767 Union Street, Brooklyn, NY 11215
The 10-unit, 4-story old law tenement building at 767 Union Street in Park Slope, owned by Nicholas Kotsonis, has experienced ongoing maintenance and quality-of-life challenges over recent years. Most notably, there have been three concerning heat and hot water complaints since 2023, with the most recent occurring in January 2024 when HPD was unable to gain access for inspection.
The building has also faced significant pest-related issues, including a July 2023 complaint about unsanitary conditions and multiple rodent issues in 2021, which required repeated bait applications and inspections showing rat activity during mid-2021. Apartment 6 has been the focus of multiple Housing Maintenance Code violations in 2023, including issues with peeling paint, mold around the bathtub, and concerns about window guards and self-closing doors, though these were certified as corrected by May 2023. The building's regulatory history shows attention to safety requirements, with some open violations from April 2023 concerning building access to the heating system and a main entrance door issue in Apartment 7A, though these are of a technical nature.
The property has maintained consistent bedbug management practices, with reports from 2021 through 2025 showing no infested units, and there is documentation of rodent control efforts in 2021. Three building permits were issued between 2019-2020 for electrical and plumbing work, suggesting regular maintenance and upgrades to building systems. While the record shows active management of various issues, the recurring nature of heating and pest problems indicates ongoing building maintenance challenges.
