Is your home ready? Queensland's new smoke alarm laws take effect January 2027

With less than seven months to go, Queensland homeowners face a critical deadline — and time to book a compliant upgrade is running out fast.

Queensland has some of the most comprehensive smoke alarm laws in Australia, and the final stage of those laws is almost here. From 1 January 2027, all existing private homes, townhouses, and units must have interconnected photoelectric smoke alarms installed — no exceptions.

If you own and live in your home, this deadline applies to you. Here's everything you need to know.

How did we get here?

Queensland's smoke alarm reform has been a staged rollout introduced in 2017, driven by coronial findings following a series of preventable house fire fatalities.

2017 — The starting point

New builds and major renovations required photoelectric, interconnected alarms. Old alarms over 10 years old had to be replaced.

2022 — Rentals and properties for sale

Rental properties and homes being sold became subject to the full new requirements. Landlords became responsible for installation; properties sold required a compliant Form 24 lodged with the Queensland Land Registry.

1 January 2027 — All remaining homes

Every remaining owner-occupied home in Queensland must comply. There is no grace period after this date.

What exactly is required?

The legislation is specific. Your smoke alarms must:

Photoelectric type only

Compliant with Australian Standard AS3786-2014. Ionisation alarms are no longer permitted.

Interconnected

When one alarm activates, every alarm in the home must sound simultaneously.

Hardwired or 10-year battery

Must be mains-powered or fitted with a non-removable 10-year battery. Standard 9V batteries are not permitted.

Alarms must be installed in these locations:

• In each bedroom

• In hallways that connect bedrooms to the rest of the home

• On every storey of the home

• If there is no hallway, between the bedrooms and other areas of the home

• If there are no bedrooms on a storey, at least one alarm in the most likely exit path

Why photoelectric alarms?

Older ionisation alarms are slow to detect smouldering fires — the most common type in residential homes, and the most dangerous because they tend to spread while families sleep. Photoelectric alarms detect smoke particles earlier and more reliably, responding within minutes. They also produce far fewer false alarms, making them a clear upgrade in both safety and practicality.

What about caravans and motorhomes?

From 1 January 2027, all Queensland-registered caravans and motorhomes must also have a photoelectric smoke alarm fitted to the ceiling. (Note: if your caravan's registration commenced or was transferred after 1 July 2024, this already applies to you.)

Don't leave it too late

Demand will spike in late 2026

Every licensed electrician in Queensland will be heavily booked in the final months before the deadline. Waiting too long risks missing the cut-off entirely — and non-compliance is not a minor oversight. Property owners who fail to comply can receive infringement notices from the Queensland Fire Department.

Quick checklist for homeowners

• Identify the type of alarms you currently have — are they photoelectric? Check the date stamped on the back. Alarms more than 10 years old must be replaced regardless.

• Confirm all alarms are interconnected — when you test one, do all others activate?

• Check alarm placement — every bedroom, every hallway connecting bedrooms, and every storey must be covered.

• If replacing a hardwired alarm, it must be replaced with another hardwired alarm — you cannot swap to battery-only.

• Book a licensed electrician sooner rather than later — availability is already tightening across Queensland.
