Chicago's Building Code Scofflaw Ordinance (Section 2-92-416 of the Municipal Code of Chicago) prohibits the owners of buildings that are identified as "priority buildings with serious and chronic code violations" from being awarded City contracts, receiving financial assistance from the City, or having certain applications accepted or processed by the City. Buildings on the list are also subject to follow-up inspections by the Department of Buildings at least every 12 months, and once removed from the list, continuing inspections until the building receives two consecutive inspections, at least six months apart, during which no serious violations are found. The owners of buildings included on the list are designated as "building code scofflaws."

Pursuant to the ordinance, as amended in 2021, lists of buildings are published on September 1 and March 1 of each year and lists of owners associated with those buildings are published one month later.

The structure of this dataset was modified on 9/1/2021 to be consistent with the amended ordinance.

The Annual Appropriation Ordinance is the final City operating budget as approved by the City Council. It reflects the City’s operating budget at the beginning of the fiscal year on January 1, 2017.

This dataset displays the positions and related salaries detailed in the budget as of January 1. It is extracted from the personnel portion of the Appropriation Ordinance. The dataset presents the position titles (without names) and salaries described in the budget, but does not provide a reflection of the current city workforce with full names and salaries.

Disclaimer: the “Total Budgeted Units” column displays either A) the number of employees AND vacancies associated with a given position, or B) the number of budgeted units (ie. hours/months) for that position. “Position Control” determines whether Total Budgeted Units column will count employees and vacancies or hours/months. If a Position Control is 1, then employees and vacancies are displayed; if a Position Control is 0, then the total number of hours/months recorded is displayed.

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.
RESPONDENT: The name of the entity issued the code violation notice.
CASE TYPE: The Case Types are historic 3-Day Notice, Air Pollution Defect Notice, Administrative Hearing, Summary Abatement, Chicago Storage Tank NOV, State Administrative Citation, State Violation Notice, historic Pre Enforcement Conference, and historic Ticket-Municipal Prosecution.
VIOLATION DATE: The date of the code violation.
CODE VIOLATION: This refers to the municipal or state code violation being cited in the ticket.
DISPOSITION: The outcome of the code violation.
CASE STATUS: This refers to the final or most current status of the case.
FINE AMOUNT: This is the total fine assessed for the case not including court fees. Note that for the Historic Department of Environment data, this value is not unique to the record but applies to the entire case. For example, the case with a Docket No of 07DE000171 has two records with a fine amount of $350 in each record. The total fine on the case is $350, not the sum of $700.
COMMENT: Additional information relating to the violation or case.
DATA SOURCE: The city department that collected the data.

This dataset is historical only and ends at 5/7/2021. For more information, please see http://dev.cityofchicago.org/open%20data/data%20portal/2021/05/04/covid-19-testing-by-person.html.

For all datasets related to COVID-19, see https://data.cityofchicago.org/browse?limitTo=datasets&sortBy=alpha&tags=covid-19.

This dataset contains counts of people tested for COVID-19 and their results. This dataset differs from https://data.cityofchicago.org/d/gkdw-2tgv in that each person is in this dataset only once, even if tested multiple times. In the other dataset, each test is counted, even if multiple tests are performed on the same person, although a person should not appear in that dataset more than once on the same day unless he/she had both a positive and not-positive test.

Only Chicago residents are included based on the home address as provided by the medical provider.

Molecular (PCR) and antigen tests are included, and only one test is counted for each individual. Tests are counted on the day the specimen was collected. A small number of tests collected prior to 3/1/2020 are not included in the table.

Not-positive lab results include negative results, invalid results, and tests not performed due to improper collection. Chicago Department of Public Health (CDPH) does not receive all not-positive results.

Demographic data are more complete for those who test positive; care should be taken when calculating percentage positivity among demographic groups.

All data are provisional and subject to change. Information is updated as additional details are received.

This dataset reflects the daily volume of violations created by the City of Chicago Red Light Program for each camera. The data reflects violations that occurred from July 1, 2014 until present, minus the most recent 14 days. This data may change due to occasional time lags between the capturing of a potential violation and the processing and determination of a violation. The most recent 14 days are not shown due to revised data being submitted to the City of Chicago during this period. The reported violations are those that have been collected by the camera system and reviewed by two separate City contractors. In some instances, due to the inability the registered owner of the offending vehicle, the violation may not be issued as a citation. However, this dataset contains all violations regardless of whether a citation was actually issued, which provides an accurate view into the Red Light Program. Because of occasional time lags between the capturing of a potential violation and the processing and determination of a violation, as well as the occasional revision of the determination of a violation, this data may change. More information on the Red Light Program can be found here: http://www.cityofchicago.org/city/en/depts/cdot/supp_info/red-light_cameraenforcement.html. The corresponding dataset for speed camera violations is https://data.cityofchicago.org/id/hhkd-xvj4.
