Common property is all the areas of land and building not included in any lot. This can include external walls, windows, roof, driveways, foyers, fences, gardens and facilities such as a pool or gymnasium.
It is jointly owned by all owners and the Owners Corporation is responsible for its management.
As an owner, you have responsibilities. Not only do you own your own individual lot, but you share ownership and responsibility of common property with the other owners as well.
