Selling a home

When does the obligation start?

The seller’s obligation is triggered by the date the initial sale contract is signed.

When a contract of sale is signed after 31 December 2021, the seller must upgrade the home to the interconnected smoke alarm standard before it transfers to the buyer.

What does the home need?

• Photoelectric, not ionisation. Required alarms must be photoelectric. An alarm containing an ionisation sensor does not comply.
• Interconnected across the dwelling. Every alarm must be interconnected with every other alarm in the home, so that when one activates they all activate.
• Marked AS 3786-2014. The alarm must comply with Australian Standard 3786-2014. The marking is on the body, you may need to lift it off the bracket to read it.
• Hardwired, or a sealed 10-year battery. Either hardwired to mains with a secondary power source, or powered by a non-removable 10-year battery.

Alarms are required in each bedroom, on each storey, and in the hallways that connect bedrooms to the rest of the home. Every rule is in our guide to Queensland smoke alarm laws.

What is the Form 24?

The seller declares to the buyer that this obligation has been met on a Property Information (Transfer) form, commonly called a "Form 24". It is a standard compliance statement, usually provided by a conveyancer.

What paperwork shows the work was done?

Hardwired interconnected smoke alarms need a Certificate of testing and compliance, issued under section 227 of the Electrical Safety Regulation 2013.

When selling a home, you may need to provide proof that you have complied with the legislation.

Selling a manufactured home in a residential park
