An Illinois sublease agreement enables a tenant to rent out all or a portion of their rental unit to another individual, referred to as a “subtenant” or “sublessee.” The sublease agreement defines the subtenant’s liability to the original tenant, the “sublessor,” as well as their obligation to uphold the provisions of the original lease agreement with the landlord.

There are no laws that permit or prohibit a tenant from subleasing in Illinois; therefore, the sublessor should always get permission from their landlord before entering into a sublease with a subtenant. It’s important to select a suitable candidate for a sublease because even if the sublessee is bound by the duties and obligations of a written contract, the sublessor is liable to the landlord for rent payments, the property’s condition, and all other responsibilities.
