Initial analysis

The property at 8538 W Catalpa Avenue in O'Hare is a 5-unit residential building constructed in 1970 and currently owned by K J Johnson Properties. Over the past seven years, the building's record shows minimal activity, with only two building violations and three 311 service requests. The most recent service request, from February 2026, was regarding a tree trimming need, though it's worth noting that this type of request is no longer being accepted through the 311 system. Prior to that, in July 2024, there was a successful request for graffiti removal from the property. Given the relatively low number of service requests and violations on record, the building's maintenance and management history appears to be generally stable, though the records do not provide insight into the property's current condition or any ongoing maintenance practices.

Risk rating

How 8538 W Catalpa Ave 1'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.
