Initial analysis

The two-unit residential building at 4312 S Sawyer Ave in Chicago's Brighton Park neighborhood, constructed in 1925 and currently owned by Gregorio I Gardun, has had a relatively uneventful recent history according to the available records. The property, with only three documented 311 service requests in the past seven years, has experienced a cluster of graffiti-related issues in February 2026, with three separate requests for graffiti removal registered between February 9 and February 10 of that year, all of which have since been closed. These recent incidents stand out as the only recorded service requests during the seven-year period, suggesting that prior to 2026, and since, there have been no significant maintenance or public safety concerns reported through the 311 system.

Risk rating

How 4312 S Sawyer 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.
