Residential homes are required to have carbon monoxide alarms on each habitable level. On sale or transfer of a property, a satisfactory inspection is required. In brief, regulations for installing carbon monoxide detectors are as follows:
- Carbon monoxide alarms must be installed on every level of the home, including habitable portions of basements and attics (even if unfinished)
- CO detectors must be installed within 10-feet of any bedroom door
- CO alarms may be battery operated, plug-in with battery back-up, wireless, hardwired low-voltage or a combination smoke and CO alarm
- Non-habitable living space is not required to have CO detectors
- Rental properties must have properly installed and maintained CO alarms in every dwelling unit that has a source of carbon monoxide.
- Check that alarms carry an approval label from an independent testing company such as Underwriterâ€™s Laboratory (UL) or International Approval Service/Canadian Standards Association (IAS/CSA).
