Your home needs interconnected photoelectric alarms by 1 January 2027.
- Applies to existing private homes, townhouses, units and manufactured homes.
- You do not need to notify the Queensland Fire Department that you have complied.
Queensland · 1 January 2027
All alarms
sound
together

From 1 January 2027, all existing private homes, townhouses, units and manufactured homes in Queensland need interconnected photoelectric smoke alarms. We look at what is already on your ceilings, tell you what the dwelling needs, and fit it, usually in a single visit.
There is no notification step once it is done. If you are selling or letting the property, the upgrade is already required: sellers declare it on the transfer form, and landlords test and clean every alarm before each tenancy.

From 1 January 2027 the requirement covers all existing private homes, townhouses, units and manufactured homes.
Required alarms must be photoelectric. An alarm containing an ionisation sensor does not comply.
Every alarm must be interconnected with every other alarm in the home, so that when one activates they all activate.
The alarm must comply with Australian Standard 3786-2014. The marking is on the body, you may need to lift it off the bracket to read it.
Either hardwired to mains with a secondary power source, or powered by a non-removable 10-year battery.
Every alarm must be interconnected with every other alarm in the home, so that when one activates they all activate.

The
visit
We start with what is already on your ceilings, whether it is photoelectric, and whether the body carries the AS 3786-2014 marking, then confirm what the dwelling needs. A home with mains-powered alarms keeps mains power; a home with battery alarms can move to sealed 10-year battery alarms.
Book a timeWhat you are left with
Every required alarm in place
On each storey, in each bedroom, and in the hallways that connect them.
All of them interconnected
Linked so that when any one detects smoke, every alarm in the dwelling sounds.
Every alarm tested
Each one sounded on the day, and the whole set checked together rather than one at a time.
The paperwork
Hardwired work carries a Certificate of testing and compliance under s227 of the Electrical Safety Regulation 2013.
Queensland decides the answer, not us. Set the shape of the dwelling and the alarms appear where the rules put them.
Indicative requirement

An estimate from the placement rules, not a quote. Real homes have odd corners, we confirm on site.
Where they go, 3 bedrooms, 1 storey
Every one interconnected, so all of them sound together.
Interconnection is the whole point: when one alarm detects smoke, every alarm in the dwelling sounds. This is where they have to go.
Book an assessmentEvery level of the dwelling needs coverage.
Every room used for sleeping.
Hallways that connect the bedrooms to the rest of the dwelling.
Between the bedroom and the other parts of that storey.
At least one alarm in the most likely path of travel out of the dwelling.
The 2027 requirement is the same for every dwelling. What changes is who arranges the upgrade, and what you need to be able to show.

Somewhere else on the Sunshine Coast? Ask, it is usually a yes.

The AS 3786-2014 marking is on the body of the alarm, not the cover. You may need to lift it off its bracket to read it.
All existing private homes, townhouses, units and manufactured homes must have interconnected photoelectric smoke alarms by 1 January 2027. If you are selling, renting or re-renting a home, they must already be installed.
Every required alarm is linked to every other one, so when any single alarm detects smoke, all of them sound, not just the one in that room.
Yes. Alarms are required in each bedroom, on each storey, and in the hallways that connect bedrooms to the rest of the home.
If your home has battery alarms now, yes: photoelectric alarms powered by a non-removable 10-year battery comply. If it already has 240-volt alarms, their replacements must also be 240-volt, and new homes and major renovations need hardwired alarms.
Check the body of the alarm for the AS 3786-2014 marking, and check that it is photoelectric rather than ionisation. You may need to lift it off its bracket to read the marking.
No. There is no notification step. When selling a home you may need to provide proof that you have complied.
Every requirement on this page is transcribed from Queensland Fire Department, Smoke alarms and Queensland Government, Smoke alarms, checked on 15 September 2026. It is general information about the Queensland requirements, not advice about your particular dwelling.
Tell us the suburb and roughly what the dwelling is. We confirm what it needs and what the visit involves before anything is booked.
