340A Lenox Avenue, Manhattan, NY 10027

340A Lenox Avenue is a 5-story, 13-unit old law tenement building located in Harlem, constructed in 1900 and currently owned by Josh Pfeifer. The building has experienced persistent rodent-related issues, with multiple 311 complaints and inspections between 2023 and 2025 showing regular rat sightings, particularly in mid-2023, and ongoing bait application through mid-2025. The property has also faced significant heating and hot water system challenges, particularly in early 2023, with multiple emergency complaints filed through the Department of Housing Preservation and Development (HPD) for entire building heat and hot water issues, though some inspection access issues were noted.

Violations related to building maintenance were documented, including C-class violations in 2023 for inadequate heat supply, water issues, and access problems to the heating system, as well as self-closing door issues in apartments 1A and 4C. More recently, in mid-2023, there were serious structural concerns raised about the building, with complaints regarding shaking and vibration and issues with the masonry facade. These resulted in some violations regarding the need for sidewalk sheds for public safety, and the property was placed under structural monitoring.

An Environmental Control Board violation was issued in October 2023 for failure to comply with a Commissioner's order regarding structurally deficient conditions, resulting in a $2,500 penalty. However, the building has consistently maintained a bedbug-free record over the past several years, with no reported infestations or eradications from 2021 through 2024. The property has also had multiple violations dismissed through the Department of Buildings for administrative reasons, including failures to file various inspection reports between 2019 and 2020. While there have been multiple pest control interventions, particularly for rats, the building's management has been active in addressing most code violations when they are identified, as evidenced by the closure of many historical violations once resolved.
