3840 Flatlands Avenue, Brooklyn, NY 11234

The two-story residential building at 3840 Flatlands Avenue in Marine Park, owned by Stewart Gross, was constructed in 1931 and contains one unit. The property experienced a series of concerning maintenance issues in early 2019, including electrical problems (power outages and wiring), plumbing issues, and unsanitary conditions related to mold. More significantly, a January 2019 inspection revealed several open violations in Apartment 1, including the absence of carbon monoxide detectors, excessively hot water (over 130 degrees), unsafe electrical wiring with exposed wires in the kitchen, and notable insect infestations (cockroaches and mice).

There were also plumbing issues with a defective bathtub caulk in the bathroom. Since these incidents, there has been consistent monitoring and maintenance, with regular bedbug reporting showing zero infestations from 2019 through 2025. The building's most recent bedbug reports (2025, 2024, 2023) show no infested units or eradication requirements.

In April 2024, there was a violation issued regarding the filing of the annual bedbug report, though this appears to be more administrative in nature. The property had a wiring violation in early 2019, but subsequent inspections in 2022-2024 have shown no major violations related to electrical systems, plumbing, or unsanitary conditions. The building's maintenance record since 2019 indicates improved management, with no recent complaints showing the same pattern of multiple simultaneous issues as seen in early 2019.
