4151 S Berkeley Ave
A handful of records on file over the last seven years, and our model predicts a high risk of further maintenance problems in the next 12 months. A few records worth reading before you sign. Check whether they were closed out, and ask what was actually fixed.
This building has 5 building violations (7y), above the Oakland average of 4.2.
The three-story, six-unit residential building at 4151 S Berkeley Ave in the Oakland neighborhood, owned by Denis Dankin, has experienced a notably challenging recent history. Most concerning are the five unresolved building violations documented in April 2023, which were initiated through complaint-driven inspections and remain open. The property has also generated an unusually high volume of 311 service requests, with 161 total requests filed under the owner's name over the past seven years, including multiple sanitation code violations and rodent-related complaints. While the building was constructed in 1901 and has had some permits filed (three in total for the owner), the most recent records from 2026 show continued maintenance and sanitation issues, including three recent sanitation code violations and one rodent complaint that were officially closed, along with an open building violation request from July 2026.

Unlock complete reportHow 4151 S Berkeley 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 132 buildings in this neighborhood, 108 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
