Initial analysis

The two-unit residential building at 7835 S Aberdeen St in Chicago's Auburn Gresham neighborhood, managed by owner Kelwin Harris, was constructed in 1918 and has experienced several significant maintenance and safety issues in recent months. Most notably, the property has generated multiple vacant/abandoned building complaints and rodent-related concerns between July and September 2025, with a particular cluster of these incidents occurring in July 2025 when three separate vacant building complaints were filed within a single day. The frequency and recent nature of these complaints, with a total of six vacant building complaints and three rodent-related issues in just over two months, suggest persistent property maintenance challenges and potential safety concerns for residents. While all service requests have been marked as closed, the pattern of complaints indicating potential vacancy and pest problems is particularly concerning given the relatively small time frame during which they occurred.

Risk rating

How 7835 S Aberdeen St 01'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.
