Is my property subdivisible?

A number of factors determine whether a property is subdivisible including, but not limited to, the following:

• The zoning (e.g. ‘Residential’) and density code (e.g. ‘R20’) of your property.
• The minimum and average lot size requirement for your particular density code (see link below).
• Location of existing and proposed services (e.g. Water Corporation water pipes and sewer connections, Western Power assets, telecommunications, etc.).
• Whether the property abuts a laneway.
• Will there be sufficient area if the existing house is retained, accounting for setbacks, outdoor living areas etc. to the new boundary(s).
• Will the creation of a new lot require the removal of street trees to provide vehicular access.
• A number of other factors that may apply on a case by case basis.

Even if your property meets the applicable minimum and average lot size requirements under Table 1 of the Residential Design Codes (R-Codes) – Volume 1, it does not mean subdivision is necessarily achievable. It is recommended that adequate due diligence with all interested agencies is carried out before applying and that the services of a Licensed Surveyor (or similar) are engaged to assist you with the application process.

Who determines my subdivision application?

The Western Australian Planning Commission (WAPC), through the Department of Planning, Lands & Heritage (DPLH), is responsible for processing and determining all subdivision applications.

The Town of Mosman Park is only a referral body that provides comments and recommends conditions on a proposed subdivision.

Further information relating to subdivision can be obtained on the DPLH Website.
