Thank you sir Travis, I'll call the AHJ to see what he wants for the corridors.

The 2016 edition of 13R (maybe the 2013 edition) has incorporated that. I remember an informal interp from either AFSA or NFSA that stated with the corridor open on both ends, then it was open and did not need sprinklers. However, I have run into many AHJs that interpret it to mean open to sky above. So if you look up and see structure, they want sprinklers.

I'm checking over some plans of a (3) story apartment building, on the 2nd & 3rd floor there is a hallway down the center length of the building with apartments on both sides. The plan shows sidewall heads down the length of the corridor but both ends are open to the outside, are these heads really needed? While I'm at it what about the attached balconies on the back of each unit? I guess what exactly does "open & attached..." mean? Brian Harris, CET BVS Systems Inc.
