Unlock complete reportThe two-unit residential building at 1034 N Keystone Avenue in Humboldt Park, dating back to 1911 and currently owned by Mercedes Lara, presents a mixed record of service requests and environmental complaints over recent years. The most significant recent activity involves a series of six consecutive parking code enforcement reviews between June and October 2025, all of which were subsequently closed. While these parking-related matters were addressed, their frequency during this period is notable. An environmental complaint regarding noise was filed and investigated in November 2025, though no violation was found upon resolution. Looking further back, there was one notable incident of illegal dumping in October 2020, which was resolved through a work order. The building's records show a total of 11 service requests and 2 environmental complaints over the past seven years, suggesting relatively low levels of reported issues for this property.

How 1034 N Keystone Ave's risk score is calculated
