Unlock complete reportThe two-unit residential building at 4523 N Sawyer Ave in Chicago's Albany Park neighborhood, owned by Daniel C Sanchez, has been standing since 1923. Over the past seven years, the property has had minimal official documentation, with only one building permit filed during this period. The property's service request history shows a total of 16 requests to the 311 system, with the majority (nine out of sixteen) related to yard waste or tree maintenance between September 2025 and April 2026. The concentration of service requests in the latter part of 2025 suggests the owner was actively addressing external maintenance concerns during that period, particularly related to yard waste management and tree maintenance, though it's worth noting that some requests were for services that the city had stopped accepting (as indicated in three tree trim requests). Since April 2026, there have been no reported service requests, which could indicate either reduced need for maintenance services or potentially an incomplete reporting period. With only one building permit on record in the past seven years, and considering the age of the structure, this property may benefit from regular maintenance checks, though there is currently no documented history of major structural or safety issues based on the available records.

How 4523 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
Lower risk — safer than most nearby
City inspectors rarely find violations here. Strong maintenance history and a clean complaint record.
Typical — about average for the neighborhood
Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.
Higher risk — riskier than most nearby
Elevated violation and complaint history. City inspectors have found issues here before and are statistically likely to again.
Out of 2742 buildings in this neighborhood, 768 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
