Saskatchewan's Building Code Regulations require every building with a residential occupancy to have carbon monoxide (CO) and smoke alarms installed by July 1, 2022, regardless of when the building was constructed.

Residential occupancies are rented or owned buildings with sleeping quarters such as:

• houses (both urban and rural)
• duplexes
• apartments
• condominiums
• townhouses
• motels and hotels

Building owners are required to install independent smoke and CO alarms or combination devices that detect both smoke and CO. The number and location of devices must conform to requirements of the National Building Code of Canada (NBC).

Devices with a 10-year tamper resistant battery are permitted to meet this requirement provided the building is not already required by the NBC or a municipal bylaw to have a hardwired CO and smoke alarms.
