840 East 17th Street, Brooklyn, NY 11230

840 East 17th Street is a 6-story, 29-unit residential building constructed in 1940 in the Flatbush neighborhood, currently owned by Necha Schwartz. The building has experienced recurring maintenance and sanitation issues in recent years, with particular concerns about heat/hot water service and pest problems. Most notably, there have been multiple rat sightings reported in 2025 (March, June) and at least two instances of mold issues (February 2025) that resulted in HPD violations.

The building has a documented history of heat and hot water complaints, with several cases in late 2024 and 2025, though HPD inspections often found no violations. In late 2023, apartment 6D was found to have both roach infestation and defective kitchen faucet issues, which were subsequently resolved by late December 2023. The property has also faced various safety and maintenance violations, including issues with fire escape access (flower pots and an air conditioner obstruction), hallway maintenance (defective fire retardant material), and apartment-specific problems (defective carbon monoxide detector and entrance door issues in apartment 3C).

Recent inspections in 2025 indicated continued rodent activity, following earlier findings in April 2025. The building's management has filed regular bedbug reports, with no infestations reported since 2022, and the property has generally complied with bedbug reporting requirements. Two environmental control board violations related to elevator safety features were issued in 2022, and while the building had some issues with filing required energy benchmarking reports in 2019-2020, these violations were ultimately dismissed. The building's management has shown an ability to resolve most violations within designated timeframes, though access issues sometimes hindered inspections and resulted in some complaints being closed without verification of conditions.
