RU4 Primary Production Small Lots zoning in NSW

Rural zones in the NSW Standard Instrument LEP. Checked 26 September 2026.

RU4 Primary Production Small Lots is for horticulture, market gardens, nurseries and other primary industry that works on smaller holdings. Its objectives are sustainable primary industry and compatible uses, diversity and employment in primary industry enterprises, particularly those that require smaller lots or are more intensive in nature, and minimising land use conflict. The Standard Instrument mandates extensive agriculture, farm buildings, intensive plant agriculture, roads and roadside stalls, home occupations without consent, and aquaculture, dwelling houses and plant nurseries with consent.

RU4 is often confused with R5 because both have smaller rural lots. The difference is purpose: R5 is for living on a large lot, RU4 is for producing on a small one. Councils zone land RU4 around Sydney's fringe and regional centres where market gardens and orchards persist.

What the Standard Instrument says

The objectives and uses every council LEP must carry for this zone, quoted from the Land Use Table. Blank items are left to the LEP.

Standard Instrument Land Use Table

Zone RU4 Primary Production Small Lots

Smaller rural holdings for intensive or specialised primary industry, such as horticulture, market gardens and nurseries, with dwellings tied to that use.

1 Objectives of zone

To enable sustainable primary industry and other compatible land uses.
To encourage and promote diversity and employment opportunities in relation to primary industry enterprises, particularly those that require smaller lots or that are more intensive in nature.
To minimise conflict between land uses within this zone and land uses within adjoining zones.

Direction: the LEP must permit, with or without consent

Extensive agriculture
Farm buildings
Intensive plant agriculture
Roads
Roadside stalls

2 Permitted without consent

Home occupations

3 Permitted only with consent

Aquaculture
Dwelling houses
Plant nurseries

4 Prohibited

Left to the council's LEP.

A council LEP adopts this entry and adds its own objectives, permitted uses and prohibited uses under the Land Use Table directions, so the LEP land use table for the land is the one that applies. Schedule 1 of the LEP, the Housing SEPP and the Codes SEPP can permit development the table does not.

What it means in practice

Where the common questions land, and which instrument decides each of them.

Dwelling houses

Permitted with consent in every RU4 LEP, usually with a minimum lot size that is smaller than RU1 but still measured in hectares, and often with a dwelling entitlement clause. The Rural Housing Code applies to RU4 lots, so a new dwelling can be complying development on lots of at least 4,000 m² where it is permissible.

Intensive plant agriculture and nurseries

Intensive plant agriculture must be permitted and plant nurseries are mandated with consent, which is what marks RU4 out. Intensive livestock agriculture is not mandated here, unlike RU1, and Chapter 2 of State Environmental Planning Policy (Primary Production) 2021 governs both where they occur.

Roadside stalls and farm gate sales

Roadside stalls are mandated in RU4, and cellar door premises, farm gate premises and artisan food and drink industries are optional uses a council can add.

Subdivision

Consent and the Lot Size Map minimum apply. RU4 minimums are generally smaller than RU1 but councils guard against the zone becoming de facto rural-residential, which is what R5 is for.

Frequently asked questions

What is RU4 zoning in NSW?

RU4 Primary Production Small Lots is the Standard Instrument zone for intensive or specialised primary industry on smaller rural lots. It mandates extensive agriculture, intensive plant agriculture, farm buildings and roadside stalls, plus dwelling houses, aquaculture and plant nurseries with consent.

Can I build a house on RU4 land?

Dwelling houses are permitted with consent in every RU4 LEP, subject to the minimum lot size and any dwelling entitlement clause. The Rural Housing Code in the Codes SEPP applies in RU4 and can make a new dwelling complying development on a lot of at least 4,000 m².

What is the difference between RU4 and R5?

RU4 is a rural production zone whose objectives are about primary industry on smaller lots; R5 is a residential zone whose objectives are about housing in a rural setting. Both permit a dwelling house with consent, but RU4 mandates agriculture and nurseries while R5 mandates neither.

Can I subdivide RU4 land?

With consent and to the minimum on the Lot Size Map. Because the zone exists to keep small productive holdings, councils rarely allow lots small enough for purely residential use.
