NSW Block Report FAQs
Common questions about the NSW Block Report. A fast site analysis tool for New South Wales properties that brings together lot boundaries, zoning, floor space ratio, height limits, minimum lot size, heritage, bushfire, flood and landslide layers, and contours - all in one map.
Is the information in the NSW Block Report accurate and up to date?
The data is sourced directly from official NSW Government services: cadastre and imagery from NSW Spatial Services (SIX Maps), planning controls, heritage and hazard layers from the NSW Planning Portal, and elevation from the NSW Spatial Portal. Contours and building outlines should be treated as approximations only. This report is intended as a preliminary site analysis tool. The information should not be relied upon for final design, construction, or legal purposes. A survey by a registered surveyor is required before commencing formal plans or any works on site.
What information is included in the NSW Block Report?
The report includes: lot details (lot number, Deposited Plan, section, lot area), land zoning, floor space ratio (FSR), maximum height of buildings, minimum lot size, heritage listings, bushfire prone land, flood planning areas, landslide risk land, road-reserve edges, adjacent lots, and approximate 2m contours. Where available, an outline of buildings on the lot and adjacent lots is also included.
How do I search for a property?
You can search two ways: by street address, or directly by Lot and Deposited Plan (DP) number using the "Search by Lot & DP" toggle. Because many NSW streets share the same name across different suburbs, an address search may return a list of matches - just pick the correct suburb from the list.
How do I check planning controls like FSR, height and minimum lot size?
These controls are retrieved automatically from the relevant Local Environmental Plan (LEP) maps on the NSW Planning Portal and shown in the Planning section of the lot details. Floor space ratio, maximum building height and minimum lot size are the key figures used to assess what can be built on a site.
How do I check if a property is heritage listed or affected by a hazard?
The report automatically searches for heritage listings and for bushfire, flood and landslide hazards. If one is found, an alert icon appears on the map and it is listed in the lot details. You can cross-check with the NSW Planning Portal Spatial Viewer and the NSW Heritage database.
Why do some properties show "Not mapped" for flood or landslide?
Flood planning and landslide risk maps are only published for some councils (LGAs) on the NSW Planning Portal. A "Not mapped" result means that council has not published that layer to the portal - it does not necessarily mean the property is free of that risk. Bushfire prone land, by contrast, is mapped across the whole state. Always confirm hazard information with the relevant council.
Is the NSW Block Report free to use?
Yes - the NSW Block Report is free to use. Enter an address or Lot/DP, fetch the details, and review the lot boundaries, planning controls, heritage, hazards and contours all in one place.
Can I use the NSW Block Report for commercial projects?
Yes - the NSW Block Report is suitable for building designers, architects, landscape architects, town planners and other construction professionals as a preliminary site analysis tool. It provides a fast, consolidated view of lot boundaries, zoning, planning controls, heritage, hazards and contours, helping to quickly assess a site before commencing formal plans.
