10921 S Western Chicago
Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.
This building has 0 building violations (7y), at or below the Morgan Park average of 2.1.
The bar and the rating point different ways because they measure different things: the bar counts building violations already on file, the rating forecasts the next 12 months.

Unlock complete reportThe 20-unit residential building at 10921 S Western in Chicago's Morgan Park neighborhood, owned by William J Bonner, has experienced a notable cluster of issues in 2026. The property, constructed in 1954, has had multiple open violations in recent months, including two concerning unauthorized construction work in April 2026, which remain unresolved as of the latest data. Earlier in the year, there were two additional building violations in January and February that have since been closed. The building's recent service history shows a significant increase in activity compared to previous years, with most 311 service requests in 2026 relating to building violations rather than maintenance issues. Between 2016 and 2023, there were only 13 service requests on file for the entire seven-year period, suggesting a sudden escalation of concerns in the current year. Other service requests this year include a tree trimming request from March and a closed complaint regarding a pushcart food vendor from June. While the building has only one permit on record for the past seven years, the nature of the currently open building permit violations suggests ongoing concerns about unauthorized modifications or construction activity.

How 10921 S Western Chicago's risk score is calculated

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
