506 West 157th Street, Manhattan, NY 10032

The three-story, two-unit building at 506 West 157th Street in Washington Heights, owned by Mike Ma, has experienced several significant maintenance and health concerns over recent years. Most notably, there is an active pattern of rodent activity, with multiple inspections in 2024 (including October, September, November, and December) documenting ongoing rat presence.

The building has also faced challenges with sanitary conditions, particularly regarding garbage and recycling storage, as evidenced by a 2023 HPD complaint that, while inspected and closed without violations, highlighted some maintenance concerns. The property has been cited for failing to submit required annual bedbug reports to HPD, with open violations listed from inspections in March and April 2024, though previous years had no reported infestations. Additionally, there are multiple active violations related to external low-pressure system inspections, with failure to file documentation noted for 2018 through 2023, suggesting ongoing compliance issues with this safety requirement.

The building's history includes various 311 complaints, with a notable cluster of rodent-related issues in 2022, and a 2022 Department of Buildings complaint regarding an "Open and Unguarded" condition that was eventually corrected in 2024. Inspection records show a mixed pattern of rat activity and baiting efforts, with several treatments applied in early 2023. While the property has passed some inspections and had certain complaints resolved, the recurring issues with rodent activity, unfiled inspection reports, and bedbug reporting violations indicate ongoing challenges with building maintenance and compliance requirements.
