339 Union Street, Brooklyn, NY 11231
339 Union Street is a 3-story, 4-unit residential building located in Carroll Gardens, Brooklyn, owned by Catherine Diam-valla and constructed in 1920 as a New Law tenement.
The building has a documented history of bedbug reporting requirements, with Housing Maintenance Code violations recorded in both 2021 and 2023 for failing to file the annual bedbug report. However, recent filings indicate an impressive record of pest management within the building.
The most recent bedbug report filed in July 2025 (covering the 2023-2024 period) showed no infested units, and this pattern of infestation-free status extends back through multiple reporting periods, including filings in December 2023, December 2021, and May 2021. Each of these prior reports consistently documented zero infested units, zero eradicated units, and zero re-infested units, suggesting that while the building had initial compliance issues with report submission, its current condition shows effective pest management and successful eradication protocols have been implemented and maintained.
