Unlock complete reportThe four-unit building at 1907 N Karlov Ave in the Hermosa neighborhood is a historic property dating back to 1891 and currently owned by J & B Santoyo. The building's recent service request history, covering the past seven years, shows a relatively low maintenance record with only two reported issues, both of which were graffiti removal requests filed in September and December 2024. Both requests have been resolved and marked as closed. While the property has experienced minimal documented issues in recent years, with only two service requests recorded in this period, the relatively limited number of complaints may suggest either effective property management or potential underreporting of maintenance issues.

How 1907 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
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 1618 buildings in this neighborhood, 971 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
