Itemized damage statement with receipts within 30 days after move-out (to keep any deposit for damage) Verified

Deadline: Within 30 days after move-out

To withhold any part of a deposit for damage, deliver an itemized statement of the damage and repair costs, with paid receipts (or estimates, then receipts within 30 more days), within 30 days after the tenant vacates or their right of possession ends, whichever is later.

Applies to: any number of units, when you hold a security deposit · Layer: Illinois · Topic: Security deposit return

"may not withhold any part of that deposit as reimbursement for property damage unless the lessor has, within 30 days of the date that the lessee vacated the leased premises or within 30 days of the date the lessee's right of possession ends, whichever is later,"
ilga.gov
"an itemized statement of the damage allegedly caused to the leased premises and the estimated or actual cost for repairing or replacing each item on that statement, attaching the paid receipts,"
ilga.gov

Notes: 765 ILCS 710/1(a) (as amended by P.A. 103-224, eff. 1-1-24). Bad-faith failure: liability of twice the deposit plus costs and attorney's fees (§1(c)). The current text has no minimum unit count. Chicago's RLTO adds its own rules.
