525 W 31St St
Nothing on record for this building in the last seven years. Our model still sees a moderate chance of maintenance problems in the next 12 months, from the owner's wider portfolio and the surrounding area rather than from anything recorded here. 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 Bridgeport average of 1.0.
The bar and the rating point different ways because they measure different things: the bar counts building violations already on file, the rating forecasts the next 12 months.

Unlock complete reportThe four-unit building at 525 W 31st Street in Chicago's Bridgeport neighborhood is a 132-year-old property currently owned by Shun Chen. Over the past seven years, the building has generated a relatively low volume of service requests, with a total of six recorded 311 service calls. The most recent service request, filed in February 2026, remains open and pertains to sign repairs. The building has experienced recurring issues with graffiti, with three documented removal requests between 2024-2025, all of which have been closed. Two sign repair requests were submitted during this period, with one in September 2024 being resolved. The property also experienced a tree emergency in July 2024 that was addressed by city services. Throughout this period, only one building permit has been recorded, suggesting limited recent construction or modification activities. Given the building's age and relatively low number of service requests, most of which are related to external maintenance rather than internal systems, the property appears to have maintained basic stability, though the recurring graffiti removal needs indicate some ongoing challenges with the building's exterior maintenance.

How 525 W 31St St'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 3132 buildings in this neighborhood, 2662 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
