Massachusetts Construction Supervisor License (CSL) Practice Test

When is an automatic sprinkler system required in one and two-family dwellings?

1. Greater than 14,000 square feet including basements

2. Greater than 14,400 square feet including garages

3. Greater than 14,400 square feet including unfinished attics

4. Greater than one story in height with an attached garage

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

An automatic sprinkler system is required in one and two-family dwellings when the total area exceeds 14,000 square feet, including basements. This requirement is grounded in safety regulations designed to enhance fire protection, especially in larger homes where the risk of fire could result in significant property damage and endanger lives. By specifying that the square footage includes basements, this regulation ensures that all potential living spaces are accounted for in fire safety planning. While the other options mention different square footage thresholds or additional structures like garages and attics, they do not align with the specific regulation governing the installation of sprinkler systems in one and two-family homes. The focus on the total area, including basements, highlights an emphasis on comprehensive coverage that takes into consideration all parts of the dwelling structure. Understanding these requirements is crucial for any construction supervisor to ensure compliance with local codes and enhance overall safety in residential environments.
