How North Sydney is zoned
Buying in North Sydney? 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 1.47 km², North Sydney 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 321 heritage-listed sites on record, and the dominant land-use zone is Infrastructure. The median lot measures about 312 m² across 1,222 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.

Is North Sydney flood-prone?
We don't yet hold flood mapping covering North Sydney, so this page can't say how much of the suburb is flood-affected - that is a gap in our data, not an indication that the suburb is free of flood risk. North Sydney is the authority to check for flood mapping in this area. Flood overlays vary block to block, so whether a particular lot is affected needs a property-level check.
Is North Sydney bushfire-prone?
Bushfire mapping covers North Sydney and little to none of it is mapped as bushfire-prone (the North Sydney average is 4%). Always confirm for the exact lot, as mapping can change.
What is the zoning in North Sydney?
The dominant planning zone in North Sydney is Infrastructure, though the suburb also includes Low Density Residential and Public Recreation. Zoning sets what you can build and do on a site, and can differ lot by lot.
Does North Sydney have heritage-listed places?
