Frequently asked questions

Q: How do I know what standard my house has to be built to if I am in a bush fire zone?
A: If your property is on fire prone land in NSW or in the buffer zone you will need to meet the requirements outlined in the Australian Standard AS 3959 Construction of buildings in bushfire-prone areas as well as Planning for bush fire protection Addendum Appendix 3. There are six construction levels in the Standard, based on the Bushfire Attack Level (BAL) of the property. They are BAL – Low (no specific construction requirements) BAL -12.5, BAL 19, BAL 29, BAL 40 and BAL – FZ (Flame Zone – the highest level of construction requirements). For more information see building construction and design and Planning for bush fire protection Addendum Appendix 3and on the Rural Fire Service website.
Q: What is the BAL rating based on?
A: The Bushfire Attack Level (BAL) is based on the type of vegetation, how close the proposed building is to the vegetation, the slope and the fire danger index. Each of these elements has been proven to affect the radiant heat a building is exposed to. The BAL rating to indicate level of risk was introduced in 2009 when the most recent version of Australian Standard AS3959 Construction of buildings in bushfire prone areas was issued.
Q: I have limited budget – what should I spend my money on?
A: Look for measures that have benefits for multiple hazards that you may be exposed to. For example, shutters on windows are effective for ember attack and reducing direct heat exposure in a bushfire; provide protection from debris during storms; and reduce heat entering the house during heatwaves. Other adaptations that have benefits against multiple hazards include rainwater tanks, landscaping (design and plant selection), backup power supply and fire retardant insulation. The cheapest measures are a multi-hazard plan (that everyone in the household knows), access to weather warnings and effective communication within your local neighbourhood.
