Illinois Residential Lease Agreement Overview
Illinois's landlord-tenant law is governed by Illinois Landlord and Tenant Act (765 ILCS 705 & 735). Illinois is generally considered a tenant-friendly state with no rent control. Security deposits are not subject to a statutory limit, though they must be reasonable. Landlords must return the deposit within 30-45 days after the tenant vacates.
Illinois requires No state statute (Chicago: 2 days' notice) before a landlord enters a rental unit. The state provides a 5 days (Chicago RLTO) grace period before late fees can be assessed. Illinois requires several important disclosures including Lead paint (pre-1978), Radon disclosure, Carbon monoxide detector notice.

Illinois Landlord-Tenant Law Requirements
Eviction Process
Illinois requires landlords to provide written notice before filing for eviction. For nonpayment of rent, a notice to pay or vacate is required (typically 3-14 days depending on the situation). For lease violations, the landlord must provide notice and, in most cases, an opportunity to cure the violation. If the tenant fails to comply, the landlord may file an eviction action (unlawful detainer) in court. As a tenant-friendly state, Illinois provides additional protections during the eviction process.
Habitability Standards
Illinois recognizes the implied warranty of habitability, requiring landlords to maintain rental properties in a livable condition. Landlords must generally maintain structural integrity, provide working plumbing, electrical, and heating systems, ensure adequate weatherproofing, maintain common areas, comply with building and housing codes, and provide working smoke detectors. Tenants are responsible for keeping their unit clean, disposing of waste properly, and reporting needed repairs promptly.
Illinois Security Deposit Rules
Illinois does not impose a statutory limit on security deposits, but courts may find excessive deposits unreasonable. The landlord must return the deposit within 30-45 days after the tenant vacates, along with an itemized statement of any deductions. Illinois requires landlords to pay interest on security deposits held during the tenancy. Allowable deductions typically include unpaid rent, damages beyond normal wear and tear, and cleaning costs if specified in the lease.
Security Deposit Best Practices
Always conduct a move-in and move-out inspection with the tenant, document the property's condition with photos, keep the deposit separate from personal funds, and provide an itemized deduction list when returning the deposit. In Illinois, failure to properly handle security deposits can result in penalties.
Required Disclosures in Illinois
Illinois landlords must provide certain disclosures to tenants before or at the start of the tenancy. Failure to provide required disclosures can result in penalties and may give tenants legal remedies.
