In a building defects inspection, a government-appointed inspector checks the status of the house if it is safe to live in.
Being an inspector requires a license, so you are sure to be in good hands. They are trained to look for defects in different parts of the house, including with the plumbing and electricals.
Doing a building defects inspection can help in lots of ways. It is a legal and transparent proof that the house is safe or there is a defect. So, if someone contests if there’s a defect or not, you can just show them the building defects report.
