It would seem that the AHJ has become confused by the verbiage of NFPA 13, 24.1.2.3 (2010 ED) not requiring Hydrostatic testing for modifications to fewer than 20 sprinklers. Call me simple, but the scope of NFPA 25 as outlined in 1.1 (2008 ED) seems pretty transparent as to WHAT must be inspected.

The number '20' has been bandied around for years as to adding that number of heads to an existing system, plans submittals, whether a hydro was required, FDC requirement, etc. In my professional (albeit humble) opinion, ALL fire sprinkler systems need to be inspected/tested per NFPA-25 guidelines. I rather suspect our friends in the insurance industry would concur. In New Mexico, it is quarterly - it is statewide (commercial systems).
