Unlock complete reportThe four-unit residential building at 2509 W Thorndale Ave in Chicago's West Ridge neighborhood, constructed in 1926, is currently owned by Dien N Do. The property's recent maintenance history over the past seven years shows minimal service requests, with only three recorded incidents between December 2024 and July 2025. The most recent incidents, occurring in July 2025, involved two consecutive graffiti removal requests, both of which have been closed. Prior to these, there was a tree trimming request submitted in December 2024, though it's worth noting that this particular request type is no longer being accepted. The limited number of service requests and their nature, primarily focused on exterior maintenance rather than structural or safety concerns, suggests relatively few immediate issues affecting the building or its residents.

How 2509 W Thorndale 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.
