Building Permit Application

Residential Dwelling or Addition

1. Forms and Supporting Documents 

  • Building Permit Application form; either a certified BA1 form or an uncertified BA2 form. 
    Certified means you have engaged a private Building Surveyor to complete the relevant certificates,
    uncertified means the Local Authority Building Surveyor will assess and complete the relevant certificates.
    The duty of the Building Surveyor is to ensure compliance with the relevant building standards, legislative
    requirements, and town planning matters. See link for forms:
  • The Pro Forma Statement on Planning. For most building proposals, a planning approval will be required before
    a building permit can be issued. The pro forma is designed to ensure planning is addressed prior to the lodgement
    of a Building Permit Application, which will in turn assist in the timely processing of the building application. 
  • Water Corporation Approval Stamp
  • BA20 or BA20A Form for adjoining property owner's consent where works are proposed that will affect adjoining land.
    For information go to WA Building Commission website:
  • Approval to Construct or Install an Apparatus for Effluent Disposal (un-sewered areas only).
