If you are selling a Queensland home, or advising a seller, smoke alarm compliance is not a background detail. Under the Property Law Act 2023, seller disclosure matters are addressed through the Form 2 seller disclosure statement and the other sale preparation steps. Queensland law sets specific smoke alarm requirements Queensland sellers must meet, and guidance from Queensland Government smoke alarm guidance and the Queensland Fire Department smoke alarm fact sheet explains what compliant alarms look like. Other states and territories have different rules.
This guide walks through what Queensland law requires when a home is sold, what a compliant setup looks like, which alarms should be replaced before sale, the phased rollout and the 1 January 2027 compliance date, how compliance sits with the sale contract, and what happens if the home is not compliant at sale. It also separates the seller's position from landlord rules, answers common seller questions, covers who this guidance applies to, the sources used, and what to do before you sign. You can review the seller disclosure side through our seller disclosure page. This is general information, not legal advice.
What Queensland law requires when a home is sold
Queensland Government guidance states that all homes being sold or leased must have interconnected photoelectric smoke alarms complying with AS 3786:2014, the Australian Standard the alarms must meet. The requirement attaches to the dwelling at the point of sale.
Alarms must be in every bedroom, in hallways connecting bedrooms, and on each level of the home. According to Queensland Government guidance on selling smoke alarms, it is the homeowner's responsibility to make the home compliant.
Where the installation involves electrical work, such as hardwired alarms, a licensed electrician must install them. Check the current wording on qld.gov.au on the day you act.
Owners who also rent out the property handle separate tenancy rules as part of their property management responsibilities.
For a seller, the question is not whether a deadline is coming but whether the alarms already installed meet the standard.
What a compliant smoke alarm setup looks like
A compliant setup comes down to three attributes: the type of alarm, how the alarms are linked, and where they sit.
Photoelectric alarms use a light sensor to detect smoke. The Queensland Fire Department fact sheet describes this as the type the standard requires, so a unit relying on an ionisation sensor does not meet it.
Interconnected alarms all sound when one is triggered. A fire in one room sets off the alarms in the others.
A compliant unit should carry the AS 3786:2014 code, which is how you can identify one. On placement, alarms are needed on every storey of the home and on the ceiling of registered caravans and motorhomes.
Installation follows two routes. Wireless units have a non-removable 10-year battery and can be installed by the owner. Hardwired units must be replaced with hardwired units, and that work needs a licensed electrician.
These checks sit alongside the other items involved in preparing a home for inspection.
Alarms that should be replaced before a sale
Not every alarm in a Queensland home needs replacing before sale, but several categories do. Under current guidance, units containing an ionisation sensor should be replaced, because the required type is photoelectric. Interconnection is part of the requirement rather than an optional upgrade, so an alarm that is not interconnected should also be reviewed. The Queensland Fire Department fact sheet adds alarms more than 10 years old to that list. Keep that figure separate from the non-removable 10-year battery in wireless units, which describes battery life, not the age at which an alarm should be replaced.
Hardwired alarms must be replaced with hardwired alarms, and every replacement must be photoelectric and comply with AS 3786:2014.
For a seller, the task is practical. Establish what is currently installed, compare it against the required type, interconnection and location, then arrange replacement only where a unit falls short.
The rollout dates and the 1 January 2027 compliance date
Queensland's smoke alarm rules sit within a phased rollout. Under Queensland Government guidance, all existing private homes, townhouses, units and manufactured homes must have interconnected photoelectric alarms by 1 January 2027. The Queensland Fire Department fact sheet gives the same date.
Homes being sold or leased have been inside the requirement since 1 January 2022, so treat the position as settled: if you are selling now, compliant alarms are already required. The 2027 date is the point at which the requirement reaches every Queensland dwelling. It is a backstop for the state, not a trigger for an individual sale.
Check qld.gov.au and fire.qld.gov.au on the day you act in case the dates have moved.
Agents and conveyancers working through Queensland's disclosure scheme apply the same timeline to smoke alarms.
How smoke alarm compliance sits with the sale contract
Queensland Government guidance groups smoke alarms under homes being sold or leased, so the obligation attaches to the dwelling being sold and sits with the homeowner. Queensland Government guidance does not state exactly how smoke alarm compliance is communicated to the buyer in a sales contract; check the current page, or ask your solicitor or conveyancer about your own contract. Smoke alarm compliance is separate from the seller disclosure process, which is covered elsewhere.
Smoke alarm compliance is addressed as part of preparing the home for sale, and a seller's disclosure obligations are dealt with before the buyer signs the contract of sale. The undisclosed issues after settlement process is a separate question. For the wording of your particular contract, speak with your own conveyancer or solicitor. This is general information, not legal advice.
What happens if the home is not compliant at sale
Queensland Government guidance does not state the precise consequence of selling a non-compliant home; check the current position on qld.gov.au and the Queensland Fire Department before relying on any claim about penalties, delays or buyer rights.
What the guidance does say is narrower: a home being sold must have alarms meeting the standard, and it is the homeowner's responsibility to make the home compliant. Because that obligation sits with the seller, a non-compliant setup is an outstanding task, so checking and remediating before the contract stage is the sensible order of work.
If a consequence matters to your sale, take it from the current government page or your legal adviser.
Alarms are a physical feature of the property, so type, location and interconnection can be seen at inspection. Treat the check as preparing the home for sale, not as paperwork.
Selling compared with renting: why the landlord rules are separate
qld.gov.au places homes being sold and homes being leased on the same page, which can make one rule look as though it applies identically to both. A landlord's smoke alarm obligations sit inside the tenancy framework instead, and are set out in the Residential Tenancies Authority's smoke alarm guidance. This article is a seller's guide. If you rent out a property, or you are doing both, use the RTA material for the tenancy side and this guide for the sale side. No tenancy-specific requirements, such as tenancy condition reporting, are applied here. Sellers handling a property that already has tenants can read selling a tenanted property for that side of the transaction.
Who this guidance applies to, and where it differs
The Queensland rules covered above come from qld.gov.au and the Queensland Fire Department. Other Australian states and territories set their own smoke alarm requirements, so a Queensland rule does not automatically apply elsewhere.
This guidance is written for individual sellers, for real estate agents and agencies preparing a listing for sale, and for law firms and conveyancing teams acting for a seller. The smoke alarm check sits alongside the other pre-listing items our Queensland property compliance checklist covers.
It is general information only, not legal advice. Confirm the current requirement on qld.gov.au and fire.qld.gov.au before acting. No prices are quoted, no installers are recommended and no alarm products are picked. The sources set the standard, and a licensed electrician handles the specifics of installation.
Where smoke alarm compliance fits in a seller's preparation
A Queensland sale is a set of compliance items the seller closes out before the contract stage. Smoke alarm compliance is one of them. It attaches to the home being sold and sits with the homeowner, so it runs alongside your disclosure work rather than after it.
Seller disclosure is its own workstream. SearchX prepares compliant seller disclosure statements for Queensland properties, with agents able to order disclosures and handle multiple listings through one platform.
The questions sellers ask most often follow.
Common questions Queensland sellers ask
Does it need to work, or just be installed?
The rule covers type, interconnection and placement. An old or wrong type unit can sound when tested and still not comply. Replacements must be photoelectric and carry the AS 3786:2014 code.
What about existing hardwired alarms?
Hardwired units must be replaced with hardwired units, and the work needs a licensed electrician. Interconnection with existing or mixed hardwired systems is not addressed on the pages reviewed; check the Queensland Fire Department pages on the day.
Can the owner install them?
Wireless units with a non-removable 10-year battery can be installed by the owner, per the Queensland Fire Department fact sheet. Electrical work needs a licensed electrician.
Is there one date?
1 January 2027 is when all Queensland homes must comply. Homes being sold or leased have been inside the requirement since 1 January 2022.
Who is responsible?
qld.gov.au states the homeowner is responsible for making the home compliant.
Sources and verification note
The answers above rest on two government sources. The primary sources are the Queensland Government guidance on smoke alarms for homes being sold or leased at qld.gov.au, and the Queensland Fire Department smoke alarm fact sheet at fire.qld.gov.au. The Residential Tenancies Authority smoke alarm page is the source for the single landlord paragraph, and no other sources are relied on.
Every requirement and date in this article was checked against qld.gov.au and fire.qld.gov.au on the day of writing.
Two points are not stated in the pages reviewed: how compliance is communicated to the buyer in the sales contract, and the consequence of selling a non-compliant home. Both are flagged in their sections, so check the current pages or ask your solicitor.
What to do before you sign
Work through the order of tasks. Confirm what is installed against the required type, interconnection and location, and close out any gap before the contract stage. Confirm the position on the day you act against qld.gov.au and the Queensland Fire Department. If a hardwired replacement is needed, plan for a licensed electrician, as that work cannot be done by the owner. This is general information only, not legal advice.
Conclusion
As you prepare your Form 2 seller disclosure statement under the Property Law Act 2023, remember that the alarm check is a pre-contract task: confirm what is installed, replace only what falls short, and use a licensed electrician for hardwired work. Confirm the position on the day you act against qld.gov.au and the Queensland Fire Department. If contract wording or non-compliance consequences affect your sale, ask your legal adviser, because this is general information only.
