INFORMATION ABOUT 7/12/2019 CHANGES TO THIS DATASET: http://bit.ly/2XV3ERS -- This dataset includes information about currently-valid building permits issued by the City of Chicago from 2006 to the present. Building permits are issued subject to payment of applicable fees. If building or zoning permit fees show as unpaid, the permit is not valid. (A permit is valid if only “other fees” are shown as unpaid.) This dataset does not include permits which have been issued and voided or revoked. This dataset also does not include permits for mechanical amusement riding devices and carnivals issued by the Department of Buildings.

Property Index Numbers (PINs) and geographic information (ward, community area and census tract) are provided for most permit types issued in 2008 or later.

For more information on building permits, see https://www.chicago.gov/city/en/depts/bldgs/provdrs/permits.html.

For an application related to building permits and inspections, see https://webapps1.chicago.gov/buildingrecords.

This list describes landlords and property owners who are designated "problem landlords". Landlords on this list have had two or more administrative hearing causes brought against them and were found liable or defaulted to one or more serious building violations.

Violations issued by the Department of Buildings from 2006 to the present. Lenders and title companies, please note: 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 to an inspection and there can be multiple violation records to one inspection record.

The information presented on this website is informational only and does not necessarily reflect the current condition of the building or property. 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.

The Chicago Building Scofflaw Ordinance (Section 2-92-416 of the Municipal Code of Chicago) is designed to prevent landlords that refuse or refrain from correcting ongoing building code violations from receiving city contracts, including those that subsidize housing. Building owners must have a least three residential buildings with uncorrected violations and have had three or more properties referred to Circuit Court within the applicable 12 month period to be eligible for the list. The building code scofflaw list is updated once a year on the first business day of December, and building owners may appeal being named on the list. Building owners with controlling interest in at least three residential properties that have habitual, extensive or serioues building code violations are now ineligible for any new city contracts in 2015. The following individuals or entities have been placed on the Building Code Scofflaw list for the entire calendar year.

The following dataset includes "Active Benchmarks," which are provided to facilitate the identification of City-managed standard benchmarks. Standard benchmarks are for public and private use in establishing a point in space. Note: The benchmarks are referenced to the Chicago City Datum = 0.00, (CCD = 579.88 feet above mean tide New York). The City of Chicago Department of Water Management’s (DWM) Topographic Benchmark is the source of the benchmark information contained in this online database. The information contained in the index card system was compiled by scanning the original cards, then transcribing some of this information to prepare a table and map. Over time, the DWM will contract services to field verify the data and update the index card system and this online database.This dataset was last updated September 2011. Coordinates are estimated.

Vacant and abandoned building violations issued on properties owned by financial institutions since January 1, 2011. Each violation is tied to a Docket Number. A Docket may have more than one violation associated with it. Fees are assessed based on all violations associated with a particular Docket. This dataset displays the most recent action (disposition description) for each violation, the fees and fines associated with the docket and the amount paid or outstanding for the docket. If the docket is a City Non-Suit or the owner is found to be Not Liable, then no payment is required. Note that multiple addresses may be associated with a violation; in these cases, multiple records will be included in this dataset for a single violation. / Data Owners: Administrative Hearings / Finance / Time Period: January 1, 2011 to present / Update Frequency: Data is updated daily

OUTDATED. This dataset will not be updated further due to changes in how the source data are maintained. For more information on the City’s life safety ordinance, see https://www.cityofchicago.org/city/en/depts/bldgs/provdrs/inspect/svcs/life_safety_high-riseordinance.html and the contact information on that page. -- This dataset is a listing of the report status of all residential buildings required to submit a Life Safety Evaluation under city ordinance. Because the Chicago building code has since 1975 required new high-rise residential buildings to be constructed with sprinkler systems, the Life Safety Ordinance mostly impacted high-rise residential buildings constructed prior to 1975. This dataset does not describe the overall safety of a building, only whether or not the life safety evaluation was submitted and approved by the City of Chicago. Please note that the majority of reports “failed” initially as a result of a new reporting process and changes to building standards.

This list describes landlords and property owners who are designated "problem landlords". Landlords on this list have had two or more administrative hearing causes brought against them and were found liable or defaulted to one or more serious building violations.

The Chicago City Code, Chapter 4-17, allows for shared housing rentals to be prohibited or restricted in specified precincts. This dataset shows those precincts for which such restrictions have been requested by voter petition, including those approved by ordinance and potentially those for which an attempted repeal of the prohibition is underway or complete.

Current status can be determined from the most recent date.

This filtered view contains applications for preapprovals for Additional Dwelling Units (ADUs) that have been successfully processed and have an "Issued" status.
