RECOMMENDED SMOKE ALARM PLACEMENT   The legislation changes as of January 1st, 2017 will require some residential properties (in some states) to have a photoelectric smoke alarm in each bedroom, in hallways that connect bedrooms and at least one on every storey of a multi level property, in the most likely route to exit. To be compliant, a 3 bedroom, 2 storey house will likely need 5 smoke alarms, possibly more depending on floor layout.
