Smoke alarms are a legal requirement across Tasmania and must be installed correctly and kept in working order. Under the National Construction Code and applicable Tasmanian building regulations, every residential property needs a working smoke alarm on every level of the home. All alarms must comply with Australian Standard AS 3786:2014.
The type of alarm required, how it is powered, whether it needs to be interconnected, and who is responsible for maintenance all depend on when the property was built and whether it is rented.
Here are the main smoke alarm laws Tasmania homeowners and landlords should know:
Basic Requirements
- At least one working smoke alarm must be installed on every level of the home.
- Smoke alarms must comply with Australian Standard AS 3786:2014.
- Alarms must be installed in every hallway or corridor connected to bedrooms, or in the area between the bedroom and the rest of the level where no hallway exists.
Rental Property Requirements
- All smoke alarms must be either mains-powered or fitted with a non-removable 10-year lithium battery.
- Alarms must be tested and confirmed to be working before a new tenancy begins.
- Faulty alarms must be repaired or replaced as soon as practicable after the rental provider is notified.
- Alarms must be replaced every 10 years from the date of manufacture.
New Builds & Building Work
- Properties built or substantially renovated on or after 1 May 2014 require alarms to be hardwired to 240V mains power.
- Where more than one alarm is required, alarms must be interconnected so that when one sounds, they all sound.
- A licensed electrician must install hardwired smoke alarms.
Note: This is a general guide only. Requirements can vary depending on the property’s age, layout, and whether it has been renovated or extended. If you are unsure, speak with a licensed electrician or fire safety professional.
Tasmania smoke alarm laws apply to all residential properties. Requirements vary based on when the property was built or last renovated.
The timeframes are as follows:
Smoke alarms should be installed so they provide the earliest possible warning to people in sleeping areas. In practical terms:
- Install at least one alarm on every level of the home.
- Place alarms in hallways or corridors connecting bedrooms to the rest of the level.
- Where there is no hallway, install an alarm between the bedroom area and the rest of the level.
- In multi-storey homes, install an alarm at the top of all stairways.
- Mount alarms on the ceiling where possible, at least 30cm from walls and away from air vents and cooking appliances.
The Tasmania Fire Service recommends going further: a smoke alarm in every bedroom, living area and garage, and at the top of each stairwell. Interconnecting alarms so they all sound together is strongly recommended, even where it is not yet a legal requirement for older properties.
Keep alarms away from bathrooms, cooking areas, and air conditioning vents. Steam and cooking fumes can trigger false alarms.
The Tasmania Fire Service recommends photoelectric smoke alarms for all sleeping areas, living areas, hallways, and stairwells, specifically a photoelectric alarm with a 10-year-long-life lithium battery.
Photoelectric alarms are better suited to the slow, smouldering fires that typically start in bedrooms overnight, giving families more time to escape. They also produce fewer nuisance alarms from cooking fumes or steam, and contain no radioactive material.
Ionisation alarms are not prohibited under current Tasmanian legislation, but they are not recommended. If existing alarms are approaching 10 years old, replacing them with photoelectric alarms is the right choice. For rental properties, meeting current standards effectively means installing photoelectric alarms.
The rules below are based on how buildings are classified under the National Construction Code. If you’re not sure which category applies to your property, a licensed electrician or building surveyor can confirm it.
Houses, Townhouses and Granny Flats (Class 1a)
Install an alarm on every level. In levels with bedrooms, place an alarm in the hallway connecting those bedrooms to the rest of the home. If there is no hallway, install one between the bedroom area and the rest of that level. For a granny flat or self-contained ancillary dwelling, place an alarm between the sleeping area and the rest of the space.
Small Guesthouses and Boarding Houses up to 12 Guests (Class 1b)
Install an alarm on every level. On levels with bedrooms, fit an alarm in each bedroom and in any hallway serving those bedrooms. Where there is no hallway, place one between the bedroom area and the rest of the floor. Alarms are also required on levels with no bedrooms.
Apartments and Blocks of Flats (Class 2)
Each apartment needs an alarm on every level. On levels with bedrooms, install an alarm in each hallway serving those bedrooms, or between the bedroom area and the rest of the apartment, where there is no hallway. On levels without bedrooms, alarms must be installed along escape routes.
Boarding Houses and Caretaker Residences (Class 3 and 4)
Follow the same rules as the apartments above.
Caravans, Boats and Mobile Property
The Tasmania Fire Service recommends installing a smoke alarm in all caravans, boats and mobile properties where people sleep. A long-life lithium battery alarm is the most practical option.
If you are unsure which building class applies to your property, speak with a licensed electrician, building surveyor, or contact CBOS Tasmania directly.
Home Owner / Occupier
- Ensure smoke alarms that comply with AS 3786:2014 are installed in all required locations.
- Test each alarm at least once every 12 months.
- Clean alarms regularly and replace the unit when it reaches the end of its service life (10 years from the manufacture date).
- For hardwired alarms, replace the stand-by (backup) battery immediately if it is spent.
Rental Provider (Landlord or Agent)
- Install photoelectric smoke alarms that comply with AS 3786:2014 in the required locations.
- Ensure alarms are either mains-powered or fitted with a sealed, non-removable 10-year lithium battery.
- Clean, test and confirm all alarms are working before the start of each new tenancy.
- Replace any faulty alarm as soon as practicable after being notified.
- Replace all alarms every 10 years from the manufacture date.
Note for property managers: alarms must be tested and working before the tenancy starts, not necessarily on move-in day itself. Build this into your pre-tenancy inspection schedule. Compliance is overseen by Consumer, Building and Occupational Services (CBOS) Tasmania. Rental providers who fail to meet their obligations may be subject to a smoke alarm infringement notice.
Renter (Tenant)
- Test and clean alarms regularly during the tenancy.
- Keep alarms clear of dust and debris.
- Notify the rental provider promptly if a fault is found.
- Do not remove, disable or tamper with any smoke alarm.
