Initial analysis

The 9-unit residential building at 1644 W Sherwin in Chicago's Rogers Park neighborhood, owned by 1644 Sherwin LLC, has maintained a relatively clean record since its construction in 1963. Over the past seven years, there has been only one recorded building code violation, which occurred in December 2019 during a periodic routine inspection; however, this issue was promptly resolved. The property has generated minimal 311 service requests during this period, with two tree-related incidents reported on November 5, 2024, including both an emergency situation and a clean-up request, both of which have since been closed. Most recently, on January 16, 2025, there was a plumbing violation reported through the 311 system, which has also been closed. While the building has experienced these few maintenance issues and service requests, particularly in the realm of tree management, the overall records suggest regular compliance with building codes and prompt attention to reported concerns by the current ownership.

Risk rating

How 1644 W Sherwin Chicago'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.
