Can I sell one dwelling and keep the other?

Yes, if the dwellings have separate registered titles. If your dual occupancy has been successfully unit titled, you can generally sell one dwelling and keep ownership of the other.

If the dual occupancy remains on one title, the individual dwellings cannot generally be sold separately because they are still part of the same titled property.

Any shared areas, such as a common driveway, remain subject to the registered Units Plan and owners corporation arrangements.
