ATTOM, a leading curator of land, property, and real estate data, is pleased to announce it has added yet another new data product to the ever-expanding ATTOM Table of Data Elements – Building Footprints. ATTOM’s Building Footprint data covers 187 million building outlines nationwide for all property types. Using advanced proprietary AI algorithms, it accurately captures the shape and perimeter of structures for enhanced planning and analysis.
ATTOM provides the nation’s premier unified geospatial boundary products for hyperlocal search, map display and visualization, data enrichment, and other geospatial analyses. The integration of building footprints, which are polygons outlining a building’s ground-level perimeter, supports various mapping and analytic use cases in insurance, real estate markets, and other key industries.
By geospatially matching ATTOM’s Building Footprint data with respective parcel boundaries, we ensure a detailed and precise mapping that harmonizes the actual dimensions of buildings with their legal land divisions. This precise coordination is essential for various industries. In insurance, it assesses risk and costs by identifying building locations. Real estate links footprint boundaries to property details, enhancing assessments. Government agencies use it to evaluate development limitations, property values, urban growth, and plan infrastructure like EV charging stations. Home services optimize rooftop solar installations and telecom deployment. The mortgage industry improves underwriting accuracy and pricing by assessing natural hazards. Marketing benefits from accurate location-aware experiences and notifications using precise building footprints.
“With the addition of Building Footprints to our database, ATTOM is enhancing real estate, insurance, and urban planning with precise, AI-driven property outlines,” said Todd Teta, CTO at ATTOM. “This accuracy enables improved risk assessment, more precise property valuations, and smarter infrastructure planning—empowering existing applications and paving the way for new use cases for ATTOM’s customers.”
