Chicago Department of Transportation (CDOT), Division of Infrastructure Management (DIM), operates Chicago’s “One Call” service—known as “811 Chicago.” Per Municipal Code of Chicago (MCC) § 10-21-080, “in the event of damage to any underground facilities, the person responsible for the damage shall immediately notify…811 Chicago.”

811 Chicago records all reported damages as “hit tickets.” This dataset contains hit tickets since January 1, 2020. (Prior to that date, hit tickets data is a less reliable measure of utility damages.)

Please note, a hit ticket does not necessarily mean damage occurred or implicate the parties listed on the hit ticket as having caused the damage. For example, an excavator may report damage they discovered, but did not cause; an entity may incorrectly report the utility that was damaged or who caused the damage; the same damage may be reported by more than one entity. 811 Chicago investigates all reported damages to determine if there was a violation of MCC § 10-21. During the course of its investigation, 811 Chicago will confirm the information on the hit ticket. If 811 Chicago discovers inaccurate information, it may not update the hit ticket. The data related to 811 Chicago’s investigation is not exposed in this data set. Importantly, 811 Chicago does not determine which entity is liable for the damage, and the “hit by” field does not indicate that the individual or entity caused the damage or violated MCC § 10-21.

Prior to 12/12/2022, Owner and Owner Management Agent addresses could not be registered through the registration site so no City, State, or ZIP columns were present in this dataset. Because all previously existing records had Chicago addresses for Owner and Owner Agent, the City and State columns were populated when added to this dataset but ZIP values are only available from 12/12/2022 forward.

The Property Address is always in Chicago.

Map of Safe Chicago Bleeding Control Kit and AED locations.

NOTE, 2/28/2024: This dataset now contains locations of automated external defibrillators (AEDs), in addition to bleeding control kits.

Locations of kits designed to assist City of Chicago employees and members of the public control severe bleeding or attempt to reverse cardiac arrest in emergency situations while waiting for first responders with more advanced equipment and training to arrive. Always call 911 before locating and using either type of device.

The devices are placed in occupied buildings owned or leased by the City of Chicago, as part of the Safe Chicago project led by the Office of Emergency Management & Communications.

For more information on the Safe Chicago program, please see https://www.chicago.gov/city/en/depts/oem/supp_info/safe-chicago.html.

All trips, starting November 2018, reported by Transportation Network Providers (sometimes called rideshare companies) to the City of Chicago as part of routine reporting required by ordinance.

Census Tracts are suppressed in some cases, and times are rounded to the nearest 15 minutes. Fares are rounded to the nearest $2.50 and tips are rounded to the nearest $1.00.

Corrections are possible during the course of the sweeping season.

Records are added to the Building Code Scofflaw List every six months and these records are the ones in effect until the next update. Older records are kept in the dataset for historical reference. This filtered view shows just the current records -- those with the most recent BUILDING LIST DATE.

Please see the description section for the full dataset for further information about the data.

The Chicago Building Energy Use 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 was phased 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

The ordinance authorizes the City to share property-specific information with the public, beginning with the second year in which a building is required to comply.

The dataset represents self-reported and publicly-available property information by calendar year. Currently, the data includes calendar year 2014 information for 243 properties, calendar year 2015 information for over 1,500 properties, calendar year 2016 information for over 2,700 properties, and calendar year 2017 information for almost 2,800 properties.

The "Data Year" column and filtered views under "More Views" can be used to isolate specific years.

The Chicago Public Library offers one-hour computer sessions and 15-minute computer sessions.

Many locations experience sporadic closures to perform facilities upgrade or emergency closures due to heating or air conditioning issues, or area power outages.

Bike racks in Chicago.

This dataset contains bike racks installed between 2015-2021. There is another dataset from 2011 at https://data.cityofchicago.org/d/cbyb-69xx that shows bike racks in existence at that time. We hope eventually to consolidate the data into this dataset.

Taxi trips reported to the City of Chicago in its role as a regulatory agency. To protect privacy but allow for aggregate analyses, the Taxi ID is consistent for any given taxi medallion number but does not show the number, Census Tracts are suppressed in some cases, and times are rounded to the nearest 15 minutes.

Due to the data reporting process, not all trips are reported but the City believes that most are.
