Questions & Answers

Does my existing dwelling affect whether my RZ1 property can be subdivided?

Yes. Your existing house can affect how your RZ1 property can be subdivided. If you are creating new blocks, each block must be suitable for a future home. If you want separate unit titles, the homes generally need to be built first before they can be separately titled.

Short Answer

Yes. The existing dwelling on an RZ1 property may affect the subdivision pathway and requirements. For a block subdivision, the proposal must demonstrate that the resulting blocks can support compliant dwellings. For a unit title subdivision, the existing dwelling and any additional dwellings generally need to be constructed before separate unit titles can be created.
