If you are thinking about owner-building your own home or small commercial building, valued over $20,000, you are required to apply to the Building Services Board for approval before applying for a building licence or permit from the local government.
As an owner-builder you take on full responsibility as the builder, including the need to comply with building standards and the liability to future owners for building defects. When applying to become an owner-builder, the Building Services Board requires you to demonstrate that you have sufficient knowledge of the duties and responsibilities of an owner-builder before giving approval.
