WA compliance
Selling or Renting Out a Home in WA? Smoke Alarms Are Checked at Settlement
Under WA's Building Regulations 2012, a home must have mains-powered (hardwired) smoke alarms before it's sold, rented, or hired out. Settlement agents ask for it; a non-compliant alarm found late in a sale becomes a last-minute scramble.
The rules are specific, and three of them catch people out more than the rest:
- AS 3786 and placement:
- alarms must comply with Australian Standard AS 3786 and be positioned to the Building Code, so every storey is covered, sleeping areas are protected, and units sit clear of dead-air corners.
- The 10-year rule:
- every alarm has a manufacture date printed on it, and once it's a decade old it no longer counts as compliant, even if it still beeps when you press the button.
- Licensed work only:
- in WA, only a licensed electrical contractor can connect or disconnect a mains-powered smoke alarm. It's not a hardware-store DIY job.
For rentals, the Residential Tenancies Act 1987 puts the same obligation on the lessor, and the alarms must be kept in working order for the whole tenancy. Glen checks what you've got, tells you exactly what WA requires for your home, and gives you one fixed price to make it compliant, usually in a single visit, with paperwork for your records.
Selling, Leasing, or Just Sick of the Chirping?
Selling and want the RCDs checked in the same visit? That's the pre-sale electrical compliance check. Managing rentals? JEC handles smoke alarm compliance for rental properties across the northern corridor. Not selling? Same service applies if an alarm is chirping, yellowing with age, or was never hardwired in the first place.
What we do
Smoke Alarm Installation for Homes Across Perth's Northern Suburbs
JEC installs hardwired smoke alarms in homes across Joondalup and Perth's northern suburbs. Every alarm is mains-powered, AS 3786-compliant, positioned to the Building Code, and tested before Glen leaves.
- New hardwired smoke alarm installation: mains-powered alarms wired in by a licensed electrician, as WA requires
- Pre-sale and pre-lease compliance: checking age, type, and placement of every alarm so settlement or a new tenancy isn't held up
- 10-year replacements: swapping expired alarms for new units (the manufacture date on the alarm tells the story)
- Correct positioning: on or near the ceiling, clear of dead-air corners, at least 300mm from where ceiling meets wall, covering sleeping areas on every level
- 10-year lithium battery alarms where wiring isn't possible: WA permits sealed long-life battery units only where there's no cavity to run wiring, such as concrete ceilings. Glen will tell you straight if your home qualifies
- Compliance paperwork: provided for your records, useful for settlement, leasing, and insurance
If the alarm circuit itself is the problem (old wiring, no spare capacity on the board), Glen will quote the fix at the same visit rather than patching around it. See house rewiring and switchboard upgrades.
WA's smoke alarm rules
Under WA's Building Regulations 2012, smoke alarms must be mains-powered, comply with AS 3786, be positioned to the Building Code, and be no more than 10 years old before a home is sold, rented, or hired out. Only a licensed electrical contractor can connect or disconnect a mains-powered alarm; for rentals, the Residential Tenancies Act 1987 requires alarms to be kept working for the whole tenancy.
The difference
Old Battery Alarms vs Hardwired Photoelectric
-
Power
Old battery alarms
A 9V battery you have to remember to replace
Hardwired photoelectric
Mains powered with a 10-year backup, no flat-battery beeps
-
Interconnection
Old battery alarms
Standalone; only the alarm that senses smoke sounds
Hardwired photoelectric
Interconnected; if one goes off, they all do
-
Detection
Old battery alarms
Often ionisation, slower on smouldering fires
Hardwired photoelectric
Photoelectric, faster on the smoke that hurts people
-
Sale / lease in WA
Old battery alarms
May not meet current requirements
Hardwired photoelectric
Meets WA requirements for sold and rented homes
-
Lifespan
Old battery alarms
Varies, easy to forget
Hardwired photoelectric
Sealed 10-year units, replaced on schedule
Wiring in a hardwired alarm is licensed electrical work in WA. Glen fits and certifies them.

Smoke Alarm Questions, Answered
What are the smoke alarm requirements when selling a house in WA?
Before ownership of a WA home is transferred, it must have mains-powered smoke alarms that comply with AS 3786, are positioned to the Building Code, and are no more than 10 years old or past their expiry date. This sits under the Building Regulations 2012, and the seller is responsible for meeting it before settlement.
What about rental properties?
Lessors in WA must ensure the rental has compliant mains-powered smoke alarms before a tenancy starts and keep them in working order throughout it, under the Residential Tenancies Act 1987 and the Building Regulations 2012. Faulty alarms have to be repaired or replaced promptly, and units older than 10 years must be replaced.
Can I just use battery-powered smoke alarms?
Generally no. WA requires smoke alarms to be mains-powered where a home is being sold, rented, or hired. Battery alarms are only permitted where there's no concealed space to run wiring (a concrete ceiling is the classic case) and then only sealed units with a 10-year battery that can't be removed. Local government approval may also be required.
How do I know how old my smoke alarms are?
Twist or unclip the alarm and look for the manufacture date printed on the unit. Every compliant alarm has one. If it's 10 or more years back, or the alarm has yellowed and there's no date at all, it's due for replacement. Glen checks dates on every alarm as part of a compliance visit.
Where do smoke alarms need to be installed?
To the Building Code: on every storey of the home, positioned so sleeping areas are protected, mounted on or near the ceiling, and kept at least 300mm from the corner where ceiling meets wall so they are out of dead-air space. Placement is half of compliance: a working alarm in the wrong spot can respond late.
Are photoelectric smoke alarms better?
WA's Department of Fire and Emergency Services recommends photoelectric alarms, which detect smouldering, smoky fires faster than ionisation types. When JEC replaces old alarms, photoelectric is the default choice.
