Unlock complete reportThe building at 3139 N Oconto Ave is a two-unit residential property located in Chicago's Dunning neighborhood, constructed in 1924 and currently owned by Myroslava Kham. The property has experienced two building code violations in the past seven years, both of which were recorded and resolved on May 19, 2020, through complaint-driven inspections. The building's record shows a relatively high volume of service requests, with 19 total 311 calls in the past seven years, though it's notable that the most recent six requests between August 2025 and May 2026 were all related to parking code enforcement issues and were properly closed out. The building's permit history shows only one building permit filed in the past seven years, though the nature and resolution of this permit is not specified in the available data. The property's total violation and service request counts are relatively low compared to many other buildings in the area, suggesting generally stable maintenance conditions, though the concentration of parking-related service requests in recent years indicates this has been a recurring concern in the neighborhood.

How 3139 N Oconto Ave's risk score is calculated
