Unlock complete reportThe five-unit residential building at 1800 S Throop St in Chicago's Lower West Side, constructed in 1891 and currently owned by Mark Falanga, has experienced several noteworthy issues over recent years. Most concerning are the seven open unresolved violations recorded in November 2022 related to Periodic Routine Inspections, which suggest ongoing compliance issues that have not yet been addressed. The building's maintenance history shows limited improvement, with only one building permit issued in the past seven years, a stark contrast to the 11 permits associated with the owner across eight total parcels. The property has been the subject of 59 service requests through the 311 system over the past seven years, with a significant cluster of these (six out of seven recent requests between April and June 2026) specifically addressing pothole issues in the street surrounding the building, though these external infrastructure concerns are separate from the building's condition. Historical records indicate environmental concerns from 2005, including complaints related to toxic hazardous materials and air pollution, though these are now quite dated. While the street maintenance issues are being addressed through 311 requests, the building's unresolved inspection violations warrant attention as they represent the most significant current concern regarding the property's condition and compliance status.

How 1800 S Throop St's risk score is calculated

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 3683 buildings in this neighborhood, 3646 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
