Building Frequently Asked Questions
A BAL is a Bushfire Attack Level. This is an assessment made on a particular property with reference to the topography, vegetation type and spread and distance from a proposed dwelling to any vegetation.
A BAL is the expected amount of heat that will impact the proposed dwelling in the event of a bushfire and is expressed as values of Low, 12.5, 19, 29, 40 or Flame Zone.
The BAL will influence the method and materials used to construct the proposed dwelling to ensure construction is in accordance with AS3959-2009 Building in a bushfire prone area.
Council will only accept BAL Assessment reports that are prepared by a suitably qualified, competent person. Please contact Council for further advice.

- Rural or rural residential zones: The Southern Downs Planning Scheme (PDF 8.4MB) determines the setbacks for dwellings;
- Residential and township zones: The Queensland Development Code MP 1.2 Design and Siting Standard for Single Detached Housing determine the setbacks, and are generally 6 metres from the front boundary and 1.5 metres from the side and rear boundaries.
Council has made resolutions declaring that the above types of buildings may have an adverse effect on the amenity of the locality or be in conflict with the character of the locality.
If any of the listed types of buildings are proposed, Council acts as a concurrence agency and may require certain conditions to be complied with prior to granting approval for the building to be erected.
A completed application form, together with the current fee should be lodged together with the appropriate plans to make an application.
Please check the Building Approvals section.
Wind ratings are achieved using a number of calculations, set out in AS/NZS1170.2 Structural Design Actions Part 2 Wind Actions based on factors such as the terrain, shielding on the property and the location and orientation and height of the proposed structure.
Wind ratings are not available from Council for specific plots of land in the Southern Downs region, therefore customers are advised to refer to a structural engineer for a specific wind rating.
The Building Regulation 2006 Schedules 1 & 2 details what building work is not subject to a building approval (self-assessable).
Although an approval is not required, the owner is still responsible to ensure that the work complies with the relevant codes and standards and is safe and fit for purpose.
