Unlock complete reportThe two-unit residential building at 6320 W Patterson Ave, located in Chicago's Dunning neighborhood, is a 1923 construction currently owned by Hector Frrea & Humbert. The property has generated a total of 10 service requests through the 311 system over the past seven years, with all but one of these matters being resolved.

A shared cost sidewalk program request remains open as of January 2025.

How 6320 W Patterson 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
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.
