Queensland’s smoke alarm legislation has been rolling out in stages since 2017, and the date that catches most homeowners off guard is the last one: 1 January 2027, when every remaining owner-occupied home in the state has to be compliant. If you own and live in your home and haven’t touched your smoke alarms since they were installed, there’s a good chance they don’t meet the standard — not because they don’t work, but because the law changed around them.
This is a plain guide to what the legislation actually requires, who has to comply and by when, and what a compliant setup looks like in a typical Brisbane home.
The three deadlines
| Date | Applies to |
|---|---|
| 1 January 2017 | All new dwellings and any home undergoing substantial renovation |
| 1 January 2022 | Every home sold or newly leased (already in effect) |
| 1 January 2027 | Every remaining owner-occupied home in Queensland |
Source: Queensland Fire Department. If your home was sold or newly leased on or after 2022, it should already be compliant — the 2027 date is for owner-occupiers who haven't sold, leased or substantially renovated since.
In practice, that means the only homes still running the old rules by 2027 are ones that have been owner-occupied the whole way through, with no sale, new lease or major renovation to trigger an earlier upgrade. If that’s your situation, the clock is already running.
What “compliant” actually means
Three separate requirements have to be met together — type, placement and interconnection. Meeting two out of three doesn’t count.
- ✓Photoelectric alarms only, certified to AS3786:2014. Older ionisation alarms — still common in homes fitted out before the mid-2010s — do not meet the Queensland standard, even if they’re working and in-date. Photoelectric alarms respond faster to the smouldering, smoky fires that are more common and more deadly in a home at night.
- ✓An alarm in every bedroom. Not just the hallway outside them.
- ✓An alarm in every hallway that connects bedrooms to the rest of the house, or in the nearest hallway to a bedroom if there’s no connecting hallway.
- ✓An alarm on every storey, even levels with no bedrooms.
- ✓All alarms interconnected, so that one alarm triggering sets off every alarm in the house. This can be hardwired or wireless interconnection — the standard doesn’t require rewiring if a compliant wireless-interconnect system is fitted instead.
Ionisation alarms are the most common trap
A lot of Brisbane homes have alarms that look fine, beep on test and are well within their use-by date — and still don’t comply, because they’re the older ionisation type rather than photoelectric. There’s no way to tell from across the room; it's printed on the alarm itself, or we check it as part of the inspection.
Why interconnection is the part people skip
A single alarm in a bedroom with the door shut can go off and not be heard anywhere else in the house. Interconnection means every alarm sounds together — the alarm in a sleeping child’s room can wake the whole household, not just that room. It’s the single biggest functional difference between an older setup and a compliant one, and it’s also the part that can’t be added alarm-by-alarm from a hardware store shelf; it has to be installed as a system.
Battery, hardwired, or 10-year lithium?
- ✓Hardwired alarms run off the home’s mains power with a battery backup, and interconnect over their own wiring. The standard approach for a full upgrade, and the most reliable long-term.
- ✓10-year lithium alarms run on a sealed, non-replaceable battery rated for the alarm’s working life, and interconnect wirelessly. A practical option where running new cable through a finished ceiling isn’t straightforward.
- ✓Replaceable-battery alarms are the older style and generally not what goes in on a compliant upgrade — they’re the type most likely to end up silenced with a flat battery rather than replaced.
Every smoke alarm, whatever the type, has a use-by date printed on the unit — typically 10 years from manufacture. An in-date alarm that fails the type or interconnection test still needs replacing; an out-of-date alarm needs replacing regardless of type.
What this looks like in a typical Brisbane home
Most of the older housing stock across Coorparoo, Camp Hill, Carina and the surrounding suburbs — Queenslanders and post-war homes with three bedrooms off a single central hallway — needs four alarms as a baseline: one per bedroom and one in the connecting hallway, all interconnected. A two-storey home adds at least one more for the second level, even if there’s nothing but a stairwell and a living area up there.
Homes we’ve already upgraded a switchboard or done a rewire for often already have some of the wiring run for a hardwired interconnected system, which usually brings the job in cheaper than starting from nothing.
What we charge
We keep this simple and publish it rather than quoting a range and hoping it lands close:
| Service | Price |
|---|---|
| Once-off smoke alarm service | $150 |
| Annual smoke alarm service | $120 |
| Annual service — one-bedroom or studio | $99 |
Prices include GST. A full compliance upgrade (new interconnected photoelectric alarms) is quoted on site, since alarm count and access vary by home.
What a service or upgrade visit covers
- 1Check every existing alarm for type (photoelectric vs ionisation), use-by date and physical condition.
- 2Confirm placement against the three-part rule: bedrooms, connecting hallways, every storey.
- 3Test interconnection — one alarm triggered, every alarm should sound.
- 4Replace, add or reposition alarms as needed to bring the home into compliance.
- 5Clean dust from alarm sensors, which is the single most common cause of false alarms and nuisance beeping.
- 6Leave the home with a record of what’s installed and when it’s next due.
Selling or leasing soon?
If a sale or new lease is coming up, get this done well before settlement or the new tenancy starts — it’s already a legal requirement for both, not just an owner-occupier deadline, and it’s far easier to arrange on your own timeline than under pressure from a contract condition.
Not sure if your alarms comply? We’ll check them properly.
