Unit title guidance from Quay Law

Common Property and Exclusive Use Areas

Ian Mellett, Barrister and Solicitor, Quay Law

Common property is everything in a unit title development that is not part of a unit. It often includes the land, the structure of the building, the roof, lifts, stairwells, driveways, gardens and shared facilities. It is owned by the body corporate on behalf of all the owners.

What Common Property Is

The unit plan shows what is common property. In an apartment building, it commonly includes the exterior, the structure, foyers, corridors and shared services. In a townhouse development, it may include driveways, paths, landscaping and visitor parking.

Because common property belongs to everyone, no single owner can alter it or use it in a way that excludes others without the body corporate’s approval.

Who Pays for Common Property

The body corporate maintains and repairs common property, funded by levies paid by owners. The cost is generally shared according to utility interest. Different sets of utility interests may apply to particular costs or services.

This shared responsibility is one of the main advantages of a unit title. It is also why the condition of common property, and the body corporate’s plans for it, matter to every owner.

Exclusive Use Areas

An exclusive use area is part of the common property that one owner is given the right to use, to the exclusion of others. Typical examples include a courtyard, a car park or a garden area adjoining a unit.

The owner does not own the area. They have a right to use it, granted by the body corporate. The arrangement may place responsibility for maintenance on the owner who has the use of it, and it may be subject to conditions or be changed by the body corporate.

Alterations Affecting Common Property

Any work that affects common property, such as installing a heat pump unit on an exterior wall, enclosing a balcony or making changes to a courtyard, generally requires body corporate approval. Work carried out without approval may have to be reversed at the owner’s cost.

What Buyers Should Confirm

  • Whether any area you expect to use exclusively is part of your unit or common property.
  • If it is an exclusive use area, how that right was granted and on what terms.
  • Who is responsible for maintaining it.
  • Whether any alterations to common property near the unit were approved.
