An Illinois lease agreement is a document between a landlord and tenant for the use of residential or commercial property in exchange for the payment of rent. The tenant should first view the space and, if interested, should request to submit their credit and background details through a rental application.
Once the landlord has reviewed their credentials and the tenant is approved, the negotiations will begin for rent, security deposits, and the responsibilities of each party.

Concession Granted (765 ILCS 730) – Any concession for rent is required to be mentioned in the lease. When entered into the page, the header with the words “Concession Granted” should be at least one-half (1/2) inches in height on the document.

Radon Disclosure (420 ILCS 46) – The landlord is not required to test for radon, but if they do, and the Landlord finds out that radon exists on the premises, they must relay the information to the tenant. This does not qualify for residences on the third (3rd) floor or higher in a residential complex. In addition, the IEMA-approved Radon Disclosure Pamphlet should be given to the tenant.
Smoke Detectors (425 ILCS 60/3(d)) – It is the responsibility of the landlord to provide smoke detectors throughout the premises.

Interest-Bearing Account (765 ILCS 715) – If the Landlord owns more than twenty-five (25) rental units, they will be forced to place the security deposit in an interest-bearing account to be at least the interest rate in the State of Illinois on the previous December 31 of the most recent year.
