Which statement about AHJ approval for NFPA 96/17A installations is correct?

• A. AHJ approval is optional for NFPA 96/17A installations.
• B. AHJ approval is not required in most jurisdictions.
• C. AHJ approval is not involved in NFPA 96/17A installations.
• D. AHJ approval is required for NFPA 96/17A installations.

Answer: (D)

AHJ approval is required to ensure the installation meets the locally adopted codes and standards, and to obtain the necessary permits and final acceptance. The Authority Having Jurisdiction (often the fire marshal or building department) reviews your design, checks that it complies with NFPA 96/17A and local regulations, issues permits, and conducts inspections during and after installation. Even if the design follows NFPA guidelines, you must secure AHJ approval to operate legally and safely, because the AHJ enforces code compliance and grants final acceptance. In many jurisdictions, skipping this step can lead to penalties, required alterations, or denial of occupancy until the system passes inspection.
