Plain English

Section 735 § 1.1 of the Illinois Compiled Statutes establishes the foundational vocabulary used throughout the Act governing utility service in rental housing. It defines key terms such as "landlord," "tenant," "agreement," "utility service," "utility company," and the distinction between individually metered and master metered utilities. These definitions set the scope of who and what is covered by the Act's requirements, ensuring that the rules apply broadly to owners, agents, lessors, and occupants across various rental arrangements. The definitions also clarify that utility service encompasses electric, gas, water, and sanitary services provided by any supplier, including municipalities.

For Property Managers

Property owners, agents, and lessors covered under 765 Ill. Comp. Stat. 735 § 1.1 should be aware that the Act's definitions are intentionally broad, capturing a wide range of rental arrangements and utility configurations. Compliant operators generally understand whether their building operates under individual or master metering, as this distinction affects how utility-related obligations are applied throughout the rest of the Act. Recognizing that "agreement" encompasses oral understandings and informal contracts—not just written leases—helps operators account for all arrangements that may fall under the Act's scope.

For Tenants

Under 765 Ill. Comp. Stat. 735 § 1.1, the term "tenant" is defined broadly to include occupants of buildings or mobile homes under either a lease or a periodic tenancy, meaning a wide range of living arrangements may qualify for the Act's protections. Tenants should be aware that the type of metering in their building—individual or master—can affect how utility-related rights and responsibilities are allocated under the Act. Those who believe their situation falls within these definitions and have concerns about utility service arrangements may benefit from consulting a tenant-rights organization or reviewing the full Act for provisions that apply to their circumstances.
