BuyParcelData API

Nationwide parcel data covering ownership, valuations, zoning, tax records, and more via a simple REST API.

What is BuyParcelData?

BuyParcelData (BPD) provides parcel data for every county in the United States. The dataset covers 160 million parcels, representing 100% of US land area and 100% of the US population, sourced directly from county assessors, not inferred or aggregated from third parties.

Each parcel record includes 100+ fields: ownership, assessed value, sale history, zoning, tax records, land use, boundaries, and enriched data from external sources including USDA Cropland Data Layer, elevation, and adjacent acreage under the same ownership.

How it works

1. Find parcels by geography: submit a GeoJSON polygon to POST /parcels/area. BPD returns the UUIDs of every parcel whose geometry intersects your area.
2. Fetch records: pass those UUIDs to POST /parcels/query to retrieve full parcel records, or query by any field directly without a geography step.
3. Point lookup: use GET /parcels/point to find the parcel at a specific lat/lng.
