Can I subdivide in Central Coast? The minimum lot sizes
The Central Coast Local Environmental Plan 2022 sets a minimum lot size for each area on its Lot Size Map. By area alone, a block must be at least twice that size to split into two lots. This page shows the minimums mapped in Central Coast's residential zones and how much of each zone they cover. It is indicative, not advice.
Indicative only, not a planning certificate. These figures come from public planning maps. They are not a planning certificate (section 10.7 certificate), a survey or advice, and they do not say whether the council would approve a subdivision.
Minimum lot sizes mapped in residential zones
| Zone | Mapped minimum | Share of the zone's mapped part | Block area for 2 lots, by area alone | For 3 lots, by area alone |
|---|---|---|---|---|
| R1 General Residential 2,202 ha zoned, about 66% of it blank on the Lot Size Map | 450 m² | about 5% | 900 m² | 1,350 m² |
| 550 m² | about 94% | 1,100 m² | 1,650 m² | |
| Other mapped values (2) | about 1% | – | – | |
| R2 Low Density Residential 8,791 ha zoned | 450 m² | about 46% | 900 m² | 1,350 m² |
| 550 m² | about 51% | 1,100 m² | 1,650 m² | |
| 1,850 m² | about 3% | 3,700 m² | 5,550 m² | |
| Other mapped values (4) | under 1% | – | – | |
| R3 Medium Density Residential 194 ha zoned, about 97% of it blank on the Lot Size Map | The Lot Size Map sets a minimum on only about 3% of this zone (300 m²). Most of it has no mapped minimum, so SplitCheck cannot assess a split there by area. | |||
| R5 Large Lot Residential 500 ha zoned | 1,800 m² | about 10% | 3,600 m² | 5,400 m² |
| 20,000 m² (2 ha) | about 90% | 40,000 m² (4 ha) | 60,000 m² (6 ha) | |
| Other mapped values (1) | under 1% | – | – | |
Shares are of the part of each zone that the Lot Size Map covers. They are estimates from sampling the Land Zoning and Lot Size maps on a grid about 21 m apart, so treat them as approximate. Where the map sets different minimums inside one zone, the exact lot decides which number applies.
A zone can include land the Lot Size Map leaves blank. A lot there has no mapped minimum, and SplitCheck will say it cannot assess a split by area. We checked 8 evenly spread points in Central Coast's blank residential land against the NSW cadastre: 6 fell on a land lot and 2 did not. So some real lots here have no mapped minimum. Where parts of the council area are planned under a State policy instead of the local plan, those parts are not in these figures.
Worked example. Two 950 m² blocks, both zoned R2.
Where the map says 450 m²: 950 ÷ 450 = 2.1. By area, two lots.
Where the map says 550 m²: 950 ÷ 550 = 1.7. By area, one lot. It cannot be split on area.
Same zone, same size, different answer. Area is only the first test.
What this page does not check
- Frontage and lot width. The council's development control plan (DCP) sets these, not the Lot Size Map.
- Heritage items and heritage conservation areas.
- Flooding, bush fire and other hazards on the lot.
- Easements, sewer, water and stormwater.
- Access to a rear lot, for example a battle-axe handle.
- Existing buildings, setbacks and trees.
- Units and townhouses on a strata plan. This page does not apply to them.
- Whether the council would approve it. Only a development application or a complying development certificate decides that.
Adding dwellings instead of lots
Dual occupancy, a granny flat, manor houses, terraces, multi-dwelling housing and the NSW low and mid-rise housing rules each have their own tests. Most of them add dwellings on one lot. They do not always create a new lot, so the lot counts above are not dwelling counts.
Check one address
SplitCheck reads the zone, the lot area and the mapped minimum for that exact lot, checks the NSW pathways and shows the working. A confident no counts as an answer. Three checks a month are free.
