Illinois landlord-tenant law is governed by several statutes, including the Illinois Compiled Statutes 765 ILCS 705 (Security Deposit Return Act), 765 ILCS 710 (Security Deposit Interest Act), and 765 ILCS 742 (Residential Tenants' Right to Repair Act). Chicago has its own Residential Landlord and Tenant Ordinance (RLTO) that adds substantial additional protections. Knowing which rules apply is essential.
Illinois does not impose a statewide security deposit cap, but landlords with 25 or more units must pay interest on deposits. Deposits must be returned within 30 to 45 days depending on whether deductions are claimed. Chicago's RLTO requires additional disclosures, specific lease terms, and gives tenants the right to withhold rent for habitability failures. Violations of the RLTO can result in the tenant recovering damages.
SignAI generates your Illinois lease with all required elements — including 765 ILCS 705 deposit return rules, interest payment obligations, radon disclosure, Chicago RLTO compliance where applicable, and Illinois-specific governing law clauses. Each lease is customized to your location and rental situation.

FAQ
Yes. A signed lease is enforceable under Illinois law. The state has multiple statutes governing residential tenancies, and Chicago has the additional RLTO. SignAI's e-signatures are valid under Illinois's Electronic Commerce Security Act (5 ILCS 175) and the federal ESIGN Act.
Landlords who own 25 or more units in Illinois must pay interest on security deposits annually. The interest rate is set by the state each year. In Chicago, all landlords regardless of unit count must pay interest on deposits under the RLTO. Deposits must be returned within 30-45 days with an itemized deduction statement.
The Chicago Residential Landlord and Tenant Ordinance is a city-specific law that provides tenants with additional rights beyond state law. It requires landlords to attach a summary of tenant rights to every lease, mandates interest on deposits, limits late fees, and gives tenants specific remedies for violations. If your rental is in Chicago, your lease must comply with the RLTO.
Illinois requires radon hazard disclosure for all rental properties (420 ILCS 46), lead paint disclosure for pre-1978 buildings, and disclosure of the property owner's identity. Chicago adds further requirements including a bed bug disclosure, a summary of the RLTO, and notice of code violation history.
Illinois landlords must serve a 5-day notice for nonpayment of rent and a 10-day notice for lease violations. If the tenant doesn't comply, the landlord files a forcible entry and detainer action in court. The eviction process typically takes 3-8 weeks. Self-help evictions are illegal, and the Cook County eviction process has additional procedural requirements.
