The Chicago Residential Landlord and Tenant Ordinance (RLTO) provides extensive tenant protections including mandatory interest on security deposits, required move-in inspections, and strict disclosure requirements.
A written lease agreement is essential for any residential rental in Illinois. It documents the agreed rent amount, lease term, security deposit, tenant obligations, and the landlord's maintenance responsibilities providing both parties with a clear record that can be enforced in court if necessary. Verbal lease agreements are generally enforceable in Illinois but create significant evidentiary problems if a dispute arises.
Every Illinois lease should include at minimum: the names of all tenants and the landlord, the property address, the lease term and rent amount, the security deposit amount and terms, a description of which utilities each party is responsible for, pet policies, entry notice requirements (typically 24 to 48 hours), and the procedures for lease termination and deposit return. Including Illinois-specific required disclosures at the time of signing protects the landlord from future claims of inadequate notice.
Illinois has no statewide security deposit interest requirement, but Chicago mandates 5% annual interest. Many Illinois cities have additional local ordinances. Landlords statewide must provide written notice of deposit deductions.
Landlords who fail to return the security deposit within the statutory deadline or who fail to provide an adequate itemized statement may forfeit the right to any withholdings and may be liable for additional penalties under Illinois law. Best practice is to document the property's condition at both move-in and move-out with a signed checklist and date-stamped photographs.

Illinois law limits security deposits to No statutory limit (outside Chicago). Landlords must return the deposit within 30 days of lease termination along with an itemized written statement of any deductions. Deductions are permitted only for unpaid rent, damage beyond normal wear and tear, and other specific charges authorized by the lease. Normal wear and tear cannot be deducted. Landlords who fail to comply with deposit return requirements may forfeit the right to any withholdings and may be liable for additional damages.
For month-to-month tenancies in Illinois, the required notice period is 30 days (month-to-month). This notice must generally be given in writing and delivered according to the method specified in the lease or required by state law. For fixed-term leases, the lease simply ends on the specified date unless both parties agree to renew. Landlords should review the specific notice requirements in the lease and state statutes before serving notice, as failure to provide proper notice can invalidate an attempted termination.
All residential leases in Illinois must include the federally required lead-based paint disclosure for properties built before 1978. Illinois-specific disclosures may include landlord identity and contact information, the location or financial institution holding the security deposit, details about utilities and who is responsible for payment, and any known property conditions or hazards. Failure to provide required disclosures can expose landlords to liability and may affect their ability to terminate the tenancy.
During a fixed-term lease in Illinois, the landlord generally cannot raise rent unless the lease specifically allows for increases. For month-to-month tenancies, the landlord may increase rent with proper written notice. The Chicago Residential Landlord and Tenant Ordinance (RLTO) provides extensive tenant protections including mandatory interest on security deposits, required move-in inspections, and strict disclosure requirements. Landlords should verify whether any local ordinances in their city or county restrict rent increases, as some jurisdictions have enacted local rent stabilization measures.
Landlords in Illinois are required to maintain rental properties in a habitable condition -- meaning the property must have adequate structural integrity, weatherproofing, plumbing and heating in good working order, and protection from rodents and vermin. Tenants must promptly notify landlords of maintenance issues in writing. If a landlord fails to make necessary repairs within a reasonable time after written notice, tenants may have remedies including repair-and-deduct, rent withholding (in limited circumstances), or termination of the lease.
