1806 48th Street, Brooklyn, NY 11204
The four-story, 39-unit New Law Tenement building at 1806 48th Street in Borough Park, owned by Charles Knoll and constructed in 1923, has experienced persistent heating and hot water issues, particularly during the winter months. Most notably, from December 2023 through December 2024, there were multiple HPD complaints and violations regarding inadequate heat and hot water, affecting both individual apartments and the entire building. In December 2024, violations were issued for inadequate hot water throughout the building, though some inspections were hindered by lack of access to certain apartments.
The building also underwent several safety inspections in December 2024, revealing multiple violations in Apartment B6, including issues with smoke detectors, carbon monoxide detectors, window guards, door locks, and hot water fixtures, all of which were subsequently certified as corrected in early 2025. Additional building-wide violations were noted regarding the building entrance door lock, heating system access, and public area maintenance. The building has an active Department of Buildings violation from April 2021 regarding energy efficiency score display requirements.
Bedbug reports indicate only one infested unit was reported in the most recent filing period (2023-2024), though there was a previous incident in 2020 involving one unit. The property has consistently passed rodent inspections in recent years, with successful compliance noted in 2012 and 2022. Various door and window-related issues have been reported, including violations for broken marble treads on public stairs and problems with self-closing doors at the building entrance. The combined record of heating system problems, safety violations, and maintenance issues suggests ongoing challenges with building infrastructure and resident comfort, particularly during winter months.
