Common property is all the areas of the land and building not included in any lot. It is jointly owned by all owners and the owners corporation is responsible for its management.
The common property boundaries of each lot are generally formed by:
- the upper surface of the floor (but not including carpet)
- the under surface of the ceiling
- all external or boundary walls (including doors and windows)
The decision to add to or alter common property can only be made by a special resolution at a general meeting.
