In NSW the residential zones come from the Standard Instrument LEP: R2 Low Density Residential is for detached houses and, since 1 July 2024, dual occupancies almost everywhere; R3 Medium Density Residential is for townhouses, terraces and manor houses; R4 High Density Residential is for residential flat buildings; and RU5 Village is the mixed housing and small business zone for country towns. The zone name tells you the intent, but the land use table in your council’s LEP tells you what is actually permitted, and the development standards (height, floor space ratio, lot size) tell you how much. Since 28 February 2025 the Low and Mid-Rise Housing reforms have also added state-level permissibility in R2, R3 and R4 zones near nominated centres in the Six Cities Region.
Key takeaways
- Zone names and objectives are fixed by the Standard Instrument, but each council chooses most of the permitted uses in its own land use table.
- R2 permits dwelling houses everywhere and, following Stage 1 of the housing reforms, dual occupancies and semi-detached dwellings across most of NSW.
- R3 typically permits multi dwelling housing, and R4 typically permits residential flat buildings, but the height and FSR maps decide the real capacity.
- RU5 Village is the regional town zone, usually permitting houses, dual occupancies and small shops together, often with no floor space ratio at all.
- Within 800 metres of nominated town centres and stations in the Six Cities Region, the Stage 2 reforms permit terraces, townhouses and manor houses in R2 and mid-rise apartments in R3 and R4.
How a zone actually works in an LEP
The Standard Instrument (Local Environmental Plans) Order 2006 gives every council the same set of zone names, the same zone objectives and a short list of uses that must be permitted or prohibited in each zone. Everything else in the land use table is a local choice. That is why multi dwelling housing is permitted in R2 under some LEPs and prohibited under others.
Reading a zone therefore takes three steps. Find the zone on the NSW Planning Portal Spatial Viewer. Read the land use table for that zone in the LEP. Then read the height of buildings map, the floor space ratio map and the lot size map, because the zone permits a use and the maps limit its size. A site can be zoned R4 with a height limit that only allows three storeys.
R2 Low Density Residential
R2 covers most of the established suburbs of Sydney, the Central Coast, the Hunter and the Illawarra. Dwelling houses are permitted everywhere, and secondary dwellings are permitted through Chapter 3 of the State Environmental Planning Policy (Housing) 2021. Stage 1 of the Low and Mid-Rise Housing reforms made dual occupancies and semi-detached dwellings permissible in R2 across NSW from 1 July 2024, with limited exclusions, so the old question of “does this council allow duplexes in R2” now has a mostly yes answer. The minimum lot size for a dual occupancy still comes from the LEP and varies by council.
Height in R2 is commonly 8.5 or 9 metres (two storeys), and FSR is either set on the map or left to the DCP through site coverage and landscaped area controls. Blacktown LEP 2015, Penrith LEP 2010 and The Hills LEP 2019 each handle R2 FSR differently, so check the map.
Within 800 metres walking distance of a nominated town centre or station in the Six Cities Region, Stage 2 of the reforms (from 28 February 2025) also permits terraces, townhouses and manor houses in R2, with non-refusal standards for height, FSR and lot size. Outside those catchments, R2 stays a house and dual occupancy zone unless the LEP says otherwise.
R3 Medium Density Residential
R3 is the townhouse zone. Multi dwelling housing, which covers townhouses and villas, is the mandatory use, and most LEPs also permit dual occupancies, manor houses and multi dwelling housing (terraces). Some councils permit residential flat buildings in R3 and others prohibit them, and this single line in the land use table separates a three-storey walk-up site from a townhouse site.
R3 heights commonly sit between 9 and 12 metres, with FSR around 0.5:1 to 1:1 depending on the council and the location. The DCP then adds site coverage, deep soil, private open space and parking rates that often bind before the FSR does. Within the Stage 2 catchments, R3 sites gain permissibility for residential flat buildings up to a set height that steps down with distance from the centre.
R4 High Density Residential
R4 is the apartment zone. Residential flat buildings are the mandatory permitted use, and most LEPs also allow shop top housing near centres and multi dwelling housing as a fallback. Heights and FSRs in R4 vary enormously, from around 12 metres at the edge of a centre to 30 metres or more beside a railway station, and this is the zone where the maps do all the work. Two R4 sites in the same LGA can carry a threefold difference in capacity.
Apartment development in R4 also brings the Apartment Design Guide into play, and its solar access and cross ventilation tests, not the FSR, usually decide how many units fit on a narrow lot.
RU5 Village
RU5 Village is the zone for small towns in regional NSW and on the fringe of the metropolitan area. It is deliberately mixed: dwelling houses, dual occupancies and often multi dwelling housing sit alongside shops, cafes and light industry in the same land use table. Many RU5 zones carry no FSR and a modest height limit, which makes them more flexible than they look.
The constraints in RU5 are usually physical rather than planning. Reticulated sewer may be absent, flood and bushfire are common, and the council is often the water and sewer authority with its own connection rules. Dubbo Regional LEP 2022, Wagga Wagga LEP 2010 and Tamworth Regional LEP 2010 all use RU5 for their outlying villages, and the answer to “what can I build” is frequently “whatever can be serviced”.
The four zones side by side
| Zone | Typical housing permitted | Where the capacity is set | Watch for |
|---|---|---|---|
| R2 Low Density Residential | Houses, dual occupancies, secondary dwellings; terraces and manor houses near nominated centres | Height map, lot size map, DCP site coverage | Dual occupancy minimum lot size, Torrens subdivision clause |
| R3 Medium Density Residential | Townhouses, villas, terraces, manor houses, sometimes flats | Height and FSR maps, DCP deep soil and parking | Whether residential flat buildings are listed |
| R4 High Density Residential | Residential flat buildings, shop top housing | Height and FSR maps, Apartment Design Guide | Solar and ventilation tests on narrow sites |
| RU5 Village | Houses, dual occupancies, small business, often multi dwelling housing | Servicing, flood and bushfire more than the maps | No sewer, council as water authority |
Where buyers go wrong with zones
- Reading the zone and stopping. The land use table and the maps decide yield, not the colour on the plan.
- Assuming R3 means apartments. In many councils it means townhouses only.
- Forgetting the reforms have boundaries. Stage 2 applies within 800 metres walking distance of nominated centres in the Six Cities Region, and the Department publishes the maps. A site 900 metres away is assessed on the LEP alone.
- Ignoring exclusions. Heritage items and hazard-affected land are excluded from the reforms.

Frequently asked questions
What can I build on R2 zoned land in NSW?
A dwelling house, a secondary dwelling under the Housing SEPP, and since 1 July 2024 a dual occupancy or semi-detached pair in most councils, subject to the LEP minimum lot size. Near nominated centres in the Six Cities Region, terraces, townhouses and manor houses are also permitted under the Stage 2 reforms.
What is the difference between R3 and R4 zoning?
R3 Medium Density Residential is built around multi dwelling housing such as townhouses and villas, and residential flat buildings are only permitted where the council has chosen to list them. R4 High Density Residential is built around residential flat buildings, with height and FSR maps that allow apartments.
Can you build a duplex in an RU5 Village zone?
Usually yes, because most RU5 land use tables list dual occupancies, and Stage 1 of the housing reforms did not need to add them. The practical limits are sewer availability, effluent disposal on unsewered lots, and flood or bushfire mapping.
Does the zone tell me the height limit?
No. The height of buildings map in the LEP sets the limit for each parcel, and it can differ within a single zone. Read the map on the Planning Portal for the exact lot before relying on a typical figure.
URBA’s planners read the zone, the land use table and the maps together and tell you what your site can carry under the LEP and the current reforms. See our dual occupancy and duplex planning service, or request a fee proposal with the address and we will check the zoning for you.
