Queensland’s smoke alarm laws changed in 2017 — and the final compliance deadline is 1 January 2027. After that date, every Queensland home must have interconnected photoelectric smoke alarms installed in every bedroom, hallway, and on every level. No exceptions.
If you own or rent a property in North Brisbane, here’s exactly what the deadline means for you — and what happens if you don’t comply.
What the Law Requires by 1 January 2027
Under the Fire and Emergency Services Act 1990, all Queensland homes must have:
- Photoelectric smoke alarms (not ionisation — the old type with a radioactive element)
- In every bedroom
- In hallways connecting bedrooms
- On every level of the home (including basements and loft areas)
- Interconnected — when one alarm sounds, they all sound
- Either hardwired or using wireless interconnection
- Powered by 240V mains or a 10-year sealed lithium battery
Who Needs to Comply and When
- Already required (since 2022): all homes being sold or leased, substantially renovated homes, and new builds
- By 1 January 2027: ALL remaining owner-occupied homes — this is the final deadline
If you’ve sold or leased a property since 2022, you should already be compliant. If you’re an owner-occupier who hasn’t upgraded, you have until 1 January 2027.
What Happens If You Don’t Comply
Fines
Penalty infringement notices can be issued for non-compliant smoke alarms. Fines currently start from $2,757 per offence. If a fire occurs and non-compliant alarms contributed to injury or death, criminal charges can follow.
Insurance Problems
Most home insurance policies require working smoke alarms that meet current regulations. Non-compliant alarms could give your insurer grounds to reduce or deny a claim. We see this risk constantly across North Lakes, Mango Hill, and Griffin — homes with expired ionisation alarms that haven’t been touched since the builder installed them.
Can’t Sell or Rent
Non-compliant homes cannot legally settle a sale or commence a new tenancy. If you’re selling a property in Redcliffe, Caboolture, or anywhere in Queensland, compliant smoke alarms must be in place before settlement.
What’s Wrong With Your Current Alarms
Most homes across Kallangur, Petrie, Dakabin, and Lawnton built between 1995-2015 have one or more of these problems:
- Ionisation alarms — the old type that’s slow to detect smouldering fires (the most common type in house fires). These must be replaced with photoelectric.
- Battery-only alarms with replaceable 9V batteries — these need replacing with 240V hardwired or 10-year sealed lithium
- Not in every bedroom — older rules only required alarms in hallways, not bedrooms
- Not interconnected — standalone alarms don’t alert you if the fire is on the other side of the house
- Expired — smoke alarms have a 10-year lifespan. Check the manufacturing date on the back.
Hardwired vs Wireless Interconnection
Both comply with Queensland law. Here’s the difference:
Hardwired (240V): Connected by electrical cable through the ceiling. Most reliable. Best for new builds, renovations, or when you’re already having electrical work done. Requires a licensed electrician.
Wireless interconnection (RF): 10-year sealed lithium battery alarms that communicate via radio frequency. No cabling required. Ideal for existing homes where running cable would be disruptive or expensive — particularly the timber Queenslanders in Stafford and Wavell Heights where opening walls isn’t practical.
We install both types. For most existing homes in North Brisbane, wireless interconnected alarms are the most cost-effective solution.

Frequently Asked Questions
Can I install smoke alarms myself?
You can install battery-powered alarms yourself, but hardwired alarms must be installed by a licensed electrician. Regardless of type, the alarms must meet the interconnection and placement requirements to be compliant.
How do I know if my alarms are ionisation or photoelectric?
Check the back of the alarm for labelling. Ionisation alarms are often marked with an “I” or the word “ionisation.” Photoelectric alarms are marked with a “P” or “photoelectric.” If the alarm is over 10 years old, it needs replacing regardless of type.
Do I need alarms in the kitchen or bathroom?
No — the legislation specifically excludes kitchens, bathrooms, and garages due to false alarm risks from cooking steam and exhaust. Alarms are required in bedrooms, hallways connecting bedrooms, and on each level.
What about rental properties?
Landlords are responsible for installing compliant smoke alarms. Tenants are responsible for testing and replacing batteries (for non-sealed units), and for not tampering with or removing alarms. Read our landlord obligations guide →
