343 1st Avenue, Manhattan, NY 10003
343 1st Avenue is a 4-story, 6-unit old law tenement building located in Gramercy, constructed in 1910 and currently owned by Lawrence Lerner. The building's recent history shows a consistent attention to bedbug management, with annual reporting requirements being met from 2022 through 2025, though initial violations were noted in 2022-2024 for failure to submit reports. The building has maintained a clean record for bedbug infestations, with all annual filings indicating zero infested, eradicated, or re-infested units.
Rodent inspections have shown significant improvement over time, with the most recent inspection in May 2025 passing successfully. Historical rodent management between 2015 and 2018 suggests a proactive approach, with bait application occurring in early 2017 and some initial inspections showing rat activity, though subsequent years typically passed inspections. The building underwent some permitted work in May 2019, with plumbing and exterior work permits being issued under job number 123737563.
A Special Operations Compliance Inspection in 2021 found no violations, and both bedbug and rodent management practices have demonstrated compliance with city regulations. The building's maintenance records from 2019 to present show regular inspections and management of both bedbug and rodent issues, with no recent violations impacting resident safety or experience. The most recent bedbug report filing as of July 2025 shows continued adherence to reporting requirements, maintaining the pattern of zero infestations since 2019.
