The Bushfire Management Overlay (BMO) has simple bushfire protection requirements for outbuildings including planning permit exemptions and streamlined assessment processes for certain types of outbuildings.

Exempt outbuildings

Outbuildings with a floor area of less than 100 square metres do not require a planning permit under the Bushfire Management Overlay.

You should check with your council as other planning controls may apply.

Outbuildings with a floor area of 100 square metres or more associated with and normal to a dwelling

Outbuildings with a floor area of 100 square metres or more have preset bushfire protection measures for defendable space and fire separation construction (where required) to make preparation and assessment of these types of applications simpler.

These types of outbuildings must:

  • Have a floor area of 100 square metres or more.
  • Not be used for accommodation.
  • Be associated with and normal to a dwelling. (Note large outbuildings may not be considered to meet this test).

All the above requirements must be met or the outbuildings will be assessed as Other Outbuildings.

The preset bushfire protection measures mean an application will not need to include individual Bushfire Attack Level (BAL) assessments, a bushfire management statement or be referred to the CFA.

Other Outbuildings

Other outbuildings will be assessed through the regular BMO process.
