New York City Building Violations and Underlying Conditions Program Selections

New York City's Department of Housing Preservation and Development annually designates buildings for its Underlying Conditions Program based on recent mold and water leak violations. The dataset includes building identifiers, geographic coordinates, violation counts, and program status details. It is published by the City of New York and was last updated in April 2026.

Use Cases

• Analyze spatial patterns of building violations by mapping LATITUDE and LONGITUDE coordinates against BOROUGH and COMMUNITY BOARD.
• Correlate TOTAL_UNITS and CURRENT_STATUS with violation history to identify factors influencing program selection.
• Track the timeline of enforcement actions by analyzing ORDER_ISSUE_DATE and CURRENT_STATUS changes over time.
• Assess violation severity distribution across neighborhoods using BBL and CENSUS TRACT for aggregated reporting.

Strengths

• Contains precise geospatial identifiers including LATITUDE, LONGITUDE, BIN, and BBL for location-based analysis.
• Includes multiple administrative and political district codes such as COMMUNITY BOARD, COUNCIL DISTRICT, and NTA for cross-referencing.

Limitations

• Sample data and total row count are unavailable, preventing assessment of dataset scale and representativeness.
• The dataset scope is limited to buildings selected for a specific New York City program, introducing geographic and regulatory bias.
