Which term describes a self-contained unit used as a home for one or more households?

The term that describes a self-contained unit used as a home for one or more households is "dwelling." A dwelling is specifically designed and used for permanent residential purposes, encompassing single-family homes, apartments, and multi-family residences. By focusing on the nature and function of a dwelling, it encompasses not only the physical structure but also the concept of providing living accommodations for occupants.

When considering the other terms, while "residential property" refers broadly to any land where people live, including the legal and ownership aspects, it is not exclusively about the physical unit itself. "Living facility" typically implies a broader category that could include assisted living or nursing homes, which may not be self-contained units in the traditional sense. "Home structure" is somewhat vague, as it could refer to any physical structure affiliated with housing but does not specifically denote a unit for multiple households or a focus on residential use. Therefore, "dwelling" is the precise term that accurately describes the intended self-contained living unit.
