901 S Ashland Chicago

Little Italy, UIC, Chicago IL 60620 17173150680000 410 units · 1977

Nothing on record for this building in the last seven years, but our model still flags a rising risk of maintenance problems in the next 12 months. That forecast comes from the owner's wider portfolio and the surrounding area, not from this building's own record — treat it as a reason to ask questions, not as evidence of a problem. No public enforcement record to go on. Walk the building, ask the current tenants how repairs get handled, and get any promises in writing.

Initial analysis

The 410-unit residential building at 901 S Ashland Avenue, located in Chicago's Little Italy/UIC neighborhood, has been under the ownership of GRE Medical District C since its construction in 1977. Over the past seven years, the property has generated 22 service requests through the city's 311 system, with the most recent being a tree emergency in June 2026, followed by two air conditioning-related complaints and a general information call. The building's maintenance record shows some recurring issues, most notably with air conditioning systems, as evidenced by three separate no air conditioning complaints filed within a two-week period in May 2026 and August 2025. Other service requests include a stray animal complaint in August 2025, though this was likely an external neighborhood issue rather than a building-specific problem. The property's documented history shows minimal building permit activity, with only two permits issued in the past seven years, suggesting limited recent structural or major system modifications.

Risk rating

How 901 S Ashland Chicago'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.
