Initial analysis

The three-unit residential building at 7827 S Winchester Ave in the Auburn Gresham neighborhood, owned by Yolanda J. Irby Alexa, has been in existence since 1927 and has experienced several significant events throughout its history. Most pressing are the seven unresolved building code violations recorded on March 24, 2026, which were initiated through complaint-driven inspections and represent the building's most recent and perhaps most concerning issues. Additionally, during the first half of 2026, there was a recorded vicious animal complaint in February 2025, though this matter was subsequently closed. The building's earlier history includes two asbestos-related work order complaints from 2001, specifically filed in January and June of that year, which were likely addressed at the time given their age. The overall record of building violations and service requests over the past seven years shows a total of seven violations and two service requests, with the majority of recent activity focused on the 2026 unresolved violations.

Risk rating

How 7827 S Winchester Ave 1St'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.
