5909 7th Avenue, Brooklyn, NY 11220

5909 7th Avenue is a three-story, four-unit New Law Tenement building constructed in 1922 and currently owned by Lam Wong. The building has experienced several significant compliance issues in recent years, most notably during 2021 when multiple Open Housing Maintenance Code violations were recorded, including the lack of proper safety postings related to carbon monoxide detectors, gas leak procedures, and smoke detector requirements in the first-story public hall. During the same inspection period, there were also violations regarding the improper placement of required inspection certificates and heating system keyholder notifications.

In 2019, an important elevator inspection violation was recorded related to the failure to file the required Category 1 inspection/test documentation, though this was later dismissed when the associated penalty was paid. The building had unauthorized alterations issues in 2018-2019, including occupation of basement and first-floor spaces as a physical therapy office without proper permits, resulting in Environmental Control Board violations and penalties. More recent developments show some improvement in compliance. The building has passed rodent inspections as of February 2023 and has maintained a record of zero reported bedbug infestations in the past three filing periods (2019-2025).

The most recent Bedbug Reporting from May 2025 indicates no units have been infested, eradicated, or re-infested during the 2023-2024 period. While there were previous bedbug reporting violations in 2021-2024, these appear to have been resolved, and the building's current bedbug status is in compliance. A permit was issued in August 2022 for work classified under both electrical and plumbing categories, suggesting some level of maintenance or improvement work has been undertaken. Separate complaints regarding construction work and Local Law 188 compliance were recorded in 2020-2022, though these were either closed without violation or resulted in no warranted violations upon inspection.
