Cromer zoning & planning overlays

A planning-constraint profile of Cromer (Northern Beaches, NSW) - 6.32 km², mapped from live council and state overlay data. This suburb is highly constrained on the overlays we hold - no flood mapping covers this suburb, so this is not a suburb-wide verdict.

Elevation hillshade with street names, clipped to Cromer's boundary, with the bushfire and environmental overlays drawn on top. It shows where constraints fall; the interactive map shows them on your exact address. No flood layer is drawn because we hold no flood mapping for this area.

Across its 6.32 km², Cromer 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, 55% is flagged bushfire-prone. There are 5 heritage-listed sites on record, and the dominant land-use zone is Low Density Residential. The median lot measures about 625 m² across 2,556 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.

Cromer planning - frequently asked

Is Cromer flood-prone?

We don't yet hold flood mapping covering Cromer, 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. Northern Beaches 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 Cromer bushfire-prone?

Yes - around 55% of Cromer is mapped as bushfire-prone, compared with a Northern Beaches average of 47%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

What is the zoning in Cromer?

The dominant planning zone in Cromer is Low Density Residential, though the suburb also includes Deferred Matter and Special Activities. Zoning sets what you can build and do on a site, and can differ lot by lot.

Does Cromer have heritage-listed places?

Cromer has 5 heritage-listed places on record. Heritage listing affects what you can alter or demolish, so confirm whether a specific property is listed or near a heritage place.

What is the typical lot size in Cromer?

Across 2,556 surveyed parcels in Cromer, the median lot size is about 625 m². There are also 41 registered easements mapped in the suburb - an easement can restrict where you can build, so always check the title and overlays for the specific lot.

The wider Cromer statistical area, which contains Cromer, went from 7,340 people in 2001 to 8,400 in 2025, up 14%.

On the ABS SEIFA 2021 index of relative socio-economic advantage and disadvantage (IRSAD), Cromer scores 1105 and sits in decile 10 of 10 nationally and decile 10 within New South Wales - decile 1 being the most disadvantaged tenth of Australian suburbs and decile 10 the least. The national average score is 1000. SEIFA summarises income, education, occupation and housing across the whole suburb, so it describes the area, not any particular household in it.
