Perth Block Zones - R Zones

R Zones (or R-Codes) are used for the assessment of residential subdivision proposals in Perth. With a rapidly growing city like ours, these zones help to control growth and provide a framework for development of blocks and land.

The codes outline how many residences can go on a one-hectare (10,000 sqm) block. Each code also explains the smallest and average size of a residential block within the area. They do go deeper than outlining the number of homes and density on a block.

Other areas they cover include:

  • Type of dwelling
  • Max. plot ratio, (for apartments)
  • Min. open space rule
  • Max. dwelling height allowed
  • Required boundary setbacks
  • Streetscapes
  • Parking and access required
  • Site works

Three of the most common R Zones are:

R20
Single house or group dwellings

Min. site area per dwelling – 350sqm
Min. site area per dwelling – 450sqm
For example.
1000sqm block has the following subdivision potential:
2 dwellings.

R30
Single house or group dwellings
Min. site area per dwelling – 260sqm
Min. site area per dwelling – 300sqm
For example.
