This may seem an obvious question, but no formal qualifications are required in South Australia to carry out an inspection of a building. That means that everyone can call themselves “building inspectors” by having a business card. Take the time to ask your inspector about the industry .A typical construction inspector is a licenced builder, and knows how to build a sound home. All registered builders are required to provide you with this information and to assign a licence number. You can check their registration details if you have any doubts about their credibility.
