Unlock complete reportThe three-unit building at 5401 S California Ave in Gage Park, owned by Sergio Morales, is a 1923 structure that has experienced a significant number of regulatory interactions over the past seven years. The property has accumulated ten building code violations during this period, with the most recent cluster of violations occurring in 2024, where three separate complaint-driven inspections were conducted between July and December. While most of these violations have been resolved, there remains one open violation from June 2023 that has not been addressed as of the current date. The building has also generated a notable volume of 311 service requests, totaling 35 under the owner's name, with the most recent occurring in May 2026. These requests have covered various issues, including multiple business complaints, building violations, and a pothole complaint in the street, all of which have been closed except for the most recent one regarding a building violation from October 2025. Notably, there has been only one building permit issued under this ownership during the seven-year period, which may indicate limited permitted modifications to the property or improvements to address existing violations.

How 5401 S California 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 1787 buildings in this neighborhood, 1769 are predicted to be safer. The band is relative to this neighborhood, so a share of every neighborhood falls in each colour.
