How St Kilda is zoned
Selling in St Kilda? 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 St Kilda address.
Across its 3.16 km², St Kilda is moderately constrained by planning overlays. About 14% of the suburb sits within a mapped flood overlay. There are 220 heritage-listed sites on record, and the dominant land-use zone is General Residential Zone (GRZ1). The median lot measures about 997 m² across 18,851 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.

Where can I see a flood map of St Kilda?

What is the zoning in St Kilda?
The dominant planning zone in St Kilda is General Residential Zone (GRZ1), though the suburb also includes Public Park and Recreation Zone (PPRZ) and Transport Zone (TRZ2). Zoning sets what you can build and do on a site, and can differ lot by lot.
Does St Kilda have heritage-listed places?

What is the typical lot size in St Kilda?
