Georges River Council · Lot Size Map

Can I subdivide in Georges River? The minimum lot sizes

The Georges River Local Environmental Plan 2021 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 Georges River'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
R2 Low Density Residential 2,516 ha zoned, about 24% of it blank on the Lot Size Map	450 m²	about 77%	900 m²	1,350 m²
	700 m²	about 23%	1,400 m²	2,100 m²
	Other mapped values (3)	under 1%	–	–
R3 Medium Density Residential 58 ha zoned, about 15% of it blank on the Lot Size Map	800 m²	nearly all	1,600 m²	2,400 m²
	Other mapped values (1)	under 1%	–	–
R4 High Density Residential 265 ha zoned, about 24% of it blank on the Lot Size Map	1,000 m²	nearly all	2,000 m²	3,000 m²
	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 10 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 Georges River's blank residential land against the NSW cadastre: none fell on a land lot, so the blank land is mostly roads and other unlotted land. 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 700 m²: 950 ÷ 700 = 1.3. 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.

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.
