Smoke Detector Laws In Western Australia
Understanding Western Australia’s smoke detector laws is essential for homeowners, landlords, and tenants to ensure compliance and, most importantly, fire safety. Since 1997, W.A has required hardwired smoke alarms in new homes, with regulations expanding over the years to cover rental properties and home sales. These laws help protect lives by ensuring properly installed, interconnected, and regularly maintained alarms. While 240V hardwired smoke alarms are the must-have standard, 10-year battery-powered smoke alarms are allowed in specific situations with council approval. In this guide, we break down W.A’s smoke alarm requirements to help you stay compliant and keep your W.A home safe.
Smoke detector laws in Western Australia are derived from the;
W.A Building Regulations 2012 (division 3) which enshrine Building Code of Australia smoke alarm requirements.
W.A Building Regulations 2012 – Smoke Alarms
In 1997, 240V hardwired smoke alarms became compulsory in Western Australia for all newly constructed residential buildings (or residential building extensions). From 2009 onwards this was extended to also include all existing residential buildings, prior to their transfer of ownership, rent or hire.
In Western Australia smoke alarms must;
- be positioned according to the requirements of the Building Code of Australia
- comply with Australian Standard 3786:2014
- be permanently connected to consumer mains power (i.e. 240V hardwired)
- be interconnected, if your home was newly built after the 1 May 2015.
- be less than 10 years from the date of manufacture
Can I Use 10-Yr Battery Smoke Alarms In Western Australia?
YES you can! – W.A Building Regulations 2012 allow the use of 10 year non-replaceable battery powered smoke alarms in certain situations. This may include where mains power is not connected to the building, there is no hidden space to run the necessary wiring for mains powered alarms, and there is no appropriate alternative location – for example, where there is a solid concrete ceiling. It should be noted that formal approval must be obtained by the local council to use 10 year non-replaceable battery powered smoke alarms in these situations.
