Unlock complete reportThe two-unit residential building at 4725 S Kolin Ave in Archer Heights, owned by Juan Rios and constructed in 1964, has experienced notable activity in recent months, particularly in June 2026. The property currently shows three active unresolved complaints filed on June 15, 2026, including a building violation, business complaint, and a city vehicle sticker violation, with an additional vehicle sticker violation reported two days prior. These recent service requests suggest ongoing compliance and enforcement issues related to parking regulations and potentially other building-related matters. Looking at historical data over the past seven years, the property has maintained a total of 137 311 service requests and two building violations, though these appear to be relatively minimal compared to the current concentration of recent issues. The building's ownership record shows Juan Rios with three total parcels under his name, indicating some level of property portfolio management beyond this single building.

How 4725 S Kolin Ave 1'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

Out of 843 buildings in this neighborhood, 590 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
