Massachusetts Unrestricted Construction Supervisor License Practice Test

An automatic sprinkler system is required in all one and two family dwellings greater than which of the following square feet?

1. 14,000 square feet including basements

2. 14,400 square feet including garages

3. 14,400 square feet including unfinished attics

4. One story in height with an attached garage

The correct answer is: 14,000 square feet including basements

An automatic sprinkler system is mandated in one and two-family dwellings when their total area exceeds 14,000 square feet, including basements. This requirement is put in place to enhance fire safety and control, particularly due to the larger volume of space that could pose a greater risk during a fire emergency. By specifying that the square footage includes basements, it acknowledges that these areas can significantly contribute to the total area of the dwelling, thus impacting the overall safety measures required. Therefore, the correct choice emphasizes the importance of considering the full extent of the building's footprint, including any lower levels where occupants might be located during a fire event. The incorrect options may misinterpret the regulations by either exceeding the threshold unnecessarily or by not including essential areas such as basements or unfinished attics, which can also be utilized for living or storage purposes. Thus, awareness of these guidelines is vital for construction supervisors working to meet safety requirements in residential construction.
