Initial analysis

The three-unit residential building at 7838 S Winchester Ave in the Auburn Gresham neighborhood, owned by Quincy Percy, has experienced several significant events in recent months that warrant attention. Most notably, on June 11, 2024, the property received multiple complaint-driven inspections, with six open violations recorded on that same date, though the specific nature of these violations is not detailed in the records. Prior to these recent developments, there was one 311 service request made in June 2024 regarding a water lead test, which has since been closed. Looking at the broader history of the property over the past seven years, there have been a total of seven building code violations and one other 311 service request, suggesting that while the property has had some regulatory scrutiny, the most recent cluster of violations is by far the most substantial in recent history. The building dates back to 1929, and while its ownership structure shows only one total parcel under Quincy Percy, the records indicate multiple open issues that appear to require follow-up attention.

Risk rating

How 7838 S Winchester Ave'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

Lower risk — safer than most nearby

City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.

Typical — about average for the neighborhood

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Higher risk — riskier than most nearby

Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
