A building is constituted as a Horizontal Property when it is divided into autonomous fractions, provided that they are registered separately, which, in addition to independent units, are distinct and isolated from each other, namely apartments or floors and garages. Each of them may have different owners, and must have its own exit to a common part of the building or to the public road.
Thus, a simple open parking space, usually called a parking space, does not constitute an autonomous unit, although its use may be reserved for an autonomous unit.
