What is a BAL assessment and when do you need one?

A BAL assessment determines the level of bushfire exposure for a proposed building or property, setting the construction standards required under Australian Standard 3959. The assessment focuses on the proposed building envelope and how it interacts with the surrounding landscape, including vegetation type and proximity, slope of the land, and potential fuel loads. The resulting BAL rating outlines the construction measures needed for compliance and helps property owners understand their bushfire risk and the precautions required to manage it.

In Southwest Western Australia, most residential properties fall within mapped bushfire-prone areas, meaning a BAL assessment is required before council or a building certifier can approve the build. Samphire Environmental prepares BAL reports compliant with State Planning Policy 3.7 and AS 3959, giving you confidence that your documentation is accurate, complete, and ready for submission the first time.

Ember attack risk. Basic ember protection measures required.

BAL-19

Moderate

Increased ember and radiant heat exposure. Enhanced protection needed.

BAL-29

High

Significant radiant heat and ember exposure. Considerable fire-resistant construction required.

BAL-40

Very high

FAQ

BAL assessment questions, answered

  • A Bushfire Attack Level (BAL) assessment determines the level of bushfire exposure a building will face. It classifies the risk from BAL-LOW through to BAL-FZ (Flame Zone) based on vegetation type, slope, and distance from bushfire-prone vegetation, following Australian Standard AS 3959.

  • You need a BAL assessment if your property is located within a designated bushfire-prone area under your local planning scheme. In WA, properties within bushfire-prone areas require a BAL Assessment prior to building, development or planning permit approvals.

  • BAL assessments from Samphire Environmental typically sit within the $500 to $700 range depending on site complexity and travel distance. We send a quote after reviewing your site details.

  • The site visit runs around one to two hours. We complete your BAL report within three to five business days of the site inspection. Total turnaround from booking to final report depends on scheduling.

  • A BAL assessment sets the Bushfire Attack Level for a specific building site. A Bushfire Management Plan is a broader document that addresses bushfire risk across a whole development and sets mitigation measures. Some projects need both.

  • BAL ratings run from BAL-LOW (no special bushfire construction requirements) through BAL-12.5, BAL-19, BAL-29, BAL-40, and BAL-FZ (Flame Zone). BAL-FZ is the highest rating and carries the strictest construction requirements.

  • Our BAL reports are written to AS 3959 and WA SPP 3.7. Local councils and building certifiers across Southwest Western Australia accept them as part of development and building approvals.

  • We service the Capes and Southwest regions. Get in touch if you are unsure whether your site is inside our coverage area.
