What is the basis for determining the amount of a condominium owner's monthly assessment for operations and maintenance?

The correct choice for determining a condominium owner's monthly assessment for operations and maintenance is based on the unit's pro rata ownership share as defined in the declaration. This ownership share reflects the portion of the common areas and resources that each unit owner has, which is typically outlined in the condominium's governing documents.

Assessments for operations and maintenance are calculated proportionally, meaning that each owner's share of these costs is directly related to their share of ownership in the condominium. This ensures that the burden of expenses is fairly distributed among all unit owners based on the size and value of their individual units relative to the entire condominium complex.

While factors such as square footage, the total number of units, and the overall budget of the association may influence the budget or total required assessments, they do not directly determine how much each owner pays. It’s the pro rata ownership share that serves as the fundamental basis for these assessments, ensuring an equitable division of costs associated with the upkeep and management of shared property facilities.
