Unlock complete reportThe property at 4207 South California Avenue in Brighton Park is a two-unit residential building constructed in 1923, currently owned by Phillip J Olazaba. The building's documented service history over the past seven years shows a total of four 311 service requests, with the most recent being an open request for a blue recycling cart made on May 31, 2026. Notably, there were two rodent-related complaints filed in 2024 (April and September) that have since been closed, along with a water lead test kit request in April 2024 that has also been resolved. The frequency of these service requests, particularly the rodent issues, suggests some ongoing maintenance challenges, though the property's most recent communication with city services regarding a recycling cart could indicate an ongoing dialogue with municipal services.
How 4207 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
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 3956 buildings in this neighborhood, 1701 are predicted to be safer.
