If it is a cavity in the wall and the only access is through a removable panel, we call it a concealed space.
As for LSC and closets. IF both the LSC and IBC are applicable, what happens when you have two codes with differing requirements. You take the most conservative of the two. So if BOTH codes require sprinklers and the IBC say follow 13 (no closet exception), then fully follow 13. If ONLY The LSC requires sprinklers then the driving code allows the exception.
