Data was last updated in November 2025.
Use Cases
- Analyze the distribution of CountedRentalUnits versus CountedHomeownershipUnits by Borough or Community Board.
- Model spatial clustering of subsidized projects using Latitude, Longitude, and Census Tract.
- Estimate building density and capacity by correlating Stories and BaseSquareFootage with TotalBuildingUnits.
- Join with other housing datasets using key identifiers like BIN, BBL, or ProjectID.
- Assess reporting compliance and construction trends by filtering on ReportingConstructionType.
Strengths
- Includes precise geospatial coordinates (Latitude, Longitude) for mapping.
