Questions & Answers

Does my Crown lease allow two dwellings on the block?

Whether you can build a second dwelling depends on what your Crown lease allows and the current ACT planning rules.

Your Crown lease contains conditions that specify how the land can be used and may limit the number or type of dwellings permitted on the block. If your lease does not currently allow the proposed second dwelling, you may need to apply for a Crown lease variation, which could involve additional approvals, requirements and costs.

We recommend checking your Crown lease and the relevant planning requirements before designing or proceeding with a second dwelling.

Short Answer

It depends on the purpose clause and conditions of your Crown lease. Some leases permit more than one dwelling, while others may require a lease variation before a second dwelling can be approved.

Your Crown lease should be reviewed together with the current Territory Plan requirements to confirm whether the proposed second dwelling is permitted.

Detailed Explanation

The ability to construct a second dwelling depends on the purpose clause and other relevant provisions contained in the Crown lease for the block, as well as the applicable Territory Plan requirements.

Where the existing Crown lease does not authorise the proposed residential use or number of dwellings, a variation of the Crown lease may be required as part of the development process. A lease variation may also have other statutory and financial implications depending on the circumstances.

Accordingly, the Crown lease and applicable planning controls should be reviewed before proceeding with the design of a second dwelling.

Key Point

No minimum block size does not remove the need for planning assessment.
