Unlock complete reportThe two-unit residential building at 1135 W Patterson Ave, owned by Karen Amos, has been part of the Wrigleyville neighborhood since its construction in 1899. The property's recent history, dating back over the past seven years, shows some cause for concern, particularly with two unresolved building code violations recorded on July 14, 2021. While these complaint-driven inspection violations remain open, it's important to note that this is the only instance of building code violations on record during this period. The property has also generated one 311 service request in the same seven-year timeframe, which was related to garbage cart maintenance and was closed as of August 22, 2025. This request appears to be a routine maintenance issue and not directly related to the building's structural or safety conditions. The limited number of reported issues over this extended period, while concerning in the case of the open violations, suggests that major recurring problems have not been a significant issue for this property.

How 1135 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, 327 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
