Initial analysis

The property at 820 W 19th St is a two-unit residential building located in Chicago's Lower West Side neighborhood, dating back to 1878. The building's recent history from 2025 shows a concerning pattern of water quality concerns, with three water lead test kit requests in the summer and fall of 2025, two of which have been closed while one remains open as of September 2025. The building's record over the past seven years reveals significant activity, with a total of 557 service requests submitted by the owner, 46 building violations, 20 building permits, and 6 environmental enforcement actions (including 2 enforcement cases and 4 complaints). While the property is owned by an entity named "PI" with ownership of 63 parcels total, the specific nature and resolution of the building violations and environmental concerns is not detailed in the available records. The age of the building and its documented history of environmental testing requests suggest potential infrastructure and safety concerns, though it should be noted that water quality testing is often conducted as a precautionary measure even in well-maintained buildings.

Risk rating

How 820 W 19Th St'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.
