What part of the condominium does Mr. Able own without sharing with other co-owners?

Mr. Able owns the air space within his condominium unit, Apt. 22, without sharing it with other co-owners because this is a fundamental aspect of condominium ownership. In a condominium, each unit owner has exclusive rights to their individual unit, which includes the living space within the walls of that unit.

This exclusive ownership contrasts sharply with other elements of a condominium property, such as the land the building is on, the common areas (like hallways, roofs, and recreational facilities), or the entire building, which are typically owned collectively by all unit owners. Therefore, while Mr. Able does share ownership over common areas and the land with other residents, the air space within his specific apartment is solely his property. This distinction is essential for understanding the unique nature of condominium ownership in real estate.
