Queensland requires photoelectric smoke alarms, interconnected so that one sounding sets off the rest, compliant with Australian Standard 3786-2014, in every bedroom, in hallways connecting bedrooms, and on every storey. All remaining private homes, townhouses and units must comply by 1 January 2027. Leased and sold properties were brought in earlier.

If you already rent the property out, this is not news
Almost every page written about the 1 January 2027 deadline is aimed at owner-occupiers, and it treats interconnected alarms as a change that is coming.
For a Queensland rental, it is not coming. The rollout reached leased and sold properties years before it reaches everyone else, so a compliant rental already has photoelectric alarms, interconnected, in the right rooms.
The deadline that matters to this audience is on a different property: the home you live in, or the one sitting empty, that you might let out later.
Because the moment you convert a home into a rental, you are inside the requirement regardless of the calendar.
Converting a home into a rental is its own trigger
The Queensland Government's wording on the 2017 legislation is worth reading closely, because it names three separate triggers for replacing existing alarms with interconnected ones.
Their sentence: the legislation requires pre-existing smoke alarms to be replaced with interconnected smoke alarms if the smoke alarm has expired, does not work anymore, and/or converting the home into a rental property.
That last clause is the one nobody expects. Deciding to let a house is itself the event. Not the tenancy start, not the lease signing, not a council inspection. The change of use.
So an owner moving out of a home built before the standard, keeping the old alarms because they still beep when tested, has an obligation the day they decide to rent it rather than sell it.
We see this most often on a former family home going into the rent roll for the first time. It is also the cheapest compliance item on the list, which makes it a poor thing to be caught out by.
What the alarms actually have to be
Three requirements, and they stack.
Photoelectric. This is the type that responds better to smouldering fires, which are the ones that kill people in their sleep. Ionisation alarms are not compliant on their own.
Interconnected. When one alarm sounds, they all sound. That is the whole point of the reform: an alarm going off in a laundry at the far end of a house wakes nobody.
Compliant with Australian Standard 3786-2014, which the 2017 legislation set.
On power, either hardwired or fitted with a non-removable ten-year battery. Both are allowed, which matters because hardwiring an older house is a much bigger job than replacing units.
The dates, in the order they arrive
Queensland phased this over a decade rather than all at once, which is why the answer to "is my property compliant" depends on what kind of property it is.
Read the table as three groups rather than three dates. The last group is everyone who has not already been caught by one of the first two.
| From | Who it applies to | What is required |
|---|---|---|
| 1 January 2017 | All dwellings, on replacement | New and replacement alarms must meet AS 3786-2014. Existing alarms must be replaced with interconnected ones once they expire, stop working, or the home is converted to a rental |
| 1 January 2022 | Properties leased or sold | Interconnected photoelectric alarms throughout, as part of the staged rollout |
| 1 January 2027 | All remaining private homes, townhouses and units | Interconnected photoelectric alarms, whether or not the property is ever sold or let |

Where they go
In every bedroom. Not one covering several, one in each.
In hallways connecting bedrooms to the rest of the dwelling, and where there is no hallway, in the space between the bedrooms and the rest of the storey.
On every storey, including a storey with no bedroom on it at all. A single-alarm two-storey house is not compliant however good the alarm is.
The count surprises people. A four-bedroom two-storey house is usually six or seven alarms rather than the two that were there before, and all of them talking to each other.
That is also why interconnection is what pushes owners toward ten-year battery units rather than hardwiring: the wiring run, not the alarm, is the cost.
Caravans and motorhomes, which almost nothing mentions
One line from the Queensland Government that is easy to miss: all registered caravans and motorhomes must also be fitted with a photoelectric smoke alarm.
It is here because a surprising number of investment property owners also own one, and because nothing else on this SERP says it.
The requirement is a photoelectric alarm rather than the full interconnected set, which makes sense in a vehicle.
Nothing FAA does touches this. It is included because it is true, published, and almost never repeated.
Who installs them, and what a manager does about it
A ten-year battery alarm can be fitted by the owner. A hardwired alarm is electrical work and needs a licensed electrician.
That distinction is why most owners converting a property to a rental end up on the battery path: it is compliant, it is quicker, and it does not need a trade.
There is also a service industry built around this, offering annual testing and compliance certificates. Whether that is worth it depends on how many properties you own and how far away you live from them.
For the properties we manage, smoke alarm compliance is part of the work rather than an extra. What we will not do is tell you a property is compliant when we have not checked, or issue anything that looks like a certificate, because we are not an alarm testing service and do not hold ourselves out as one.
If you are converting a home to a rental, the useful order is: check what is fitted, replace before you advertise, and keep the receipt with the tenancy file.
Common questions
No. Queensland accepts either hardwired alarms or alarms with a non-removable ten-year battery, provided they are photoelectric, interconnected and compliant with Australian Standard 3786-2014. That choice matters in an older house, where running new wiring is a far bigger job than fitting battery units. The interconnection requirement is what drives most owners to the ten-year battery option, because wireless interconnection avoids the wiring run entirely.
A rental has to have photoelectric, interconnected alarms compliant with AS 3786-2014, in every bedroom, in hallways connecting bedrooms to the rest of the dwelling, and on every storey. Leased properties were brought into the interconnected requirement well before the general 1 January 2027 deadline, so a compliant rental already meets what the rest of Queensland has until 2027 to do. Converting a home into a rental is itself a trigger to replace pre-existing alarms.
All remaining existing private homes, townhouses and units must have interconnected photoelectric smoke alarms, whether or not the property is ever sold or leased. It is the final phase of a rollout that already covered new work from 2017 and leased and sold properties from 2022. If you own a home you have never let and never sold, this is the date it reaches you.
One in every bedroom, one in each hallway connecting bedrooms to the rest of the dwelling, and at least one on every storey including any storey without a bedroom. In practice a four-bedroom two-storey house is commonly six or seven alarms, all interconnected, against the two that were often fitted before the reform. Counting the rooms before you buy the units avoids a second trip.
Yes. The Queensland Government states that all registered caravans and motorhomes must be fitted with a photoelectric smoke alarm. It is a single photoelectric alarm rather than the interconnected set required in a dwelling. This is included here because it is published and almost never repeated elsewhere; it is not something FAA is involved in.
An alarm with a non-removable ten-year battery can be fitted by the owner. A hardwired alarm is electrical work and requires a licensed electrician. There are also commercial services offering annual testing and compliance reporting, which tend to make sense for owners with several properties or who live away from them. FAA is not an alarm testing service and does not issue compliance certificates.

The 2022 phase is described as part of the staged rollout: the Queensland Fire Department's page renders client-side and could not be quoted directly, so check fire.qld.gov.au for the primary wording.
