From 1 January 2027, every Queensland home must have interconnected photoelectric smoke alarms in every bedroom, in hallways that connect bedrooms to the rest of the home, and on every storey. This is the final phase of the state’s smoke alarm laws and it applies to owner occupied homes. Rentals and homes being sold have had to comply since 1 January 2022, and new builds since 2017, so if you own the home you live in and have not sold, leased or substantially renovated it recently, this deadline is yours. Faze Electrical & Airconditioning installs compliant Red Alarm 10 year lithium interconnected photoelectric alarms across Brisbane and Logan for $181.50 each installed, or $726 for a typical four alarm home, under QLD Electrical Contractor Licence 90552.

What changes on 1 January 2027
Queensland’s smoke alarm reforms were legislated in 2016 and rolled out in three phases over ten years, so the 2027 date is not new law, just the last group of homes reaching their deadline.
| Date | Who had to comply |
|---|---|
| 1 January 2017 | New builds and homes undergoing substantial renovation. All new or replacement alarms from this date must be photoelectric and comply with AS 3786-2014. |
| 1 January 2022 | Homes being sold, and rental properties at the start or renewal of a lease. |
| 1 January 2027 | Every other home in Queensland, which in practice means owner occupied houses, townhouses and units. |
The Queensland Fire Department publishes the official guidance on its smoke alarms page, and everything below follows it.
What interconnected photoelectric actually means
Four requirements sit behind the label, and all four must be met:
- Photoelectric sensor. The alarm detects visible smoke particles, which makes it far quicker to react to the smouldering fires that kill people in their sleep. Ionisation alarms, the older cheap type, do not comply when alarms are replaced. Every alarm must meet Australian Standard AS 3786-2014.
- Interconnected. When one alarm triggers, every alarm in the home sounds. A fire in the kitchen at 2:00am wakes someone behind a closed bedroom door at the other end of the house. Interconnection can be wired or wireless.
- Powered properly. Alarms must be hardwired to 240 volts or powered by a non removable 10 year battery. Alarms with a replaceable 9 volt battery do not comply. Importantly, an existing hardwired alarm must be replaced with a hardwired alarm, which is licensed electrician work.
- Less than 10 years old. Smoke alarm sensors degrade, so every alarm carries a manufacture date and must be replaced within 10 years.
Where alarms must go, room by room
The placement rules are the same for every dwelling:
- One alarm in every bedroom
- One alarm in each hallway that connects bedrooms to the rest of the home
- If there is no hallway, one alarm between the bedrooms and the rest of the storey
- At least one alarm on every storey, including storeys without bedrooms, placed in the most likely path of travel out of the building
Position matters too. Alarms go on the ceiling, at least 300 millimetres from a corner or a light fitting and at least 400 millimetres from an air conditioning vent or the blade tip of a ceiling fan, because moving air can delay smoke reaching the sensor. In a typical three bedroom single storey home that works out to four alarms, and a four bedroom double storey home usually needs five or six.
Penalties, settlements and insurance
Three practical consequences follow from not complying, and none of them is worth the savings.
The fine. Failing to meet the smoke alarm requirements carries a maximum penalty of 5 penalty units under the Fire Services Act 1990. A Queensland penalty unit is $172.70 from 1 July 2026, so that is a fine of up to $863.50.
Selling the house. Sellers declare compliance as part of the sale process, and under the standard Queensland contract a buyer who settles on a home without compliant alarms can claim an adjustment of 0.15 percent of the purchase price at settlement. On an $800,000 sale that is $1,200 handed back, which is considerably more than compliant alarms cost to install.
Insurance. Non compliance does not automatically void a home insurance policy, but after a fire an insurer will ask questions, and answering them from a non compliant home adds friction to a claim at the worst possible moment. The stronger argument was never financial anyway: interconnected photoelectric alarms exist because they wake everyone in the house while there is still time to get out.
What it costs to comply
Faze installs Red Alarm interconnected photoelectric smoke alarms with a sealed 10 year lithium battery and wireless interconnection for $181.50 per alarm installed, including GST. A typical four alarm home is $726. Where your existing alarms are hardwired, we replace them with hardwired photoelectric alarms as the law requires, which is exactly the work our electrical contractor licence (90552) covers. Every job starts with a walk through: we test what is already on the ceiling, map what your floor plan actually needs, and quote in writing before anything is installed. Details and booking are on our smoke alarm installation Brisbane page, and our smoke alarm installation cost guide breaks the pricing down further.
Book before the December rush
Every compliance deadline produces the same curve: quiet months, then a December panic when installers are booked out and prices firm up. The work itself is quick, a four alarm home usually takes under two hours, so booking in spring gets it done at normal prices with no waiting. We install across Brisbane and Logan, our office is open Monday to Friday 7:00am to 3:30pm, and if you want an electrician for anything else while we are there, our Logan electricians page covers the rest of what we do.
Frequently asked questions
What are the new smoke alarm laws in Queensland for 2027?
From 1 January 2027 every Queensland home must have photoelectric smoke alarms that comply with AS 3786-2014, are interconnected so they all sound together, are either hardwired or powered by a non removable 10 year battery, and are installed in every bedroom, in hallways that connect bedrooms, and on every storey.
Do owner occupiers really have to comply by 1 January 2027?
Yes. Owner occupied homes are the final phase of a rollout that started in 2017. New builds complied from 1 January 2017 and homes being sold or leased from 1 January 2022, so 1 January 2027 is the date the requirements reach every remaining home in the state.
Can I install interconnected smoke alarms myself?
Battery powered alarms with wireless interconnection can be installed by a homeowner. Anything involving 240 volt wiring must be done by a licensed electrician, and an existing hardwired alarm must be replaced with a hardwired alarm, so most homes built since the 1990s need an electrician for at least part of the job.
How many smoke alarms does my house need?
Count one per bedroom, one for each hallway that connects bedrooms to the rest of the home, and at least one on any storey without bedrooms. A typical three bedroom single storey home needs four alarms, and a four bedroom double storey home usually needs five or six.
What happens if I do not comply by the deadline?
The maximum penalty is 5 penalty units under the Fire Services Act 1990, which is a fine of up to $863.50 at the penalty unit value that applies from 1 July 2026. When you sell, a buyer can claim an adjustment of 0.15 percent of the purchase price at settlement if the alarms are not compliant, and non compliance can also complicate an insurance claim after a fire.
