All Queensland owner-occupiers must have interconnected photoelectric smoke alarms installed in every bedroom, hallway, and on every level of their home. Non-compliance can void your home insurance and attract significant penalties.
If you own a home in Brisbane, the Queensland Government's staged smoke alarm legislation is about to reach its final and most significant milestone. From 1 January 2027, every existing owner-occupied home, unit, and townhouse in Queensland must comply with the new interconnected photoelectric smoke alarm requirements under the Fire and Emergency Services Act 1990.
With the deadline now less than six months away, demand for licensed electricians to complete compliant installations is rising sharply across Brisbane's northside. Here is everything you need to know.
What Does the 2027 Law Actually Require?
The new legislation requires all existing owner-occupied dwellings to have:
- Photoelectric smoke alarms — not ionisation-type alarms, which are no longer compliant
- Interconnected alarms — when one alarm activates, all alarms in the home sound simultaneously
- An alarm in every bedroom
- An alarm in every hallway that connects bedrooms to the rest of the home
- An alarm on every level of the home, including the ground floor if bedrooms are upstairs
- Alarms that are either hardwired or fitted with a non-removable 10-year battery
Rental properties and homes sold after 1 January 2022 were already required to meet these standards. The 2027 deadline brings owner-occupiers into full compliance.
How Many Smoke Alarms Does My Brisbane Home Need?
The number of alarms depends on your home's layout. As a general guide:
| Home Type | Typical Alarm Count | Estimated Cost (Installed) |
|---|---|---|
| 2-bedroom, single-storey unit | 3–4 alarms | $350–$550 |
| 3-bedroom, single-storey house | 4–5 alarms | $450–$650 |
| 4-bedroom, two-storey house | 6–8 alarms | $600–$900 |
| 5+ bedroom, multi-level home | 8–12 alarms | $800–$1,200 |
These estimates include supply of compliant photoelectric alarms, installation labour, and interconnection testing. Hardwired installations (where alarms connect to your home's mains power) sit at the higher end of the range and require a licensed electrician.
Hardwired vs. Battery-Powered: Which Do You Need?
Hardwired Alarms
Hardwired alarms connect directly to your home's 240V mains power with a battery backup. They are the most reliable option and are required in all new builds. If your existing alarms are already hardwired, your electrician will replace them with compliant photoelectric units on the same wiring. This is typically the fastest and most cost-effective upgrade for homes built after 1997.
Battery-Powered Alarms (10-Year Sealed Battery)
For older homes without existing wiring to alarm locations, wireless interconnected alarms with sealed 10-year batteries are a fully compliant and more affordable alternative. These can be installed without any new cabling, making them ideal for heritage-listed homes or properties where running new wiring is impractical.
Why You Need a Licensed Electrician for Hardwired Installations
Under Queensland's Electrical Safety Regulation 2013, any work involving your home's 240V mains wiring — including connecting hardwired smoke alarms — must be performed by a licensed electrician. Unlicensed installation is illegal, will not pass a compliance inspection, and can void your home and contents insurance in the event of a fire.
A licensed electrician will also issue a Certificate of Testing and Compliance upon completion, which is your proof of lawful installation and an important document to retain for insurance and future property sales.
What Happens If You Don’t Comply by 1 January 2027?
Non-compliance carries serious consequences for Brisbane homeowners:
- Your home insurer may refuse to pay out a fire-related claim if your alarms were not compliant at the time of the fire
- You may face fines under Queensland fire safety legislation
- If you sell your home after the deadline, you will be required to disclose and rectify non-compliance before settlement
