The short version

  • Every Queensland dwelling must eventually have interconnected photoelectric smoke alarms compliant with Australian Standard 3786:2014: every bedroom, connecting hallways, and every storey.
  • Rentals and homes being sold have met this standard since 1 January 2022.
  • Every other home must comply by 1 January 2027.
  • Rental alarms must be tested and cleaned within 30 days before every tenancy starts or renews, and at least every 12 months.
  • Every alarm must be replaced before it turns 10 years old, from its manufacture date.
  • Ionisation and standalone (non-interconnected) alarms don't meet the standard.

Where the rules come from

Queensland's smoke alarm requirements live primarily in the Fire and Emergency Services Act 1990, as amended by the Fire and Emergency Services (Domestic Smoke Alarms) Amendment Act 2016, passed after the 2011 Slacks Creek house fire, Australia's deadliest domestic house fire. Landlord and tenant obligations sit in the Residential Tenancies and Rooming Accommodation Act 2008. The technical standard alarms must meet is Australian Standard 3786:2014.

The three-stage timeline

Queensland smoke alarm legislation timeline
From Who must comply
1 Jan 2017 New builds and substantially renovated dwellings (compliance triggered at building approval)
1 Jan 2022 All rental properties (at tenancy start or renewal) and all dwellings being sold (at contract transfer)
1 Jan 2027 Every dwelling in Queensland, including owner-occupied homes that haven't sold or been renovated

What a compliant installation looks like

  • Type: photoelectric only, compliant with AS 3786:2014. Ionisation alarms don't qualify; photoelectric alarms detect slow, smouldering fires, the kind that kill people asleep, far earlier.
  • Interconnection: every alarm must trigger together, so one room's alarm wakes the whole house. Wired or wireless both qualify.
  • Placement: every bedroom, hallways connecting bedrooms to the rest of the home (or between bedrooms and exits with no hallway), and at least one per storey.
  • Power: hardwired to 240V, or a non-removable 10-year lithium battery. Removable 9V batteries don't meet the standard for new installations.
  • Age: replaced before 10 years from the manufacture date, not the installation date.

Rental properties: who does what

The property owner / landlord must:

  • Test and clean every alarm within 30 days before each tenancy starts or renews
  • Test and clean alarms at least once every 12 months during a tenancy
  • Replace flat or nearly flat batteries, and replace any alarm that fails testing
  • Replace every alarm before its 10-year manufacture-date anniversary

The tenant must:

  • Not remove, tamper with or paint over alarms
  • Report any alarm failure or fault to the owner or property manager
  • Allow reasonable access for testing and maintenance

"Testing" has a specific meaning: pressing the test button and confirming the alarm sounds. A visual glance doesn't satisfy the obligation, which is why written records of each test matter: they're the evidence it was actually met.

Selling a property

Since 1 January 2022, every dwelling sold in Queensland must have compliant interconnected photoelectric alarms at contract transfer. The seller declares compliance in the contract, and buyers' solicitors routinely require evidence, so arrange the upgrade and certification before listing: leaving it until between contract and settlement is the most common, most stressful mistake we see. See our full guide to selling a house in QLD.

Penalties and liability

Non-compliance can attract fines under the Fire and Emergency Services Act, and for rentals it can breach the tenancy agreement. The larger exposure is civil and insurance liability: if a fire occurs in a non-compliant property, owners face potential claims and insurers may dispute payouts. Compliance certificates and written test records are the paper trail that protects you.
