Initial analysis

The three-parcel, 19-unit residential building at 7920 S Evans in the Chatham neighborhood, operated by Osmium Builders LLC, was constructed in 1924 and has encountered several concerning issues in recent years. Most significantly, there are currently four open building code violations as of October 2024, all stemming from recent complaint-driven inspections. The property has also experienced recurring health and safety concerns, with documented issues including rodent problems (as of December 2024), water lead testing (August 2024), and lead inspection requirements (July 2024), though some of these matters have been previously addressed and closed. The building's maintenance history includes a notable pattern of service requests to city agencies, with 41 total requests made by the owner in the past seven years, including a recent ice and snow removal request (January 2026). While there have been some building permits documented, only one permit was issued in the past seven years, suggesting limited major renovation activity. The combination of open building code violations and repeated health-related inspections indicates ongoing maintenance challenges that have persisted into late 2024.

Risk rating

How 7920 S Evans Chicago'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.
