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 "Related Content" can be used to isolate specific years.

As described in https://data.cityofchicago.org/stories/s/311-Dataset-Changes-12-11-2018/d7nq-5g7t, the function of this dataset was replaced by https://data.cityofchicago.org/d/v6vf-nfxy. This dataset is historical-only.

This dataset contains all open 311 reports of one or more lights out on a wooden pole in the alley and all completed requests since January 1, 2011. If two requests regarding the same address are made within 30 calendar days of each other, the newest CSR is automatically given the status of “Duplicate (Open)”. Once the alley light is repaired, the CSR status will read “Completed” for the original request and “Duplicate (Closed)” for any duplicate requests. Data is updated daily.

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.

This dataset shows approximate, average, weekday boardings by bus stop from the month of October 2012.

All restaurants and food stores selling perishable items are required to apply for a Retail Food License (RFL). This metric tracks the average number of days the Department of Business Affairs and Consumer Protection (BACP) takes to issue RFLs. The target response time for processing is within 15 days.

Records involving any degree of street closure from the underlying dataset: Applications to the Chicago Department of Transportation for permits under its jurisdiction, which typically are permits to block or otherwise affect public streets in some way. Because all permits start as applications, this dataset also serves as a list of permits granted. See more information about CDOT permits at http://www.cityofchicago.org/city/en/depts/cdot/provdrs/construction_information/svcs/online-permit-portal.html.

This dataset contains the historical estimated congestion for 1270 traffic segments, in selected time periods from August 2011 to May 2018. Newer records are in https://data.cityofchicago.org/d/sxs8-h27x. The most recent estimates for each segment are in https://data.cityofchicago.org/d/n4j6-wkkf.

The Chicago Traffic Tracker estimates traffic congestion on Chicago’s arterial streets (non-freeway streets) in real-time by continuously monitoring and analyzing GPS traces received from Chicago Transit Authority (CTA) buses. Two types of congestion estimates are produced every 10 minutes: 1) by Traffic Segments and 2) by Traffic Regions or Zones. Congestion estimates by traffic segments gives observed speed typically for one-half mile of a street in one direction of traffic. Traffic Segment level congestion is available for about 300 miles of principal arterials. Congestion by Traffic Region gives the average traffic condition for all arterial street segments within a region. A traffic region is comprised of two or three community areas with comparable traffic patterns. 29 regions are created to cover the entire city (except O’Hare airport area). There is much volatility in traffic segment speed. However, the congestion estimates for the traffic regions remain consistent for a relatively longer period. Most volatility in arterial speed comes from the very nature of the arterials themselves. Due to a myriad of factors, including but not limited to frequent intersections, traffic signals, transit movements, availability of alternative routes, crashes, short length of the segments, etc. Speed on individual arterial segments can fluctuate from heavily congested to no congestion and back in a few minutes. The segment speed and traffic region congestion estimates together may give a better understanding of the actual traffic conditions. Current estimates of traffic congestion by region are available at http://bit.ly/Vz3rIh.

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.

Permits issued by the Department of Environment (DOE) from January 1993 to December 31, 2011 and by the Department of Public Health (CDPH) since January 1, 2012. This dataset also includes tank permits issued by CDPH on behalf of the Office of the Illinois State Fire Marshall (OSFM).

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.

Population totals for groupings commonly used in other datasets.

Not all values are available for all years.

Note that because the "Citywide" rows roll up the values from the individual ZIP Codes and the "Age 0-4," "Age 5-11," "Age 12-17," "Age 5+," "Age 18+," and "Age 65+" columns overlap other age categories, as well as each other in some cases, care should be taken in summing values to avoid accidental double-counting. The "Age 5-11" and "Age 12-17" columns only include children who live in households.

Data Sources: U.S. Census Bureau American Community Survey (ACS) 5-year estimates (ZIP Code) and 1-year estimates (Citywide). The U.S. Census Bureau did not release standard 1-year estimates from the 2020 ACS. In 2020 only, 5-year estimates were used for the Citywide estimates.

Data set contains all 311 calls for open and vacant buildings reported to the City of Chicago since January 1, 2010. The information is updated daily with the previous day's calls added to the records. The data set provides the date of the 311 service request and the unique Service Request # attached to each request. For each request, the following information (as reported by the 311 caller) is available: address location of building; whether building is vacant or occupied; whether the building is open or boarded; entry point if building is open; whether non-residents are occupying or using the building, if the building appears dangerous or hazardous and if the building is vacant due to a fire.

The Chicago Park District issues swim advisories at beaches along Chicago's Lake Michigan lakefront based on E. coli levels. This map shows predicted E. coli levels -- with bubble size corresponding to predicted level -- and whether the predicted E. coli level was at least 235 Colony Forming Units (CFU) per 100 ml of water (red bubbles).

This map updates daily and its predictions depend on data from https://data.cityofchicago.org/Parks-Recreation/Beach-Lab-Data/2ivx-z93u. It will show no predictions from midnight until the new day's predictions have been generated.
