NYC Housing Maintenance Code Violations with Geospatial and Status Details

Violations issued by the New York City Department of Housing Preservation and Development against rental dwelling units and buildings for conditions violating the Housing Maintenance Code or Multiple Dwelling Law. The base data includes all violations open as of October 1, 2012, and is updated daily with new violations and status changes. Each row contains discrete information for a unique violation, identified by a ViolationID.

Use Cases

• Predict violation class severity (Class) from inspection details (InspectionDate, RentImpairing) and property characteristics (BIN, BBL) using classification models.
• Analyze spatial patterns of housing violations across neighborhoods using Latitude, Longitude, CommunityBoard, and NTA columns.
• Model the timeline from violation issuance to closure using CurrentStatus, CurrentStatusDate, CertifiedDate, and ApprovedDate for time-series analysis.
• Link violation records to other city datasets like building registrations using join keys such as BuildingID, RegistrationID, and BBL.

Strengths

• Daily updates ensure the violation statuses (CurrentStatus, CurrentStatusDate) reflect near-real-time administrative actions.
• Includes precise geospatial identifiers (Latitude, Longitude, BBL, BIN) for location-based analysis.
• Violations are categorized by hazard class (Class A, B, C, I) and linked to specific legal orders (OrderNumber).

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The description notes that an open violation status may not mean the physical condition is uncorrected, introducing potential label noise.
