Unlock complete reportThe seven-unit, 1928 building at 3101 N Natoma in Chicago's Montclare neighborhood, currently owned by Lukasz Bratko, has experienced a limited number of significant issues over the past seven years. The property has two resolved building code violations from November 2019, both stemming from complaint-driven inspections. In terms of maintenance and service requests, there have been seven 311 calls in recent years, with the most recent being a dead bird report in May 2026. The building's service requests have primarily centered around external maintenance issues, including two tree trimming requests (closed) in late 2025 and a pothole complaint (currently open) from April 2026. Earlier complaints also included a check for a leak in August 2025 and another dead bird report from the same month, both of which were resolved. Notably, there has been only one building permit recorded in the past seven years, though this alone does not imply any particular concern about property maintenance or safety.

How 3101 N Natoma Chicago'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 459 buildings in this neighborhood, 454 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
