Illinois Rental Lease Agreements | Laws

An Illinois lease agreement is a contract entered into by two parties; an owner/landlord of real property and a tenant. The landlord may be managing a residential rental space or a commercial property available to rent by a business entity. Each type of rental agreement listed below will contain different terms and conditions specific to the rental situation for which they were created. The provisions contained therein should be looked over carefully by prospective tenants before they agree to sign the document. Landlords should check a tenant’s background, such as credit, employment, and rental history, to ensure they are suitable for tenancy.
