What can I build in R1 General Residential?
R1 General Residential is the zone NSW councils use where they want a mix of housing types side by side: houses, semi-detached homes, townhouses and apartment buildings. Of the five residential zones, it is the one where the state requires councils to allow the widest range of housing.
This page covers what the state guarantees in R1, what your council decides for itself, and the questions people ask most before they buy or build. Type your address below to check whether your block is R1, along with its height, floor space ratio and lot size maps.

What can I build in R1 General Residential?
Almost any kind of housing, with development consent. The Standard Instrument, the template every council's Local Environmental Plan (LEP) is built on, requires every R1 zone to permit dwelling houses, semi-detached dwellings, attached dwellings, multi dwelling housing (townhouses), residential flat buildings (apartments), shop top housing, boarding houses, hostels, group homes and seniors housing. It also requires child care centres, community facilities, neighbourhood shops, places of public worship and respite day care centres. Home occupations are allowed without consent.
The zone's objectives are to provide for the housing needs of the community, to provide a variety of housing types and densities, and to allow other uses that meet residents' day to day needs. The council must have regard to those objectives when it decides a development application, so a proposal that fits them has an easier path.
Councils can add more uses to that list, and many do. 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 R1?
Usually yes, but a dual occupancy is not on the state's compulsory list for R1, so check your council's land use table. Most R1 zones include it, and semi-detached dwellings (two homes joined by one wall, each on its own lot) are compulsory in every R1 zone, which covers many duplexes once they are subdivided.
Where a dual occupancy is permitted and the block is in a low and mid rise housing area (within 800 metres walk of a listed station or town centre), the Housing SEPP sets standards the council cannot ask more than: 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 development control plan (DCP) set the numbers.
Can I build townhouses or apartments in R1?
Yes, with development consent, because multi dwelling housing and residential flat buildings are on the compulsory list for every R1 zone. Manor houses (small two storey buildings of three or four homes) are also permitted, because the Codes SEPP allows them in any R1 zone where townhouses or apartments are.
In a low and mid rise housing area, the Housing SEPP caps what the council can demand. For townhouses the lot need be no more than 600 m² with a 12 metre frontage, and for terraces 500 m² with an 18 metre frontage, both at a floor space ratio of 0.7:1 and a height of 9.5 metres. For an apartment building in R1 it is 500 m² and 12 metres, at 0.8:1 and 9.5 metres. Elsewhere your LEP's height and floor space ratio maps and the DCP decide the size.
Can I build a granny flat in R1?
Yes. The Housing SEPP permits a secondary dwelling with consent on R1 land wherever a house is permitted, and a house is permitted in every R1 zone. It can be up to 60 m² of floor area, or more if your LEP allows a larger one, and it can't be subdivided off and sold separately.
It can often be approved as complying development by a certifier instead, 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.
Can I subdivide an R1 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 are set council by council on the Lot Size Map, and some councils set separate minimums for particular housing types. Minimum lot size explains how to read yours.
The 2025 reforms added exceptions in low and mid rise housing areas. A new dual occupancy approved on or after 28 February 2025 can be Torrens title subdivided into two lots of at least 225 m² and 6 metres wide, and a new terrace row into lots of at least 165 m², whatever the LEP minimum, as long as each lot has one home and frontage to a public road. Neither rule covers strata subdivision.
What is the height limit in R1?
It is whatever your council's Height of Buildings Map shows for the block, and it varies more in R1 than in any other residential zone because the zone holds everything from houses to apartments. The Standard Instrument makes the height clause optional, so some councils map no height and control it through the DCP instead. No mapped height does not mean no limit.
A house approved as complying development under the Housing Code can be up to 8.5 metres above existing ground level. Building height explains how height is measured and why a sloping block changes the answer.
Can I run a business from home in R1?
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 R1 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.
Can I use complying development in R1?
Often, yes. The Housing Code covers a new one or two storey house, and alterations and additions, on an R1 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 R1 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?
Could an apartment building go up next door to me in R1?
Yes, it is possible, because residential flat buildings are permitted with consent in every R1 zone. How tall and how big it could be depends on the height and floor space ratio maps for that lot, the DCP, and whether the lot is in a low and mid rise housing area. Neighbours are usually notified of a development application and can make a submission.
Is R1 better than R2 for building a second home on the block?
R1 guarantees more housing types than R2: townhouses and apartments are compulsory in R1 and only permitted in R2 in low and mid rise housing areas. For a single granny flat or a duplex the difference is smaller, since both zones usually allow them. The lot size, frontage and constraints on your block matter as much as the zone.
Does R1 zoning mean I can build anything residential?
No. The zone makes the use permissible, which means you can apply. Your design still has to meet the LEP's height, floor space ratio and lot size controls, the DCP, and any constraints on the land such as heritage, flood or bushfire, and council can refuse a proposal that doesn't.
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.
