Unlock complete reportThe two-story building at 4904 S Komensky Ave in Chicago's Archer Heights neighborhood was constructed in 1929 and is currently owned by Fermin Hernandez. The property, which comprises three parcels under its current ownership, has a relatively low record of 311 service requests and building permits over the past seven years, with only a single building permit filed during this period. However, a concerning pattern of water-related issues has emerged in and around the property, particularly during August 2025, when three separate incidents involving water problems were reported within a short timeframe, including two complaints about basement water accumulation and a request to check for leaks. More recently, in early 2026, there have been additional concerns about water safety, with an open request for a water lead test kit, following the closure of a graffiti removal request. The building's service request history shows minimal recorded issues in prior years, indicating that most recent complaints have emerged within a concentrated period between 2025-2026, with water-related problems appearing to be the most significant recurring concern for residents.

How 4904 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
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
