Those who carry out building confirmation and inspection in the private institutions are required to have the qualification equivalent to building officials. In 2014, approximately 4 500 people, including public building officials and private inspectors, were engaged. Private institutions accounted for 86% of building confirmations (in 2014) and 80% of final inspections (in 2013). The final inspection rate increased from the 40% in 1998 to about 90% in 2013. The new system also allowed public building officials to focus on conducting other important tasks such as auditing building officials and remedying non-conforming buildings.
