4311 W North Ave

The 4-unit residential building at 4311 W North Ave in Humboldt Park, owned by Miguel Ortega, was constructed in 1881 and has experienced several significant events over recent years. Most notably, in June 2021, the property was involved in multiple environmental enforcement actions, including one violation related to waste treatment and disposal that resulted in a non-suit ruling, and another regarding waste removal responsibilities that incurred a $1,500 liability penalty. A third environmental violation concerning permit requirements was also dismissed without penalties. The building's maintenance and incident history shows some concerning patterns, particularly in 2025, when there were three separate graffiti incidents requiring removal, and an open leak investigation was initiated in May 2026. While the building has only one recorded building permit in the past seven years and 12 total 311 service requests during this period, it's worth noting that the owner has multiple parcels beyond this property. The most recent service requests have included routine matters like a 311 information call in June 2026, though many previous requests from 2025 related to non-urgent issues such as parking code enforcement and graffiti removal. The property's historic air pollution complaint from 2014 was investigated and determined to be unfounded.
