Owning a property

Smoke alarms

Smoke alarms can help save lives by providing occupants with an early warning about house fires. A smoke alarm can help you and your family leave your home quickly in case of a fire, especially if you are asleep.

All South Australian homes must be fitted with a working smoke alarm. Homeowners and residential landlords are responsible for ensuring a working smoke alarm is installed in the property.

Fines of up to $750 apply if alarms are not installed. The type of smoke alarm you require depends on when you purchased your home or the age of your home.

Homes or residential rental properties purchased before 1 February 1998

You are required to fit a replaceable battery powered smoke alarm.

Homes or residential rental properties purchased on or after 1 February 1998

Regulation 76B of the Development Regulations 2008 requires a smoke alarm (or smoke alarms) be fitted within six months from the day on which title is transferred and be either:

  • a 240 volt, mains-powered smoke alarm
  • a 10-year life, non-replaceable, non-removable, permanently connected battery powered smoke alarm.

Homes or residential rental properties built on or after 1 January 1995

The Building Code of Australia requires a 240 volt, mains powered smoke alarm.

Interconnection of smoke alarms

New dwellings and new additions or extensions to existing dwellings require the interconnection of smoke alarms. Interconnecting smoke alarms means that when one alarm is activated, it will activate all other alarms in the occupancy. Further advice is available in Advisory Notice 05/14 New requirements for the interconnection of smoke alarms.

Where to buy smoke alarms

Smoke alarms can be purchased from:

  • department stores
  • hardware stores
  • electrical retailers
  • security companies
  • fire protection companies

Where to install smoke alarms

Smoke alarms should be installed in a convenient location to give occupants reasonable warning when they are asleep.

Depending on the size and layout of your home, it may be necessary to install more than one smoke alarm to provide sufficient warning.

Rental properties and landlord responsibilities

In a rental property, it is the responsibility of the building owner or landlord to install and maintain working smoke alarms.
