Top issues we find in Illinois leases.

Our AI scans your lease clause by clause against Illinois statutes and flags these common violations.

Issue 01

Security Deposit Return Act violations

Under 765 ILCS 710, Illinois landlords must return deposits within 30 days (45 days in Chicago) with an itemized statement. Failure to comply entitles the tenant to twice the deposit amount plus attorney fees.

Issue 02

Chicago RLTO non-compliance

Chicago's Residential Landlord and Tenant Ordinance imposes additional requirements including a 1.5-month deposit cap, mandatory interest payments on deposits, and specific disclosure requirements. Many Chicago leases fail to comply with these local rules.

Issue 03

Missing interest payments on deposits

In Chicago and several other Illinois municipalities, landlords must pay annual interest on security deposits. The interest rate is set each year by the city. Failure to pay interest can result in penalties equal to twice the deposit.

Issue 04

Illegal waiver of tenant remedies

Illinois law prohibits lease provisions that waive tenant rights to proper notice, habitability, or the protections of the Security Deposit Return Act. Any such waiver is void, even if the tenant signed it voluntarily.

Understanding Illinois Lease Law in 2026

Illinois tenant protections operate at both the state and local level, creating a layered system that landlords frequently fail to navigate correctly. At the state level, the Security Deposit Return Act (765 ILCS 710) governs how landlords must handle security deposits. Landlords must return the deposit within 30 days of the tenant vacating, along with an itemized statement of any deductions and paid receipts or estimates for repair costs.

The penalty for non-compliance is substantial: tenants can recover twice the amount of the deposit plus reasonable attorney fees. This penalty applies if the landlord fails to return the deposit on time, fails to provide an itemized statement, or makes deductions that are not supported by actual damages beyond normal wear and tear.

Chicago RLTO: Additional Protections for City Tenants

If you rent in Chicago, the Residential Landlord and Tenant Ordinance (RLTO) provides protections that go well beyond state law. Chicago landlords cannot charge more than 1.5 months of rent as a security deposit. They must hold the deposit in a federally insured interest-bearing account and pay the tenant interest annually. They must provide written receipts for deposits and disclose the bank name, account type, and interest rate.

The RLTO also requires landlords to attach a city-published summary of the ordinance to every lease. Failure to do so gives the tenant the right to terminate the lease. The penalties for RLTO violations can include twice the deposit amount, attorney fees, and in some cases the right to withhold rent equal to twice the deposit.

Why Illinois Tenants Need a Lease Analyzer

The overlap between state law and local ordinances in Illinois makes lease compliance particularly complex. A lease that is legal in downstate Illinois may contain multiple violations of the Chicago RLTO. LeaseGuard's AI checks your Illinois lease against both 765 ILCS 710 and applicable local ordinances, including the Chicago RLTO, Evanston's tenant protection rules, and Oak Park's rental regulations. The free scan identifies critical compliance gaps, and the full $4.99 report provides statute-specific citations, risk severity ratings, and a ready-to-send negotiation letter.
