Dwellings and Additions

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.

Step 1: Apply for a building permit

You will need to complete a Application for building permit – uncertified (BA2).

Ensure you include: 

  • Architectural drawings including:
    • Site plan
    • Floor plan
    • Elevations
    • Sections
    • Electrical plans
  • Energy Efficiency Report
  • Site classification - issued or certified by a geotechnical engineer
  • Engineering - all structural and construction details designed and certified by a registered structural engineer
  • BAL construction specifications and Bushfire Attack Level (BAL) Assessment and Certificate (if located in a bushfire prone area)
  • Termite management details
  • General specifications
  • Home Indemnity Insurance (for residential works valued over $20,000)
  • Stormwater Drainage Plan.

Refer to Building Permit Fee and Calculator.

Step 2: Assessment

Building permit applications either certified or uncertified are usually assessed and approved within 10 business days.

Building permits are sent to the builder via post.

Step 3: Submit a Notice of Completion

Under the Building Act 2011, the builder must notify the Shire that the work is completed by submitting a BA7 Notice of Completion Form.
