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, checks the deposit and late fee against Illinois's statutory caps, 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 and the number of units in the building, 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), whether the building was built before 1978 (federal lead-paint rule), and the answers to your state's disclosure questions (for example whether the property is in a FEMA flood zone — check msc.fema.gov).

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 together with every attachment listed at the end of the lease, and complete a move-in inspection checklist with photos. Keep the signed lease for at least four years after the tenancy ends.

Frequently asked questions

How much security deposit can a landlord charge in Illinois?

Illinois has no statutory cap on security deposits (No statutory limit); the amount must be stated in the lease and returned per statute.

When must the deposit be returned in Illinois?

Within 45 days after the tenant moves out, with an itemized statement of deductions (765 ILCS 710/1(a)).

Does this lease include the disclosures Illinois requires?

Yes. The Disclosures section asks you the yes/no questions each Illinois statute requires (for example flood zone, sprinklers, mold or bed bugs) and prints the actual statutory statement — in bold or larger type where the law demands it — with its citation, plus the federal lead-paint notice for pre-1978 buildings. Forms that must be separate documents are listed as attachments.

Is this lease legally binding once signed?

A written lease signed by landlord and all adult tenants is an enforceable contract in Illinois. Electronic signatures are valid under the federal ESIGN Act and the state UETA. No notarization is required for a residential lease.

Can I use this for a month-to-month rental?

Yes — choose 'Month-to-month' in the Term step. The tenant's notice period is set to Illinois's statutory minimum, and the landlord's notice period follows 735 ILCS 5/9-207(b).
