The State of Illinois Public Act 094-0741 requires a carbon monoxide detector by installed within 15 feet of all sleeping rooms of all dwelling units, effective January 1, 2007. This applies to single-family homes, duplexes, townhouses, apartments, hotels and motels. There are penalties for noncompliance.
Types of Detectors
There are various types of detector that can be used:
- Battery powered
- Direct-wired in the building electrical system with battery back up
- Plug in with battery backup
Combination Smoke Detectors
There are some combination smoke detectors that may be used. If you are going to utilize this type of detector, consult the product literature or manufacturer for compatibility with the existing detectors. This requires a different alarm tone for smoke detection and carbon monoxide detection.
Homeowners are responsible for the installation of the detector. If you own or occupy a rental unit, the installation is the responsibility of the landlord.
Hardwiring a Detector
If you are going to hardwire the detector, a building permit (PDF)
may be required. Consult the building department for requirements.
