QLD Smoke Alarm Laws 2027: What Every Homeowner Needs to Know

From 1 January 2027, every Queensland home must have photoelectric smoke alarms that meet AS 3786-2014, interconnected so they all sound together, in every bedroom, in hallways connecting bedrooms to the rest of the home, and on every level. Existing 240V alarms must be replaced with 240V alarms by a licensed electrician.

What a compliant home looks like

  • Photoelectric alarms that comply with AS 3786-2014.
  • Interconnected, so when one alarm sounds, every alarm sounds.
  • In every bedroom.
  • In hallways that connect bedrooms to the rest of the home.
  • On every level, even if a level has no bedrooms.
  • No alarm older than 10 years, and every alarm passes a test.

Hardwired vs battery alarms

The power type carries over. If your home has 240V hardwired alarms, they must be replaced with 240V photoelectric alarms, and a licensed electrician must connect them. If your home has battery alarms, you can replace them with photoelectric alarms that have a 10-year non-removable battery. New builds and major renovations need hardwired 240V alarms.

Rentals: landlord and tenant responsibilities

The landlord is responsible for installing compliant alarms and must test each alarm within 30 days before a tenancy starts, including renewals and extensions. Tenants must test and clean each alarm at least once every 12 months.

Rental smoke alarm compliance

Selling a home

Homes being sold must comply before settlement. A certificate of compliance isn't a legal requirement, but agents often ask for one. Hardwired alarms installed by a licensed electrician come with a Certificate of Testing and Compliance.
