Unlock complete reportThe 8-unit residential building at 1628 W Ohio Street in Chicago's West Town neighborhood, owned by Mark Hildebrand, has a documented history dating back to its 1878 construction. The property has experienced several significant issues in recent years, particularly in 2025-2026, with multiple animal-related complaints and ongoing infrastructure concerns. Notable recent incidents include three animal complaints in June 2026 (vicious and nuisance animals), an open tree emergency, a street light outage, and a rodent infestation complaint in late 2025. The building has also been linked to two open environmental concerns as of late 2025, specifically a water lead testing request and a tree emergency since June 2026. The property's historical violation record shows 8 building violations and 3 house share violations over the past seven years, though the specific nature of these violations is not detailed in the records. The building's service request history with the city includes 90 owner-initiated requests, suggesting regular interaction with municipal services, though the total number of building permits pulled in this period is relatively low at 3. A historical noise complaint from May 2011 adds to the property's documented issues, though this is now over a decade old.

How 1628 W Ohio Chicago's risk score is calculated

What the score means for you
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
