Chicago Ordinance Violations with Geospatial and Hearing Details

Violations filed with the Chicago Department of Administrative Hearings, updated daily with the most recent case status. The dataset includes columns for VIOLATION DESCRIPTION, HEARING DATE, CASE DISPOSITION, IMPOSED FINE, and geospatial fields like LATITUDE, LONGITUDE, and WARD. It is published by data.cityofchicago.org and currently lists violations issued by the Department of Buildings.

Use Cases

• Geospatial analysis of violation density using LATITUDE, LONGITUDE, and WARD (from 29 available columns).
• Predicting CASE DISPOSITION or IMPOSED FINE based on VIOLATION CODE, ISSUING DEPARTMENT, and HEARING DATE.
• Temporal trend analysis of violations over time using VIOLATION DATE and HEARING DATE.
• Linking respondent entities to addresses using RESPONDENTS, ADDRESS, and DOCKET NUMBER.

Strengths

• Updated daily with the most recent case status, as noted in the description.
• Includes 29 columns covering administrative, geospatial, and financial aspects of violations.
• Provides explicit geospatial coordinates (LATITUDE, LONGITUDE) and administrative boundaries (WARD, Community Areas).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or departmental bias, as it currently only includes violations from the Department of Buildings.
• Description metadata is limited; actual data quality requires manual inspection after download.
