Unlock complete reportThe three-unit residential building at 3601 N Pioneer Ave 1 in Chicago's Dunning neighborhood is a three-unit property owned by Roy A Mattioli, constructed in 1964. The building's recent maintenance history over the past seven years has been notably centered around tree-related issues, with a cluster of five tree service requests in 2024-2026, including two emergency responses and a current open inspection request for tree removal. The property has also experienced some infrastructure challenges, evidenced by a sewer cave-in inspection request in September 2025, though this was subsequently closed. Additional external maintenance needs have included responses to a street light outage (2025) and tree debris clean-up (2025), both of which were resolved. While the building has required attention to various infrastructural and ecological elements, all reported issues have been addressed through proper channels, with the exception of the currently open tree removal inspection request initiated in April 2026.

How 3601 N Pioneer Ave 1's risk score is calculated
We trained a model on 7 years of Chicago code enforcement data — building violations, 311 complaint history, environmental enforcement, and owner track records. It estimates the probability that the City of Chicago will find a code violation at this address in the next 12 months. Lower % = safer.
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

Out of 1070 buildings in this neighborhood, 118 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
