Unlock complete reportThe two-unit residential building at 2805 S Wells Street, located in Chicago's Armour Square neighborhood, has a documented history dating back to its 1888 construction. The property, currently owned by Yan Jin Mo, has maintained relatively low service request and complaint activity over the past seven years, with only two 311 service requests and one environmental complaint. The most recent service request occurred in January 2026 regarding garbage cart maintenance, while an earlier rodent baiting complaint was addressed in April 2025. The building experienced one environmental issue in May 2022 related to air pollution, which was resolved promptly within one day of the complaint being filed. The limited number of recorded complaints and service requests over this period suggests relatively stable building conditions, though the presence of both rodent and air quality issues indicates some environmental challenges have occurred in recent years.

How 2805 S 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
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 508 buildings in this neighborhood, 137 are predicted to be safer.
