Unlock complete reportThe two-unit, 1926 building at 3046 N Kostner Ave in the Hermosa neighborhood, owned by Sanjuana Vargas, has maintained a relatively stable record over recent years, with the most significant cluster of issues occurring in 2026. The property has experienced two building code violations in the past seven years, both from November 2019, which were promptly resolved. The most recent service requests cover a range of maintenance and environmental concerns, including a rodent baiting complaint, tree removal inspection, garbage cart maintenance, and two alley pothole complaints, all recorded in early to mid-2026. The tree removal request remains open as of October 2023. An environmental complaint regarding illegal dumping was filed in 1998, though this appears to be an isolated incident from the distant past. While the building has encountered occasional maintenance issues, most violations and service requests have been addressed promptly, with the exception of the currently open tree removal request.

How 3046 N Kostner 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, 1505 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
