Unlock complete reportThe 16-unit, 1916 brick building at 841 W Windsor in Chicago's Uptown neighborhood, currently owned by WINDSOR 16 LLC, has experienced significant regulatory attention in recent years. The property has accrued 29 building violations and 21 service requests over the past seven years, with most concerning recent activity occurring in 2025-2026. Particularly notable is the cluster of unresolved building code violations from 2025-2026, including multiple periodic routine inspections and a complaint-driven inspection. During 2025, while the property did undergo some permit-related inspections, which were resolved successfully, the building's ongoing violations suggest continuing regulatory scrutiny. The 311 service request history shows a range of issues being addressed, including safety concerns with lead water contamination (both test kit requests and lead inspection requests), building violations, and nuisance complaints, all of which have been closed. Historical records from 1993 indicate a past incident involving hazardous materials, though there is no recent pattern of environmental complaints.

How 841 W Windsor 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
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 1231 buildings in this neighborhood, 997 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
