Kent County (Grand Rapids metro) hosts ParcelsWithCondos/MapServer/0, a countywide parcel layer including condominium units. 22 fields: PPN, TAXPARCEL_FLAG, OWNERNAME1, OWNERNAME2, OWNERCAREOF, OWNERADDRESS, OWNERCITY, OWNERZIPCODE, PROPERTYADDRESS, PROPADDRESSCITY, PROPADDRESSSTATE_ZIPCODE, PROPERTYCLASS, GOVERNMENTALUNIT, SCHOOLDISTRICT, SEV/TAXABLE fields (2 tribunals), ACREAGE, PNUM, geometry. Query confirmed live: UPPER(OWNERNAME1) LIKE '%SMITH%' returns real owner names (e.g., 'SMITH TIMOTHY J & STARKS-SMITH MARY'). Owner mailing address is in OWNERADDRESS/OWNERCITY/OWNERZIPCODE. The county's open data hub at kentcountymi-accesskent.opendata.arcgis.com mirrors the same data. Michigan parcel ID (PPN) format is 10-digit county-township-parcel. INFRASTRUCTURE OUTAGE (verified 2026-06-06): the entire agisprod ArcGIS server is offline ('Could not access any server machines') -- every service and the portal are affected. Looks transient rather than a retirement; recheck around 2026-07-06.

Kent County's Parcels With Condos layer exposes owner names (Owner Name (Primary), Owner Name 2, Owner Address, Owner City) and address fields (Property Address, Property Address City). Use it for owner-name lookups and address-based parcel searches. 7 of 8 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 checked 2026-06-06; currently unreachable.

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

gis.kentcountymi.gov serves Kent County, Michigan 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 Kent County's MapServer layer on 2026-06-06 and it was unreachable on that check. 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.
Kent County's layer is hosted by the county on gis.kentcountymi.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.kentcountymi.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.
