QLD SMOKE ALARMS – Be prepared for the updates!

QLD SMOKE ALARMS – Be prepared for the updates!

There has been confusion of late when Building inspectors are conducting inspections of properties with regards to QLD smoke alarms.  The latest legislative updates pose new obligations on homeowners.

All homes in QLD must have smoke alarms installed for safety under the Building Fire Safety Legislation.

Smoke alarms should be tested annually.  Any smoke alarms that do not operate when tested must be replaced immediately.


When replacing smoke alarms, they must be of a photoelectric type which complies with Australian Standard (AS) 3786.

Replacing Smoke Alarms

Existing smoke alarms manufactured more than 10 years ago must be replaced.  Smoke alarms should have the date of manufacture stamped on them.

Existing hardwired smoke alarms that need replacement must be replaced with a hardwired smoke alarm.

From 1 January 2027, smoke alarms in all dwellings must:
  1. Be photoelectric; and
  2. Not also contain an ionisation sensor; and
  3. Be less than 10 years old; and
  4. Operate when tested; and
  5. Be interconnected with every other smoke alarm in the dwelling so all activate together.

Smoke alarms must be installed on each storey:

  • In each bedroom; and
  • In hallways which connect bedrooms and the rest of the dwelling; or
  • If there is no hallway, between the bedrooms and other parts of the story; and
  • If there are no bedrooms on a storey, at least one smoke alarm must be installed in the most likely path of travel to exit the dwelling.

Smoke alarms must be hardwired or powered by a non-removable 10-year battery.

Failing to comply with the new laws may result in a fine of $609.50 for each provision which is not followed.
