Chicago security deposit rules
How Chicago deposit returns generally work
Chicago’s Residential Landlord and Tenant Ordinance generally requires a landlord to return a security deposit, or any balance, with any required interest within 45 days after the tenant moves out, and a landlord who deducts for damage must deliver or mail an itemized statement with repair costs and copies of paid receipts within 30 days. Deposits must be held in a federally insured, interest-bearing Illinois account with a signed receipt, and Municipal Code § 5-12-080(f) provides that a tenant shall be awarded twice the deposit plus interest when a landlord fails to comply, a question a court decides.
Municipal Code of Chicago § 5-12-080(d) requires return of the security deposit or any balance, with required interest, within 45 days after the tenant vacates, less unpaid rent and reasonable repair costs for tenant-caused damage beyond reasonable wear and tear.
To deduct for damage, the landlord must deliver or mail an itemized statement with the cost of each item and copies of paid receipts within 30 days.
Deposits must be held in a federally insured, interest-bearing Illinois account with a signed receipt, and § 5-12-080(f) provides for twice the deposit plus interest when these rules are not followed, as a court determines.
Watch your own deadline: The itemized damage statement goes to your last known address, and the Illinois Security Deposit Return Act says a landlord is not liable for penalties caused by a tenant’s failure to provide a mailing address, so give your landlord a written forwarding address and keep proof. If the landlord paid interest on time but the amount was short, the doubled remedy depends on your written notice of the shortfall; this letter includes that notice.
Check coverage: The ordinance does not govern units in owner-occupied buildings with six or fewer units, short hotel or rooming-house stays, institutional or school housing, employee units, or cooperative units; the Illinois Security Deposit Return Act may also apply, including to excluded units. A pending City Council ordinance would change these deposit rules, including interest and remedies, if enacted; as of October 2, 2026, it had not been enacted.
