Unlock complete reportThe property at 1940 N Kostner Ave 1 in the Hermosa neighborhood is a two-unit building constructed in 1898 and currently owned by Maximino Arciniega. The building's documented history over the past seven years shows a total of 29 service requests filed through the 311 system, with the most recent activity occurring in 2026. The most significant recent developments involve tree-related issues, with two service requests made on April 14, 2026, including a tree emergency (now closed) and an open request for tree removal inspection. The property has experienced recurring issues with road maintenance, particularly potholes, as evidenced by four separate pothole complaints between January and February 2026, all of which have been resolved. While the building's age and history are noteworthy, it's important to note that the majority of recent service requests have been related to street and tree conditions rather than building-specific issues, with no documented complaints regarding the building's structure or residential systems during this period.

How 1940 N Kostner Ave 1'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, 825 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
