Chicago Building Violations

$179 / year

This dataset shows the violations issued by the Department of Buildings from 2006 to the present for the City of Chicago.


In this dataset each record is a building inspection conducted by the City of Chicago Department of Buildings, and each inspection has one or more violations. Inspections are made because of complaints, periodic inspections, and the opening of new buildings or businesses. These data are historical in nature and should not be relied upon for real estate transactions. For transactional purposes such as closings, please consult the title commitment for outstanding enforcement actions in the Circuit Court of Cook County or the Chicago Department of Administrative Hearings. Violations are always associated with an inspection and there can be multiple violation records to one inspection record.

The dataset contains cases where a respondent has been found to be liable as well as cases where the respondent has been found to be not liable.

Property_GroupProperties (lots) in the City of Chicago can typically have multiple point addresses, range addresses and buildings. Examples are corner lots, large lots, lots with front and rear buildings, etc.. As a result, inspections (and their associated violations), permits and complaints related to a single property could have different addresses. This problem can be reconciled by using Property Group. All point and range addresses for a property are assigned the same Property Group key.integerlevel : Nominal
