146 1st Avenue, Manhattan, NY 10009
The 11-unit, 4-story New Law tenement building at 146 1st Avenue, owned by Tzvi Wertenteil, was constructed in 1910 and has experienced a series of notable events in recent years. Most concerning is a heat and hot water emergency reported in November 2024 that was closed without proper inspection access to affected units. The building has also suffered from unspecified unsanitary conditions, specifically mold, in 2021, with similar access issues during investigation.
More recent structural concerns emerged in 2023, including two construction enforcement complaints - one in February which warranted no violation, and another in August that resulted in a violation related to obstructed exit passageways with a penalty of $1,250. Additionally, there are currently two active violations from June 2023 regarding failure to file external low-pressure inspections for 2018 and 2019. However, the building has maintained a relatively good record in other areas.
Bedbug reports dating back to 2018 through 2024 consistently show 0 infested dwelling units, indicating effective pest management. The property has also passed multiple rodent inspections conducted biannually from 2019 through 2025, showing compliance with health standards. A notable Housing Maintenance Code violation was recorded in 2021 regarding garbage bins in a public hall on the first story, though it was subsequently closed with certified compliance. The building's management should be aware of the recent heat/hot water issues and the construction-related violations, while also noting the positive records in pest control and rodent inspections.
