US Parcel Layer — The Landrecords.us Nationwide Parcel Dataset

The Landrecords.us National Parcel Dataset is a comprehensive, standardized geospatial dataset aggregating ~157 million parcel boundaries and their associated land-ownership and taxation attributes, harmonized from thousands of local jurisdictions across the United States into a single national schema.

Each record is a land parcel: a polygon representing the boundary of an individual tract of land as delineated for tax-assessment purposes by the jurisdiction in which it resides, together with ~94 standardized attributes describing that parcel. Geometries are derived from digitized cadastral maps, surveys, recorded deeds, and legal descriptions.

This dataset redacts property ownership details.

Dataset Creation

Source Data

Parcel geometries and attributes are aggregated from county and municipal tax-assessor offices, planning departments, and GIS departments across the United States. The raw source data is ingested, harmonized to the common schema above, and validated. Locality-specific codes (e.g., zoningcode, usecode) are mapped to standardized categories where possible and otherwise retained in their original form.

Precision & Processing

—Source precision varies with the original survey method vs. digitization from aerial imagery; there is no standardized way to ascertain per-county source accuracy.
—Output geometry is snapped to a 1e-7 uniform grid (~1 cm at most North American latitudes) and reprojected from source NAD83 to WGS 84 output; the datum transformation is typically accurate to within one meter but varies by latitude.
—Some structural attributes (numunits, numfloors) are estimated where direct source values are unavailable and confidence is high.

Bias, Risks, and Limitations

—Attribute completeness varies by jurisdiction. Many NULLABLE fields are sparsely populated because thousands of independent authorities publish different attribute sets.
—`lrid` identifies a parcel across space but not perfectly across time — subdivisions and boundary changes can break lineage between quarterly versions.
—Personal information: ownership fields (ownername, owner* mailing address) originate from public records and may include the names/addresses of individuals. Handle in accordance with applicable privacy law and the non-commercial license terms.
—Standardized codes are best-effort mappings; verify against the originating jurisdiction for authoritative or legal use.
