Unlock complete reportThe two-unit building at 1736 S Union Avenue in Chicago's Lower West Side, constructed in 1888 and currently owned by Brent Fagerburg, has experienced several noteworthy incidents over the past seven years. Most concerning is a pattern of water-related issues, with three separate no water complaints recorded in January 2025 alone, and an additional no water complaint in January 2026, suggesting potential plumbing infrastructure challenges. The building has also faced two incidents requiring graffiti removal in late 2024, occurring in September and November of that year. An abandoned vehicle complaint was made and resolved in December 2025, though this seems to be related to street conditions rather than an issue directly affecting the building itself. While the total of ten 311 service requests over seven years is relatively low for a residential property, the recurring nature of the water complaints stands out as the most significant pattern in the building's recent history.

How 1736 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.
Out of 3683 buildings in this neighborhood, 1400 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
