Mullumbimby zoning & planning overlays

A planning-constraint profile of Mullumbimby (Byron, NSW) - 27.59 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 Mullumbimby'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 27.59 km², Mullumbimby 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, 92% is flagged bushfire-prone. There are 47 heritage-listed sites on record, and the dominant land-use zone is Primary Production. The median lot measures about 728 m² across 2,071 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.

Mullumbimby planning - frequently asked

Is Mullumbimby flood-prone?

We don't yet hold flood mapping covering Mullumbimby, 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. Byron 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 Mullumbimby bushfire-prone?

Yes - around 92% of Mullumbimby is mapped as bushfire-prone, compared with a Byron average of 94%. A bushfire-prone designation can trigger additional building requirements, so check the specific address.

What is the zoning in Mullumbimby?

The dominant planning zone in Mullumbimby is Primary Production, though the suburb also includes Rural Landscape and Environmental Conservation. Zoning sets what you can build and do on a site, and can differ lot by lot.

Does Mullumbimby have heritage-listed places?

What is the typical lot size in Mullumbimby?
