Smoke alarms - Compliance for Residential projects

Your support for a stress free approval.


Ensure safer homes for Queenslanders

To meet your legislative requirements, all smoke alarms need to comply with NCC Vol 2 2019 Fire safety - Part 3.7.5.


For new Class 1 buildings (and or Class 10a private garage above/ below the Class 1 building) smoke alarms will be required

- Photoelectric, hardwired and powered by the mains source

- interconnected when there is more than one alarm

- both in and outside of the bedrooms.


Building designers and architects, the updated NCC reference is 3.7.5.


Both the NCC guidelines and building regulations apply.


  • The building regulation legislation for Queensland outlines installation specifications.

  • QBCC provides updates around conforming products.

  • HIA has summarised updated NCC 2019 changes and related separating wall / smoke alarm information here.
