Changes to the building code for smoke detectors in Nova Scotia
For new constructions, a smoke alarm is now required in each bedroom and each level of a house, as per the National Building Code (NBC) and they must be interconnected and must have battery backup.
Smoke alarms (as per ULC 531) can be attached to certified control panels that meet ULC S545. For more information on specific requirements, see rule 184.108.40.206 of the NBC and the Building Code Act and associated regulations.
CO detectors should be installed as per 220.127.116.11 of the NBC.
These installations are regulated by building inspectors; all questions should be forwarded to building inspectors.
