An Illinois commercial lease agreement is a binding contract for a tenant to lease retail, office, or industrial space. The agreement sets the responsibilities and rights for both landlords and tenants, as well as details about rent, deadlines, penalties, and other items.

The Illinois law that governs commercial leases is the Illinois Uniform Commercial Code, 810 ILCS 5, Article 2A. These types of leases are longer and more complicated than a residential lease, so consulting with a lawyer is advisable.
