Particle levels while cooking with an unvented stove can reach 10x higher than our health-based limits for outdoor air pollution, and they can linger indoors for hours. FIND OUT MORE ABOUT THE Healthy Homes Standard and Ventilation REQUIREMENTS.
If you own a rental property, you must have the following:
- Mechanical ventilation in rooms with a bath, shower or indoor cooktop, and
- Openable windows or external doors in the living room, dining room, kitchen and bedrooms.
If you need to install an extractor fan or kitchen rangehood, in most cases, electrical work must be performed by a licensed electrician.
G-Force not only installs, but we can supply a range of ventilation options for your rental.
Don’t forget:
- Recirculating extractor fans or fans that do not ventilate to the outdoors are not suitable for meeting the healthy homes ventilation standard.
- There are specific size or performance requirements for new extractor fans to ensure they are effective.
- When existing extractor fans installed before 1 July 2019 stop working, they must be replaced with extractor
- In most cases, a rangehood is the most effective type of extractor fan for kitchens.
Requirements for kitchen extractor fans
- Installed FROM 1 July 2019: The fan and all exhaust ducting must have a diameter of at least 150mm OR the fan and all exhaust ducting must have an exhaust capacity of at least 50 litres per second. The fan must vent extracted air to outdoors.
- Installed BEFORE 1 July 2019: No minimum size or performance requirements but fans must be in good working order and ventilate to outdoors. This means that the range hood or extractor fan must not vent back into the kitchen, into a roof space or other space. Any ducting must be connected, intact (i.e. without tears or holes) and installed so that extracted air can flow freely through it (e.g. no unnecessary kinks or compressions). Any grills or filters must be unclogged.
Requirements for bathroom extractor fans
- Installed AFTER 1 July 2019: The fan and all exhaust ducting must either have a diameter of at least 120mm OR the fan and all exhaust ducting must have an exhaust capacity of at least 25 litres per second. The fan must vent extracted air to outdoors. Continuously operating extractor fans that operate at a level of extraction below 25 litres per second, or do not have a fan and ducting diameter of at least 120mm, are not capable of providing the necessary level of moisture extraction during a shower.
- Installed BEFORE 1 July 2019: No minimum size or performance requirements but fans must be in a good working order and ventilate to outdoors. This means that the extractor fan must not vent extracted air into a roof space or other space. Any ducting must be connected, intact (i.e. without tears or holes) and installed so that exhaust air can flow freely through it (e.g. no unnecessary kinks or compressions). Any grills or filters must be unclogged.
