356 Union Street, Brooklyn, NY 11231

356 Union Street is a 5-story, 20-unit residential building located in Brooklyn's Carroll Gardens neighborhood, built in 1900 and currently owned by Michael Niamonitakis. The building has experienced recurring heat and hot water issues in recent years, with emergency complaints filed in both January 2025 and November 2022 regarding lack of these essential services throughout the entire building. While the 2022 incident was resolved with confirmation from a tenant that services had been restored, the 2025 complaint resulted in the Department of Housing Preservation and Development being unable to gain access to verify the conditions.

The building has also faced indoor air quality concerns, with a November 2024 complaint about chemical vapors that prompted the Department of Health and Mental Hygiene to issue an advisory to the owner. A notable inspection occurred in April 2021 when the building received a violation related to bedbug reporting requirements, though this was certified as corrected by May 2021. The building's bedbug reports from 2019 through 2024 show consistently zero infested or eradicated units, indicating effective pest management practices.

In terms of rodent control, the building had rat activity identified in December 2017, though a subsequent compliance inspection in February 2018 passed with no issues noted. The only Department of Buildings complaint on record from 2019 regarding permits was resolved with no violations found. While the building has experienced some maintenance issues, it's worth noting the prompt closure of most complaints and the regular filing of bedbug reports indicating active management of pest control.
