Fort Bend County, Texas (Katy / Sugar Land / Missouri City, southwest Houston metro, pop. ~880K) serves parcels from a Fort Bend County GIS MapServer sourced from Fort Bend Central Appraisal District (FBCAD). Owner name is OwnerName (the layer display field); owner mailing is OwnerAddress1/2/3 with OwnerCity/OwnerState/OwnerZip; the site address is Situs; identifiers are CAD_Reference_Number (R-number, e.g. R328356) and PropertyNumber. Owner search uses UPPER(OwnerName) LIKE. Verified live 2026-05-30 (OwnerName = Shimmel John). Under Texas Tax Code §25.025, protected persons (peace officers, judges, family-violence victims) may have their owner/address records withheld. MIGRATED 2026-06-06: gisweb.fortbendcountytx.gov was decommissioned (Cloudflare 522) -- the public service moved to gisportal.fortbendcountytx.gov InteractiveMap/Parcels_Public/FeatureServer/1 (ArcGIS 11.3, 359,954 parcels; OwnerName search re-verified live). Field names dropped underscores (CAD_Reference_Number is now CADReferenceNumber).

Fort Bend County's Parcels layer exposes owner names (Owner Name) and address fields (Situs 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 FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-06-06.
/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.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 Fort Bend County actually publishes, not what you might expect from a national standard (there isn't one).

gisportal.fortbendcountytx.gov serves Fort Bend County, Texas 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 Fort Bend County's FeatureServer layer on 2026-06-06. 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.
Fort Bend County's layer is hosted by the county on gisportal.fortbendcountytx.gov. Public ArcGIS endpoints rarely rate-limit individual reads, but gisportal.fortbendcountytx.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.
