Unlock complete reportThe two-unit residential building at 3519 S Union Ave in Chicago's Bridgeport neighborhood is an 1888 structure currently owned by Francisco Ruiz. The property has a relatively low number of service requests, with only 11 reported through the 311 system in the past seven years, suggesting minimal resident issues requiring city intervention. The majority of recent service requests (all from 2024 to 2026) have been related to tree maintenance and waste management, including two tree trim requests, a blue recycling cart request, and a recycling pickup request. Two external repairs were also documented: a sign repair request in 2025 and a tree debris clean-up request filed in June 2026, which remains open as of the latest available data. The building's permit activity appears extremely limited, with only one building permit recorded in the past seven years. While the property has maintained basic services and addressed necessary maintenance issues, the limited number of permits and service requests suggests either minimal required improvements or potential underreporting of building conditions, though without direct access to the condition or system performance of the building, no conclusions can be drawn regarding current living conditions.

How 3519 S Union 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 3117 buildings in this neighborhood, 1434 are predicted to be safer.
