How to check land zoning in NSW and what the zone means for a buyer

Where zoning comes from

Zoning in NSW is set by each council's local environmental plan, its LEP. Hornsby Shire Council describes its LEP as Council's main planning instrument, outlining what can be developed where, made of both a written instrument and maps. Every principal LEP in the state is built on one template, the Standard Instrument (Local Environmental Plans) Order 2006, gazetted on 31 March 2006, which prescribes the standard form and content of a principal LEP under section 3.20 of the Environmental Planning and Assessment Act 1979.

The department's circular on the Standard Instrument sets out what a council can and cannot do with it. A council can add local objectives to a zone, add permitted or prohibited land uses to the zone's land use table, decide whether to adopt the optional clauses, and prepare the maps that specify lot sizes, building heights and floor space ratios for its area. A council cannot add new zones, prohibit a use the Standard Instrument mandates as permissible, permit one it mandates as prohibited, or change the standard definitions or clause numbering. So an R2 zone in Hornsby and an R2 zone in Parramatta share the same core objectives and the same mandated uses; they differ in the uses the council added and in the numbers on its maps.

The circular also describes overlays: local provisions made of a map and heads of consideration that apply in addition to the zoning of the land, for environmental, hazard or design constraints, and which may cross several zones. An overlay cannot alter the mandated permissible or prohibited uses, but it can add tests a DA must pass. The LEP maps themselves are made available on the NSW Planning Portal.

The zones

The department's practice note on standard zones, issued 10 March 2011, says the Standard Instrument sets out 35 standard zones and that councils may select from them but may not add new zones, create subzones or change a zone's name. Only the zones a council uses appear in its LEP. Two reforms since then renamed part of the list, and both matter when you read an older document.

The employment zones reform was made by six self-repealing state policies on 16 December 2022, amending 134 LEPs, with effect on 26 April 2023. The department's equivalent zone tables, dated April 2023, show the translation council by council: for Hornsby, B1 and B2 became E1 Local Centre, B3 became E2 Commercial Centre, B4 became MU1 Mixed Use, B5 and B6 became E3 Productivity Support, IN1 and IN2 became E4 General Industrial and IN4 became W4 Working Waterfront; Newcastle's IN3 Heavy Industrial became E5 Heavy Industrial. Some areas were translated to a non-direct equivalent, which the tables mark. In the same reform the environment zones were renamed conservation zones, C1 to C4, a change of name for administrative reasons because, in the department's words, the term environment zone was too broad and confusing. The practical consequence: an "E2" in a 2020 planning certificate was Environmental Conservation; an "E2" in a 2024 one is Commercial Centre. Check the date on anything that names a zone.

Look up the address

The free tool is the NSW Planning Portal Spatial Viewer, at planningportal.nsw.gov.au/spatialviewer, which the department describes as information-rich maps for every address and lot in NSW and links from its home page with the words "search your address to see zoning, planning controls and development opportunities for your land". The portal's own guide to it, Using the Spatial Viewer, gives the steps.

1. Open the viewer, or click the Find a Property button on the Planning Portal home page. You may be asked to accept terms and conditions.
2. In the left panel, search by Address (the default), or by Lot, LGA or point of interest, and pick the match from the list. The property is outlined in yellow on the map.
3. Open Search Results in the right panel. For a residential lot it lists Land Zoning, Height of Building, Floor Space Ratio, Minimum Lot Size, Local Provisions, Local Environmental Plan and Local Aboriginal Land Council; other lots add lines such as Acid Sulfate Soils. Click the arrow on a line to see the value, for example Height of Building 8.5 m, and the outward-link icon to open the clause in the legislation.
4. Below Search Results are the SEPP Results, Development Control Plans and Contribution Plans for the site. The state policies here can override the LEP, which the section on what zoning does not tell you covers.
5. In the left panel's Layers tab, tick Land Zoning under Principal Planning Layers to colour every lot on the screen by zone. This is how you see what the block behind and the main road are zoned, and where the R2 line stops.
6. Click the Generate Property Report icon next to the address to download a PDF with a summary of planning controls, detailed planning information and other matters affecting the property. Allow pop-ups.

The zoning layer behind the viewer is published as open data, the Environmental Planning Instrument, Local Environmental Plan, Land Zoning dataset, under a Creative Commons Attribution licence. Councils publish the same maps their own way: the Planning Portal's page for the Hornsby Local Environmental Plan 2013 lists the PDF map sheets by type, 27 Land Zoning sheets, 25 Height of Buildings sheets, and Floor Space Ratio, Lot Size, Flood Planning, Additional Permitted Uses and Land Reservation Acquisition maps, with the LEP text on the legislation site last updated 7 August 2026; Hornsby Shire Council also runs an interactive map of the same controls.

Reading the land use table, and the numbers that ride with the zone

Each zone in an LEP has a land use table which, in the department's words, tells landowners, councils and other interested parties what they can and cannot do on a parcel of land. It has three lists, which the Standard Instrument numbers Item 2, Item 3 and Item 4: permitted without consent, permitted with consent, and prohibited. Anything in Item 3 needs a development application. The department's page on land use tables adds a warning: the tables list activities that are either permitted or prohibited, but there can also be other permissible uses that are not listed.

That is because most zones are written "open". The circular explains the preferred approach: list the uses allowed without consent, list the uses that will always be inappropriate as prohibited, and allow all other unnamed uses as permissible with consent, usually with the words "Any development not specified in Item 2 or 4". Environmental protection and recreation zones are the exception, written "closed": only the listed uses are permitted and everything else is prohibited. So in an open residential zone, a use you cannot find in the table is probably allowed with consent, not banned; read the last line of Item 3 before concluding either way.

Three development standards sit beside the zone, each as an optional Standard Instrument clause the council fills in and maps: height of buildings, floor space ratio and minimum subdivision lot size. The circular notes a council that wants to control these must do it through the optional clause, not a local one. They are the numbers the Spatial Viewer shows as Height of Building, Floor Space Ratio (n:1) and Minimum Lot Size. Height is in metres to the top of the building; floor space ratio is the ratio of gross floor area to site area, so 0.5:1 on a 600 square metre lot allows 300 square metres of floor; minimum lot size is the smallest lot a subdivision may create. A DA that exceeds any of them is asking for a variation, which is a matter of record on the application.

State policies can change these numbers without the council touching its LEP. The Low and Mid-Rise Housing Policy, part of the State Environmental Planning Policy (Housing) 2021, is the one a residential buyer meets. Stage 1 started on 1 July 2024 and permitted dual occupancies and semi-detached homes in the R2 zone across all of NSW. Stage 2 started on 28 February 2025 and applies to residential zoned land within 800 metres walking distance of a nominated town centre or the entrance of a nominated train, metro or light rail station. Inside those areas, multi-dwelling housing, that is terraces, is permitted with consent in R2 at a minimum lot size of 500 square metres, 18 metres width, floor space ratio 0.7:1 and height 9.5 metres; dual occupancies at 450 square metres, 12 metres, 0.65:1 and 9.5 metres; and in R3 and R4, residential flat buildings up to 2.2:1 and 22 metres, 6 storeys, within 400 metres, and 1.5:1 and 17.5 metres, 4 storeys, from 400 to 800 metres, with the LEP's minimum lot size and width provisions switched off. Whether an address is inside such an area is a question for the SEPP Results panel in the viewer, not the zone code.

What zoning does not tell you

• What will actually be approved. Permitted with consent means a DA can be lodged, not that it will succeed. The council assesses it against the zone objectives, the development standards, its development control plan and the submissions. A refused application, or an approved one with a variation, is visible only in the DA record, which the companion guide shows how to search.
• Heritage. Whether the land is a heritage item or in a heritage conservation area is a separate LEP schedule and map, not part of the zone, and it appears as its own line on the section 10.7(2) certificate.
• Overlays and hazard notations. Bush fire prone land, flood related development controls, acid sulfate soils and the other notations the 10.7(2) certificate must list ride on their own maps and apply across zones. The viewer shows some of them as extra Search Results lines; the certificate lists them all.
• State policies. The SEPPs listed in the viewer's SEPP Results panel, including the Housing SEPP and the Codes SEPP for complying development, can permit or size development the LEP alone would not. Hornsby's LEP page says the list of SEPPs applying to a specific property can be obtained from the council through a section 10.7 planning certificate.
• The vendor's claims. "Zoned for development" or "DA potential" in a listing describes the zone, not an approval. Read the land use table and the standards yourself; then read the trackers.

The authoritative statement is the section 10.7(2) planning certificate. City of Parramatta describes it as showing the zoning of the property, its relevant state, regional and local planning controls and other property issues. It is issued by the council for one parcel on one date, the vendor attaches it to the contract, and your conveyancer reads it. The viewer is how you check before there is a contract; the certificate is what you rely on once there is.

R2 next to R3 or R4, and the steps in order

The zone of the lot you are buying tells you what may happen on it. The zones of the lots around it tell you what may happen to it. The practice note describes R2 Low Density Residential as the lowest density urban residential zone and the most restrictive in the other uses it allows, typically detached houses; R3 Medium Density Residential as land where a variety of medium density accommodation is to be established or maintained; and R4 High Density Residential as land for primarily high density housing such as residential flat buildings. It also says R2 is generally not suitable adjacent to major transport nodes or larger activity centres, where densities should be higher, which is exactly where an R2 street runs into an R3 or R4 block.

For a buyer that boundary is the thing to find. An R2 house whose rear neighbour is R4 has, on the map, a residential flat building behind it at whatever height the R4 map allows, and in a low and mid-rise housing area up to 22 metres and 6 storeys within 400 metres of a station. Nothing may be lodged for years; the zone says only that it can be. The same logic applies to E1 Local Centre and MU1 Mixed Use at the end of the street, where shop top housing is the intended use.

1. Open the Spatial Viewer, search the address, and read Land Zoning, Height of Building, Floor Space Ratio and Minimum Lot Size in Search Results. Download the property report.
2. Tick the Land Zoning layer and read the zones of the lots either side, the block behind, the corner and the main road. Note where the zone changes and what the higher zone's height is.
3. Open SEPP Results and check whether the Housing SEPP's low and mid-rise provisions apply; if they do, the R2, R3 and R4 numbers above replace the LEP's for the housing types they cover.
4. Open the LEP's land use table for the zone, via the outward-link icon in the viewer or the council's LEP page, and read Item 2, Item 3 including its last line, and Item 4.
5. Read the section 10.7(2) certificate in the contract and confirm it states the same zone and lists the heritage, bush fire, flood and other notations the viewer only partly shows.
6. Take the higher zone next door to the DA trackers and search it. The zone is the potential; the tracker is what has been asked for.
