Unlock complete reportThe two-unit building at 646 N Monticello Ave in the Humboldt Park neighborhood, constructed in 1913 and currently under Taxpayer Of ownership, presents a complex maintenance history over the past seven years. The property has generated 2228 building violations during this period, which is particularly concerning given the relatively low number of 311 service requests (8731) and building permits (338), suggesting that not all issues may have been properly addressed through official channels. Environmental concerns have also been notable, with 10 enforcement actions and 33 complaints filed, though these represent a small fraction of the overall building violations. Most recently, there have been two garbage-related service requests in 2025-2026, including a missed pick-up complaint and an open request for garbage cart maintenance, indicating potential ongoing issues with waste management services at the property. Additionally, there have been three house share violations recorded, though the specific nature of these infractions is not detailed in the available data.

How 646 N Monticello Ave 1's risk score is calculated
