https://services2.arcgis.com/1UvBaQ5y1ubjUPmd/arcgis/rest/services/Tax_Parcels/FeatureServer/0Field by field, whether any endpoint we index for Pierce 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 | Not published | Pierce County's public parcel data has no taxpayer name field. The county's layer metadata says the Tax Payer Name attribute is removed from public requests and cites RCW 42.17.260(9). This records the county's own claim; the statute itself was not reviewed here. RCW 42.17.260(9) Stated by Pierce County. Where to request it. |
| Owner mailing address | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| 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 | Answered | Documented in a field list on an endpoint we index. Not every row is populated. |
| 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. |

Pierce County, Washington (FIPS 53053; Tacoma). The county publishes its tax parcels on ArcGIS Online as Tax_Parcels FeatureServer layer 0 (owner PCWA_OpenData): 340,158 rows on 2026-11-01, including condo units in 3D; the county's own query for one row per parcel (TaxParcelType = 'Base Parcel' OR TaxParcelType = 'Tax Purpose Only' OR Land_Acres > 0) returns 328,958. NO TAXPAYER NAME: the county's metadata says the Tax Payer Name attribute is removed from public requests per RCW 42.17.260(9), so owner search is not offered. The layer does carry the taxpayer MAILING address: Delivery_Address (street), City_State (mailing city and state, NOT the site city) and Zipcode. Site_Address has no city of its own and reads 'Undetermined Situs' on unaddressed land. Business_Name (43,370 rows) is, in the county's metadata, '(Business Name) A commercial property business name, or mobile home park name. The field is populated and maintained by the commercial appraisers.' The same metadata adds: 'Business names are determined by the appraiser and may be set to be the parcel owner, rather than the name of a strip mall or a specific business.' Also Use_Code, Landuse_Description, Land_Acres, Land, Improvement and Taxable values, Tax_Area_Code, Exemption_Code, Legal_Description. EditDate max 2026-10-29. CORS open (*). Terms: the Pierce County GIS Data Terms of Use (May 29, 2026) make the data free on condition that users pass the county's no-warranty disclaimers to their end users and do not present products as county products or use the county logo; no commercial or resale restriction.

Pierce County's Tax Parcels layer exposes a parcel identifier (Parcel Number (10 digits, text)) and address fields (Situs Address). Use it for address-to-PIN lookups and identifier queries. 2 of 13 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 2026-11-01.

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

services2.arcgis.com serves Pierce County, Washington 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 Pierce County's FeatureServer layer on 2026-11-01. 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.
Pierce 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.
