Unlock complete reportThe 15-unit apartment building at 4156 N Mozart Street in Chicago's Irving Park neighborhood is a 1925 structure currently facing multiple unresolved building code violations from a series of complaint-driven inspections, with records showing at least six open violations from December 2019 through March 2020. The property has generated a total of ten building violations over the past seven years, with the owner, identified as "TAXPAYER OF," also associated with a significantly larger number of city-wide violations totaling 2,228 across all parcels, including various housing-related infractions and 3 house share violations. While the building's 311 service requests for the past seven years show relatively few building-specific issues (only six requests directly related to the building itself), there have been numerous requests related to the surrounding area, including three pothole complaints and two abandoned vehicle reports in 2025, as well as a leak check request to the Department of Water Management that was documented as closed.

How 4156 N Mozart Chicago'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
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby

Out of 3731 buildings in this neighborhood, 3731 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
