When determining the total occupant load of a building, in this case use group B, do you account for corridors or bathrooms when determining the load of each individual space in order to get the total number of occupants?
FLOOR AREA, GROSS. The floor area within the inside perimeter of the exterior walls of the building under consideration, exclusive of vent shafts and courts, without deduction for corridors, stairways, closets, the thickness of interior walls, columns or other features. The floor area of a building, or portion thereof, not provided with surrounding exterior walls shall be the usable area under the horizontal projection of the roof or floor above. The gross floor area shall not include shafts with no openings or interior courts.alacreative said:Can you explain what you mean by that? There are waiting areas and assembly areas within this building as well, so I do need to modify the square footage per occupant calculation for those spaces, correct? So I'm essentially dealing with each space individually when determining the total occupant load?
Does this mean I ignore my Assembly without fixed seats (standing space) areas? The occupant load per floor is determined by its primary function? Not each individual space?FLOOR AREA, GROSS.

Please restate the questionalacreative said:Does this mean I ignore my Assembly without fixed seats (standing space) areas? The occupant load per floor is determined by its primary function? Not each individual space?
I'm dealing with a B use group building that has multiple tenant spaces. So, in turn, this building primarily consists of office space, common lounge areas, common waiting areas, storage areas, common kitchen areas, etc. So, when referring to table 1004.1.1, not all areas of the building are business areas (yes? no?). So I was assuming that there is a different square footage calculation for the office areas in comparison to some of the common areas (such as the storage areas being 1 person/300 sf and the kitchen areas being 1 person/200 sf as opposed to the 1 person/100 sf for all the office spaces). Or, are all areas classified as business areas?cda said:Please restate the questionGive example
I think the answer is no
That is correctSo I was assuming that there is a different square footage calculation for the office areas in comparison to some of the common areas (such as the storage areas being 1 person/300 sf and the kitchen areas being 1 person/200 sf as opposed to the 1 person/100 sf for all the office spaces)
One thing I always found confusing is the connection between the building use group and individual space classification. From my understanding and based on the definition above, Chapter 3 Use and Occupancy Classification, defines not only the building classification, but also individual space classification that can help you understand which conversion to use for table 1004.1.1?hlfireinspector said:303.1.2 Small assembly spaces. The following rooms andspaces shall not be classified as Assembly occupancies:
1. A room or space used for assembly purposes with an
occupant load of less than 50 persons and accessory to
another occupancy shall be classified as a Group B
occupancy or as part of that occupancy.
2. A room or space used for assembly purposes that is less
than 750 square feet (70 m2
) in area and accessory to
another occupancy shall be classified as a Group B
occupancy or as part of that occupancy.
IMO I always think about this, the people in the conference room are almost always the people from the building.
Ahhh, I see.cda said:My shotOccupancy types the building and spaces in it.
Which is different from the occupant load factor table. That just is used to determine the occupant load of a room.
But indirectly can affect the occupancy type as in A and B, once you hit fifty you fall into a different occupancy.
So,
1. sq foot of building and rooms in it
2. Occupant load
3. Occupancy type
