Take it when
Everything the Shapefile is bad at: long attribute names, UTF-8 owner names, files over 2 GB, and several layers in one artefact.

Older ArcMap installations and some legacy county workflows cannot read it. It is a binary database file, so it does not diff.

Counties available as GeoPackage
Nothing is published as GeoPackage yet. Every dataset here is converted on publish, so this fills in as the catalog grows.
Other formats
shp
Shapefile
The format every desktop GIS reads without being asked, and the one most county assessors still publish.
geojson
GeoJSON
Plain text, WGS84, readable in a browser and in a code review. The web's parcel format.
csv
CSV
The attribute table with the geometry left behind — parcel IDs, owners, addresses, valuations.
parquet
GeoParquet
Columnar, compressed, and typed. Built for reading one column of ten million parcels rather than one parcel at a time.
