Questions & Answers

Can I keep my existing dwelling and add a second dwelling without subdivision

Yes. You can potentially keep your current house and build another home on the same block without splitting the land into separate blocks. If you want each home to have its own ownership, you may need to create unit titles after construction.

Short Answer

Yes. You can keep your existing dwelling and add a second dwelling without subdividing the block. Separate ownership may require unit titling after construction.

Detailed Explanation

Yes. You may be able to retain your existing dwelling and add a second dwelling without undertaking a block subdivision. In this case, both dwellings would remain on the same Crown lease. If separate ownership is intended, a unit title subdivision may be considered after the dwellings are constructed and the relevant requirements are met.

Key Point

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