Smoke Alarm Requirements for New Construction…

January 1, 2015

If you are building or renovating a new home under a building permit, be aware of the new smoke alarm amendment to the 2014 Ontario Building Code O. Reg. 332/12 effective January 1, 2015.

All smoke alarms must now be equipped with a visual signaling component that meets NFPA 72, “National Fire Alarm and Signaling Code”.

Since 2014 under the OBC, smoke alarms are also required in each sleeping room and between the sleeping rooms and on every storey.  Smoke alarms must also be installed in hallways that serve a sleeping room.

The smoke alarm installation requirement for existing buildings has not changed.  Under the current Ontario Fire Code O. Reg. 213/07, homes in Ontario must have a working smoke alarm on every storey and outside all sleeping areas.
