Unlock complete reportThe three-unit residential building at 831 W Altgeld Street, constructed in 1914 and currently owned by 831 W Altgeld LLC, has experienced several concerning incidents in recent months. Most notably, on August 26, 2023, four complaint-driven building code violations were recorded that remain unresolved as of the latest data update. The building's maintenance history shows some troubling patterns, with a cluster of six graffiti-related service requests in October 2025 alone, suggesting potential issues with property upkeep and security around that time. Other environmental and maintenance concerns in recent years include a December 2025 complaint about an uncleared snow sidewalk, though this was subsequently addressed, and a tree planting request from October 2025 that was marked as closed. The building's permit activity has been minimal, with only two permits recorded in the past seven years. The property's documented history extends back to 2012, when an air pollution complaint was filed and subsequently deemed invalid.
