Unlock complete reportThe four-unit residential building at 634 N Sawyer Ave in Humboldt Park, owned by RMRE Holdings LLC, has a fairly clean record over the past seven years since its construction in 1915. The property has only one documented building code violation, which occurred in August 2019 during a permit-related inspection, though this issue has since been resolved. In terms of service requests, there was only one recorded instance through the 311 system, which took place on November 19, 2025, and was classified as an "Information Only" call to city services, with the matter having been closed without indicating any specific building issues. The limited number of violations, service requests, and permits on record suggests relatively stable building maintenance and operations, though it's worth noting that the 311 service request was made two years in the future from the current date of October 2023, which could indicate either an error in the record or the request being made for future reference.
How 634 N Sawyer 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 6211 buildings in this neighborhood, 5279 are predicted to be safer.
