Unlock complete reportThe three-unit residential building at 845 N Leavitt St in the Ukrainian Village, owned by Ken Kosinski, is a 1910 structure that has experienced several notable incidents over the past seven years. The property has had a total of 24 service requests, with four specifically related to the building itself and the others presumably concerning street-level or neighborhood issues, including three recent water-related complaints and one pothole complaint in 2026. The building's recent water issues are particularly noteworthy, with two water complaints in March 2026 and an open water lead test kit request from December 2025. The property has also experienced some regulatory challenges, with records showing two house share violations and one environmental complaint, though building permits taken out by the owner appear minimal at just three in this period. While the building has stood for over a century, its most pressing current concerns appear to be centered around water-related issues, based on the recent complaint patterns and the open lead test kit request.

How 845 N Leavitt St 1's risk score is calculated
We trained a model on 7 years of Chicago code enforcement data — building violations, 311 complaint history, environmental enforcement, and owner track records. It estimates the probability that the City of Chicago will find a code violation at this address in the next 12 months. Lower % = safer.
What the score means for you
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
