Unlock complete reportThe 5-unit residential building at 509 N Wells St in River North, owned by PMD Company, has a documented history dating back to its construction in 1895. Over the past seven years, the property has experienced 100 service requests, including recent issues such as a sidewalk inspection request and multiple graffiti removal requests in 2025 and 2026. The building has three documented violations, though the specific nature and resolution of these violations are not detailed in the available records. Environmental concerns have been noted, with two enforcement actions and nine complaints filed, including a noise complaint from 2000. The property has also required six building permits in the past seven years, though the specifics of these permits are not detailed in the record. Recent service requests include a closed garbage cart maintenance issue and a cab feedback request that remains open as of June 2026. While the building shows regular maintenance and service requests typical of a property of its age, the concentration of recent graffiti issues and the open sidewalk inspection request may warrant monitoring for potential impacts on resident quality of life.

How 509 N Wells 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 184 buildings in this neighborhood, 46 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
