Illinois § 20

§ 20.

Heating and cooling standards. (a) When residential rental property has a cooling system or heating system or both serving the entire premises, including individual dwelling units, the landlord shall comply with the following standards with respect to the individual dwelling units in which tenants live: (1) During the cooling season, June 1 through September 30, cooling systems must operate when the heat index exceeds 80 degrees Fahrenheit. (2) During the heating season, October 1 through May 31: (i) between 6 a.m. and 10 p.m., heat must register at least 68 degrees Fahrenheit when the outside temperature falls below 55 degrees Fahrenheit, and (ii) between 10 p.m. and 6 a.m., heat must register at least 62 degrees Fahrenheit. (b) When residential rental property does not have a premises-wide cooling system that serves individual dwelling units, then the landlord shall provide at least one indoor common gathering space for which a cooling system operates when the heat index exceeds 80 degrees Fahrenheit. All tenants of the residential rental property shall have free access to that cooled space. As used in this subsection, "indoor common gathering space" means a room intended to be used as a place where multiple people can gather, such as a lounge, meeting or conference room, party room, or similar that can accommodate a cooling system. Residential rental property that does not have an indoor common gathering space shall be exempt from this subsection. (c) This Section only applies to residential rental property in which rental or occupancy is limited to persons 55 years of age or older. (Source: P.A. 103-161, eff. 1-1-24.)
