Proposed changes to the assessment of multiple dwellings at R30/R35, parking and other incidental changes.

R-CodesTBB have been following, with interest, the proposed changes to State Planning Policy 3.1 – Residential Design Codes for some time now.

The amendment proposes to require each multiple dwelling at R30 and R35 to achieve the same site area and open space requirement as currently applies for single and grouped dwellings, as well as increased parking requirements and other incidental changes.

The WAPC has now proceeded to public advertising of this proposal following an initial consultation period with local government and key stakeholders. Whilst TBB understands the response to the amendment has been mixed within the industry, many local governments have been in favour of the changes following community concern regarding the perceived adverse impacts of multiple dwelling developments in established suburbs.

The 60 day advertising period closes at 5pm on Friday 14 November 2014.

What are the changes?

The amendment proposes to remove the plot ratio provisions for determining maximum yield for R30 and R35 sites (currently at a plot ratio of 0.5 and 0.6 respectively) and replace these with average site area per dwelling provisions equal to those of single house or grouped dwellings (i.e 300m2 at R30 and 260m2 at R35). These changes essentially mean that a 1000m2 site at R35 which could currently potentially yield around eight dwellings would be reduced to a maximum of three dwellings.

Additionally, the amendment proposes to increase the minimum parking standards for some multiple dwellings by removing the concessions for small dwellings (<75m2 or 1 bedroom), as well as amending several R-Codes clauses, definitions, figures and tables to rectify drafting errors and anomalies.

The existing provisions are what have made low rise apartment developments attractive on R30/R35 sites post-2010, when the provisions were first introduced. Whilst this development type has typically been targeted by private developer/investors on infill sites where larger R30/R35 lots still exist, the proposed changes also have implications for the development potential of greenfield sites at these densities.
