Checklist for Building Permit Application (Outbuildings)

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. For further information please refer to Department of Mines, Industry, Regulation and Safety.

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.
