How Double Bay is zoned
Buying in Double Bay? The zoning, flood and bushfire lines on the section 10.7 certificate attached to the contract are mapped controls - see our s10.7 certificate guide.
Across its 0.78 km², Double Bay is relatively unconstrained by the planning overlays we hold. We hold no flood mapping covering this suburb, so no flood figure is shown - that is a gap in our data, not an all-clear. There are 59 heritage-listed sites on record, and the dominant land-use zone is Medium Density Residential. The median lot measures about 369 m² across 950 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.

Bushfire mapping covers Double Bay and little to none of it is mapped as bushfire-prone. Always confirm for the exact lot, as mapping can change.
