Unlock complete reportThe six-unit residential building at 906 N California Ave in Humboldt Park, owned by Gerardo Roldan, has shown relatively minimal activity on its official record over the past seven years, with only two 311 service requests and one environmental complaint directly associated with the building itself. Both service requests, recorded in April and October 2025, related to graffiti removal and were successfully closed. More notably, there was a construction and demolition-related environmental complaint filed in September 2023 that required referral to the Building Department, though this complaint was marked as resolved within a day. Looking at the broader ownership record, there is a significant discrepancy in the total 311 service requests, with the owner record showing 30 requests, though the nature of these requests is not specified in the building's summary. Additionally, the owner record shows only one environmental complaint, which appears to be the same construction-related issue noted in the building's summary. Given the age of the building (constructed in 1906), the relatively low number of reported issues over this extensive period is noteworthy, though it's important to consider that not all building conditions may be captured in public records.
How 906 N California 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, 5031 are predicted to be safer.
