Initial analysis

The two-unit, 1888 residential building at 6417 S Aberdeen St in Chicago's Englewood neighborhood, currently owned by Boss Theardis, has experienced several concerning incidents over the past seven years. Most notably, between August 2025 and May 2026, there were multiple complaints regarding the property and its surroundings, including three vacant/abandoned building complaints (one to DOB - Buildings and two to the Alderman's office), a sanitation code violation, and two related to animal issues (a stray animal complaint and a vicious animal complaint) in the immediate vicinity. The property's condition and safety concerns appear to have peaked in late 2025 and early 2026, with the vacant/abandoned building status generating multiple reports, though all these complaints have been marked as closed. The building's 311 service request history shows a total of 12 documented interactions with city services over the past seven years, though it's worth noting that this is a relatively small number of reported issues for a building of its age and size.

Risk rating

How 6417 S Aberdeen St 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.
