Free parcel data in New Jersey
Yes. New Jersey publishes a free statewide parcel layer: Parcels and MOD-IV Composite of NJ (Web Mercator), from NJ Office of Information Technology, Office of GIS (NJOGIS). Coverage: All 21 counties. It's a public ArcGIS REST service with no API key or login.

Notes for GIS users
PAMS_PIN = '<4-digit muni code>_<block>_<lot>[_<qualifier>]', e.g. 1111_2001_1. A user's block/lot can also match PCLBLOCK + PCLLOT within PCL_MUN. Some parcels have no MOD-IV match, so attributes (COUNTY, PROP_LOC) can be null.
How to use it
- QGIS: Layer > Data Source Manager > ArcGIS REST Server, add a connection with the service URL (the endpoint above without the
final
/0), then add the layer. Filter to your area before exporting. - ArcGIS Pro: Add Data > Data From Path, paste the endpoint.
- Direct query: append
/query?geometry=LON,LAT&geometryType=esriGeometryPoint&inSR=4326&spatialRel=esriSpatialRelIntersects&outFields=*&f=geojsonto get the parcel at a point. - CAD: see getting a parcel into AutoCAD or Civil 3D.
Assessor parcel lines are for taxation and are often 5 to 50 ft off the legal boundary. Why.
Basesheet uses this to draw the parcel line on a base plan for any New Jersey address, with LiDAR contours, soils, flood zones and wetlands.
