156 1st Avenue, Manhattan, NY 10009
156 1st Avenue is a 6-story, 22-unit Old Law Tenement building constructed in 1900 and currently owned by Louis R Donzelli. The building has experienced numerous maintenance and safety issues over the past several years, with the most pressing concerns including open violations related to pest control, building facade maintenance, and safety equipment. As of June 2025, there is an open Emergency Housing Maintenance Code complaint regarding unsanitary conditions and pests.
The building has multiple active violations related to failure to file external low-pressure inspections for 2022-2023, and there are several unresolved facade issues with documented structural concerns, including cracks and damage to decorative elements. Notably, there were significant maintenance lapses in 2023-2024 involving building-wide heat and hot water outages, and recurring problems with pest infestations were documented throughout 2023. The building has also faced challenges with compliance during inspections, with multiple instances where inspectors were unable to gain access to units for necessary evaluations. The property's inspection history reveals ongoing concerns with safety systems and building maintenance, including open violations from 2023 regarding missing fire safety equipment (smoke and carbon monoxide detectors) in Apartment 17.
There have been multiple documented instances of unauthorized work, particularly in late 2018 related to renovation activities that compromised fire safety features, and issues with gas line modifications. The facade has been a particular focus of regulatory attention, with multiple ECB violations noting disrepair of decorative elements and building surfaces, resulting in significant penalties. While recent rodent inspections in 2025 show passing results, there was notable rodent activity documented in early 2023. The building's history shows recurring maintenance and safety compliance issues, with many violations remaining open or having been resolved only after significant delays or penalties.
