Do I need to finish construction before obtaining separate titles?

Yes. For a dual occupancy, the dwellings generally need to be constructed and have their Certificates of Occupancy and Use before separate unit titles can be approved.

You may be able to lodge the unit title application earlier, but the required completion documents, including the Certificates of Occupancy and Use, must be provided before final approval of the unit titles.
