Smoke alarms tend to sit quietly on the ceiling, gathering very little attention until they chirp at 2 am or burnt toast sets one off.

That quiet role can make them easy to overlook. For Melbourne landlords, though, the rules have become much clearer. Since 25 November 2025, every Victorian rental property must have its smoke alarms checked at least once every 12 months, regardless of when the rental agreement began. The alarms must be correctly installed, working and tested in line with the manufacturer’s instructions.

Landlords already working with Melbourne’s go-to electrician may be able to combine hard-wired alarm work with other property maintenance. Owners arranging electrical services across Melbourne should still understand what the annual smoke alarm visit covers, what it doesn’t cover and what happens when an alarm fails.

Because pressing a button is part of the check. It isn’t the whole check.

The Rule Is Already in Force

The annual requirement isn’t waiting for a future deadline.

It now applies to all Victorian rental agreements, including agreements that began before 29 March 2021. Rental providers and their agents are responsible for arranging the annual check.

That date matters because some landlords may still associate newer rental safety duties with recently signed leases. Smoke alarms are different. The annual check now covers the full rental market.

A townhouse leased last month needs it. So does a unit occupied by the same renter for six years. A long-running agreement doesn’t place the property outside the rule.

For property managers handling a large portfolio, the practical job is fairly simple on paper: identify the date of the last valid check, set the next due date and make sure the visit occurs within the 12-month cycle.

Simple on paper, anyway. Once access, tenant schedules and repairs enter the picture, things can get a little more lively.

What Does the Annual Check Actually Confirm?

The annual check should confirm that every smoke alarm at the rental property is correctly installed and in working condition.

It should also confirm that the alarm has a battery where one is required, that the battery is suitable and that the unit responds when tested according to its manufacturer’s instructions. Victorian rules require smoke alarms to be tested at least once every 12 months.

This means the person carrying out the check needs to look beyond the comforting sound of one loud beep.

The alarm should be secure rather than hanging loose from the ceiling. It shouldn’t be painted over, covered, cracked or clogged with obvious dust. Its power source needs attention. The unit’s age and expiry information should also be checked because smoke alarms don’t last forever.

Fire Rescue Victoria recommends replacing all smoke alarm units after ten years. It also advises replacing removable batteries each year, while alarms with sealed ten-year batteries don’t need an annual battery change.

So yes, the test button matters. But a button that makes noise doesn’t automatically tell the full story.

Hard-Wired Doesn’t Mean Maintenance-Free

There’s a common assumption that a mains-powered alarm can be forgotten because it isn’t relying only on a removable battery.

Not quite.

Hard-wired alarms still have backup batteries, sensors and internal components that age. They can collect dust. They can develop faults. Their backup batteries may need replacement unless the unit uses a sealed long-life battery.

A green indicator light can show that mains power is present, but it doesn’t replace a functional test.

The alarm still needs to sound when tested. Its backup supply still matters because a house fire and a power failure can occur at the same time. Storm damage, a tripped circuit or heat affecting cables may remove mains power just when the warning system is needed.

The backup battery isn’t an optional extra. It’s the second goalkeeper.

Cleaning Is Small, but It Matters

Dust, cobwebs and insects can affect smoke alarms.

Fire Rescue Victoria recommends cleaning smoke alarms at least once each year using a vacuum cleaner or a gentle clean around the cover. Monthly testing is also encouraged, even though the rental provider’s formal check is annual.

This is one of those small maintenance jobs that feels almost too ordinary to mention. Yet ordinary things often decide whether safety equipment behaves as intended.

An annual service visit is a good time to remove surface dust and check for contamination. It’s also an opportunity to look for alarms that have been painted during renovation work or partly covered because someone was tired of false alarms.

You know what? A smoke alarm that keeps reacting to cooking may be badly located, dirty or reaching the end of its life. Removing the battery is not a fix.

It simply removes the warning.

The Tenant Has Responsibilities Too

Landlords and agents must arrange the annual check, but renters aren’t passive in the process.

Renters must tell the rental provider if a smoke alarm is faulty or not working. They must not remove it, deactivate it or interfere with its operation. Taking out the battery because the alarm chirps is not allowed.

The sensible relationship is straightforward.

The landlord arranges inspections and repairs. The renter reports faults between checks. Both sides allow the alarm to keep doing its job.

At the start of a rental agreement, the provider must also give the renter written information explaining how each alarm operates, how it should be tested and the renter’s obligation not to tamper with it.

That written information is more useful than it sounds. Different alarms have different buttons, indicator lights and battery arrangements. A renter shouldn’t need to study the ceiling like an archaeologist just to work out why a unit is chirping.

A Broken Alarm Is an Urgent Repair

If a renter reports that a smoke alarm isn’t working, the landlord can’t wait for the next annual visit.

A broken smoke alarm is treated as an urgent repair. The rental provider or rooming-house operator must immediately arrange for it to be repaired or replaced. If the provider can’t be contacted or doesn’t act, the renter may arrange an urgent repair costing up to $2,500 and seek repayment within the required timeframe.

That rule makes sense.

An annual check is a scheduled safety measure. It isn’t permission to leave a failed device out of service for weeks.

Imagine an alarm failing one month after its annual test. Waiting another eleven months would defeat the point entirely.

The same thinking applies when an alarm begins emitting an occasional chirp. It may need a new battery, or the unit itself may be faulty. Either way, the sound deserves attention rather than a broom handle and a muttered complaint.

Annual Doesn’t Mean Forget About It for Eleven Months

The landlord’s formal duty is annual, but smoke-alarm awareness continues between visits.

Fire services recommend that occupants test alarms monthly. Batteries that can be replaced should be changed yearly, alarms should be kept clean and every unit should be replaced after ten years.

Landlords should also treat property changes as a reason to review the alarm system.

A bedroom may be added. A garage could be converted. Walls may move during renovation. A new upper floor could change escape routes and alarm placement.

The annual check catches many issues. Building work can create new ones before the next due date.

Smoke alarms are simple devices, but they sit inside a changing home.

The Check Is Really About Time

A working smoke alarm doesn’t extinguish a fire.

It buys time.

Time to wake up. Time to leave a bedroom. Time to guide children outside. Time to call emergency services before smoke and heat take over the escape path.

That’s why the annual check shouldn’t be treated as a property-management ritual or another invoice to file away. It confirms that a small device on the ceiling is ready to make a very large noise when people need it most.

For Melbourne landlords, the practical response is clear. Record the last check date, arrange the next visit before the 12-month mark and act immediately when an alarm is reported as faulty.

Check the installation. Check the battery. Check the age. Check that it sounds.

Then keep the record somewhere better than the bottom of an email inbox.
