Illinois Security Deposit Rules (2026)

Illinois has a two-stage framework for property-damage deductions. A landlord withholding from a deposit for damage generally must provide an itemized statement and cost support within 30 days, while failure to provide the required statement and receipts can trigger a full-return deadline within 45 days.

What to collect for an Illinois deposit dispute

  • Move-out date and the date the right of possession ended.
  • Itemized damage statement and delivery record.
  • Receipts, estimates and any later paid receipts.
  • Lease sections that specify cleaning, repair or replacement costs.
  • Move-in and move-out photos or inspection records.

Local law can matter

Illinois statewide law is only one layer. Chicago and other municipalities may have local landlord-tenant rules that add requirements or remedies, so property location should be checked separately.

Check local law too. Illinois statewide law is the baseline. Chicago and other municipalities can add renter protections, deadlines or remedies.
