What is meant by "common elements?"

Common elements refers to all property within a condominium that has not been defined and set up by the declaration and description as part of the units. Along with owning the condo unit, the title holder also becomes a tenant-in-common with the other unit owners of the common elements. Unit owners may make reasonable use of the common elements subject to the condominium's declaration, by-laws and rules.

Please note that not all common elements are the same, as areas designated as common elements in one condominium might not be designated as so in another. For example, the distinction of whether the exterior walls of a unit are considered common elements differs by condominium.
