Find my boundaryA property boundary is the legal line that marks the extent of a land parcel. In New South Wales, every lot has a unique lot-on-deposited-plan reference (for example, Lot 1 DP 123456) recorded in the NSW cadastre. The boundary is the spatial representation of that legal description - it tells you exactly where your land starts and stops.
People commonly need to find their boundary when planning a fence or retaining wall, checking building setbacks before a development application, confirming lot area for a renovation estimate, or assessing a property during a purchase inspection.
NSW Spatial Viewer (maps.six.nsw.gov.au) is the state government's official mapping tool. It includes cadastral boundaries, but the standard workflow requires you to either pan the map to your area or enter the lot-on-deposited-plan reference. That reference is on the Certificate of Title or a section 10.7 planning certificate - not something most people carry around.
MapMyLot accepts a plain NSW street address. The geocoding matches the address to the correct cadastral parcel and loads the boundary polygon without any lot-plan knowledge. This is particularly useful on-site during a property inspection when you need a quick answer.
The NSW cadastral data in MapMyLot comes from the NSW Department of Climate Change, Energy, the Environment and Water (DCCEEW) via the data.nsw.gov.au open data portal. It covers all 4.89 million lots in NSW - residential, rural, commercial, crown land, and stratum parcels. The data is in GDA94 (EPSG:4283) and is reprojected to WGS84 for display.
The boundary represents the compiled cadastral boundary from government records. It does not show easements, planning overlays, heritage listings, or bushfire risk zones. For those layers, refer to NSW Spatial Viewer or your council's DA mapping tools. MapMyLot gives you the lot boundary from a plain address - quickly, on any device.
Search your street address on MapMyLot and the boundary polygon will appear on the map. No lot number or account is required. The data comes from NSW DCCEEW (data.nsw.gov.au), the official government cadastral dataset covering 4.89 million parcels.
NSW Spatial Viewer is the government mapping portal at maps.six.nsw.gov.au. It has cadastral layers but requires navigating by lot number or panning on a map. MapMyLot accepts a plain street address and shows just the boundary with area and perimeter - faster for day-to-day property checks.
NSW cadastral data is accurate to approximately 1 to 2 metres. It reflects the compiled cadastral register from NSW DCCEEW. For a legally binding determination of a boundary - such as for a fence dispute or development application - you must engage a registered surveyor.
Yes. MapMyLot shows the area of your NSW property in square metres and hectares, and the perimeter in metres, once you search your address. No lot number is needed.
