How many smoke alarms are required by law?
Every residence is different and you will need to assess your home. The following is suggested as a guide. Alternatively, follow the manufacturer’s instructions:
- A smoke alarm outside each sleeping area and on each level of the home provides a minimum degree of protection from the threat of fire;
- In a single-level home, one alarm may be sufficient (as a minimum) if all the bedrooms connect to a common Hallway;
- Additional alarms are needed in homes with separated sleeping areas;
- Where occupants sleep with bedroom doors closed, install a smoke alarm in each bedroom and the hallway.
Ideal Locations and number required by law:
Between the bedrooms and the rest of the house.

* Minimum by law from 1 July 2007.
Near bedrooms and on every storey of a multi-level house.

* Minimum by law from 1 July 2007.
Additional alarms are needed in homes with separated sleeping areas.

* Minimum by law from 1 July 2007.
Inside the bedroom if you are a heavy sleeper or if you close the door.

* Additional recommendation for added safety (not law).
For advice on the selection, placement and maintenance of smoke alarms contact your local Queensland Fire & Rescue Service fire station or a reputable fire protection company.
