Unlock complete reportThe two-unit residential building at 1849 N Kostner Ave in Hermosa, built in 1898 and currently owned by Lorena Lazcano, has experienced several notable issues over recent years. The property has generated 23 service requests through the 311 system over the past seven years, with the most recent cluster of complaints occurring throughout 2026, including incidents related to no water issues, garbage cart maintenance, street potholes, and public way inspections. Of particular concern is an unresolved building code violation from November 2021, along with five building code violations from September 2022 that were subsequently resolved. While these complaint-driven inspections were addressed, the single open violation suggests potential ongoing concerns. Looking further back, there was an environmental complaint regarding illegal dumping logged in March 1996, though this appears to be an isolated incident from many years ago. The building's violation and service request history shows a pattern of maintenance and service issues that have required attention, particularly in recent years, with the majority of noted problems occurring within the last two years.

How 1849 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
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 1617 buildings in this neighborhood, 1568 are predicted to be safer.
