Most residential leases and rental agreements in Illinois require a security deposit. This  is a dollar amount, usually one month's rent, that's intended to cover damage to the premises beyond normal wear and tear, and to cushion the financial blow if a  tenant skips out early on the lease without paying. Here’s a summary of Illinois landlord-tenant laws that cover the use and return of security deposits.

Does Illinois law limit how much a landlord can charge a tenant for a security deposit?

No. In Illinois, there's no statutory limit on security deposits at the state level, but check your city and county laws to see if your municipality has set a cap on security deposits for residential rentals.

What about when a tenant moves out? What is the deadline in Illinois for returning a security deposit?

Under Illinois law, for properties with five or more units, a landlord must return the tenant's security deposit within 30 to 45 days after the tenant moves out -- depending on whether the tenant disputes deductions taken out of the security deposit or if an itemized statement and receipts are provided by the landlord.

Is there additional information that Illinois landlords must provide to tenants when it comes to security deposits in Illinois?

Yes. In addition to complying with Illinois laws on security deposit limits and how (and when) the deposit must be returned to tenants, landlords in Illinois must pay interest on security deposits held for more than six months if they rent 25 or more units in either a single building or a complex located on contiguous properties.
