Unlock complete reportThe two-unit residential building at 1704 N Keystone Ave in Humboldt Park, owned by Palemon Barrera, has been in existence since 1916 and has generated a total of 12 service requests over the past seven years. The most recent record from 2026 shows three open sign repair requests within late May 2026, though the nature of these signs is not specified. Prior to these requests, the building's service record includes a variety of municipal service calls, all of which have been resolved except for the recent sign issues - including a closed 311 information call in May 2026, a blue recycling cart request through the Alderman's office in April 2026, a pothole complaint in February 2026, and a closed graffiti removal request through the Alderman's office in January 2026. Given the building's age and service request history, the most pressing current maintenance issue appears to be the two open sign repair requests from late May 2026.

How 1704 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 6211 buildings in this neighborhood, 3913 are predicted to be safer.
