A building inspector is an individual who is qualified to inspect both domestic and commercial structures. This is actioned to ensure they comply with the necessary standards and regulations, and the original building plan. It is also their job to verify the workmanship of the builder or tradesperson and to identify any defects, if any. While regulations differ from state to state, Australia as a whole has a very strict set of standards that all builders and contractors are expected to adhere to. Failure to do so can result in consequences for the individual responsible.

A building inspection can be carried out prior, during and after a structure has been built and is sometimes done at random to ensure builders are complying with the correct standards. Commercial structures in particular are typically always subjected to a thorough building inspection to ensure safety.
