How Croydon South is zoned
Selling in Croydon South? The zoning and planning overlays on this page are the controls a Section 32 vendor statement discloses - a $9 planning report pulls them at the lot level for any Croydon South address.
Across its 2.56 km², Croydon South is highly constrained by planning overlays. Flood mapping covers the suburb and none of it falls within a mapped flood overlay. There are 4 heritage-listed sites on record, and the dominant land-use zone is Neighbourhood Residential Zone (NRZ3). The median lot measures about 612 m² across 2,576 parcels. These figures are suburb-wide - the overlays that actually apply to a given lot can differ block to block, which is what a property-level check tells you.
