What can I build in R2 Low Density Residential?
R2 Low Density Residential is the most common zone for houses in NSW, and the one that changed most in the 2024 and 2025 housing reforms. A block that allowed a house and a granny flat a few years ago may now allow a duplex, and near some stations and town centres, terraces or a two storey apartment building.
This page covers what you can build in R2 today, which parts the state sets and which your council sets, and how to check your own block. Type your address below to see whether it is R2, and whether it is bush fire prone, flood affected or heritage listed, which can take the new rules away.

What can I build in R2 Low Density Residential?
A house, with development consent, on every R2 block, and on most R2 land also a granny flat and a dual occupancy (duplex). The Standard Instrument requires every R2 zone to permit dwelling houses, group homes, child care centres and respite day care centres with consent, and home occupations without consent. State policy adds more on top: the Housing SEPP permits granny flats in R2, and since 1 July 2024 dual occupancies and semi-detached dwellings.
The zone's objectives are to provide housing within a low density residential environment and to allow other uses that meet residents' day to day needs. Beyond the compulsory list, each council decides whether to allow uses such as home businesses, health consulting rooms, seniors housing or places of worship, so the full list differs from one council to the next. To see your council's full list, open its Local Environmental Plan on NSW legislation, go to Part 2 and find the zone in the Land Use Table. The Planning Portal Spatial Viewer shows the zone and the other maps for a single lot.
Can I build a duplex or dual occupancy in R2?
Yes, on most R2 land in NSW, with development consent. Since 1 July 2024 the Housing SEPP has permitted dual occupancies (two homes on one lot, attached or detached) and semi-detached dwellings in Zone R2 across the state, whatever the council's own plan says. A granny flat does not count as a dual occupancy.
The state rule doesn't reach land that the Housing SEPP's low and mid rise chapter excludes. That includes bush fire prone land, heritage items, some flood prone land in listed council areas, and all of Bathurst, Blue Mountains, Hawkesbury and Wollondilly. On excluded land a duplex is only possible if your council's LEP allows it, so check whether your block is bush fire prone before anything else.
In a low and mid rise housing area (within 800 metres walk of a listed station or town centre), a duplex that meets these numbers can't be refused for failing to meet stricter ones: a 450 m² lot, a 12 metre frontage at the building line, a floor space ratio of 0.65:1 and a height of 9.5 metres. Outside those areas your council's LEP and DCP set the lot size, frontage and design rules, and some LEPs set a separate minimum lot size for dual occupancies.
Can I build a granny flat in R2?
Yes. The Housing SEPP permits a secondary dwelling with consent on R2 land wherever a house is permitted, which in R2 is everywhere. It can be up to 60 m² of floor area, or more if your LEP allows a larger one, and the lot can hold only the main house and the granny flat. It can't be subdivided off and sold separately.
It can often be approved as complying development by a certifier, if the lot is at least 450 m² with at least 12 metres of frontage at the building line (15 metres for lots over 900 m², 18 metres over 1,500 m²) and it meets the rest of the Housing SEPP's granny flat standards. Through a development application instead, the council can't require a site larger than 450 m² for a detached granny flat, or more parking than the site already had.
Can I subdivide an R2 block?
Only if each new lot meets the minimum lot size your LEP maps for the block, unless a state rule overrides it. Minimum lot sizes come from the council's Lot Size Map and vary widely between councils, and even between suburbs. Minimum lot size explains how to read yours.
The 2025 reforms added one exception. In a low and mid rise housing area, a new dual occupancy approved on or after 28 February 2025 can be Torrens title subdivided into two lots whatever the LEP minimum, as long as each lot has one home, is at least 225 m² and 6 metres wide at the building line, has frontage to a public road and is not a battle axe lot. That rule does not cover strata subdivision.
What is the height limit in R2?
It is whatever your council's Height of Buildings Map shows for the block, and some councils map no height at all. The Standard Instrument makes the height clause optional, so there is no single R2 height across NSW. Where none is mapped, the DCP often controls height instead, so no mapped number does not mean no limit.
Two state numbers are worth knowing. A house approved as complying development under the Housing Code can be up to 8.5 metres above existing ground level. A duplex, terrace or small apartment building in a low and mid rise housing area can't be refused for height if it is 9.5 metres or lower. Height is measured from existing ground level, so a sloping block changes what fits: try the slope calculator, and read building height.
Can I run a business from home in R2?
Usually yes, within limits. Home occupations, run only by the people who live there with no goods displayed or sold by retail, are permitted without consent in every R2 zone. The state's exempt development code also lets a home business, home industry or home occupation go ahead with no approval if it doesn't make food or involve skin penetration, doesn't change the building's use, and stays within the floor area your LEP sets for a home business (at least 30 m² in every council). A home business may employ up to two people who don't live there. Anything bigger needs a development application, or may be prohibited.
How did the 2024 and 2025 low and mid rise housing reforms change R2?
They changed R2 more than any other zone. Stage 1, from 1 July 2024, permitted dual occupancies and semi-detached dwellings in R2 across NSW. Stage 2, from 28 February 2025, went further in low and mid rise housing areas: residential land within 800 metres walk of a listed station or a mapped town centre in Greater Sydney, the Central Coast, the Lower Hunter and Newcastle, and the Illawarra and Shoalhaven.
In those areas R2 now also permits multi dwelling housing (townhouses), terraces and residential flat buildings, with standards the council can't ask more than. Townhouses need no more than a 600 m² lot and a 12 metre frontage, terraces 500 m² and 18 metres, and an apartment building 500 m² and 12 metres, each at a height of 9.5 metres, which is about two storeys.
The department's indicative map shows roughly where these areas are, but the legislation decides, and excluded land such as bush fire prone land and heritage items is left out. The NSW Housing Pattern Book offers ready designs for several of these housing types: see our Pattern Book pages.
Can I use complying development in R2?
Often, yes. The Housing Code covers a new one or two storey house, and alterations and additions, on an R2 lot of at least 200 m² with at least 6 metres of frontage at the building line. The Low Rise Housing Diversity Code covers one or two storey dual occupancies, manor houses and terraces in R2 where they are permitted. A certifier approves complying development without a development application, but only if the design meets every standard in the code and the land isn't ruled out by heritage, some flood and bushfire categories or other constraints. See complying development.
What else do people ask?
Is a granny flat the same as a dual occupancy?
No. A granny flat (secondary dwelling) is capped at 60 m² unless the LEP allows more, must stay on the same lot as the main house and can't be sold separately. A dual occupancy is two full dwellings of any size the controls allow, and in a low and mid rise housing area it can be subdivided into two lots.
Can council refuse a duplex in R2?
Council can refuse a duplex that fails its planning controls or doesn't fit the zone objectives, but on most R2 land it can no longer refuse one simply because duplexes are not allowed. On land the state rule excludes, such as bush fire prone land or a heritage item, the council's own LEP still decides whether a duplex is permitted at all.
Does R2 mean single storey only?
No. R2 means low density, not one storey. Two storey houses are common in R2, and the height you can build to comes from the height map, the DCP or, for complying development, the Housing Code's 8.5 metres.
Can I build a house and a granny flat at the same time?
Yes. The Housing SEPP lets a new house and a granny flat be approved together as one complying development certificate, if both meet their codes. They can also go in one development application.
Where does this information come from?
Permitted uses differ by council LEP, so check your council's land use table before you rely on anything here. This page is general information about NSW planning law, not advice about your block. It is not a section 10.7 planning certificate, and it does not replace your council, your certifier, legal advice or your own designer.
