Thurston County's data terms don't allow sites like ours to show its parcel data, so we don't index it. If you'd like this to change, ask the county at GeoData@thurstoncountywa.gov.

How to find an ArcGIS parcel layer URL

Notes

Thurston County (Olympia, Lacey, Tumwater; FIPS 53067) parcel data is published by the Thurston County GeoData Center. The atlas lists no endpoint for Thurston: the endpoint was retired on 2026-10-20 after the county's reply of 2026-10-19 set out its data terms as non-negotiable. Term 8 bars making the data available to third parties naming Thurston County as the source, and term 10 bars commercial owner mailing lists. The terms are published at https://www.thurstoncountywa.gov/map-viewer-disclaimer/disclaimer-data. Owner names were never on the county's public layer; the mailing address was. If you would like this service, contact the county at GeoData@thurstoncountywa.gov and ask it to allow it.

Using this endpoint

What Thurston County publishes

Thurston County does not yet have a verified public REST endpoint in our atlas. The sections below cover patterns common to most county parcel APIs.

Two paths from URL to result

Open in Parcel Lookup: click the button on the endpoint card. The lookup tool loads the layer, auto-detects fields, and gives you a search box. No code, no API keys, just a browser.
Query directly: append /query?where=…&outFields=*&f=jsonto the URL. The sample query above is a working example you can paste into a browser tab to see the raw JSON response.

Why field names vary by county

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

For background, see What is an APN?

What to do with the results

Generate a public-notice mailing list: pipe the parcel layer URL into Radius Notice to buffer around an address and select neighboring owners.
Print Avery 5160 labels: export the result CSV and drop it into CSV → Labels.
Pull individual parcel records: use Parcel Lookup directly to grab zoning, assessed value, and ownership for one property at a time.
