https://mapping.adamscountypa.gov/arcgis/rest/services/AGOL/Parcel_Owners/MapServer/0Field by field, whether any endpoint we index for Adams 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 | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| Owner mailing address | Not published | Adams County's public Parcel_Owners layer (MapServer layer 0) has no owner mailing-address column: its fields are the parcel id, owner name, situs, municipality, lot, acreage, subdivision, deed, sale and value columns. The county's CAMA_Parcels service has address columns but is marked for internal use only, so it is not used. 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. |

Adams County, Pennsylvania (county seat Gettysburg; FIPS 42001). Served by Parcel_Owners MapServer layer 0 on the county's own server (mapping.adamscountypa.gov), the parcel layer of the county's public Adams County Tax Parcel Viewer; the service describes itself as a 'Public parcel service depicting the parcel lines and limited tax information maintained by the Adams County Tax Services Department'. Read 2026-11-02 by metadata and returnCountOnly only: 46,935 parcels; SHORT_NAME (the layer's 'Owner') and COMBINED_SITUS (its 'Location') are each populated on 46,677, Parcel_ID on 46,933. maxRecordCount 2000, pagination supported, capabilities Map, Query and Data (no editing), and the server echoes the caller's Origin in Access-Control-Allow-Origin. The sample query is an owner search verified 2026-11-02 at 737 rows with returnCountOnly. THIS LAYER HAS NO OWNER MAILING ADDRESS: it lists no mailing column, so owner_mailing_address is not published. NOT USED: the county's CAMA_Parcels service, which carries ADDRESS_2, CITY, STATE and ZIP but whose web map is labelled 'For internal use only by employees of Adams County, Pennsylvania'; the PASDA copy (pasda/AdamsCounty MapServer layer 2), which has no owner field; and the county's Parcel_Owners FeatureServer, whose capabilities advertise Create, Update, Delete and Editing (the county may want to be told; nothing was sent). The layer also carries Comment_1 and Comment_2 free-text columns, which are not listed, and the value columns LAST_MAILED_TAXABLE_LAND, LAST_MAILED_TAXABLE_BUILDING and LAST_MAILED_TAXABLE_TOTAL, which are not listed either: their names contain 'MAIL', so the field classifier would read a dollar amount as the owner's mailing address. TERMS: the Tax Parcel Viewer item says the application was 'generated and published for illustrative purposes only' and that parcel boundaries may not be relied on as a surveyed line; it states no commercial-use or resale limit and no licence, so the licence is recorded as unknown. NOT CONFIRMED: SHORT_NAME may be a shortened form of the owner of record (the name suggests it; no row was read), the Parcel_ID format, and whether COMBINED_SITUS includes the municipality.

Adams County's Parcel_Owners layer exposes a parcel identifier (Parcel ID), owner names (Owner Name), and address fields (Location (Site Address)). Use it for owner-name lookups and address-based parcel searches. 4 of 6 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-11-02.

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 Adams County actually publishes, not what you might expect from a national standard (there isn't one).

mapping.adamscountypa.gov serves Adams County, Pennsylvania 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 Adams County's MapServer layer on 2026-11-02. 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.
Adams County's layer is hosted by the county on mapping.adamscountypa.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but mapping.adamscountypa.gov 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.
