Unlock complete reportThe three-unit residential building at 917 N Ashland Ave in the West Town neighborhood, owned by Gary Treenkman, has maintained a relatively clean record since its construction in 2002. Over the past seven years, there has been only one documented building code violation, which remains open as of April 2025 related to a periodic routine inspection. The property has generated four 311 service requests during this period, with the most recent being a restaurant complaint in April 2026. The earlier 311 requests included another restaurant complaint in August 2025, a street pothole complaint in June 2025, and a building violation report in March 2025, all of which have been closed. While the number of complaints is not unusually high for a property of this nature, the pending building code violation from 2025 warrants attention as the most significant outstanding issue on record.

How 917 N Ashland Ave'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
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 2271 buildings in this neighborhood, 795 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
