I am calculating a multi-story office building which has handicap accessible toilet rooms added adjacent to the original core. They are located at the end of where a typical multi-tenant corridors would be. Should I allocate space on the corridor side to Floor Common Area since it would be needed access the toilet room? (perhaps 3 feet, based upon door swing)

I normally include the entry area to the toilet rooms in Floor Common Area when they are recessed into the building core, even when they are not enclosed by walls (similar to the way a tenant's recessed entry is assigned to their usable square footage).

Thanks in advance for your help.
