Canberra is witnessing a significant shift in residential planning rules, allowing more landowners to divide their blocks into dual-occupancy housing, ultimately increasing housing options and affordability. The key points of these changes include:
Owners of residential blocks that are 800 square meters or larger will now have the opportunity to split their blocks into dual-occupancy properties. One of the two dwellings will be limited to 120 square meters of floor space, making it more accessible and affordable for potential homeowners. Approximately 45,000 blocks in Canberra may be eligible for this policy change, with a significant concentration in the Tuggeranong and Belconnen districts.
ACT Government Wants More Homes in RZ1
The ACT government's objective is to stimulate the creation of more homes in existing suburbs while enhancing affordability. However, it's important to note that these changes apply only to blocks where secondary dwellings are already permitted.
Under the new Territory Plan, which serves as the central planning document for the ACT, residential zone 1 (RZ1) blocks measuring 800 square meters or more will be eligible for the construction of two homes. According to ABC News, RZ1 blocks are the most prevalent in Canberra, constituting approximately 73% of all zoning types, primarily designed for single, detached houses.
Previously, owners of larger RZ1 blocks could build a secondary residence with a maximum floor space of 90 square meters, but they couldn't subdivide the block into two separate titles for resale. With the new policy, formal subdivision is allowed, with each block obtaining an independent title, and the secondary dwelling's floor space is extended to 120 square meters.
Additionally, the government has introduced new regulations ensuring that an adequate number of trees are planted on these blocks to contribute to the expansion of Canberra's urban forest.
ACT land data suggests that almost 45,000 blocks meet the eligibility criteria for these changes, primarily concentrated in the Tuggeranong and Belconnen districts. Certain suburbs, including Forrest, O'Malley, Weetangera, and Turner, have a high proportion of RZ1 blocks that are large enough to qualify for the new dual-occupancy rules, offering homeowners an opportunity to make the most of this policy shift.

Are you considering adding a Granny Flat to your property in rural or regional New South Wales? The Inland Code does not permit complying development for the erection of secondary dwellings, commonly known as granny flats. This means that for the 69 Local Government Areas (LGAs) falling under the Inland Code, obtaining approval for a Granny Flat requires a Development Application (DA).
Cubitt’s Granny Flats advocates for affordable housing solutions, drawing inspiration from Queensland’s grant incentives for smaller builds.
