St Clair (N. Congressional District) County Mapping / GIS

St. Clair County, Alabama maintains a public GIS/mapping system through the Revenue Commissioner's office, accessible via the county's ArcGIS portal ("St. Clair County Maps") and the St. Clair County Parcel Map Viewer web app. The public can freely view parcel boundaries, owner names, parcel/PIN numbers, acreage, and aerial imagery, and search by owner, parcel number, or address. The mapping data is served from the county's own ArcGIS Server (map.stclairco.com), whose public parcel viewer service confirms it as the "St. Clair County Alabama, public parcel viewer." No login or payment is required for map viewing.
