New City, Chicago IL 60609 20043130150000 4 units · 1883

Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Initial analysis

The multi-unit residential building at 4435 S Union Avenue in the New City neighborhood is a 4-unit structure built in 1883 and currently owned by Salvador Campos. The property has experienced several notable events in recent years, with particular attention needed on the most recent open service requests from 2025: a water lead test kit request and an inspect public way request, both indicating potential ongoing safety and maintenance concerns. The building has a documented history of 112 service requests over the past seven years, of which three have occurred since 2024. There have also been six building violations recorded in the same period, though the specific nature and resolution status of these violations are not detailed in the available records. A completed service request for graffiti removal from May 2024 suggests recent attention to building aesthetics and security. Given the building's age, the presence of open water-related testing requests raises particularly important safety considerations regarding potential lead contamination.

Risk rating

How 4435 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

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.

Neighborhood percentile
