Which of the following would not be considered a common expense assessment?

In the context of common expense assessments within a homeowners' association or a condominium association, common expenses are those costs that benefit all unit owners and are typically shared among them. Items such as the maintenance of the community pool, landscaping for shared areas, and repairs for the building structure are all considered common expenses because they contribute to the upkeep and overall function of shared community assets.

On the other hand, a unit owner's patio furniture is a personal item and is specific to an individual unit rather than a shared community asset. This means that the cost associated with purchasing or maintaining patio furniture is the responsibility of the individual owner and does not benefit or affect the entire community. Therefore, it wouldn't be included in common expense assessments, making it the correct answer.
