Unlock complete reportThe two-unit residential building at 4857 N Keystone Ave 2 in Albany Park, owned by Carlos Benitez, has been standing since 1910. Over the past seven years, records show a total of six 311 service requests associated with the property, all of which have been resolved. The most recent activity occurred in 2026, when the property experienced several tree emergency situations on April 27, with multiple complaints logged through different departments including City Services and the Alderman's office. Shortly thereafter, in May 2026, there was also a street light outage complaint registered and subsequently closed. Prior to these incidents, there was another street light complaint logged in May 2024, which followed a pattern of similar infrastructure-related issues that seem to have affected the property's immediate surroundings. The building's record over the past seven years shows relatively few service requests for a property of its age and size, though the recent cluster of tree-related incidents in 2026 may indicate particular attention required for the property's landscaping or surrounding green space.

How 4857 N Keystone Ave 2'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 2742 buildings in this neighborhood, 1042 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
