Authorities in WA have introduced building regulations restricting the use of combustible material on high-risk property facades.

The rules require cladding to comply with new Building Code of Australia (BCA) verification methods, meaning builders must show the product has passed a large-scale fire test or has received approval from the Building Commissioner. They also mandate sprinklers in high-risk buildings.

Acting Commerce and Industrial Relations Minister Francis Logan says the amendments close any opportunity for developers to get around BCA non-combustibility requirements.

“The changes will give Western Australians confidence and peace of mind that the cladding of the buildings they occupy is safe,” he said.
