Unlock complete reportThe three-unit building at 7821 S Winchester Ave in Chicago's Auburn Gresham neighborhood, owned by Lucila Perez, has a mixed record since its construction in 1927. The property has experienced several notable issues over the past seven years, with a particular spike in service requests related to pest control, including a documented rat complaint in January 2026 and a dead animal removal request in June 2024, suggesting ongoing sanitation challenges in the vicinity. The building's violation record shows a total of 11 building violations over the same period, though specific details of these violations are not provided in the available data. While there have been five 311 service requests in the last seven years, several of these were simply information calls and not related to building conditions or complaints. The owner has applied for only one building permit during this timeframe, which could indicate limited investment in property improvements or maintenance.

How 7821 S Winchester Ave's risk score is calculated
