Important note – please read first

All Class 2-9 buildings require planning approval prior to submitting a Building Permit application. 

Certified building permit applications must be submitted complete with all prior approvals issued (including planning approval). 

Find out how to apply for planning approval.

Step 1: Apply for a building permit

Applications for a commercial Building Permit are required to be lodged as a Certified (BA1) application. A Certified application has been assessed by a private Building Surveyor and has been issued with a Certificate of Design Compliance. 

When submitting your application for a Building Permit Certified, you will need to include the following:

  1. Completed BA3 – Certificate of Design Compliance that is signed by a registered building surveyor, including all referenced documents within the Certificate of Design Compliance 
  2. Planning Approval number (if planning approval is required)
  3. Proof of Environmental Health approval if you are installing a sewage effluent system (if required)
  4. Stormwater Drainage Plan – Drainage design must be certified by a practising Civil Engineer or Hydraulic Consultant. 

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
