The Building Code Regulations has the following requirements that will come into force on July 1, 2022:
Every building that contains a residential occupancy is required to have smoke alarms installed inside each bedroom, in the bedroom corridor, and each storey without a bedroom. These smoke alarms are permitted to be battery operated. If the building was constructed before June 6, 1988, then the batteries used for the smoke alarms must be 10-year batteries (see photo attached for example of 10-year battery alarm).
Every building that contains a residential occupancy is required to have a carbon monoxide alarm installed inside each bedroom OR within 5 m (16’) of each bedroom door. These carbon monoxide alarms are permitted to be battery operated. If the building was constructed before October 1, 2009, then the batteries used for the carbon monoxide alarms must be 10-year batteries (see photo attached for example of 10-year battery alarm).
What does this mean for owners?
If your house/condo/duplex/etc. is missing smoke and/or carbon monoxide alarms in the locations listed above, then as the owner it is your responsibility to install the missing alarms.
