AI summary

The two-unit residential property at 4726 W Montana St in Belmont Cragin, owned by Carlos G Leon, is a 1923 building that has had a relatively low number of service requests over the past seven years. The most recent notable incident in June 2026 involved multiple tree-related emergencies, with three immediate responses required from different departments, including the Alderman's office and Streets and Sanitation. While one of these tree-related requests has been marked as open, suggesting ongoing issues, the others were successfully resolved. Earlier in the year, in February 2026, there was a documented case of fly dumping near the property that was addressed and closed. The building's overall service request history is limited, with a total of eight requests filed by both residents and the property owner, though it's worth noting that the current records appear to contain several unusual date anomalies, showing multiple requests in June 2026, including one that seems to be in the future, which may warrant verification of the data's accuracy.

Risk rating

How 4726 W Montana St 1Fl'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.
