Unlock complete reportThe two-unit residential building located at 6534 S Karlov Ave in Chicago's West Lawn neighborhood has been owned by Socorro Perez since its construction in 1952. Over the past seven years, the property has generated 15 service requests through the city's 311 system, with the most recent cluster of incidents occurring in early January 2026, including a basement water issue and two reports of abandoned vehicles on the same day. The building experienced a concerning pattern of issues in October 2025, with three separate service requests made within a single day, including two dead animal pick-up requests and one information-only call. While the total number of 311 calls is relatively moderate in comparison to some properties, the concentration of multiple incidents in specific months and the nature of certain complaints, such as the basement water issue, may warrant attention. All reported issues appear to have been resolved according to the closed status of the service requests.
How 6534 S Karlov 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
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.
Out of 692 buildings in this neighborhood, 152 are predicted to be safer.
