The law, plainly
Queensland smoke alarm laws and the 1 January 2027 deadline
Three phases, one of which is almost certainly yours. What the law actually requires, where the alarms have to go, and the age limit nobody mentions.
Three deadlines, not one
Queensland did not switch the rules on in a single day. The reforms came in three phases, and which one caught your house decides whether you have work to do.
| From | Applies to |
|---|---|
| 1 Jan 2017 | New homes, and existing homes undergoing substantial renovation |
| 1 Jan 2022 | Any home when it is sold or leased |
| 1 Jan 2027 | Every remaining home in Queensland — including the one you live in |
If nothing has triggered the earlier phases — you have not sold, you have not leased it out, and you have not done a major renovation since 2017 — then 1 January 2027 is your date, and it applies to the house you sleep in.
What "compliant" actually means
Five things have to be true. Most houses fail on the fourth.
- Photoelectric, compliant with Australian Standard AS 3786:2014
- No ionisation sensor — the older type is no longer acceptable
- Less than 10 years old, which is why a compliant install still expires
- Interconnected, so when one sounds every alarm in the house sounds
- Either hardwired to 240V with a backup, or powered by a sealed 10-year battery
Interconnection is the requirement that catches nearly everyone. A house can have five perfectly good photoelectric alarms and still be non-compliant, because each one only sounds for itself. A fire starting in the lounge at 2am has to wake someone at the far end of the house — that is the entire point of the rule.
Where they have to go
- In every bedroom
- In hallways that connect bedrooms to the rest of the house
- Between the bedrooms and the rest of the house where there is no hallway
- On every storey, including storeys with no bedrooms — positioned on the likely path out
Not in kitchens. Cooking fumes set photoelectric alarms off, and an alarm people disable because it nuisance-trips is worse than no alarm at all.
The ten-year clock nobody mentions
A compliant alarm must be less than ten years old. That has an awkward consequence: a house built in 2017, which met the brand-new interconnection rule at the time, has alarms reaching the end of their legal life right about now. Complying once is not the same as complying forever.
The manufacture or expiry date is printed on the body of the alarm, usually on the back or around the rim. If you can get to yours, it is worth a look before you spend anything.
Which phase are you in?
Built or substantially renovated since 2017
Probably compliant — but check the age. Interconnected photoelectric alarms were required at build. Confirm they are interconnected and still inside the ten years.
Sold or newly leased since January 2022
Should already be done. Compliance was required at that point. If it was skipped, you are non-compliant now, not in 2027.
Anything else
You have until 1 January 2027. Most Queensland homes are here. The work is a few hours and does not need rewiring.
Hardwired or battery?
Both are legal. Sealed ten-year lithium alarms with wireless interconnection need no cabling, no holes cut in your ceilings and no electrician, which makes them the straightforward choice for a house that is not already wired for it.
If your place already has 240V hardwired alarms that need replacing, that is licensed electrical work. I bring in the electrician I work with and it comes back as one quote with his work as its own line item — see what it costs.
Questions people ask
Do you need a smoke alarm compliance certificate in Queensland?
No. There is no government smoke alarm certificate in Queensland, and the Queensland Fire Department neither issues nor requires one for a home. What the law asks for depends on why the work is being done. If you are selling, you declare on the Property Information (Transfer) form that the home complies. If you are renting the place out, you must test and clean every alarm within 30 days before a tenancy starts. I leave a dated record either way — every alarm's make, model and expiry date, a photo of each one in place, and the result of the interconnection test — so you can evidence what was done and when.
What are the new smoke alarm requirements in Queensland?
Every alarm in the home must comply with Australian Standard AS 3786-2014, which is printed on the body of the alarm. It must be photoelectric and must not contain an ionisation sensor. It must be interconnected with every other alarm in the dwelling, so that when one sounds they all sound. And it must be either hardwired by a licensed electrician with a secondary power source, or powered by a ten-year non-removable battery. From 1 January 2027 that applies to every existing home in Queensland — not only rentals and houses being sold.
Do I need to upgrade the smoke alarms before selling my house in Queensland?
Yes, and this has been the case for a few years already. For any contract of sale signed after 31 December 2021 the seller must bring the dwelling up to standard before transfer, and declare on the Property Information (Transfer) form that it has been done. If you are thinking about listing, it is a far cheaper job now than it is in the middle of a settlement.
Where do smoke alarms have to go in a Queensland house?
On each storey, in every bedroom, and in the hallways that connect the bedrooms to the rest of the dwelling. Where there is no hallway, one goes between the bedrooms and the other parts of that storey. Where a storey has no bedrooms on it at all, at least one alarm goes in the most likely path of travel out of the house. This is the part people get wrong fitting their own — a six-pack from the hardware store does not help much if two of them end up in the wrong rooms.
How much does smoke alarm compliance cost?
$440 for a standard three-bedroom home, up to four alarms supplied, installed and tested in the one visit. $65 for each extra alarm after that. It is a flat price, not an hourly rate, and it covers the alarms themselves. Replacing 240V hardwired alarms is licensed electrical work and is quoted separately, with the electrician's work as its own line on the one quote from me.
