It depends on where that opening is located. If you plan on separating the Group B area from the Group S-2 area with a 2-hour fire barrier, then any opening in that fire barrier must have a 1-1/2-hour rating.Yes, the office is framed out inside, thus it does not go all the way to the ceiling. The wheels of course are not combustible -- just wheels. I also have an area where we work out and roll stuff in and out that has a wall unit on it, and it has the hanging meat locker like plastic strips. Does this also have to have the 2 hour barrier? It is kind of crazy as I really do not see the purpose of the barrier. Everyone can walk from their office to the front door in under 5-10 seconds!!
Does your building have at least 20-foot open spaces all around the perimeter? If so, you can get a 50% increase for frontage; thus, increasing your allowable area to 13,500 sq. ft. for a nonseparated Group B building.
