Given: A health club contains a 1,000-sq.

The occupant load of a space is determined using the 2021 International Building Code (IBC), Table 1004.5 – Maximum Floor Area Per Occupant.

IBC Table 1004.5 – Occupant Load Factor for Exercise Rooms:

The occupant load factor for an exercise room is 1 person per 20 square feet.

Given that the exercise room is 1,000 sq. ft.:

1,000 sq. ft. ÷ 20 sq. ft. per person = 50 occupants

Why Other Options Are Incorrect?

A. 10 – Would require a 100 sq. ft. per person load factor, which is not applicable for exercise rooms.

B. 20 – Incorrect calculation; using the correct load factor, the actual number is 50.

C. 30 – Also incorrect based on the proper load factor.

✅ Correct Answer: D. 50
