947 St Marks Avenue, Brooklyn, NY 11213

947 St. Marks Avenue is a 16-unit, 4-story New Law tenement building located in Crown Heights, constructed in 1907 and currently owned by Nosson Lang. The property has experienced recurring issues with heating and hot water systems throughout 2025, with multiple complaints filed between February and April 2025, including recent complaints that remain open as of April 2025.

These heating system problems have been documented as impacting both individual apartments and the entire building. Additionally, the building has faced several maintenance issues, as evidenced by violations recorded in late 2024, including pest infestations, missing safety devices, and access problems affecting the boiler room. The building's inspection history reveals various compliance challenges, including a notable series of complaints about the intercom/buzzer system in early 2025, and a set of violations from late 2024 through early 2025 related to life-safety systems, such as missing smoke and carbon monoxide detectors in Apartment 1C.

Previous years show a mixed history of building maintenance, with some improvements noted in bedbug and rodent inspections, though there have been multiple failed rodent inspections between 2011 and 2023. The Department of Buildings has documented several violations requiring attention, including access issues to the boiler room in 2024 that resulted in an active ECB violation with a penalty of $1,250. The building's environmental history appears relatively stable, with consistent bedbug reporting showing no infested units since 2020-2021, though rodent inspections have shown variable results over the years.
