Navigating Queensland’s New Smoke Alarm Legislation

Queensland Smoke Alarm Laws 2025 | What You Need to Know

Updated Smoke Alarm Requirements for Brisbane Homeowners and Landlords

Queensland’s smoke alarm legislation has changed significantly in recent years. All homes — whether owner-occupied, rented or sold — must now comply with updated requirements for interconnected photoelectric smoke alarms. For homeowners and landlords across North Lakes, Redcliffe, Mango Hill and Chermside, understanding these requirements is essential to avoid penalties and protect your household.

What Does Queensland Law Require?

Under the Fire and Emergency Services Act, all Queensland homes must have:

Photoelectric smoke alarms (not ionisation type)
Alarms installed in every bedroom
Alarms in hallways that connect bedrooms to the rest of the home
Alarms on every level of the home
All alarms interconnected so when one triggers, they all sound
Alarms that are either hardwired or use sealed 10-year lithium batteries

Compliance Deadlines

Property Type	Compliance Deadline
New builds and major renovations	From 1 January 2017
Rental properties, boarding houses, short-term accommodation	1 January 2022
Properties sold or transferred	1 January 2022
All other dwellings (owner-occupied)	1 January 2027

If you are a landlord or planning to sell your property, your home must already comply. Owner-occupied homes have until 1 January 2027, but upgrading now avoids the last-minute rush and ensures your family is protected.

What Is the Difference Between Photoelectric and Ionisation Alarms?

Ionisation alarms respond faster to fast-flaming fires but are slower to detect smouldering fires, which are the most common type of fatal house fire. Photoelectric alarms detect smouldering fires earlier, giving occupants more time to escape. Queensland law now requires photoelectric alarms because they provide better protection against the most dangerous fire types.

What Does Interconnected Mean?

Interconnected means that when one alarm detects smoke, all alarms in the home sound simultaneously. This ensures that occupants in any part of the house are alerted, even if the fire starts in a distant room. Interconnection can be achieved through hardwiring or wireless RF (radio frequency) linking.

Hardwired interconnection is the most reliable option and is standard for new installations. A licensed electrician can install hardwired interconnected smoke alarms throughout your home.

How Much Does Smoke Alarm Compliance Cost?

Service	Typical Cost Range (AUD)
Single smoke alarm (supplied and installed)	$80 – $150
3-bedroom home full compliance	$500 – $1,000
4-bedroom home full compliance	$700 – $1,200
Wireless interconnection upgrade	$400 – $800
Hardwired interconnection (new wiring)	$600 – $1,500

These are guide prices only. The cost depends on the number of alarms needed, whether new wiring is required and the layout of your home. If your switchboard is older, it may need attention as part of the installation.

Penalties for Non-Compliance

Landlords who fail to comply with smoke alarm requirements face penalties of up to $7,732 per offence. For property sales, non-compliance can delay settlement or result in the buyer requiring compliance as a condition of the contract.

Beyond penalties, non-compliant smoke alarms put lives at risk. House fires can become unsurvivable within 3 to 5 minutes — working smoke alarms provide the early warning that saves lives.

What Should Landlords Do?

Audit all rental properties for current smoke alarm compliance
Replace any ionisation alarms with photoelectric models
Ensure alarms are installed in every bedroom and connecting hallway
Ensure all alarms are interconnected
Keep records of installation dates, testing and maintenance
Test alarms at every change of tenancy

What Should Homeowners Do?
