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.

Violations issued by the Department of Buildings in the City of Chicago from 2006 to the present. The dataset contains more than 1 million records/rows of data and cannot be viewed in full in Microsoft Excel. Therefore, when downloading the file, select CSV from the Export menu. Open the file in an ASCII text editor, such as Wordpad, to view and search. Violations are always associated to an inspection and there can be multiple violation records to one(1) inspection record. Data fields requiring description are detailed below. VIOLATION DATE: The date the violation was cited. INSPECTION CATEGORY: Inspections are categorized by one of the following: COMPLAINT – Inspection is a result of a 311 Complaint PERIODIC – Inspection is a result of recurring inspection (typically on an annual cycle) PERMIT – Inspection is a result of a Permit REGISTRATION – Inspection is a result of a Registration (typically Vacant Building Registration) PROPERTY GROUP: Properties (lots) in the City of Chicago can typically have multiple point addresses, range addresses and buildings. Examples are corner lots, large lots, lots with front and rear buildings, etc.. As a result, inspections (and their associated violations), permits and complaints related to a single property could have different addresses. This problem can be reconciled by using Property Group. All point and range addresses for a property are assigned the same Property Group key.

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

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. For more information on the City’s life safety ordinance, visit http://bit.ly/ygORcq. Data Owner: Buildings. Frequency: Data is updated monthly.
