Unlock complete reportThe six-unit multi-family building at 2621 S Princeton Ave A in Armour Square, owned by LONG CITY LLC, is a historic structure dating back to 1888. The property has experienced a number of maintenance and quality-of-life issues over the past several years, with a total of 10 documented building violations and 43 service requests made through the city's 311 system. Most notably, recent concerns in 2026 include a rodent baiting complaint and an open sidewalk inspection request, though the building's alleyway conditions have been a recurring theme, with three separate alley pothole complaints filed between 2024 and 2025, all of which were subsequently closed. Additional service requests include complaints about an abandoned vehicle (closed in December 2025) and a rat complaint (closed in May 2026). The building's permit activity over the past seven years has been minimal, with only six building permits issued, suggesting limited documented improvements or modifications to the property. While some issues have been addressed through the closure of various complaints, the pattern of maintenance-related service requests and violations indicates ongoing challenges with the property's upkeep and surrounding infrastructure.
How 2621 S Princeton Ave A'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, 442 are predicted to be safer.
