Unlock complete reportThe two-unit residential building at 1512 S Karlov Ave, owned by Oscar Delgado, has experienced a notable series of sewer-related maintenance issues in recent months, with multiple ongoing open requests for sewer cleaning inspections and water-related complaints. Most significantly, between April and June 2026, there have been at least seven sewer cleaning inspection requests and two water-on-street complaints, four of which remain unresolved as of the most recent data update. This pattern of recurring water and sewer problems suggests ongoing infrastructure challenges that could impact resident quality of life. While the building has two units and is over one hundred years old (built in 1906), it is important to note that this recent cluster of sewer-related issues represents a more concentrated pattern of service requests than typically observed in building records, warranting attention to the building's current plumbing infrastructure conditions. Over the past seven years, the property has generated a total of 14 service requests and has recorded six building violations, though these earlier issues are less informative given the recent focus on water and sewer problems.

How 1512 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

Out of 3676 buildings in this neighborhood, 845 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
