If you’re a Melbourne homeowner or landlord and haven’t reviewed your smoke alarms recently, now’s the time. Victorian smoke alarm laws have been tightening over the past few years, and 2026 brings renewed focus on compliance, especially for rental providers.
The Basics: What Victorian Law Requires
Victorian smoke alarm legislation sits across a few key pieces of regulation: the Building Regulations 2018, the Residential Tenancies Regulations 2021, and the National Construction Code.
The rules vary depending on when your home was built, but a few requirements apply to every Victorian property:
- Photoelectric alarms only. Ionisation alarms no longer meet Victorian requirements, so if you have one, it needs to go. All alarms must be photoelectric and comply with Australian Standard AS 3786.
- Every level must have one. At least one smoke alarm must be installed on every level of the home.
- Replace every 10 years. Smoke alarms must be replaced every 10 years from the date of manufacture, not the installation date. Check the label on the back of the alarm for this date.
What’s Proposed for New Builds in 2026
As of early 2026, the Victorian Government is progressing legislation that would require smoke alarms inside every bedroom of newly built homes, not just outside sleeping areas, and would make builders and developers criminally liable if alarms are missing from bedrooms in new construction.
This hasn’t passed into law yet, but it’s worth keeping an eye on if you’re building or planning a major renovation.
If You’re a Landlord, Pay Close Attention
Rental providers (landlords) have the most specific obligations under Victorian law.
Landlords must install compliant smoke alarms before a tenancy begins or is renewed. Failure to comply can result in fines and legal liability.
Here’s a quick summary of your responsibilities:
- Annual testing is mandatory. An annual smoke alarm safety check is now mandatory, not just recommended.
- Test before each new tenancy. Before a new tenant moves in, all alarms must be confirmed as working.
- Power requirements. Smoke alarms in a rental must be either hardwired into the property’s electrical system or, for wireless interconnected alarms, powered by a non-removable, 10-year lithium battery. Standard replaceable batteries don’t cut it for rentals.
- Tenants must report faults. Tenants are required to report any faults or malfunctions to the landlord promptly, but the maintenance obligation remains with you.
What Homeowners Need to Do
Owner-occupiers have a little more flexibility, but the core requirements still apply. Make sure your alarms are photoelectric, correctly located, less than 10 years old, and tested regularly.
Test all smoke alarms every month by pressing and holding the test button until the alarm sounds. It takes about 10 seconds and could save your life.
Not Sure If You’re Compliant?
If you’ve got older alarms, a recently renovated home, or a rental property that hasn’t been checked in a while, it’s worth getting a professional to take a look. An electrical safety check covers your smoke alarms alongside your broader electrical setup, giving you a clear picture of where you stand.
