A list of what is usually common property is as follows:
- all floors including staircases, emergency stairs, ramps and balconies and associated fittings such as balustrades;
- all structural or load-bearing columns and walls;
- all external doors and windows;
- all electrical and plumbing items that service more than one lot (they may be located inside walls);
- tiles originally attached to a common property surface (eg. the bathroom floor tiles or the wall walls of a toilet inside an apartment);
- timber parquetry and timber floor boards if originally installed;
- all ceilings including vermiculite ceilings, plaster ceilings and cornices;
- all other original floor coverings (eg magnesite finish and layers of topping concrete);
- balcony doors are usually common property (if the strata plan was registered after 1 July 1974);
- internal concrete slab floors dividing apartment floors for multi-storey apartments;
- external concrete slab roofs;
- almost all building membranes eg the waterproofing behind and under bathroom walls and floors;
- damp proof courses; and
- ventilation systems.
Many strata plans contain notations to identify elements as either common property or not. In some cases, specialist advice may be required to determine what is common property or not.
