Unlock complete reportThe three-unit building at 1142 W Patterson Ave in Wrigleyville, owned by Robert H. Sallie and J. Kerr, is a 133-year-old property constructed in 1890. The building's recent history shows a notable cluster of winter-related maintenance concerns, particularly during December 2025, when there were consecutive complaints about uncleared sidewalks in early December, followed by two recycling pick-up requests (one of which was repeated) and a yard waste pick-up request later that same month. These winter maintenance issues suggest challenges with snow removal and waste management services in the area during that period. The building has relatively few documented incidents over the past seven years, with only 19 total service requests on record, though 13 of these have been specifically related to 311 complaints about the building itself. The property has maintained a clean record in terms of serious environmental issues since a single asbestos work order complaint from 1998, indicating that any potential hazardous material concerns have not recurred in recent decades.

How 1142 W Patterson 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 404 buildings in this neighborhood, 198 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
