Unlock complete reportThe two-unit residential building at 4345 S California Ave in Brighton Park, owned by Diamian Uribe Nava, is a 1916 structure that has encountered several regulatory challenges over the past seven years. Most notably, in October 2022, the building underwent a series of complaint-driven inspections that resulted in six resolved code violations. While the exact nature of these violations is not specified, it's worth noting that a cluster of violations resolved in quick succession generally indicates prompt attention to regulatory compliance. The property has maintained regular occupancy since its construction, having only two recorded 311 service requests in the past seven years: a street light outage complaint in July 2025 and a graffiti removal request in April 2025, both of which were closed. While the recent graffiti and lighting issues suggest some external maintenance concerns in the immediate vicinity, these matters were addressed through normal city service channels. The concentration of violations in a single month in late 2022, while concerning, is somewhat mitigated by their prompt resolution.

How 4345 S California 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 3962 buildings in this neighborhood, 3922 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
