Who approves NFPA 20 installations for code compliance?

• A. Authority Having Jurisdiction (AHJ)
• B. Building Architect
• C. Maintenance Supervisor
• D. Insurance Underwriter

Answer: (A)

Approval for NFPA 20 installations comes from the Authority Having Jurisdiction (AHJ). This official entity—the local fire marshal, building department, or other designated authority—enforces fire and building codes in the area. They review the fire pump system design and installation for conformance with NFPA 20 and local amendments, issue permits, perform inspections, and conduct acceptance testing. Only after the AHJ signs off is the project deemed code-compliant and ready for operation. The architect may design the system, but code compliance approval rests with the AHJ; maintenance supervisors handle ongoing operation, and insurers assess risk, not compliance approvals.
