Security deposit rules in Illinois
When the period starts. Vacancy, end of right of possession, then estimated versus actual cost.
Return and accounting. Damage statement within 30 days after the later of vacancy or end of possession rights. Check later paid-receipt duties and the separate 45-day full-return rule measured from vacancy.
The damage statement and later paid receipts can have separate deadlines. Capture both vacancy and the end of possession rights.
Record whether each amount is actual or estimated. The state interest law uses a different property-size test from the return law. Local requirements may also apply.
