Planning, housing, and policy
Measure residential and commercial property, land use, building age, values, and sales across neighborhoods, corridors, and program areas.
For government and public-sector teams
Property data for planning, policy, and public operations
Use nationwide parcel, ownership, assessment, tax, sales, property characteristics, land, and boundary records as a common reference for planning, infrastructure, emergency response, research, and public services.
A common property baseline for public-sector work
Use the same standardized property record across programs and jurisdictions while retaining stable identifiers, local values, and source links.
Federal, state, and local planning, assessment, public works, emergency management, housing, economic development, research, and data teams.
- Coverage
- Nationwide parcels for federal, state, county, municipal, district, or project-area analysis.
- Property context
- Boundaries, addresses, ownership, land use, property characteristics, building footprints, sales, assessments, taxes, exemptions, and districts.
- System handoff
- Bulk files and APIs for GIS, warehouses, models, internal applications, public search, and research tools.
Where property data supports public work
Use one property layer across planning, field operations, analysis, and public services.
Infrastructure and emergency response
Connect parcel boundaries, addresses, property characteristics, building footprints, districts, and FEMA zones to routes, service areas, capital projects, or incident areas.
Assessment and record administration
Compare classifications, values, taxes, exemptions, and parcel identifiers across jurisdictions while retaining each county’s published record.
Research and public services
Support property and ownership research, record verification, application prefill, constituent search, and investigative research.
Use a national baseline without losing the source record
Each standardized record keeps stable identifiers, the county’s published values, and source links for verification. Agencies remain responsible for official determinations and program decisions.
