Illinois Required lease disclosures

What disclosures must a landlord give tenants in Illinois?

Every landlord must disclose in writing before signing if the unit is in a FEMA 100-year floodplain or has known flooding. That disclosure must also appear in the lease, signed by both parties. Lower-level units have added flooding disclosure rules. Starting January 1, 2027, for leases entered into after that date, all non-optional fees must appear on page 1 of the lease or the tenant does not owe them, and the landlord must disclose whether utilities are included in rent. That fee rule does not apply to owner-occupied buildings with 6 or fewer units.
