1670 1st Avenue, Manhattan, NY 10128

1670 1st Avenue is a 4-story, 6-unit old law tenement building located in Manhattan's Upper East Side, built in 1920 and currently owned by Moshe Krengel. The building has experienced several recurring maintenance issues over recent years, with the most notable concerns being related to sanitation and building systems. In 2023, there were multiple complaints regarding unsanitary conditions, including pest infestations and garbage storage issues, though inspections did not result in violations.

The building has a documented history of mold problems, including emergency complaints in late 2021 and early 2022, along with multiple heat and hot water complaints in 2020 and 2021, though these were resolved without violations. Significant building-wide issues were identified in November 2021, including problems with ceiling paint/plaster, and several building safety violations remain open, including requirements for vestibule door repairs and proper signage. The building has undergone regular rodent inspections since 2016, with most recent inspections in 2023 and 2024 passing successfully.

While bedbug reports have been filed regularly from 2022 through 2025 showing no infestations, there was a low-pressure inspection violation recorded in 2023. The property has had multiple permits issued between 2018 and 2020 for various works, including plumbing and electrical installations, with routine maintenance and emergency work being conducted as needed. The building's maintenance history suggests ongoing challenges with building systems and sanitation, though many recent complaints have not resulted in official violations.
