Unlock complete reportThe two-unit residential building at 3431 W Melrose St in Chicago's Avondale neighborhood, owned by Melissa Ontiveros, has been standing since 1901 and has experienced several notable occurrences over the past three years. The property has a documented pattern of rodent-related issues, with three rat complaints filed between 2024 and 2025 (September 2024, May 2025, and September 2025), indicating an ongoing pest management challenge in the vicinity. Additionally, there have been two complaints regarding abandoned vehicles near the property, one in April 2024 and another in March 2026, though these are external issues not directly related to the building's condition or management. In March 2025, there was a request for garbage cart maintenance, which suggests there may have been some concerns about waste management facilities at that time. While all reported service requests have been officially closed, the frequency of rodent complaints within this relatively short timeframe (three incidents across two years) stands out as the most significant pattern in the building's recent history.

How 3431 W Melrose St's risk score is calculated

What the score means for you
Lower risk — safer than most nearby
