423 Amsterdam Avenue, Manhattan, NY 10024
423 Amsterdam Avenue is a 6-story, 15-unit old law tenement building located in Manhattan's Upper West Side neighborhood, built in 1888 and currently owned by Lawrence Arnsten. The building's recent history reveals several concerning patterns, particularly regarding pest control and maintenance compliance.
Most notably, there have been persistent rodent issues; while two rodent inspections in early 2025 passed, the building previously experienced multiple compliance failures in 2023, along with documented rat activity in late 2022, indicating a recurring challenge with pest control that has required bait application and multiple inspections. The building's pest management record shows some positive developments in recent years, particularly regarding bedbug reporting.
The 2024 bedbug report, filed in December 2024, documented no infested or re-infested dwelling units within the October 2023-October 2024 reporting period, demonstrating successful eradication efforts compared to the 2021 report which noted issues in all 15 units. However, the building has required multiple Housing Maintenance Code (HMC) violation notices in 2022 and 2024 regarding the filing of annual bedbug reports, suggesting occasional administrative oversights in compliance. The property has also experienced two food establishment-related complaints in 2022-2024 concerning rodents/insects/garbage and pesticide use, though these complaints were ultimately closed with reported resolutions.
