The R-Codes provide the basis for the control of residential development and subdivision throughout Western Australia.

Following an extensive period of stakeholder engagement, the Department of Planning has instigated a set of amendments to the R-Codes (2013). The amendments aim to address emerging design trends, promote sustainability, improve clarity and highlight assessment pathways to facilitate better residential design outcomes throughout Western Australia. Recent publicity on this amendment has been flagged as commitment to increased urban density through (in part) the better utilisation of granny flats and multi-family developments.

The Department of Planning has released guidance documents and is undertaking an education programme to ensure stakeholder familiarisation and preparation ahead of their implementation. The R-Codes (2013) will take effect upon publication in a special edition of the Government Gazette on Friday 2 August 2013.
