Unlock complete reportThe six-unit building at 2309 W 51st Street in Chicago's Gage Park neighborhood, owned by Aildardo Sandoval, was constructed in 1967 and has experienced several notable issues over the past seven years. Most concerning are five open complaint-driven inspection violations documented on September 21, 2020, which remain unresolved in the building's record as of October 2023. While there was one permit-related inspection violation that was resolved as of August 2025, the persistence of the 2020 violations suggests an ongoing pattern of code compliance challenges. The building's recent maintenance record includes two 311 service requests in 2024—one for graffiti removal in June and another regarding a street light outage in April—both of which were closed, though these minor issues appear to be more related to building surroundings than the structure itself.

How 2309 W 51St St'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
