Unlock complete reportThe property at 4333 N Saint Louis Ave Rear in Chicago's Irving Park neighborhood is a two-unit residential building owned by Frances Mason, dating back to 1905. The building's recent service history over the past seven years shows relatively few maintenance issues, with a total of five documented 311 service requests, all of which have been resolved. The most frequent concern has been related to street infrastructure, with three separate pothole complaints filed in May and June of 2024, all of which were closed appropriately. The most recent service requests in 2025 and 2026 pertained to garbage cart maintenance, which indicates attention to waste management services. While the frequency of pothole complaints in 2024 might suggest a temporary infrastructure issue in the surrounding area, there's been a noticeable shift towards routine maintenance matters such as garbage cart upkeep in more recent years. It's worth noting that all recorded service requests have been properly closed, suggesting appropriate responsiveness to maintenance needs, though the limited sample size should be considered when evaluating overall building conditions.
