How to use this Residential Lease Agreement in Illinois

A residential lease in Illinois should identify every adult tenant, describe the premises, state the term, the rent and how it is paid, the security deposit and how it will be returned, who pays which utilities, the rules on pets, smoking and subletting, and the disclosures Illinois law requires. This generator walks you through each of those items in order and drafts the clauses for you.

Before you start, gather: the legal names and mailing addresses of the landlord and all tenants, the property address, the move-in date, the rent amount and due day, the deposit amount and the bank where it will be held (some states require this), and whether the building was built before 1978 (federal lead-paint rule).

After you preview the document, download the PDF, have every adult tenant and the landlord sign (electronic signatures are valid), give each party a copy, and complete a move-in inspection checklist with photos. Keep the signed lease for at least four years after the tenancy ends.
