Which of the following is NOT an example of Assembly occupancy?

Assembly occupancy refers to buildings or spaces designed for the gathering of people for entertainment, social, or recreational purposes. Common examples include art galleries, skating rinks, theaters, and similar venues where individuals come together to engage in an activity.

Detention centers, while they do house groups of people, are classified under institutional occupancies rather than assembly occupancies. This distinction is due to their primary function being containment for security and rehabilitation, rather than mere assembly or recreation.

Nursing homes are categorized under residential care or healthcare facilities and do not fall under the assembly occupancy classification either, as their purpose relates to providing living quarters and medical care rather than facilitating public assembly. Thus, both detention centers and nursing homes are not typical examples of assembly occupancy, reinforcing the choice of detention centers as the correct answer, as they specifically highlight the institutional nature of those spaces.
