Bushfire Overlay: Development Rules

Bushfire overlays apply to properties in areas identified as having bushfire risk. They affect building standards and design but generally don't prevent development.

What's Required

  • BAL assessment — Bushfire Attack Level determines construction standards
  • Construction standards — AS3959 construction requirements based on BAL rating
  • Defendable space — vegetation management around buildings
  • Access — adequate emergency vehicle access
  • Water supply — firefighting water supply may be required

BAL Ratings

BAL Rating Construction Impact Cost Premium
BAL-LOW Standard construction Nil
BAL-12.5 Minor upgrades 2–5%
BAL-19 Moderate upgrades 5–10%
BAL-29 Significant upgrades 10–15%
BAL-40 Major upgrades 15–25%
BAL-FZ (Flame Zone) Extreme requirements 25%+ or not feasible

Development Impact

Bushfire overlays add construction cost but don't typically prevent development:
- Standard lots: BAL-compliant homes are routine
- Development sites: BAL considerations factored into feasibility
- Insurance: Premiums may be higher in bushfire areas
