Unlock complete reportThe six-unit residential building at 4601 N Keystone Ave in Albany Park, owned by N Ahmed, has been in operation since 1924 and has generated a total of 17 service requests through the 311 system over the past seven years. The most recent incidents, from 2025-2026, primarily involved external infrastructure and public space concerns, including an alley pothole complaint and a tree emergency, both of which were resolved through the Department of Transportation and 311 City Services respectively. Two sanitation code violations were reported and addressed in the summer of 2025, along with a garbage cart maintenance issue and a stray animal complaint in August 2025. The building's service request history over the past two years shows a mixture of neighborhood-related issues rather than building-specific problems, with all reported matters being formally closed and resolved through appropriate city services.

How 4601 N Keystone 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 2730 buildings in this neighborhood, 2075 are predicted to be safer.
