Initial analysis

The two-unit residential building at 3121 W 40th Street in Brighton Park, owned by Alfredo Garcia, was constructed in 1924 and has experienced a notable increase in building code violations in 2024, with six unresolved complaint-driven inspection violations recorded on March 19, 2024. This recent cluster of violations marks a significant departure from the building's historical record, which shows only a total of six building violations across all categories in the past seven years. The property has generated three 311 service requests over the past seven years, with two of these relating to vehicles (an abandoned vehicle complaint in February 2025 and a finance parking code enforcement review in June 2026), and one concerning an injured animal in November 2025, all of which have been closed. It's worth noting that the owner, Alfredo Garcia, appears to have multiple properties under their name, with records showing four total parcels, though the specific details of these other properties are not included in this report.

Risk rating

How 3121 W 40Th St'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.
