Unlock complete reportThe five-unit residential building at 840 W Grand Ave in Chicago's West Town neighborhood is a century-old property owned by Jay B Ross, which has exhibited several concerning trends in its recent history. Most notably, the building has one unresolved building code violation from July 2022 related to a periodic routine inspection, suggesting potential ongoing regulatory compliance issues. The property has also experienced recurring sanitation challenges, with two sanitation code violation reports in early 2026, though these were subsequently closed. Recent months have seen a cluster of graffiti incidents, with two removal requests filed in February 2026. Additionally, there is an open complaint regarding shared housing or vacation rental activity from May 2026, which could indicate unauthorized short-term rental operations. The building's documented history includes minimal construction activity, with only one building permit on record in the past seven years, and while there have been 16 service requests filed through the city’s 311 system, most of these have been resolved through proper channels, with only the most recent requests remaining open. The combination of unresolved violations, frequent sanitation issues, and concerns about unauthorized rental activity suggests a pattern of maintenance and regulatory challenges at this property, though many past issues have been addressed through the appropriate city services.

How 840 W Grand 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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 2255 buildings in this neighborhood, 2030 are predicted to be safer.
