Unlock complete reportThe six-unit residential building at 1920 S Blue Island in Chicago's Lower West Side, owned by Dennis J Topolski, has a mixed record of maintenance and compliance since its construction in 1881. Most notably, there is currently an open unresolved issue related to the periodic routine inspection conducted in March 2024, one of four such inspections from that date, while two other inspections from the same date were successfully resolved. The building has experienced 11 violations over the past seven years, with the most recent inspection-related issues suggesting potential ongoing concerns with building maintenance or safety protocols. Additionally, there have been 19 service requests through 311 over the same period, including recent complaints about water in the basement and plumbing violations in 2026, and multiple tree trim requests and graffiti removal incidents in 2025, all of which were ultimately resolved. Historical records show environmental concerns from 2009 regarding toxic hazardous materials and an illegal dumping incident in 1999, though these are older issues and not necessarily indicative of current conditions. The building's records reflect regular municipal interactions, with the majority of issues being addressed and resolved through appropriate channels, though the recent open violations warrant attention.

How 1920 S Blue Island'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 3683 buildings in this neighborhood, 3683 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
