AI summary

The three-unit residential building at 3687 W Grand Ave, located in Chicago's Humboldt Park neighborhood, is a 1913 construction currently owned by Castillos Auto Repair. The property has a relatively minor record of city service interactions over the past seven years, with a total of five documented 311 service requests. These requests, all of which have been resolved, show a cluster of activity in early 2026, including two graffiti removal requests, an abandoned vehicle complaint, and a report of an injured animal, all of which were closed. Prior to this cluster of incidents, there was one service request in September 2024 regarding garbage cart maintenance. While the building's external environment appears to have faced some challenges with graffiti and abandoned vehicles, particularly in early 2026, there are no recorded service requests directly related to the building's internal conditions or systems, and all reported issues have been appropriately addressed through the city's 311 system.

Risk rating

How 3687 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.
