What period of time must inspection records be maintained?

• A. 5 years
• B. 7 years
• C. 10 years
• D. 3 years

Answer: (B)

Maintaining inspection records for a sufficient period ensures there is a complete history of inspections, tests, and maintenance to reference during audits, investigations, or when renewing permits. The seven-year retention window provides enough time to review multiple inspection cycles and track long-term compliance without creating unnecessary administrative burden.

Choosing seven years over shorter periods reflects the need to have a durable trail of fire protection system activity, which can be important for regulatory review, emergency claims, and ensuring any past issues were resolved. Shorter periods, like five years or three years, may miss earlier inspections or trends, while a longer period, such as ten years, can be more cumbersome than needed for routine follow-up.

So, seven years is the standard retention period for inspection records in this context, balancing accessibility of history with practicality. Always check the local AHJ if there are any site-specific requirements, but seven years is the expected answer here.
