Leases & legal documents
Illinois Residential Lease Agreement
Illinois rental law varies significantly between Chicago and the rest of the state — and your lease should reflect where your property is. Chicago’s RLTO caps deposits at 1.5 months’ rent and requires landlords to pay annual interest on deposits held more than 6 months, a rule that doesn’t apply elsewhere in Illinois. Create a compliant Illinois lease through RentRisk, powered by Rocket Lawyer.
