Carbon Monoxide Detectors

Illinois requires carbon monoxide alarms effective January 1, 2007.

Carbon monoxide (CO) is odorless, colorless, and tasteless. It is produced when any fossil fuel, including natural gas, is burned. When fossil fuels do not burn properly, CO can build up and cause sickness and even death. Carbon monoxide kills about 200 people in the U.S. every year.

As of January 1, 2007, homeowners, landlords, and building owners are required to install carbon monoxide (CO) detectors within 15 feet of rooms used for sleeping. This law applies only to those occupancies that use fossil fuel to cook, heat, or produce hot water, or occupancies that are connected to an enclosed garage.

The carbon monoxide detector may be battery operated, plug-in with battery back-up, or wired into the home's AC power with a secondary battery back-up. It must also bear the label of a nationally recognized testing laboratory and must comply with the most recent standards of the Underwriters Laboratories or the Canadian Standard Association.

For more information about the law, please click see Public Act 094-0741 or contact your local building commissioner.
