1004.5 Areas without fixed seating. The number of occupants
shall be computed at the rate of one occupant per unit of
area as prescribed in Table 1004.5. For areas without fixed
seating, the occupant load shall be not less than that number
determined by dividing the floor area under consideration by
the occupant load factor assigned to the function of the space
as set forth in Table 1004.5. Where an intended function is not
listed in Table 1004.5, the building official shall establish a
function based on a listed function that most nearly resembles
the intended function.

Where an intended function is not
listed in Table 1004.5, the building official shall establish a
function based on a listed function that most nearly resembles
the intended function.
BUILDING. Any structure utilized or intended for
supporting or sheltering any occupancy.
