Illinois security deposit law
How long does a landlord have to return a security deposit in Illinois?
The short answer
Illinois law gives your landlord 30 days if nothing is withheld and 45 days when deductions are claimed after move out to return your deposit, with an itemized statement of any deductions, under 765 ILCS 710 / 765 ILCS 715. Miss the deadline and the landlord loses legal ground and can owe up to 2x the deposit.
Under 765 ILCS 710 / 765 ILCS 715, a Illinois landlord must return your security deposit within 30 days if nothing is withheld and 45 days when deductions are claimed, counted from move out. The return must include an itemized statement listing every deduction.
What the deadline really means: it is not a suggestion. A landlord who misses it weakens any claim to your money and exposes themselves to statutory consequences. Courts can award up to 2x the deposit for wrongful withholding.
How to count the days: the clock starts at move out, not when the landlord gets around to an inspection. Mark the date you handed back keys and gave your forwarding address; that documentation decides deadline disputes.
If the deadline has already passed, the next step is a written demand: a formal letter citing 765 ILCS 710 / 765 ILCS 715, the missed date, and the amount owed. Landlords who ignore informal texts frequently respond to a statute-cited demand sent by certified mail, because it shows you know the deadline and its consequences, and it becomes Exhibit A if you later file in Circuit Court — Small Claims.
