Unlock complete reportThe two-unit residential building at 4351 S Princeton Ave in Chicago's Fuller Park neighborhood, owned by Maricsa & Juan Sanchez, has a documented history dating back to its 1898 construction. The property's most recent and active service requests, as of 2026, have been heavily focused on tree-related matters, with three open cases in 2026 including a tree debris clean-up and a tree removal inspection, along with one previously closed emergency request. In late 2025, there were two tree trimming requests submitted around the same time, though it's notable that the city had indicated they were no longer accepting such requests. The building's record also shows one closed service request from November 2025 related to recycling pick-up. Over the past seven years, there have been a total of 11 service requests filed through the 311 system, with the majority (seven out of eleven) concerning tree maintenance issues, suggesting either an ongoing concern with local vegetation or an active approach by the owners to maintain the surrounding landscape. The relative age of the building and the small number of service requests in total (11 over 7 years) might indicate limited other maintenance or safety concerns, though the data primarily reflects external maintenance issues rather than internal building conditions.

How 4351 S Princeton 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 272 buildings in this neighborhood, 24 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
