Elgin, IL Rental Property Rules: Repairs & Habitability (2026)

3, 'Heat supply,' amended under Ordinance No. 020, places the heating obligation squarely on the landlord: 'Every owner and operator of any building who rents, leases or lets one (1) or more dwelling unit, rooming unit, dormitory or guest room' and agrees, expressly or by implication, to furnish heat to occupants must supply enough heat during the period from October 1 to May 31 to maintain at least 65 degrees Fahrenheit in all habitable rooms, bathrooms and toilet rooms. 2 ('Residential occupancies'), requires the dwelling's heating system itself to be capable of maintaining that same 65-degree minimum based on the winter outdoor design temperature published in Appendix D of the International Plumbing Code, and specifically bars using cooking appliances as a substitute space heater.

3 carries one exception: when the outdoor temperature drops below the area's winter outdoor design temperature, the landlord is not required to maintain the 65-degree minimum, provided the heating system is running at full design capacity, meaning the excuse only applies if the equipment is already working as hard as it can. 4, extends a similar 65-degree minimum from October 1 to May 31 to indoor occupiable work spaces while they are in use, with exceptions for spaces needing special temperature conditions or vigorous physical activity. 12, the same process used for other habitability defects.
