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
