Smoke Alarms for Brisbane Renovations
Buying and installing smoke alarms
Queensland’s smoke alarm laws went into effect on January 1, 2017. All new and significantly renovated dwellings must have interconnected photoelectric smoke alarms that comply with Australian Standard 3786-2014 (AS 3786-2014) installed by this date.
New and substantially built residences should have compliant smoke alarms installed as part of the construction process, as required by the National Construction Code (NCC). This is officially called the Building Code of Australia (BCA) and the Building Regulation 2006.
Hardwired or powered by a non-removable 10-year battery
Operate when tested.
The smoke alarms must be installed:
In every bedroom
In hallways connected with bedrooms
On each level of the home.
If there are no bedrooms on a storey, at least one smoke alarm must be installed in the exit path of the house.
Smoke alarms must be installed on the ceiling whenever possible. Smoke alarms must not be installed in the following areas:
300mm of a corner of a ceiling and a wall
300mm of a light fitting
400mm of an air-conditioning vent
400mm of the blades of a ceiling fan.
There are other specific requirements for sloping ceilings, stairways, and ceilings with exposed beams, which are explained in detail in the Building Fire Safety Regulation 2008.
Suppose a homeowner or landlord decides to install or replace a smoke alarm, regardless of the age of the home. In that case, it must be replaced with an AS 3786-2014 compliant interconnected photoelectric smoke alarm. These regulations will apply to all rented and sold residences beginning January 1, 2022. A landlord must comply by January 1, 2022 to rent their property legally. Property sellers must continue to file a Form 24 certifying that all legal requirements have been met. These regulations will apply to all homes beginning January 1, 2027.
Avoid dodgy traders
Dodgy dealers may try to take advantage of Brisbane’s new smoke alarm requirements. Make sure you understand the standards for your home to protect yourself. It is illegal for a company or dealer to tell you something false or deceptive. This includes the following:
In all advertising, for instance, on their website or a leaflet delivered to mailboxes
In emails, letters, or text messages, you get
On a shelf or other in-store labeling or signage
On product packaging
In conversations with you
Supply and demand
Every residential dwelling in Queensland must have compliant smoke alarms fitted by 2027. Given the high demand for products, availability may be limited, or prices may rise, mainly toward the cut-off date of January 1, 2027. The Queensland Government does not set smoke alarm prices; businesses can determine their costs. We strongly advise you to make your home compliant as soon as possible to avoid any potential supply and demand concerns.

Do I need to upgrade smoke alarms when renovating my Brisbane home?
Yes — under QLD legislation, the moment you carry out 'substantial renovations' to a Brisbane home, the smoke alarms in the renovated section must immediately meet the full 2027 standard: photoelectric, interconnected, and located in every bedroom, every hallway connecting bedrooms, and every storey. Even if you're only renovating one bedroom or adding an extension, the alarm requirements for that section trigger now — you don't get to wait for the 2027 deadline.
What counts as a 'substantial renovation' for smoke alarm purposes?
Queensland legislation defines it as renovation work requiring building approval — typically anything structural (extensions, wall removals, second-storey additions), full bathroom or kitchen rebuilds, or roof restoration involving new cabling. Cosmetic work (paint, flooring, fittings) generally doesn't trigger it. If you're unsure, we can read your plans and confirm whether your project triggers the alarm-upgrade requirement before you start, so it's costed in upfront.
Should I install hardwired or wireless interconnected alarms during a renovation?
If your renovation has the ceilings or walls open, hardwired interconnection is the right choice — it's marginally more reliable, has zero RF range issues, and adds almost nothing to the install cost while the cavities are already accessible. If only some of the home is being renovated and the rest is sealed, RF wireless interconnection is cleaner — it pairs the new alarms with the existing ones with no additional cabling. We assess this on a per-project basis at quote stage.
When in the renovation timeline should the smoke alarms go in?
Hardwired alarms should be roughed-in at the same stage as your other electrical (after framing, before plasterboard). Final alarms and the compliance test happen after painting and at sign-off, so the units aren't damaged or covered. We coordinate directly with your builder or sparky to lock in those two visits, and supply the dated compliance certificate when the building inspector signs the renovation off.
Will my Brisbane builder organise the smoke alarms for me?
Some do, some don't. Many Brisbane builders sub the smoke alarm work to a generalist sparky who treats it as a checkbox rather than a specialty — and we frequently see compliance failures (wrong locations, mixed brands, missing interconnection) that have to be redone. Asking your builder explicitly: 'who is supplying the dated AS 3786 compliance certificate?' is the right test. If they don't have a clear answer, get us in directly — we work alongside builders all over Brisbane.
What documentation will I need at the end of the renovation?
You'll need a dated, signed smoke alarm compliance certificate listing every alarm — its location, model, AS 3786 certification, manufacture date, and pass/fail test result. Brisbane City Council and your private certifier will ask for this at final sign-off. Insurance requires it. If you sell or lease the home in future, conveyancers and incoming property managers will ask for it. We hand it over on the day of final test, plus emailed PDF for your records.
