What NSW smoke alarm requirements actually mean for your property
The rules around smoke alarms in NSW have been updated progressively over recent years. The short version is: photoelectric alarms are required (not ionisation type), they must be on every level of the home, inside bedrooms and in hallways leading to bedrooms, and they must be functional at the start of each rental tenancy.
The practical question is whether your current alarms meet those requirements - which depends on their type, age, position and whether they’re interconnected as required for your property.
The 10-year lifespan problem
Most smoke alarms have a 10-year service life measured from the manufacture date on the back of the unit. This catches a lot of people out because the alarm may have been installed relatively recently but manufactured years before that. An alarm that’s been on the wall for five years could already be past its service life if it was old stock when installed.
The simplest check is to find the manufacture date on the alarm itself. If you can’t find it, or it’s past the 10-year mark, it needs replacing regardless of whether it still beeps when tested.
Landlord and property manager obligations
For rental properties, smoke alarm compliance is a condition of tenancy, not an optional upgrade. Alarms need to be tested and in working order at the commencement of each tenancy. Alarms that have reached their service life need to be replaced before the next tenancy begins.
Ed can assess the alarms at a rental property, identify which need replacing, and provide documentation of what was installed and its position. That documentation is useful if compliance is ever questioned.
Hardwired versus battery-powered alarms
Hardwired alarms with battery backup are generally preferred for permanent residential installations. They’re less vulnerable to flat batteries and typically support interconnection more reliably. Battery-only alarms are acceptable in some situations but may not be appropriate for all positions or property types. Ed will advise on the right approach for your property layout and rental status.
