Unit title guidance from Quay Law

Ownership Interest and Utility Interest Explained

Ian Mellett, Barrister and Solicitor, Quay Law

Principal units have an ownership interest and a utility interest. Ownership interest affects voting on a poll and certain ownership rights. Utility interest generally determines contributions to body corporate levies. Checking both helps you understand your obligations.

Ownership Interest

Ownership interest is assessed by a registered valuer when the unit plan is deposited, and it is recorded on the plan. It reflects the relative value of each unit within the development.

Ownership interest is used to determine:

  • Certain ownership rights in common property and the treatment of proceeds when a unit plan is cancelled.
  • Voting entitlements where a vote is taken on a poll.
  • Other rights and obligations for which the Unit Titles Act uses ownership interest.

A larger or more valuable unit will generally carry a higher ownership interest. Its share of levies depends on the utility interests that apply.

Utility Interest

Utility interest is the basis generally used to allocate body corporate levies. It initially equals ownership interest, but may be reassessed under the Act. Different sets can allocate particular expenses according to how owners use or benefit from a service.

Since 9 May 2023, bodies corporate have been able to use multiple sets of utility interests for different costs. A common example is lift maintenance, where owners of ground floor units who do not use the lift may contribute less, or nothing, towards its cost.

Reassessment

Ownership and utility interests can be reassessed in certain circumstances, following the procedures set out in the Unit Titles Act 2010. Reassessment can change the share of costs borne by each owner, so proposals to reassess should be considered carefully.

Why It Matters to Buyers

Before buying, we recommend checking:

  • The ownership interest of the unit you are buying.
  • The utility interests recorded for the unit, including any different sets applying to particular costs.
  • Whether any reassessment is proposed or under discussion.

Two similar units in different developments can carry very different levy obligations depending on how these interests are set.
