Get Your Security Deposit Back in Illinois

Start based on your situation

• Deposit not returned
• Illinois security deposit deadlines
• Unfair deductions or missing receipts
• Avoid problems before move-out

What Illinois law is built around

For property-damage deductions, Illinois generally requires an itemized statement within 30 days after the later of move-out or the end of your right of possession. The statement should identify the alleged damage and repair or replacement cost, with paid receipts or copies.

If the landlord does not furnish the required statement and receipts, the deposit generally must be returned in full within 45 days after you vacated. If estimates are used, follow-up receipts are part of the record.

Illinois local ordinances, especially in Chicago and some municipalities, may add stronger rules. This statewide guide focuses on ordinary Illinois residential security deposit return issues.

This is a sequence, not one magic letter

One letter can help, but Illinois deposit disputes often need a clearer sequence.

1. Document move-out, possession return, your mailing address, and deposit-response instructions
2. Send a firm deposit-due notice after the relevant Illinois deadline passes
3. Escalate with 765 ILCS 710/1, the missing or incomplete itemization, and your proof
4. Send a final demand before deciding whether to file in Circuit Court small claims

Step 1 is preventive. It signals that you are organized, gives the landlord a clean address for the deposit response, and helps build the record before the dispute escalates.
