No public REST endpoint we can serve

Iron County's parcel map runs on a proprietary viewer with no public query service, and Michigan has no statewide parcel layer to use instead, so we don't index it. Search the county's BS&A Online portal, or request it and we'll tell you if that changes.

How to find an ArcGIS parcel layer URL

Notes

No public ArcGIS REST parcel layer was found for Iron County, Michigan (county seat Crystal Falls) as of 2026-09-25, re-checked 2026-10-05 (the state ArcGIS server at gisagocss.state.mi.us lists no parcel layer in its OpenData, geographic_framework or boundaries folders; its only parcel-shaped layer is DNR state-owned land). The county's GIS map viewer, linked from its equalization page, runs on Colligo GIS, a proprietary web platform with no documented public query API. Michigan has no statewide public parcel REST layer to fall back on. Parcel and tax records can be searched by name, address or parcel number through the county's BS&A Online portal, which returns no geometry and offers no field-level API. Two same-name ArcGIS parcel applications belong to other states and do not cover this county: Iron County, Utah's 'County Parcel Locator' and Iron County, Missouri's assessment map hosted by the Southeast Missouri Regional Planning Commission.

Using this endpoint

What Iron County publishes

Iron 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 Iron 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.
