Inspectors suggest changes and check later that they were made. The size and type of structure determine how often the inspector visits. Inspectors generally specialize in one type of construction work. Specialties include electrical, plumbing, and mechanical inspection. Public works inspectors check bridges, highways, streets, and other public structures.
Home inspectors examine a home before it is sold or to determine if repairs are needed.
Inspectors also check permits on home repairs. Although inspections are primarily visual, inspectors often use tools. For example, they use tape measures, survey instruments, and metering devices. They keep a log of their findings and take photographs. Inspectors file reports and meet with construction crews to ask for changes.
