⚡ The Quick Answer
From 1 January 2027, every home in Queensland — including owner-occupied houses — must have photoelectric, interconnected smoke alarms in every bedroom, in the hallways connecting them, and on every level. Rentals and homes being sold have needed this since 2022. For a typical North Brisbane home, full compliance is 3–7 alarms and takes 1–2 hours to install. Non-compliance risks fines from $2,757, denied insurance claims, and the inability to sell or lease. Connex Electrical (Lic #92217) installs and certifies compliant alarms across North Brisbane. Call 0474 207 609.
Queensland’s smoke alarm laws have been rolling out in stages since 2017, and 1 January 2027 is the final and biggest deadline. 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 — from North Lakes and Mango Hill to Redcliffe and Caboolture — this guide explains exactly what the deadline means for you, how to tell if your home already complies, what it costs to fix, and what happens if you don’t.
🔑 Key Takeaways
- 1 January 2027 deadline: every Queensland home — including owner-occupied — must have compliant smoke alarms.
- Compliant means: photoelectric, interconnected, in every bedroom + hallway + every level, powered by 240V mains or a sealed 10-year lithium battery.
- Typical North Brisbane home: 3–7 alarms, installed and certified in 1–2 hours.
- Don’t wait: electricians book out fast as the deadline approaches — the December 2026 rush is coming.
- Free assessment: Connex checks your home and gives you a fixed price with no obligation.
What the Law Requires by 1 January 2027
Under the Fire and Emergency Services Act 1990 and the Building Fire Safety Regulation 2008, all Queensland homes must have smoke alarms that are:
- Photoelectric (not ionisation — the old type with a radioactive element)
- In every bedroom
- In hallways connecting bedrooms to the rest of the home
- On every level of the home (including basements and loft areas)
- Interconnected — when one alarm sounds, they all sound
- Either hardwired (240V) or using wireless RF interconnection
- Powered by 240V mains or a 10-year sealed lithium battery
- Compliant with Australian Standard AS 3786:2014
The Compliance Timeline: 2017, 2022 and 2027
Queensland’s rules have been phased in over a decade. Here’s who was affected and when:
| Date | Who It Affects | What Changed |
|---|---|---|
| 1 Jan 2017 | New builds & substantially renovated homes | Must install compliant alarms from day one |
| 1 Jan 2022 | Rental properties & homes being sold or leased | Must be fully compliant before sale or new lease |
| 1 Jan 2027 | ALL homes — including owner-occupied | Every dwelling must be fully compliant. No exemptions. |
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 — but there’s no reason to wait.
Am I Already Compliant? Self-Assessment Checklist
Run through this quick checklist to see whether your North Brisbane home meets the 2027 requirements:
- Are your alarms photoelectric? Check the label on the back. If it says “ionisation” or shows a radioactive symbol, they need replacing.
- Are they interconnected? Press and hold the test button on one alarm. Do all the alarms in the house sound? If not, they’re not interconnected.
- Is there an alarm in every bedroom? Count your bedrooms, count your alarms.
- Is there an alarm in every connecting hallway?
- Is there an alarm on every level? Even levels where nobody sleeps.
- Are they powered correctly? Hardwired 240V or a sealed 10-year lithium battery. Replaceable 9V-battery units are not compliant.
- Are they less than 10 years old? Check the manufacture date printed on the back — alarms expire after 10 years.
Answered “no” to any of these? Your home isn’t compliant yet. The good news is that fixing it is usually a straightforward 1–2 hour job.
What’s Wrong With Your Current Alarms
Most homes across Kallangur, Petrie, Dakabin, and Lawnton built between 1995 and 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 fatal house fires). Must be replaced with photoelectric.
- Battery-only alarms with replaceable 9V batteries — must be replaced with 240V hardwired or 10-year sealed lithium units.
- Not in every bedroom — older rules only required alarms in hallways, not bedrooms.
- Not interconnected — standalone alarms won’t alert you if the fire starts on the other side of the house.
- Expired — smoke alarms have a 10-year lifespan. Check the manufacturing date on the back.
Where Smoke Alarms Must Go (Placement Rules)
Queensland legislation is specific about placement. Compliant alarms must be installed:
- In every bedroom — including guest rooms and any room used for sleeping.
- In every hallway that connects bedrooms to the rest of the home. Where there’s no hallway, an alarm goes between the bedroom and the nearest exit.
- On every level — including ground floors, upper floors, and habitable basements.
Where alarms should NOT go (to avoid false alarms):
- Kitchens (cooking smoke)
- Bathrooms and laundries (steam)
- Garages (exhaust fumes and temperature extremes)
- Within 300mm of a wall, corner, or ceiling fan
- Directly above air conditioning vents
Photoelectric vs Ionisation: Why the Change?
Ionisation alarms respond quickly to fast-flaming fires but are slow to detect smouldering fires — the type that produces heavy smoke before flames appear and is responsible for most fire deaths. Photoelectric alarms detect smouldering fires far earlier, giving your family more time to escape. That’s why Queensland law now requires photoelectric alarms in every home.
Hardwired vs Wireless Interconnection
Both options comply with Queensland law. Here’s the difference:
Hardwired (240V): Connected by electrical cable through the ceiling with battery backup. The most reliable option and standard for new builds, renovations, or when you’re already having electrical work done. Must be installed by a licensed electrician. If your home needs a switchboard upgrade to support hardwired alarms, that’s part of the compliance picture too.
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 — particularly the timber Queenslanders in Stafford and Wavell Heights where opening ceilings isn’t practical.
We install both types. For most existing homes across North Brisbane, wireless interconnected alarms are the most cost-effective route to compliance.

What Happens If You Don’t Comply
Fines
Penalty infringement notices can be issued for non-compliant smoke alarms, with fines currently starting from $2,757 per offence. If a fire causes injury or death and non-compliant alarms contributed, 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.
Advice for Sellers
Selling since 2022 has required compliant smoke alarms before settlement. A buyer can request compliance be confirmed, and a non-compliant home can delay settlement. Get your alarms sorted and certified before you list — it’s cheaper and less stressful than a last-minute scramble.
Advice for Landlords
If you own a rental in North Brisbane, your property should already be compliant — the rental deadline passed on 1 January 2022. Landlords must:
- Audit all rental properties for current smoke alarm compliance
- Replace any ionisation alarms with photoelectric models
- Ensure alarms are installed in every bedroom and connecting hallway
- Ensure all alarms are interconnected
- Keep records of installation dates, testing and maintenance
- Test alarms at every change of tenancy
Connex provides bulk installations for property portfolios. For the full picture, read our landlord electrical safety obligations guide.
Advice for Homeowners
Even though owner-occupied homes have until 2027, upgrading now means your family is protected today. An electrical safety inspection can assess your current alarms and identify exactly what needs to change.

Frequently Asked Questions
Can I install smoke alarms myself?
You can install battery-powered alarms yourself, but hardwired 240V 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.
How much does smoke alarm compliance cost?
For most North Brisbane homes we charge $120 per alarm, and most homes need 4 to 8 alarms, so a typical full compliance job runs $500 to $1,000, including alarms, installation, testing, and a compliance certificate. Larger homes are quoted on inspection.
My smoke alarm keeps beeping — does that mean it’s faulty?
A single chirp every 30–60 seconds usually means a low battery or end-of-life alarm. See our smoke alarm beeping guide for what each pattern means and how to fix it.
What about someone who is deaf or hard of hearing?
Standard alarms won’t reliably wake profoundly deaf or hard-of-hearing occupants. Specialised alarms with bed shakers, strobe lights, or 520Hz low-frequency sound are available — see our smoke alarms for deaf and hard of hearing guide.
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 →
