Unlock complete reportThe two-unit residential building at 1647 N Karlov Ave in Humboldt Park, owned by Joshua A Johnson, is a 1910 structure with a relatively minimal service record over the past seven years. The property's documented 311 service requests, totaling four, all fall within the period from 2024 to 2025. These requests encompass a range of municipal matters, including a tree trim request, an abandoned vehicle complaint, a sign repair request, and one information-only call to city services. Notably, none of these service requests appear to directly relate to the building's structural integrity, systems, or resident-specific concerns, and all have been marked as closed. The lack of building-specific complaints or service requests over this period may suggest either stable building conditions or potentially limited reporting patterns.
How 1647 N Karlov 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, 3106 are predicted to be safer.
