A part of a building whose floor is closest to ground level or street level. It is generally considered to be the first floor.
The destination of the immovable, of the private portions and of the common portions is a fundamental concept in co-ownerships. It is both a real regulator of the rights and obligations of co-owners and a reference value between the permit and the prohibited. The destination of the building is determined in the 1st part of the declaration of co-ownership (constituting act of co-ownership). It is it that also makes it possible to establish the type of co-ownership established and defines the use(s) that can be made of the private and common portions. It can thus be exclusively commercial or residential or residential but with the possibility of practicing a professional activity. It can also be mixed, such as, allowing shops on the ground floor and apartments on the upper floors.
