Are Annex materials mandatory in NFPA 72?

• A. Sometimes
• B. True
• C. False
• D. Not applicable

Answer: (C)

Annex materials are informational and not mandatory. In NFPA 72, the requirements you must follow come from the main body of the standard. Annexes provide background, guidance, examples, and context to help you understand and apply the code, but they do not impose additional obligations unless the annex is explicitly designated as normative or is referenced by the main text. So, you don’t have to follow annex content unless the standard or the adopting authority specifically makes it binding. If in doubt, check how the AHJ has adopted NFPA 72 in your jurisdiction.
