Unlock complete reportThe two-unit residential building at 4946 S Karlov Ave in Chicago's Archer Heights neighborhood is owned by Elvia Ruiz and was constructed in 1918. The property has experienced a notably concerning pattern of issues in the current year (2025), with particular emphasis on water-related problems; there were four separate complaints about basement water issues between mid-August and late-August 2025, including two complaints filed through the Alderman’s office and two through 311 City Services. Additionally, the property has generated three other service requests in 2025, specifically two clean vacant lot requests (one in October 2025 and another in April 2025) and a shared housing/vacation rental complaint in May 2025. The building's recent service request history, particularly the cluster of basement water complaints, suggests ongoing maintenance challenges that could impact resident comfort and safety.

How 4946 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.
Out of 843 buildings in this neighborhood, 253 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
