The Process - Application for subdivision/amalgamations are made to the Western Australian Planning Commission (WAPC).  The WAPC sends copies of the application to a number of organisations, including the local government, for their comment.

The shire will respond within 42 days with a letter recommending either approval, refusal or deferrral.

After comments are received from the Council and other Government agencies, the application for the subdivision of land is considered by the Western Australian Planning Commission.

If the WAPC issues approval, it will usually include conditions requested by the Shire and other Government agencies.  The subdivider will undertake the necessary work and then writes to the Shire and other Government agencies to request 'Clearance' of the conditions.

Once all the conditions have been cleared, the titles to the new lots will be requested by Landgate.

Can your property be Subdivided - All properties in the Shire of Mundaring have a zone under the Town Planning Scheme, and each zone has rules including a minimum lot size. Where a property is at least twice the minimum lot size it may have potential for subdivision.

Besides the size of the lot there are other matters that require consideration; including effluent disposal, access, the environmental impact and fire risks.
