Which term is used in codes and standards to identify the legal entity with the authority to enforce a code and approve or require equipment?

• A. Inspector
• B. Building Official
• C. Fire Marshal
• D. Authority Having Jurisdiction (AHJ)

Answer: (D)

The concept being tested is the Authority Having Jurisdiction (AHJ). This term names the legal entity empowered to enforce codes and standards and to approve or require equipment. In practice, the AHJ can be a Building Official, a Fire Marshal, or another official or government body designated by the jurisdiction. The Inspector is the person who enforces under the AHJ, while the Building Official or Fire Marshal are common roles that can serve as the AHJ depending on the locality. The key idea is that AHJ is the recognized authority responsible for code enforcement and equipment approval.
