With many parts of Western Australia experiencing long dry seasons and dense vegetation, it’s no surprise that bushfire-prone areas are a real consideration for homebuilders. But building in these zones doesn’t mean giving up on your dream home, it just means getting smart, prepared, and working with the right team.
What Is a Bushfire-Prone Area?
A bushfire-prone area is a region identified by the WA Government as having potential exposure to bushfires. These zones are marked on the Map of Bush Fire Prone Areas and are updated annually.
If your block falls within one of these zones, your new home will need to meet specific safety and construction requirements to reduce fire risk, especially if the Bushfire Attack Level (BAL) rating is BAL-12.5 or higher.

What Is a BAL Rating?
BAL (Bushfire Attack Level) is an assessment that determines how much your property might be exposed to ember attack, radiant heat, or direct flame contact during a bushfire. BAL ratings range from:
- BAL-LOW – Very low risk
- BAL-12.5 to BAL-40 – Increasing levels of risk requiring specific construction methods
- BAL-FZ (Flame Zone) – Highest level of risk
Your home design, materials, and construction will need to align with your BAL rating and that may include things like ember-resistant vents, toughened glass, metal mesh screens, and non-combustible materials.

What Changes in the Building Process?
If you’re building in a bushfire-prone area, here’s what to expect:
- BAL Assessment: A professional assessment of your land to determine your BAL rating.
- Design Modifications: Your floorplan or facade may need adjustments to meet BAL requirements.
- Material Choices: You’ll need specific roofing, cladding, and window materials based on your BAL.
- Additional Costs: Higher BAL ratings can add to your build cost, but not always as much as you think.
- Building Approval: You’ll need to submit evidence that your home meets BAL standards when applying for a building permit.
