Unlock complete reportThe two-unit residential building at 4502 S California Ave 1 in Brighton Park, owned by J Martinez, is a vintage structure built in 1924. The property's documented service history over the past seven years shows minimal activity, with only two service requests recorded through the 311 system during this period. The most recent request, logged in February 2026, concerned a tree trimming matter, though it's worth noting that such requests are no longer being accepted through the 311 system. Prior to this, there was a leak investigation request made in July 2024, which has since been resolved. The building's overall service request record appears relatively clean, with only these two incidents requiring municipal attention over the past several years, suggesting stable property maintenance during this period. The owner holds records for two parcels in total, with a slightly higher service request count of seven when considering all their properties over the same seven-year period, though specific details of these additional requests are not provided in the available data.
How 4502 S California Ave 1'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, 2255 are predicted to be safer.
