How Charmhaven is zoned
Buying in Charmhaven? 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 6.96 km², Charmhaven is highly constrained 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. Of what is mapped, 81% is flagged bushfire-prone. The dominant land-use zone is Transition. The median lot measures about 654 m² across 1,307 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 Charmhaven flood-prone?
We don't yet hold flood mapping covering Charmhaven, 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. Central Coast 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 Charmhaven bushfire-prone?
Yes - around 81% of Charmhaven is mapped as bushfire-prone, compared with a Central Coast average of 69%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.
What is the zoning in Charmhaven?
The dominant planning zone in Charmhaven is Transition, though the suburb also includes Environmental Conservation and Low Density Residential. Zoning sets what you can build and do on a site, and can differ lot by lot.

What is the typical lot size in Charmhaven?
