https://services2.arcgis.com/XVOqAjTOJ5P6ngMu/arcgis/rest/services/Parcels_Composite_NJ_WM/FeatureServer/0Field by field, whether any endpoint we index for Essex County answers it, and the evidence for each. We only call a field restricted when there is a stated reason we can cite. Everything else here is a fact about the services we index, not a claim about the law.
| Field | Status | Basis |
|---|---|---|
| APN | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| Owner name | Restricted | The statewide composite layer's OWNER_NAME column returns no value for any Essex County record, and the NJ Office of GIS states in the service description that the field is redacted per Daniel's Law for public web access. N.J. Daniel's Law Stated by NJ Office of GIS (service description). Where to request it. |
| Owner mailing address | Restricted | New Jersey's Daniel's Law (N.J.S.A. 56:8-166.1) restricts disclosure of the home addresses of judicial officers, law enforcement officers, child protective investigators and prosecutors, and their household family members. The tax-record mailing address on a parcel layer can be a covered person's home address and the layer does not identify which, so UrbanKit Studio leaves owner mailing addresses for Essex County parcels out of every tool, the API and the MCP server. N.J.S.A. 56:8-166.1 (Daniel's Law, P.L.2020, c.125, as amended) Where to request it. |
| Site address | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| Geometry | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| Land use | Not published | No endpoint we index for this county documents this field, so a query cannot ask for it. That is a fact about the services we index, not a legal restriction, and not a statement that the county holds no such record. Where to request it. |
| Zoning | Not published | No endpoint we index for this county documents this field, so a query cannot ask for it. That is a fact about the services we index, not a legal restriction, and not a statement that the county holds no such record. Where to request it. |

Essex County, New Jersey (county seat Newark) is served from the NJ Office of GIS statewide Parcels and MOD-IV composite, Parcels_Composite_NJ_WM FeatureServer layer 0 (Cad_parcel_mod4), the same layer Bergen County uses. Filter with COUNTY='ESSEX': 178,089 of the layer's 3,481,240 rows on 2026-10-04. OWNER_NAME is an empty string on every row statewide: COUNTY='ESSEX' AND OWNER_NAME<>'' returns 0, while the control COUNTY='ESSEX' AND ST_ADDRESS<>'' returns all 178,089. Test it with <>'' because IS NOT NULL passes on the blank strings. The column is deliberately not listed as a search field, because the owner classifier takes the first owner-looking field and would route owner lookups to a blank column. The service description says the field is redacted per Daniel's Law for public web access. Searchable: PAMS_PIN (municipality code, block and lot, e.g. 0707_301_6), PROP_LOC (property location), MUN_NAME. The layer also carries mailing-address columns (ST_ADDRESS, CITY_STATE, ZIP_CODE) that UrbanKit Studio does not request, search, list or return (see ownerFieldNote). Property class, land, improvement and net values, acreage, the last sale, year built (filled on 156,919 rows on 2026-10-04) and building description (121,070) come from MOD-IV. CORS is open (Access-Control-Allow-Origin: *), maxRecordCount is 2000 and the layer is Web Mercator. The item's licence text is a disclaimer that requests acknowledgement of NJOGIS and points to the State's conditions of use. Countywide shapefiles and the MOD-IV tax list are downloadable from NJGIN. Third-party Essex_County_Parcels copies on ArcGIS Online carry no owner column and are not registered. Verified live 2026-10-04: COUNTY='ESSEX' AND PROP_LOC LIKE '%BROAD%' returned rows (first PAMS_PIN 0707_301_6, 54 BROADWAY LANE, Fairfield Township).

Essex County's Cad_parcel_mod4 layer exposes a parcel identifier (PAMS Parcel Identifier (MUN_BLOCK_LOT)) and address fields (Property Location / Address). Use it for address-to-PIN lookups and identifier queries. 3 of 11 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-10-04.

The sample query above is a working example you can paste into a browser tab to see the raw JSON response.Counties publish parcel data through their own ArcGIS Server installations, each with its own schema. One county uses APN, another uses PIN, a third uses PARCEL_ID. Some expose owner names; others keep them on a separate assessor's portal. The searchable fields list above reflects what Essex County actually publishes, not what you might expect from a national standard (there isn't one).

services2.arcgis.com serves Essex County, New Jersey parcels over public ArcGIS REST, but, like most county servers, it may not send the CORS headers a browser needs for a cross-origin fetch. If a direct browser call fails, the layer still works from curl, Postman, or a server-side script; the UrbanKit parcel lookup tool proxies the request, so a search that succeeds there confirms the layer is genuinely public.
We last verified Essex County's FeatureServer layer on 2026-10-04. County GIS teams move services without notice, so if you hit a fresh 404, tell us and we'll re-check. Atlas entries are re-verified on a rolling basis.
Essex County's layer is hosted on Esri ArcGIS Online. Public ArcGIS endpoints rarely rate-limit individual reads, but services2.arcgis.com can throttle heavy automated traffic at the host level. Page through results with resultOffset / resultRecordCount and request only the fields you need. There's no API key and no charge from the county.
