Unlock complete reportThe two-unit residential building at 4121 W Arthington St in Garfield Park, owned by McConnell Estates LLC, has been standing since 1893. The property has experienced a total of 9 building violations and 14 service requests over the past seven years, with significant activity occurring in 2021 when six complaint-driven violations were documented on June 24, all of which have since been resolved. There is one unresolved permit-related violation from December 2019 that stands out in the record. More recently, the building has generated multiple 311 service requests in 2025, including three related to garbage cart maintenance (May and October), two for weed removal (August), one sanitation code violation (September), and one snow-related request (March 2026). While many of these service requests appear to relate to routine maintenance and environmental upkeep, the presence of a 2019 open violation and the cluster of complaints in 2021 merit particular attention in evaluating the building's recent historical maintenance pattern.
