20 W Chestnut Chicago
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.
This building has 0 building violations (7y), at or below the Rush & Division average of 5.6.

Unlock complete reportThe 10-unit residential building at 20 W Chestnut in Chicago's Rush & Division neighborhood, owned by 18 Chestnut, Inc., has a relatively clean service record, particularly in recent years. Built in 1908, this property has generated only three 311 service requests in the past seven years, with the most recent occurring in July 2025 for a dead animal pick-up, followed by a tree trimming request in November 2024 and a parking code enforcement review in October 2024 - all of which have been resolved. Looking further back into the building's history, there was a noise complaint registered in June 2002, though this appears to be the only environmental issue on record. The limited number of service requests and complaints over such an extended period suggests generally stable building conditions, with no significant recent issues affecting resident experience or safety.

How 20 W Chestnut 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.
Out of 52 buildings in this neighborhood, 23 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
