Illinois Sublease Agreement Overview
In Illinois, a sublease agreement allows an existing tenant (sublessor) to rent all or part of their rental unit to another person (sublessee) for a portion of the remaining lease term. Illinois does not have a statewide subletting statute, but Chicago's RLTO provides that landlords cannot unreasonably withhold consent to subletting.
Chicago's Residential Landlord and Tenant Ordinance provides stronger subletting protections than state law.
A properly drafted Illinois sublease agreement protects all three parties — the landlord, the original tenant, and the sublessee — by clearly defining the terms of the subletting arrangement and ensuring compliance with IL law.
