111 of 820 fields. Returned by the API and in bulk. Any county-sourced value that is absent remains null. Normalized, computed, and enrichment fields are labeled separately.
Enrichments
Context joined to the parcel
Enrichment fields are labeled separately from county-published values, so downstream users can tell them apart.
Contiguous acreage, same owner
How much adjoining land the same owner already holds. One number that turns a parcel list into an assembly, siting, or leasing target list.

Structure geometry with measured height and estimated floor count. Opt in with include_buildings — it costs no additional credits.
build_idheightheight_varianceestimated_floorsgeomFEMA flood zones
The official FEMA zone designation and subtype for the parcel — the published zone label, not a modeled risk score.
