4019 10th Avenue, Brooklyn, NY 11219

The property at 4019 10th Avenue in Borough Park is a three-story, four-unit residential building constructed in 1930, currently owned by Larry Sullivan. The building has experienced recurring maintenance issues throughout recent years, with particularly significant problems documented in 2021 and 2024. Notably, between January and November 2021, there were multiple violations related to heat and hot water systems, including inadequate service affecting both individual apartments and the entire building.

Other persistent issues included ceiling water leaks (both slow and heavy flow), lighting problems, and ceiling damage requiring attention. More recently, in May 2024, several concerning violations were documented, including exposed electrical wiring in public areas, mold conditions, and various maintenance deficiencies in the first-floor public hall. These violations included requirements for proper repair of fire escape access and necessary safety notices regarding carbon monoxide detection and gas leak procedures. The building has been subject to multiple investigations regarding potential illegal conversion or occupancy beyond its authorized four-unit designation.

Between 2019 and 2021, several complaints were filed regarding possible unauthorized unit conversions, with various inspection attempts resulting in inability to gain access. The property currently faces active Environmental Control Board violations from 2021, with penalties totaling $50,000 for failure to comply with correction orders related to allegedly illegally occupied units and work performed without proper permits. Two complaints from 2024 regarding emergency conditions (including door/window issues, mold, and electrical wiring) were promptly closed, indicating some responsiveness to immediate maintenance needs. An active complaint regarding the certificate of occupancy status was filed in September 2024 but was not accessible for inspection.
