Bush fire assessments
If you plan to build a residential building in a bushfire prone area you will be required to have an assessor determine the intensity of a bushfire attack on your proposed building, known as a Bushfire Attack Level (BAL) assessment. This will then determine the construction requirements appropriate for your proposed building. All buildings proposed in bushfire prone areas need to meet the provisions of Australian Standards 3959 as amended.
Further information on changes to requirements in designated bush fire prone areas in Western Australia, including publications available for download, are available on the Building in designated bush fire prone areas webpage on the Building Commission website. The Map of Bush Fire Prone Areas is available to view on the Department of Fire and Emergency Services website.
