How many car parking spaces are required for a dual occupancy?

For a dual occupancy, the parking requirements depend on the residential zone and the number of bedrooms in each dwelling.

For RZ1 and RZ2:

• At least 1 car parking space per dwelling.
• Plus 1 additional space for every five 2-bedroom dwellings.
• Plus 1 additional space for every three dwellings with 3 or more bedrooms.

For a typical dual occupancy of only two dwellings, this means the starting requirement is 2 parking spaces in total — one for each dwelling. Additional parking is calculated across the development according to the bedroom-based rates above.

For RZ3, RZ4 and RZ5, the same resident parking rates apply. Visitor parking is additionally required where a development contains 4 or more dwellings, so this visitor-parking requirement would not normally apply to a two-dwelling dual occupancy.
