Unlock complete reportThe property at 1850 N Sawyer Ave 1 in Logan Square is a two-unit, 129-year-old building owned by Dolores S Cotton. The building's record shows relatively few issues over the past seven years, with a total of 11 service requests logged through the Chicago 311 system, of which four were related to rodent baiting and rat complaints - the most recent of these occurring in May 2026. Other service requests included a garbage cart maintenance issue in August 2025, a sign repair request in June 2025, and a pothole complaint in April 2025. In terms of building improvements or modifications, only one permit was filed in the past seven years, though the specific nature of this permit is not detailed in the available records. While the building's maintenance record shows periodic attention to street-level issues and pest control measures, the relative infrequency of service requests over this extended period suggests a relatively stable property condition compared to other buildings with more frequent service needs.

How 1850 N Sawyer Ave 1'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 5177 buildings in this neighborhood, 3262 are predicted to be safer.
