Which term describes a structure with walls and a roof designed for housing or support of individuals or property?

The term that best describes a structure with walls and a roof designed for housing or support of individuals or property is a "building." In the context of the Kentucky Plumbing Code and general construction terminology, a building is specifically defined as an enclosed structure that serves a purpose, whether it be residential, commercial, or industrial. This definition encompasses both the protective features of walls and a roof, as well as the function of providing space for people or goods.

While other terms like "facility," "infrastructure," and "construction" might relate to structures in various ways, they do not carry the same precise connotation. A facility often refers to a place built for a specific purpose, which may not necessarily imply a fully enclosed structure with walls and a roof. Infrastructure typically refers to the foundational systems that support services and public works, such as roads and utilities, rather than individual buildings. Construction denotes the process of building or assembling structures, rather than the structures themselves. Thus, a building stands out as the most accurate description for the given definition.
