Definition : Common portion

Portions of the buildings and land owned by all the co-owners and which serves for their common use or for the use of some of them (common portion for restricted use). The declaration of co-ownership (description of the fractions) determines what is common. The law lists the facilities which, in the absence of provisions to the contrary set out in the declaration of co-ownership, are presumed to be a common portion: the ground, yards, verandas or balconies, parks and gardens, access ways, staircases and elevators, passage ways and halls, common service areas, parking and storage areas, basements, foundations and main walls of buildings, and common equipment and apparatus, such as central heating and air conditioning systems and the piping and wiring, including that which runs through private portions.
