19,685 parcels carry no improvement value on the St. Clair County tax roll as of 2026-11-01. After removing rights-of-way, slivers, utility strips and parcels that already have a structure by the federal building footprints, 17,378 are buildable land totalling about 217,127 acres.
9% of buildable parcels touch a FEMA special flood hazard area (zones A, AE or similar). 91% are entirely in Zone X, the minimal-risk designation. Mapped wetlands appear on 4%.
Septic needs a county health department permit and a soil evaluation on the actual site. As a screen, 98% of buildable parcels sit on soils the USDA survey classes as well drained or better. Hydric soils, which usually fail, appear only as small inclusions along creeks and bottomland here; the survey does not map a mostly-hydric unit under any buildable parcel.
Alabama records sale prices with the deed, but there is no searchable database of them. The county's appraised land value per acre, which is what LandScout shows, has a median of $5,340 for 5 to 20 acre tracts and $2,842 for tracts over 100 acres. Market prices run higher; appraisal is a floor and a comparison tool, not an asking price.
75% individual, 17% llc, 5% corporation, 2% trust. 14% of owners have a mailing address outside the county.
Parcel boundaries, owners of record and appraised values are from the St. Clair County assessor's GIS. Flood zones are FEMA, slope is derived from USGS elevation, soils are the USDA soil survey, wetlands the National Wetlands Inventory, timber the Forest Service FIA, structures the FEMA USA Structures dataset, and roads, power lines, ponds and developed land OpenStreetMap (© OpenStreetMap contributors, ODbL). Verdicts come from fixed rules applied to those fields, the same rules in every county, and the best-scoring parcels are also checked against a USDA aerial photo by an AI model.
