All rental properties must have working smoke alarms that meet the legal requirements - it is important that both landlords and tenants understand their legal obligations to install and maintain smoke alarms.

What are the smoke alarm requirements?

From 1 July 2016, it has been compulsory for all rental properties to have installed, working smoke alarms.

Mandatory Requirements

Every rental property must meet the following requirements:

There must be at least one working smoke alarm within 3 metres of each bedroom door or every room where a person sleeps.
There must be at least one working smoke alarm in self-contained caravans, sleep outs, or similar structures.
There must be at least one working smoke alarm on every level of a multi-level or multi-storey home. This includes on every level of split levels.

Installing New Smoke Alarms

If you install a new smoke alarm after 1 July 2016, it must meet the following requirements:

The smoke alarm must be photoelectric.
The smoke alarm must have a battery life of at least 8 years OR be hard-wired.
The smoke alarm must be installed according to the manufacturer’s instructions.
The smoke alarm must meet international standards.

Working Smoke Alarms installed pre-1 July 2016

Provided that any existing smoke alarms installed before 1 July 2016 are working and they are in the required locations under the Mandatory Requirements (above), then they do NOT need to meet the requirements for new alarms installed after 1 July 2016.

When do pre-1 July 2016 smoke alarms need to be replaced?

Any smoke alarm, including pre-1 July 2016 alarms, must be replaced if or when:

  • they stop operating or functioning correctly
  • the alarm reaches the replacement date listed on it
  • if there is no replacement date, when the alarm is more than 8 years old
  • if you don’t know how old the alarm is

If you replace a pre-1 July 2016 smoke alarm, the new alarm must meet the requirements (listed above) for post-1 July 2016 smoke alarms.

Who is responsible for smoke alarms?

Responsibility for smoke alarms is shared by landlords and tenants. Landlords may be subject to fines of up to $7,200 and tenants of up to $4,000 for failing to meet their obligations.

Landlord’s Responsibilities

Landlords are responsible for ensuring that the property has smoke alarms that meet the requirements (above) at the beginning of the tenancy. This means that before the start of every tenancy the landlord must ensure that the alarms are working and meet the minimum requirements for location, type, and age.

Tenancy law gives landlords the right to enter their rental property after 24 hours notice for the purpose of complying with smoke alarm requirements. In this circumstance, entry must be made between 8am and 7pm.

Tenant’s Responsibilities

Tenants must do the following:

  • Replace dead or dying batteries during the tenancy if the alarms have replaceable batteries.
  • Notify the landlord as soon as possible if any smoke alarm becomes faulty or if there are any problems with the alarms.
  • Avoid damaging, removing, or disconnecting any smoke alarm.

    I have had numerous fire alarms that are supposed to last 10 years, only work for 4 years or less. The new photoelectric smoke alarms are a pain in the butt. I keep replacing them, and go to Bunnings for replacement. I keep all receipts now. I would rather have the regular battery smoke alarm.
