipt, and the landlord's itemized statement. Up to 2x the deposit amount if the landlord acts in bad faith under 765 ILCS 710. Many Illinois tenants prevail simply because the landlord failed to itemize within the statutory deadline.

This is an informational answer based on 765 ILCS 710 as of early 2026. It is not legal advice. Housing law changes year to year and local ordinances (especially in rent-controlled or rent-stabilized cities) can override or add to state law. For contested cases, consult a Illinois-licensed attorney.
