What is the maximum occupant load for an existing two-story assembly occupancy of type II construction with a sprinkler system?

The maximum occupant load for an existing two-story assembly occupancy of type II construction with a sprinkler system is calculated using various factors including the building's use, occupancy type, exit access configuration, and applicable codes and standards. For assembly occupancies equipped with a sprinkler system, the occupant load generally increases compared to unsprinklered conditions due to increased life safety considerations.

In determining the maximum occupant load, the International Building Code (IBC) and NFPA codes often provide specific occupant load factors based on the nature of the assembly use (e.g., assembly without fixed seats, assembly with fixed seats, etc.). Each occupancy type has specific factors assigned, which also depend on whether the space is equipped with a sprinkler system.

For type II construction, which is non-combustible but still has some limitations, and with the provisions offered by a sprinkler system, typically, the calculated maximum occupant load for an assembly area is more generous than that for unsprinklered spaces. This is reflected in the numbers corresponding to each option given.

In this case, the highest number offered, which is 300, is justified because it corresponds to the general allowances found in the code for type II assembly spaces with sprinklers, accommodating for factors like the design and
