Can a secondary residence be converted into a dual occupancy?
Yes, potentially. A secondary residence may be converted to form part of a dual occupancy if the property and dwellings meet the applicable multi-unit housing requirements. Development and/or Building Approval may be required.
Yes, potentially. A secondary residence may be converted to form part of a dual occupancy, but simply changing its use or calling it a dual occupancy is not enough.
The property and both dwellings must meet the applicable dual occupancy (multi-unit housing) planning requirements. Depending on the existing buildings and proposed changes, a Development Application and building work may also be required to bring the development into compliance.
If separate ownership or sale is intended, the development would also need to meet the applicable subdivision or unit-title requirements.
