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

Mr. Able owns the air space within his unit, Apt. 22, as his exclusive property. In a condominium arrangement, each unit owner has individual ownership of the air space contained within their specific unit, which means they have the right to occupy and utilize that space without having to share it with other co-owners. This ownership includes the interior walls and any fixtures within the unit.

In contrast, the common areas of the building, such as hallways, recreational facilities, and parking lots, are jointly owned by all the condominium owners. Therefore, Mr. Able does not have exclusive ownership of these areas. The same applies to the exterior walls, which are typically part of the common elements and are shared among all residents. The land beneath the unit is also a common element and not owned individually by Mr. Able. Hence, the air space within Apt. 22 represents the only portion of the condominium that he owns outright and can use without obligations or sharing with other co-owners.
