Illinois Landlord-Tenant Proration Rules
Residential tenancies in Illinois are governed by 765 ILCS Chapter 705 and municipal codes such as the Chicago Residential Landlord and Tenant Ordinance (RLTO). Standard Chicago Association of Realtors (CAR) residential agreements prorate rent on an exact daily schedule.
// Standard Illinois Statutory Formula
Daily Rate = Monthly Rent ÷ Actual Calendar Days
Total Prorate Due = Daily Rate × Days Occupied
Chicago Fair Notice Ordinance
Under Chicago municipal law, tenants with over three years of occupancy are entitled to 120 days of advance notice before lease termination or non-renewal. When moving mid-cycle, rent is prorated strictly through the agreed surrender date.
