Initial analysis

The two-unit residential building at 3045 S Karlov Ave in the Little Village neighborhood, owned by Mario Carrillo Guzman, has maintained relatively low activity on record over the past seven years, with only three documented 311 service requests. The building, constructed in 1895, has experienced three distinct issues requiring municipal attention: a rodent infestation complaint in October 2024, a street light outage in January 2026, and a graffiti removal request in February 2026. All three incidents have been successfully resolved according to the records, with the most recent two occurring within the first two months of 2026. While the presence of these service requests indicates periodic maintenance and safety concerns in the vicinity, it is worth noting that the total number of complaints over this seven-year period equals the minimum required for reporting, suggesting either relatively low incidence of issues or potential underreporting in this older two-unit building.

Risk rating

How 3045 S 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.

Neighborhood percentile
57thpercentile
