Unlock complete reportThe six-unit residential building at 815 N Fairfield Ave in Humboldt Park, owned by Mark Hildebrand, dates back to 1893 and has experienced a range of maintenance and service requests over the past seven years. Most recently, in late 2025, there were two tree trim requests, though these are no longer being accepted, along with an injured animal report, sidewalk inspection request, alley pothole complaint, and street light outage complaint, all of which have been closed. The property has recorded a total of 90 service requests during the ownership period, with eight of these specifically coming through the 311 system. The building's violation record shows eight building violations over the past seven years, along with three house share violations, suggesting potential concerns in these areas. The property has received three building permits during this period, though the nature and scope of these permits are not specified in the provided data. Notably, the majority of recorded issues appear to be related to general maintenance and infrastructure concerns rather than safety violations, though the building violation and house share violation records merit attention.

How 815 N Fairfield 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, 4410 are predicted to be safer.
