Note: For questions related to a specific violation or code requirements, please contact the department that issued the violation notice. For questions regarding the hearings process, a hearing date, or a hearing disposition, please contact the Department of Administrative Hearings. Contact information can be found under "Government" at the top of https://www.chicago.gov. For questions related to using the dataset, please use the Contact Dataset Owner button below.

List of ordinance violations filed with the Department of Administrative Hearings. This data set reflects violations brought before the Chicago Department of Administrative Hearings. It does not reflect violations brought before the Circuit Court of Cook County. Each row of data represents a unique violation. Multiple violations may be associated with a single case. The most recent status of the case is shown in the dataset and is updated daily. Hearing date corresponds to the date of the most recent hearing. Each case often consists of multiple hearings and may encounter continuances due to various circumstances before a final disposition is rendered. The case disposition, date of the disposition, and any applicable fines and administrative costs are listed when the case is fully completed. The latest hearing status or disposition reflects the condition of the property at that time and may not reflect the current condition of the property. When multiple respondents are cited, each respondent is separated by a pipe ("|") character. Respondents sometimes are added to cases for technical legal reasons so are not necessarily the parties believed to have committed the violations. This dataset currently lists violations issued by the Department of Buildings. Additional ordinance violations will be added over time. Therefore, it is advisable to use the department-specific filtered view listed under the More Views button for purposes that require only one department's violations.

The program described below ended in 2019. This dataset is being retained for historical reference.

The information displayed represents a de-identified listing of arrest data from August 1, 2012 to July 31, 2016, that was used by the Chicago Police Department’s Strategic Subject Algorithm, created by the Illinois Institute of Technology and funded through a Department of Justice Bureau of Justice Assistance grant, to create a risk assessment score known as the Strategic Subject List or “SSL.” These scores reflect an individual’s probability of being involved in a shooting incident either as a victim or an offender. Scores are calculated and placed on a scale ranging from 0 (extremely low risk) to 500 (extremely high risk).

Based on this time frame’s version of the Strategic Subject Algorithm, individuals with criminal records are ranked using eight attributes, not including race or sex. These attributes are: number of times being the victim of a shooting incident, age during the latest arrest, number of times being the victim of aggravated battery or assault, number of prior arrests for violent offenses, gang affiliation, number of prior narcotic arrests, trend in recent criminal activity and number of prior unlawful use of weapon arrests.

Please note that this data set includes fields that are not used to calculate SSL, for example, neither race nor sex are used in the Strategic Subject Algorithm. Portions of the arrest data are de-identified on the basis of privacy concerns. The attributes used in the Strategic Subject Algorithm were revised on an ongoing basis during the lifetime of the program.

The full list of buildings required to comply with the Chicago Energy Benchmarking Ordinance. As of 2016, this list includes all commercial, institutional, and residential buildings larger than 50,000 square feet. The information in this dataset should be used by building owners / managers or other building representatives to determine if your property needs to comply by the annual deadline of June 1st. This data can also be used to look up your property's unique 6-digit Chicago Energy Benchmarking ID, which is required for compliance. (The ID is also included the notification letters sent by the City.)

The Energy Benchmarking Ordinance calls on existing municipal, commercial, and residential buildings larger than 50,000 square feet to track whole-building energy use, report to the City annually, and verify data accuracy every three years. The law, which phases in from 2014-2017, covers less than 1% of Chicago’s buildings, which account for approximately 20% of total energy used by all buildings. For more details, including ordinance text, rules and regulations, and timing, please visit www.CityofChicago.org/EnergyBenchmarking.

Note that the ordinance authorizes the City to make individual building data readily-available to the public, beginning with the second year in which a building is covered. The Covered Buildings List is distinct from the publicly-shared energy use data, and does not include energy use or any other information reported in the benchmarking process. For the building-specific energy use dataset, see https://data.cityofchicago.org/d/xq83-jr8c.

If your property is on this list, and you do not believe you are covered by the ordinance, please submit the appropriate online exemption form at: www.CityofChicago.org/EnergyBenchmarking. If your property is not on the list, and it meets the compliance criteria, please check for any alternative building addresses. If the building is still not found, please submit the Building ID Request Form (http://www.cityofchicago.org/city/en/depts/mayor/iframe/Benchmarking_ID_Request.html). The Chicago Energy Benchmarking Help Center can assist with any other questions, and can be reached at (855)858-6878, or by email: Info@ChicagoEnergyBenchmarking.org.

This dataset will be refreshed periodically as additional information becomes available. It is advisable to use the then-current version of any dataset, if possible.

COVID-19 vaccinations administered by COVID-19 vaccine providers in the City of Chicago, as reported by medical providers in Illinois Comprehensive Automated Immunization Registry Exchange (I-CARE). This includes Chicago and non-Chicago residents who were vaccinated at sites in the City of Chicago.

Daily counts are shown for the total number of doses administered, first dose, and second dose, as well as cumulative totals as of that date. Vaccinations are counted based on the day the vaccine was administered.

All data are provisional and subject to change. Information is updated as additional details are received and it is, in fact, very common for recent dates to be incomplete and to be updated as time goes on. At any given time, this dataset reflects data currently known to CDPH.

Numbers in this dataset may differ from other public sources due to when data are reported and how City of Chicago boundaries are defined.

For information about the number of vaccine doses administrated to Chicago residents and number of residents considered fully vaccinated regardless of if they were vaccinated in Chicago, see https://data.cityofchicago.org/Health-Human-Services/COVID-19-Daily-Vaccinations-Chicago-Residents/2vhs-cf6b.

This dataset contains all open 311 reports of one or two lights out on metal poles on a residential or arterial street and all completed requests since January 1, 2011. Whenever CDOT receives a report of a street light outage, the electrician assigned to make the repair looks at all the lights in a group (circuit) to make sure that they are working properly. If two requests regarding the same group are made within 30 calendar days of each other, the newest CSR is automatically given the status of “Duplicate (Open).” Since the electrician will be looking at all the lights in a group to verify that they are all working the “Duplicate (Open)” address will also be observed and repaired. Once the street lights are repaired, the CSR status will read “Completed” for the original request and “Duplicate (Closed)” for any duplicate requests. Data is updated daily.
