Massachusetts Construction Supervisor License (CSL) Practice Test

What is the minimum required width for a habitable room in a single family dwelling, besides the required area?

1. 5 feet

2. 7 feet

3. 10 feet

4. 8 feet

The correct answer is: 7 feet

For a habitable room in a single-family dwelling, the minimum required width is designed to ensure adequate space for use and circulation within the room. The code specifies that a habitable room must have a minimum dimension of 7 feet. This width is important because it allows for functionality in various living activities, such as placing furniture, moving around safely, and providing a comfortable living environment. Having a minimum width of 7 feet ensures that the room is not just physically adequate but also meets safety and comfort standards. This specification aids in creating spaces that are not only usable but also comply with the building codes, which ultimately enhance the quality of living and the safety of the occupants. Selecting a width smaller than this would compromise the usability of the room, leading to potentially overcrowded or awkward living conditions.
