I have seen it done in warehouse space when a tenant constructs offices below. The reason I was given from the AHJ is that if/when the office space is removed the warehouse is easily restored back to the original design criteria. Luckily we knew of this in advance and had a new low system included in our price.

The tenant is dropping in a T-Bar grid ceiling throughout the space. I have the existing piping dropping new pendents to the ceiling and removing the uprights. The AHJ has rejected the plans based on the removal of the uprights citing 8.15.1.2.1 and 8.15.1.2.2 (NFPA 13:2013). His contention is that a T-Bar ceiling is a fully accessible space, and therefore requires sprinkler protection above. Anyone been hit with this before?
