AHJ stands for?

• A. Alarm Handling Jurisdiction
• B. Authorized Health Judge
• C. Authority Having Jurisdiction
• D. Approved Handling Jurisdiction

Answer: (C)

In fire code and plan review, the Authority Having Jurisdiction is the official entity empowered to enforce codes, review plans, issue permits, and approve work. AHJ stands for Authority Having Jurisdiction. This is the organization that determines whether a fire protection system—such as a flammable refrigerant refrigeration system—meets the applicable codes and standards, conducts inspections, and grants final approval for occupancy.

The AHJ can be the local fire department, the building department, or another designated agency, depending on the project and jurisdiction. Their role includes plan review, permit issuance, periodic inspections, acceptance testing, and the final clearance to operate or occupy a building.

Other terms shown don’t reflect the recognized authority in this context—there isn’t a recognized “Alarm Handling Jurisdiction,” “Authorized Health Judge,” or “Approved Handling Jurisdiction” term used for this purpose.
