Find out when you need a Building Permit for a dwelling or property addition and how to apply. Information on solar passive building is also provided here.

Overview of requirements

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 Approval from the Department of Local Government, 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 commencing earthworks.
