What characterizes a dwelling unit?

A dwelling unit is characterized as a single unit that provides complete, independent living facilities. This definition encompasses essential features such as having designated areas for sleeping, cooking, and sanitation, which allows individuals or families to live and function independently within their own space. The independent living aspect is crucial; it indicates that the unit is self-contained, meaning it has its own facilities that are adequate for everyday living without reliance on shared or external resources for basic needs.

In contrast, other options describe conditions that don't align with the definition of a dwelling unit. For example, a unit with partial living facilities would lack full independence, which is essential for a dwelling. A facility serving multiple families typically refers to a multi-unit structure, such as an apartment complex, which does not meet the criteria of being a separate, independent unit. Lastly, a unit primarily for storage does not provide living facilities at all, thus cannot be classified as a dwelling unit.
