The Residential Design Codes explained – one piece at a time.

Issue 4: R-Codes Clause 5.3.3 – Parking – C3.1

This provision, one of three ‘deemed-to-comply’ provisions listed under this clause, states the following:

C3.1 – The following minimum number of on-site car parking spaces is to be provided for each single house, grouped dwelling and special purpose dwelling comprising the following number of bedrooms:

Type of dwelling Car parking spaces 
Location A Location B
1 bedroom dwelling 1 1
2 + bedroom dwelling 1 2
Aged persons’ dwelling 1 1
Ancillary dwelling nil 1

A = within:

  • 800m of a train station on a high frequency rail route, measured in a straight line from the pedestrian entry to the train station platform to any part of a lot; or
  • 250m of a high frequency bus route, measured in a straight line from along any part of the route to any part of a lot.

B = not within the distances outlined in A above.

To summarise the above, ‘Location A’ is representative of areas deemed to have sufficiently convenient access to public transport so as to provide an attractive and viable alternative to the use of private vehicles for transportation. Meanwhile, ‘Location B’ represents areas which are not serviced by public transport as frequently or conveniently as areas in ‘Location A’. As depicted in the above table, less car parking bays are required in general for dwellings deemed to be in ‘Location A’.

These car parking concessions are designed to not only encourage the use of public transportation in areas already well serviced, but to also to reward developers and allow for increased design flexibility. For instance, in regards to a common 2+ bedroom dwelling, not having to provide a second car bay allows for an additional 2.4m by 5.4m (~13m2) area which can be developed, and for the remainder of the dwelling to feature a wider façade facing the street. While this may not have much of a benefit for larger lots, it is particularly beneficial for the increasing amount of smaller, higher density lots located near train stations.

The above-mentioned R-Codes ‘deemed-to-comply’ provision reflects upon the larger focus on what is referred to as ‘Transit Oriented Development’, or ‘TOD’ for short. The idea of TOD’s is to ensure that the development density of urban areas correlates with public transport networks. Facilitating increased development closer to areas adequately serviced by public transport provides the following benefits:

  • Increases the viability of public transport routes and maximizes their efficiently
  • Reduces the demand for land on the fringes of the city by providing new dwellings within established areas.
  • Minimises the reliance on private cars for transport by providing people with a wider range of housing options located close to frequent and convenient public transport.
  • Minimises increased traffic caused by a growing population by:
    • Providing new dwellings less reliant on private cars for transportation, and
    • Limiting the demand for housing located on the edges of the city where they are heavily reliant on private vehicles for transportation.

Although many living in major urban areas such as Perth and Mandurah remain heavily reliant on private vehicles for transportation and are relatively vast in area compared to their population size, many new TOD projects, planning policies, and other initiatives are already underway, and are continuing to be devised and refined. R-Codes Clause 5.3.3 – Parking – C3.1 merely represents one provision which has TOD in mind.
