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.

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, continued inspections until the building receives two consecutive inspections, at least six months apart, during which no serious violations are found. Individuals identified 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.
