Queensland smoke alarm rules, explained simply
From 1 January 2027 every home in Queensland needs compliant smoke alarms. Here's what that means, who it applies to and what it costs.
What every home needs
- Photoelectric smoke alarms that comply with AS 3786-2014
- Interconnected, so all alarms sound together (wired, wireless, or a mix)
- In every bedroom, in hallways connecting bedrooms to the rest of the home, and on every storey (on a storey without bedrooms, in the most likely path out)
- Hardwired to mains power, or powered by a 10-year non-removable battery
- No alarm older than 10 years, and none that fails testing
Deadlines
Already in force: homes being sold, and rental homes at each new or renewed lease.
1 January 2027: all other homes, including owner-occupied houses, townhouses and units.
Do I need an electrician?
Hardwired (240-volt) alarms must be replaced with hardwired alarms, installed by a licensed electrician. Homes with battery alarms only can switch to interconnected alarms with 10-year non-removable batteries, which you can fit yourself (see our DIY guide). Placement rules still apply, so many homeowners prefer an electrician to do it properly.
Where alarms go
On the ceiling, ideally near the centre of the room, at least 300 mm from walls, corners and lights, and at least 400 mm from air-conditioning vents and fan blades.
What it costs
As a rough guide, A$100 to A$250 per alarm supplied and installed, so about A$400 to A$1,000 for a typical 3 to 4 bedroom home. Get a fixed quote before work starts.
Landlords and tenants
Landlords must install compliant alarms and test them within 30 days before each tenancy starts or is renewed. Tenants should test them at least every 12 months.
