Initial analysis

The three-unit residential building at 4140 N Western Ave in Chicago's North Center neighborhood, owned by James B Walton and constructed in 1899, has experienced significant ongoing issues in recent years. Most notably, there are currently six open and unresolved building code violations as of February 2025, all arising from complaint-driven inspections. These violations are part of a concerning pattern, with the property accumulating a total of 55 building violations over the past seven years. The building has also generated high levels of service requests through the 311 system, with 62 reports recorded in the same time frame. While most recent 311 service requests from late 2025 and early 2026 have been relatively mundane (including abandoned vehicle complaints, a water lead test kit request, yard waste pickup, and graffiti removal), the volume of both building violations and service requests suggests ongoing maintenance and safety challenges. An earlier environmental complaint regarding air pollution was recorded in February 2006, though this predates the current ownership period significantly.

Risk rating

How 4140 N Western 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.
