Which of the following is an example of an incidental occupancy?

An example of incidental occupancy refers to a situation where a particular use of a space is secondary or minor in relation to the primary use of the property. In this context, a private school operating from a home represents an incidental occupancy because the primary function of the property is residential, while the operation of the school is a secondary activity taking place within that residential setting.

This distinction is important as it illustrates how zoning laws and building codes can accommodate diverse activities within a primary use, provided that the secondary use does not interfere with the primary function or violate relevant regulations. The operation of a private school in a home context highlights this principle effectively, as it allows for educational activities without overshadowing the residential nature of the property.

In contrast, the other choices represent primary business uses rather than incidental ones. For instance, a retail store in a mall is primarily commercial, as is a factory in a commercial district and a large office building. Each of these examples serves a main purpose that dominates the use of the space, making them unsuitable illustrations of incidental occupancy.
