I believe the general consensus the last time this was asked was that the requirement you quoted pertained to the hanger not the structure as specifying building requirements would be beyond the scope of NFPA 13.

Section 9.1.1.2 (2002) says that the the hangers shall be designed to support the water filled pipe plus 250#. Does the structure itself need to support that much, or just the hanger assembly itself.
