Ok let see if I can write this correctly. Commercial masonry building, entry land with stairs that go down 5 risers, second set of stairs to the left head up to a mezzanine. Stairs and landing wood construction with no 1 hour requirements. All plywood 5/8". Stairs to mezz is walled from floor to roof all drywall is 5/8 X GWB, other side of stair is masonry. Non-accessible concealed area created under all stairs and landing protected by again 5/8 X GWB on one side with masonry on the other.
FMO had the contractor cut an opening to get mezz and required the inside of this to be drywalled according to NFPA 13. FMO says both sides of a non-accessible concealed area must be drywalled. I think he is misunderstanding this requirement in NFPA 13 or I am as well as the plans examiner missing something as just do not understand his thinking.
Please shed light (not fire) on this so I can see clearer. Thanks much everyone
