Augrented Insights Report for 3921 7th Avenue

This 5-unit, 3-story OLD LAW TENEMENT building located at 3921 7th Avenue in Sunset Park, owned by Xiu Qin Xie and constructed in 1935, has experienced persistent maintenance and pest control challenges in recent years. Most notably, the property currently has several open Housing Maintenance Code violations as of April 2024, including an active cockroach infestation in apartment 2R, safety issues with self-closing doors, and various administrative code violations related to public safety notices.

The building has a documented history of rodent problems, with multiple 311 complaints in 2023-2024 revealing issues with garbage/recycling storage and rodent sightings. While some pest control measures have been attempted, including bait application in April 2024, inspections consistently indicate rat activity. The building's maintenance record shows significant compliance issues with required external low-pressure inspections, with violations issued for failure to file inspection reports from 2018-2023.

Previous inspection records reveal a fluctuating pattern of rodent control effectiveness, with the most recent December 2024 inspection again showing rat activity. Multiple Housing Maintenance Code complaints have been logged regarding unsanitary conditions, particularly concerning garbage storage. Though some violations have been closed, many remain open as of the latest available data from 2024, suggesting ongoing maintenance challenges that may affect resident quality of life.
