Unlock complete reportThe two-unit residential building at 3142 N Kolmar Ave in Chicago's Hermosa neighborhood, constructed in 1927 and currently owned by Cesar Najera, has a relatively limited history of documented service requests over the past seven years. The property has recorded a total of five 311 service requests, with the most recent cluster of incidents occurring in early 2026, when multiple reports were filed regarding injured animals and a dead bird within close succession in February of that year. Prior to these animal-related incidents, there was a fly dumping complaint filed in May 2024. The only other documented interaction with city services in this period was an information-only call in April 2026. Given the nature of these incidents, while they indicate some environmental and neighborhood maintenance issues in the immediate vicinity, none of the recorded service requests directly relate to building safety or tenant living conditions. The relatively low number of service requests over this seven-year period, especially considering the building's age, is somewhat notable, though it's important to remember that not all building issues necessarily generate official service requests.

How 3142 N Kolmar 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.
Out of 1618 buildings in this neighborhood, 178 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
