The Shire of Mundaring is largely located within a bushfire prone area. Construction of a new dwelling or additions to an existing residence within a bushfire prone area may require planning approval prior to the lodgement of a building permit application.

Building works valued under $20,000 do not require a registered builder allowing owners to nominate themselves as “builder” on the building application form.

For building works over $20,000 a registered builder must be nominated as the builder. Owners who wish to appoint themselves as the builder for building works over $20,000 are required to attain an owner-builder certificate from the Department of Mines, Industry Regulation and Safety.

Owners who have chosen to do the earthworks in lieu of their builder, must obtain a separate building permit prior to any earthworks commencing.
