Itemize deposit deductions by day 30 after move-out, or refund in full by day 45. Illinois landlords who keep any part of a security deposit for damage must deliver an itemized statement of the damage and the cost of each repair, with paid receipts or estimates, in person, by postmarked mail, or by email to a verified address the tenant provided, within 30 days after move-out (or after the tenant's right of possession ends, if later), and otherwise must refund the full deposit within 45 days of move-out, because a court can award twice the deposit plus court costs and attorney fees when the statement is skipped or made in bad faith.
