The Victorian Government has released maps identifying areas of risk in bushfire-prone areas, which will be used for issuing building permits.

Bushfire Response (and Emergency Services) Minister Peter Ryan says the mapping system will ensure that homes built in bushfire-prone areas will have a minimum level of protection.

The maps will enable a more targeted approach to managing risk by ensuring that only people building in areas of designated risk are required to conduct a bushfire attack level assessment, which they will need in order to get a building permit.

Previously the assessments were required on every new dwelling in the state.
