Municipal and State code violation notices issued by the Department of Environment (DOE) from January, 1993 to December 31, 2012 and by the Department of Public Health (CDPH) Permitting and Inspections unit since January 1, 2012. On January 1, 2012, the DOE was disbanded and all its inspection, permitting, and enforcement authorities were transferred to the CDPH.
Data fields requiring description are detailed below.
MAPPED LOCATION: Contains latitude/longitude coordinates of the site as determined through the Chicago Open Data Portal’s geocoding engine. In instances where the facility address is a range, the lower number (the value in the “Street Number From” column) is used for geocoding. For example, for the range address 1000-1005 S Wabash Ave, the Mapped Location would be the coordinates for 1000 S Wabash Ave.
DOCKET NO: This the unique identifier assigned to the case. A docket number can contain multiple tickets.
TICKET NO: This is the unique identifier of the issued ticket. A ticket can contain up to two code violations. NOTE that the Department of Environment Ticket No.’s may refer to non-unique violations.
