Property Data for GIS & Mapping

Building maps or spatial models? Every record carries lat/lng, county FIPS, and where available a parcel APN.

What GIS & mapping teams need

GIS teams need geocoded rows and join keys. Each property includes latitude and longitude, a 5-digit county FIPS code, and a parcel APN where available — enough to map points or join to parcel and boundary layers.

Get it in two ways

Bulk download — grab the whole United States or a single state, county, or ZIP as Parquet or CSV, free and CC0. Best for analysis over many properties at once.

Live API — every row carries an id that's a live endpoint on Straply, for one-property lookups and always-current data.

A practical tip

Filter a state Parquet to the bounding box you need, then join on county FIPS to your boundary shapefiles, or on APN to assessor parcels.

See the data dictionary for every field, or start with how to download.
