Unlock complete reportThe two-unit residential property at 3620 S California Ave in Brighton Park, built in 1919 and currently owned by Mario Sandra Lopez, has experienced a concerning number of maintenance and public health issues in recent years. Most notably, the building has seven unresolved complaint-driven inspection violations recorded as of October 3, 2025, marking a significant and ongoing compliance concern. The property has also generated multiple 311 service requests in 2026, including three dead animal pick-up requests in March, a rodent baiting complaint in March, a graffiti removal request in March, and a garbage cart maintenance issue in January. These recent service requests indicate potential challenges with building maintenance and surrounding environmental conditions. Looking further back, there was an air pollution work order complaint filed in August 2001, though this appears to be an isolated incident in comparison to the recent pattern of issues.

How 3620 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, 3447 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
