Unlock complete reportThe two-unit residential building at 3206 S Karlov Ave in Little Village, owned by Lorena Rojas Vargas, has experienced several maintenance issues over the past year and beyond. Most notably, from March 2025, there has been a concerning pattern of water-related problems, with multiple complaints about water in the basement and checks for leaks taking place between March 7 and March 28 of that year. The building also required sewer cleaning inspection services during this same period, suggesting ongoing moisture and drainage challenges. Looking further back in the building's history, there was an air pollution complaint in 2014 that was officially resolved by October of that year. Given the recent concentration of water-related issues, particularly in March 2025, this building's infrastructure appears to be experiencing significant plumbing and moisture management difficulties that could impact resident comfort and safety.
How 3206 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 5739 buildings in this neighborhood, 2468 are predicted to be safer.
