886 Union Street, Brooklyn, NY 11215

The 4-story, 9-unit tenement building at 886 Union Street in Park Slope, built in 1907, has experienced persistent heating system issues in recent years. Most notably, there has been a troubling pattern of heat and hot water complaints throughout the building, with at least 10 documented incidents between October 2024 and March 2025, all classified as emergencies.

While HPD responded to these complaints and heat and hot water were reportedly restored in many cases, the frequency and recency of these issues suggest an ongoing HVAC system problem. The building also has a documented rodent history, with multiple inspections between 2018 and 2023 showing rat activity, including inspections in December 2022 and January 2023.

In terms of maintenance violations, Apartment 3A was cited in October 2024 for both mold (Class A violation) around a bathroom window and defective plastered surfaces in the bathroom (Class B violation), though these issues were subsequently addressed. The building has maintained compliance with bedbug reporting requirements, with no reported infestations in the past four reporting periods from 2021 through 2024. Other historical violations demonstrate a variety of maintenance issues, including a 2021 incident in Apartment 1A regarding excessively hot water (over 130 degrees F), and several 2021 violations related to building common areas, including inadequate lighting and cleanliness issues in the vestibule, all of which have been resolved.
