1789 Flatbush Avenue, Brooklyn, NY 11210

1789 Flatbush Avenue is a 4-story, 13-unit New Law Tenement building constructed in 1931 and currently owned by Mordechai Applebaum. The building has experienced persistent maintenance issues over recent years, with notable concerns about mold that have recurred in multiple apartments. Most recently, in 2025, there was a complaint about chemical vapors or odors that prompted a Department of Health advisory.

In August 2023, the Department of Housing Preservation and Development (HPD) received multiple complaints regarding various maintenance issues, including doors, windows, plumbing fixtures (sinks and toilets), and paint/plaster conditions, though inspections found no violations in many cases. The building has documented mold problems in apartments 3B and 4A (from 2019 and 2022 inspections), along with plumbing issues and multiple instances of paint/plaster deterioration. Safety concerns have been identified, including missing smoke and carbon monoxide detectors in apartment 2D in 2022, though these violations were later certified as corrected.

The property has maintained a bedbug-free record since 2020, with all reported infestations eradicated, and passed rodent inspections in 2016 and 2019. Recent housing maintenance complaints suggest ongoing challenges with building conditions, though many have been resolved without formal violations being issued. The building's permit history indicates several repair and maintenance work requests, with some permits remaining in process as of the most recent review.
