Unlock complete reportThe two-unit building at 1024 N Keystone Ave, located in Humboldt Park and owned by Ricardo Maldonado, was constructed in 1911 and has experienced various maintenance and infrastructure issues over the past several years. The property has generated a total of 16 service requests through the city's 311 system since 2016, with the most recent concerns all occurring in 2026, primarily focused on street and alley maintenance issues including multiple pothole complaints. A sewer cleaning inspection request from June 2026 remains open, suggesting ongoing infrastructure maintenance needs. The building was previously subject to vacant/abandoned building violations in 2014 and 2015, specifically related to security and maintenance requirements under the city's vacant building ordinance, though these cases were disposed of through city non-suit with no fines assessed. While the property has had relatively few building permits issued in the past seven years (only two), the concentration of recent service requests regarding basic infrastructure maintenance - particularly in 2026 - indicates an ongoing need for attention to the building's immediate surroundings and basic services.
How 1024 N Keystone Ave 1St'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, 807 are predicted to be safer.
