Zones in Hornsby
Low Density Residential covers the most land by parcel count — 36,178 parcels, about 84% of the council. These are the 8 most common zones across all 43,106 parcels.
| Zone | Parcels | Share |
|---|---|---|
| Low Density Residential | 36,178 | 83.9% |
| Primary Production Small Lots | 1,080 | 2.5% |

| Local Centre | 351 | 0.8% |
1,578 parcels carry more than one zone. On a split lot the controls differ across the block, so a single zone label for the property can be misleading — the map shows each part and its area.
Constraints mapped in Hornsby
Overlays decide what you can actually build, and they are mapped per property rather than per council. These totals show how much of Hornsby carries each one — and, just as importantly, how much of it nobody has assessed.
Bushfire
43.1%
18,578 parcels (43.1%) are inside a mapped bushfire overlay. The rest sit outside it, so the bushfire planning controls do not apply there — not that the land cannot burn.
Flood
16.61%
7,162 parcels (16.61%) are inside mapped flood areas. 83.39% of Hornsby has no flood mapping at all — those parcels are unassessed, not cleared.
Heritage
10.84%
4,671 parcels (10.84%) are inside a mapped heritage overlay. The rest sit outside it, so the heritage planning controls do not apply there — not that a property here could never be listed in future.
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.

How many properties are in Hornsby?
Our map holds 43,106 parcels for Hornsby, covering about 230 km². That is what our map holds for this council. It is drawn from the state cadastre, but some parcel types are deliberately left out — strata unit lots stacked on their base parcel, and easements — so it is not the same as a count of titles.
Is this zoning information official?
It is built from the New South Wales government's own published spatial data, but it is a snapshot taken on 2026-09-06 and is not a substitute for a planning certificate. For a decision that matters, check the address live and confirm with Hornsby council.
