Unlock complete reportThe 31-unit residential building at 1666 W Pratt in Chicago's Rogers Park neighborhood, owned by 1666 W Pratt LLC, has maintained a relatively clean record since its construction in 1957. Over the past seven years, there have been two building code violations related to permit inspections in October 2020, both of which have been resolved. The property has generated three 311 service requests during this period, with the most recent being a water lead test kit request in July 2025. Other service requests included a tree trimming request (which is no longer being accepted) in February 2025 and a pothole complaint in the street area near the building in June 2024. While these recent requests suggest the building management is actively addressing environmental concerns as they arise, it's worth noting that the building's last environmental complaint on record dates back to May 2002, with the specific nature of that complaint categorized as "Other." While the building's record shows no major patterns of violations or service requests that would significantly impact resident experience, the relatively low number of building violations and service requests over this extended period is worth mentioning.

How 1666 W Pratt Chicago'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 1536 buildings in this neighborhood, 1352 are predicted to be safer.
