Unlock complete reportThe four-unit residential building at 8131 S Stony Island Ave in Chicago's Avalon Park neighborhood, owned by Heidi Jones Keith, has experienced several notable issues in recent years. Most significantly, in August 2025, there was a concerning pattern of water-related problems, with two separate complaints about basement water issues and a leak inspection request within a two-day period. Additionally, the property experienced tree-related maintenance needs, including a tree trimming request and a clean-up request for tree debris in mid-2025. Looking further back into the building's history, there were environmental concerns documented in February 1993, when the property received two municipal code violations related to hazardous materials, resulting in fines of $300 each. While the tree maintenance and water issues have been addressed (as indicated by their "Closed" status), the frequency of water-related complaints in mid-2025 may warrant monitoring of any recurring moisture issues in the building.
