A building inspector’s primary job responsibilities are to look at public buildings and ensure they are up to federal, state, and local codes. In this job, your duties are to look at the structural integrity, electrical wiring, water connections, and other aspects of the construction and make sure that everything works as it should and complies with all safety regulations. Inspectors have to know a variety of building disciplines and trades, or at least the laws related to them. For example, you have to know basic wiring codes and how to recognize a dangerous situation, such as broken or loose wiring, as well as general building hazards.
