QLD Smoke Alarm Laws: What Every Homeowner Must Do Before 1 January 2027

By 1 January 2027, Queensland’s smoke alarm rules reach their last group: owner-occupied homes that earlier deadlines didn’t already cover. Those homes need interconnected photoelectric alarms in every bedroom, in the hallways between them, and on every storey.

That distinction matters. Plenty of alarm sellers smudge the stages together to make you panic and buy. So here’s what the law actually says, and where you can check it yourself.

The Stages, Where Your Home Fits

Queensland phased the rules in over several years. Find your situation below.

New builds and major renovations (already in force since 2017) Built or substantially renovated your place after 1 January 2017? It had to comply when the work was done. These homes need hardwired 240V photoelectric alarms, interconnected by wiring.

Homes sold or rented (already in force since 2022)

• A sale contract signed after 31 December 2021 meant the home had to comply.
• For rentals, the rule kicks in at the start of any new or renewed lease from 1 January 2022.

If you sold or leased out a place in the last few years, you’ve already been under these rules.

Owner-occupied homes (1 January 2027) This is the date everyone keeps mentioning. Stage 3. If you live in your own home and the earlier stages didn’t catch it, you’ve got until 1 January 2027 to comply. Worth confirming the detail for your own situation at fire.qld.gov.au.

What “Compliant” Actually Means

There are only a few rules. Miss any one of them and you’re not compliant.

• Photoelectric only. Alarms must meet AS 3786-2014. Ionisation alarms are out. Combination alarms are out too.
• Interconnected. Trip one, they all sound. You get there by wiring (that’s a licensed electrician) or by wireless interconnect.
• Placed correctly. Every bedroom. The hallways linking bedrooms to the rest of the house. Every storey.

One standalone photoelectric alarm in the hallway won’t cut it, even if it’s exactly the right type. They have to talk to each other.

Hardwired vs Wireless Battery, The Honest Answer

This is where the upsell usually starts. Here’s the plain version.

Wireless 10-year battery alarms are legal for existing homes. The battery is sealed and lasts a decade, and the alarms link to each other over wireless. You can fit them yourself. No electrician needed.

Hardwired 240V alarms run off your home’s power circuit, and a licensed electrician has to install them. One catch: if your current alarms are already hardwired, the replacements have to be hardwired too.

So which is better? Depends on the house. Battery wireless saves you the install cost. Hardwired means you never think about a battery again, and new builds have no choice anyway.

PQ Electrical fits hardwired interconnected alarms. But if wireless battery alarms would do the job at your place, we’ll say so.

Selling Your Home

Selling? Compliance is baked into the contract. You declare it on the Form 24 at settlement. Where a licensed electrician installed hardwired alarms, you’ll also need a Certificate of Testing and Compliance, required under s227 of the Electrical Safety Regulation 2013.

Sort it before you list, not the week before settlement. Chasing an electrician with a contract date looming is a bad time to discover your alarms are the wrong type.

Renting Out Your Property

The landlord installs and tests the alarms before each tenancy begins, not the tenant. Once someone’s living there, the tenant tests and cleans them through the lease.

If you’re a landlord and a lease renewed after 1 January 2022 without compliant alarms, that’s already overdue. Worth fixing now.

A Note on Dodgy Sales Tactics

Queensland Fire Department has flagged that some traders misrepresent the law, usually to push owners into buying something they don’t need, or don’t need yet. If a salesperson tells you that you must hardwire right now, as an owner-occupier in an existing home you haven’t recently sold or leased, be sceptical. Check it at fire.qld.gov.au before you sign anything.

We’d rather lose the job than tell you a porky about what the law actually requires.

FAQ

Do I have to use a licensed electrician for smoke alarm compliance?

Only for hardwired alarms. Wireless 10-year battery photoelectric alarms can be self-installed in an existing home. Once a home has hardwired alarms, though, every future replacement has to be hardwired too.

Can I keep my existing alarms if they’re already hardwired?

Only if they’re photoelectric and meet AS 3786-2014. Older hardwired ionisation alarms don’t make the grade and have to go. Same with combination alarms, they’re not permitted.

What if I don’t comply before the deadline?

Non-compliance can block you from selling or renting, and it can complicate things after a fire. The exact penalties and how your cover responds are best checked directly with Queensland Fire Department and your insurer.
