New Jersey County GIS Websites: Parcel Viewers by County

Which parcel map software each New Jersey county uses (21 of 21 verified), how to search the common viewers, and a link to every official map.

Looking for New Jersey county GIS websites? New Jersey has 21 counties, and their official parcel maps do not all run on the same software. Knowing which viewer a county uses tells you what the search box expects and where the parcel report is.

New Jersey does not run one statewide parcel map that every county uses. Each local government picks its own viewer, so the screen you see in one county can look nothing like the one next door. This guide sorts all 21 New Jersey entries in the Platbookmapper directory with the software behind each official map.

New Jersey at a glance

4 of these entries point to a statewide viewer rather than a county-run site (NJ Parcels and MOD-IV Composite layer in ArcGIS Map Viewer (imagery basemap)). A statewide map is handy for crossing county lines, but the local office is still where deeds and tax records are kept.

The most populous counties

The busiest offices are worth knowing first, since most searches land there.

How to search the most common viewers in New Jersey

county web map (8 entries, e.g. Bergen County, Camden County, Cape May County)

  1. Open the county's own web map.
  2. Search for the property or pan and zoom to it.
  3. Click the lot to bring up what the county publishes about it.
  4. Look for print or measure tools if you need a quick map or rough size.

ArcGIS Experience Builder (6 entries, e.g. Burlington County, Hunterdon County, Monmouth County)

  1. Open the link. This viewer is an ArcGIS Experience Builder app, so its layout is custom to the publisher.
  2. Look for a search box or search widget and type in a street address or parcel ID.
  3. Click a parcel to see its details in a pop-up or side panel.
  4. Check the toolbar for a layer list or basemap switcher if you want aerials or other layers.

ArcGIS Map Viewer (5 entries, e.g. Atlantic County, Essex County, Middlesex County)

  1. Open the official map link from the county's page. The map opens in Esri's ArcGIS Map Viewer in a new tab.
  2. Type an address or place name into the search box at the top, or drag and zoom the map yourself.
  3. Click inside a parcel outline. A pop-up lists whatever attributes the publisher shares, such as a parcel ID or acreage.
  4. Open the Layers panel to hide or show parcels, and use the Basemap button to switch to aerial imagery.

Before you rely on what you find

Online parcel lines are drawn for tax mapping, not surveys, so they can sit a few feet off the real boundary. For anything legal, such as a fence, a sale or a dispute, use the recorded deed and a licensed surveyor. To check flood zones, soils or wetlands for a spot you found, open it on the Platbookmapper Land Map, which pulls FEMA, USDA and U.S. Fish & Wildlife layers.
