Which of the following best describes a legal suite?

A legal suite refers to a self-contained living area that meets specific building codes and zoning regulations, often found within a larger residential property, such as a basement. This definition includes key features like having its own entrance, kitchen, bathroom, and living space, which allows it to function independently from the main living area of the home. Legal suites are increasingly popular because they not only provide additional living space but also can serve as rental units, enhancing the owner's ability to generate income.

In contrast, the other options do not accurately capture the essence of a legal suite. A family living arrangement might encompass multiple people living together without the distinct separation or independence inherent in a legal suite. A shared apartment typically implies common areas and shared resources, rather than the full self-containment required for a legal suite. Lastly, a temporary guest room suggests a space intended for short-term use, lacking the permanent, independent setup of a legal suite. Thus, understanding the distinct characteristics of a legal suite is crucial for recognizing its role within residential properties.
