How is a "Single detached" dwelling unit characterized in subdivisions?

A "Single detached" dwelling unit is characterized primarily by being a standalone structure that is typically surrounded by yards. This means that the dwelling is not attached to any other living units, which allows for a buffer of open space or yard area around it. This separation fosters privacy for the occupants and enables outdoor space for personal use, such as gardens, patios, or play areas.

In contrast, other options describe characteristics that are not associated with single detached units. Being connected to another dwelling refers to townhouses or duplexes, which do not offer the singular separation that characterizes detached units. A multi-story structure can apply to a variety of dwelling types, including apartments or multi-family homes, but it does not inherently define a single detached home. Lastly, being separated by roadways could describe various forms of residential layouts but does not pertain specifically to the nature of a single detached dwelling unit characterized by its standalone presence.
