Can I retain my existing house and create a dual occupancy?
Yes, potentially. You may retain your existing house and add a second dwelling to create a dual occupancy, provided the overall development meets the applicable planning requirements.
Yes, potentially. The ACT Missing Middle Housing Design Guide specifically illustrates dual occupancy development where the existing dwelling is retained and a second dwelling is added. The completed development must still comply with the applicable Residential Zones Policy requirements, including site coverage, setbacks, private open space, planting, parking and access.
