Final answer:
The occupant load in areas with fixed seating without dividing arms is based on one person for each 18 inches of seating length.
Step-by-step explanation:
The subject of this question is Building Codes.
According to building codes, for areas with fixed seating without dividing arms, the occupant load should be not less than the number of seats based on one person for each 18 inches of seating length. This means that for every 18 inches of seating length, there should be at least one occupant.
For example, if there is a seating area that is 54 inches long, the occupant load for that area would be 3 people (54 inches รท 18 inches = 3 people).
