If you live in an older Brisbane home, there is a good chance your smoke alarm setup is outdated — even if the alarms still appear to work.
That is one of the biggest problems we see across North Brisbane and Moreton Bay. Homes built years ago often still have old ionisation alarms, expired units, no bedroom alarms, or no interconnection between alarms. They may have been acceptable at the time, but they often fall short of what is now required under Queensland law.
At Brisbane Smoke Alarm, we help homeowners upgrade older properties with compliant photoelectric interconnected smoke alarms across Brisbane, North Brisbane, Moreton Bay, Redcliffe, North Lakes, Caboolture, Pine Rivers and nearby suburbs.

Why Older Homes Often Need Smoke Alarm Upgrades
Many older homes were fitted with smoke alarms under older standards or piecemeal over time. That means the current setup may have gaps that are easy to miss unless the property is checked properly.
Common issues include:
- alarms older than 10 years
- old ionisation alarms still installed
- no smoke alarms inside bedrooms
- no interconnection between alarms
- poor placement that leaves sleeping areas less protected
- extra rooms or renovations added after the original alarm layout
That is why an older home can still have alarms on the ceiling and still not be properly protected.
What Queensland Law Requires by 1 January 2027
Queensland homes must have smoke alarms that are:
- photoelectric
- interconnected
- installed in every bedroom
- installed in hallways connecting bedrooms
- installed on every storey
- compliant with AS 3786:2014
That means a large number of older Brisbane homes will need smoke alarm upgrades before 2027.
If the property has not been reviewed in years, there is a strong chance changes are needed.
Signs Your Older Home May Need a Smoke Alarm Upgrade
- the alarms are more than 10 years old
- the property still has yellowed or older-style alarm units
- there is no alarm inside each bedroom
- only one alarm sounds when tested
- the home has been renovated or extended
- you are unsure what type of alarms are installed
- the system has never been checked against current Queensland requirements
If that sounds familiar, it is worth booking an inspection rather than guessing. A smoke alarm check for an elderly home is usually the best starting point if the property also has an older resident.
What an Upgrade Usually Involves
Every property is different, but most older home smoke alarm upgrades involve:
- removing expired or outdated alarms
- installing photoelectric smoke alarms
- setting up full interconnection between alarms
- adding alarms to bedrooms where required
- improving hallway and storey coverage
- making sure the final setup aligns with current Queensland requirements
Some older homes need only a straightforward upgrade. Others need a more thoughtful layout because of extensions, sleepout conversions, split levels, or changed room use over time. If the resident is elderly or has hearing loss, you may also want to review our guidance on smoke alarms for elderly parents or hearing-impaired smoke alarm options.
Why Older Brisbane Homes Need More Thoughtful Alarm Placement
Older homes are not always simple.
We regularly see properties with enclosed verandas, converted sleepouts, hallway changes, rear extensions, granny flat-style additions, or room uses that have changed since the home was first built.
That is one reason generic advice is not enough. A proper smoke alarm upgrade should consider how the home is actually used now — not just how it looked on an old plan.

Frequently Asked Questions
Do older homes need different smoke alarms?
Older homes usually need the same current legal standard as other homes: photoelectric, interconnected alarms in the right locations. The difference is that older homes are more likely to have outdated systems that need upgrading.
What if my smoke alarms still work?
Working does not always mean compliant or well positioned. If they are over 10 years old, not interconnected, or not photoelectric, they may still need replacing.
Can you upgrade alarms in renovated or extended homes?
Yes. In fact, homes with extensions or changed layouts often benefit most from a proper review because the original alarm layout may no longer suit the way the home is used.
Can you inspect first before quoting the upgrade?
Yes. That is usually the best place to start.
