Massachusetts Unrestricted Construction Supervisor License Practice Test

Which of the following use groups does NOT require a sprinkler system?

1. A-1

2. B, with 12,000 square feet floor area

3. C, M (all uses) in a four story building

4. D, S-1, 11,500 square feet in a 3 story building

The correct answer is: B, with 12,000 square feet floor area

Buildings designated as Group B (Business Occupancies) often have specific criteria that dictate whether a sprinkler system is necessary based on the size and configuration of the structure. In Massachusetts, a Group B occupancy does not require a sprinkler system if the building floor area does not exceed certain thresholds—in this case, 12,000 square feet is specified. In contrast, Group A-1 (Assembly Occupancies) is generally required to have sprinklers due to the high occupancy loads and potential fire hazards associated with such buildings. The same applies to Group C (Residential), when combined with Group M (Mercantile) in structures of four stories; these types of buildings usually necessitate sprinklers for safety and code compliance. Understanding these classifications and their requirements is essential for ensuring compliance with local building codes and maintaining safety standards.
