Amenity Area* - a portion of a building that adds a convenience
for the occupants of a floor or building and that is
not used exclusively by any one occupant.
Discussion: Amenîty Areas are relevant in industrial
buildings only when they serve more than one egqypaIJ.
Amenity areas are convertible to occupant area and are
not required by occupancy codes and regulation, although
there may be codes and regulations that relate to their
specific uses. Amenity areas that serve all the occupants
of a buílding are building amenity areas. Amenity areas
that serve only the occupants of a floor are floor amenity
areas. Refer to those definitions for specific examples.
