Unlock complete reportThe six-unit residential building at 11136 S Vernon Ave in Chicago's Roseland neighborhood, owned by Christopher Montgomery, has experienced several notable issues over recent years. Most concerning is the pattern of unresolved building code violations, with multiple complaint-driven inspections occurring in both April 2022 and April 2026, along with a previous complaint-driven inspection in October 2019 that was resolved. The building's violation history over the past seven years shows a total of eight building violations, with a particular cluster of four in 2022 and two in 2026 that remain open as of the most recent data. The property has minimal recent 311 service requests, with only one recorded in the past seven years (a vicious animal complaint in May 2024 that has since been closed), suggesting limited tenant-reported issues through that channel. While the owner, Christopher Montgomery, holds five total parcels in his name, the building itself has only been associated with three building permits in the same seven-year period. The persistence of open building code violations, particularly those concentrated in 2022 and 2026, warrants attention, though it's worth noting that not all violations may directly impact resident safety or comfort.

How 11136 S Vernon Ave's risk score is calculated

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
