Final answer:
A hospital building is the least likely to be a mixed occupancy compared to residential, office, or retail buildings because of its specific and sensitive function dedicated to health services.
Step-by-step explanation:
The question asks which building type would be the least likely to be a mixed occupancy. A mixed occupancy building is one that is used for more than one purpose, such as residential and commercial. Considering the options provided, a hospital building is the least likely to be a mixed occupancy. Hospitals are generally single-use buildings due to the specific and sensitive nature of the health services they provide. Although there can be support services within a hospital, such as a gift shop or a cafeteria, the primary use of a hospital is distinct and does not typically mix residential, retail, or office spaces within it.
The Multiple Nuclei Model, represented in Figure 11-19, and the image of apartment buildings in a "community needs assessment" suggest that different types of buildings serve various functions and cater to different needs within a community or urban area. While residential, office, and retail buildings often incorporate multiple uses and serve multiple demographic groups, hospitals, due to their specialized function, remain more homogeneous in usage.
