Unlock complete reportThe property at 740 W Cornelia Ave in Chicago's Boystown neighborhood is a 6-unit residential building constructed in 1914, currently owned by Mid North Construction. Over the past seven years, the building has experienced several notable issues, with the most significant being a concerning pattern of rodent-related complaints in 2025-2026, including four distinct reports of rat problems between December 2025 and April 2026. The building has also faced infrastructure maintenance challenges, evidenced by complaints about snow-uncleared sidewalks in December 2025 and a street pothole in April 2025. While the building has been the subject of 39 service requests during this period, only two building violations are on record, and there has been minimal construction activity with just one building permit issued. The relatively small number of 311 service requests for the past seven years, totaling 10, could suggest either limited reporting or possibly fewer urgent issues requiring city intervention.

How 740 W Cornelia Ave'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
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 121 buildings in this neighborhood, 56 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
