Unlock complete reportThe two-unit building at 3635 S Prairie Ave in the Douglas neighborhood, owned by 3D Entities Inc, has experienced a relatively low volume of service requests and permits over the past seven years, with records showing 11 service requests and only one building permit. The most recent set of service requests from 2026 primarily concerns waste management issues, including a missed garbage pickup, and maintenance of recycling and garbage carts, though these are routine municipal service matters rather than building-specific concerns. Of particular note is an open water lead test kit request from December 2025, which represents the only building-specific health and safety concern recorded in the system, alongside an alley pothole complaint from the same month that likely affects access to the property. The building's documented history shows no significant safety violations, emergency incidents, or major maintenance issues, though the limited scope of available data should be considered when assessing the building's overall condition and amenity status.

How 3635 S Prairie Ave'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
Grade A–B — Low risk
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Grade C — Moderate risk
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Grade D–F — High risk
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 302 buildings in this neighborhood, 66 are predicted to be safer.
