Unlock complete reportThe two-unit residential building at 6412 S Komensky Ave in the West Lawn neighborhood, owned by Andres Sosa, has been in operation since 1926 and has experienced several notable maintenance-related events over the past several years. The property has generated a total of five service requests through the 311 system between 2024 and 2025, with the most significant concerns involving water-related issues, including a basement water complaint and sewer-related matters. Both the basement water complaint and sewer cleaning inspection requests were filed in July 2025, which may indicate ongoing water management challenges at the property, while a sewer inspection request related to the alley was made in July 2024, suggesting potential concerns with the building's waste management infrastructure. The property has also required attention to other maintenance matters during this period, including tree trimming (November 2025), garbage cart maintenance (August 2024), and the aforementioned sewer-related inspections. Despite these service requests, there has been only one building permit filed in the past seven years, which is worth noting in the context of regular maintenance and improvements.
How 6412 S Komensky 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, 270 are predicted to be safer.
