The association's own definition of a code official is a professional providing building and plumbing plan review, field monitoring, or inspections for any types of building construction, which maps directly onto the four content areas this exam is organized around: plumbing code and regulation, plumbing plan review, field inspection and monitoring, and professional practice, ethics and administration.
