“Boundary data is a useful and often necessary complement to the foundational tax, deed, mortgage and neighborhood data in the ATTOM Data Warehouse,” said Rob Barber, CEO of ATTOM Data Solutions. “We’ve made some key strategic moves over the past few months to obtain the best boundary data available and fully integrate it into our data warehouse so that we can provide a one-stop shop for clients that want to combine these datasets.”

The parcel boundary data is available in a bulk file format adhering to the industry standard ESRI shape data. ATTOM offers two versions of the parcel boundary data: An Essential version that includes the shape file data for the parcel boundaries along with basic tax assessor information for each parcel; and the Plus version with additional assessor information for each parcel including beds, baths, square footage, year built, lot size, most recent sale date and amount, and much more.

“We’ve included basic assessor property data in our standard parcel boundary file because most use cases benefit from some level of assessor data,” said Todd Teta, chief technology officer at ATTOM Data Solutions. “We also include our unique ATTOM ID for every parcel so that additional data from the ATTOM Data Warehouse such as sales history, mortgage and foreclosure data, or natural hazard risk can easily be joined with the parcel boundaries.”
