790 Grand Street, Brooklyn, NY 11211

The three-story, two-family house at 790 Grand Street in Williamsburg, built in 1899 and currently owned by Jay Gruen, has experienced numerous maintenance issues and violations over the past several years. Most recently, in 2024, the building was cited for multiple violations including a roof leak near the skylight on the third story, broken entrance door lock, and ongoing garbage storage problems in the center court area. There have been recurring heat and hot water issues, with complaints in March and May 2023 that required emergency responses.

The property has a documented history of rodent problems, with multiple inspections showing rat activity between 2021 and 2023, and several bait applications. The building experienced water-related issues in late 2022, including slow leaks and ceiling problems that prompted multiple violations. The Department of Buildings has conducted several investigations regarding potential illegal conversions, with inspections in 2019, 2020, and most recently in 2024, though access was consistently denied.

Environmental Control Board violations from 2019 indicate unauthorized occupancy changes and improper installation of window units, though these were resolved without penalties. The building's most recent bedbug reports from 2023 show no infested units during the 2022-2023 reporting period, suggesting effective pest management. An active violation remains regarding the failure to file the 2017 boiler inspection report, and there are ongoing concerns about sanitary conditions, particularly related to garbage storage and pest management, as evidenced by both 311 complaints and HPD violations.
