"Does anyone know if this is an actual standards requirement or just a preference of the local AHJ ?"
One way to do this would be to ask the AHJ. This is something AHJ's are supposed to know. It is unusual for an AHJ to put himself/herself in the middle between yourself and the building owner by dictating building code requirements. It is actually the Owner's responsibility (with advice from the design professional's team) to figure this out. However, you are being given some good advice by others regarding the process involved. The IBC, along with ASCE 7, will provide the basis for the SDC C advice and there could be a state or local code amendment which supplements the IBC. Being your project is in NC it's likely the IBC is used, but there could be other jurisdictions where there is no adopted code or else it isn't the IBC or a current edition of the IBC.

I am making modifications to a 1970's sprinkler system in NC, we are using the 2000 ed of NFPA 13. There is no seismic bracing on this system. I have had to add some new main in various areas. The local AHJ is requiring that only the new sprinkler main will need to be braced. Does anyone know if this is an actual standards requirement or just a preference of the local AHJ ? Obviously I am trying to avoid installing the seismic bracing on this project. Stephen J.
