211 Warren Street, Brooklyn, NY 11201

The four-story, five-unit Old Law Tenement building at 211 Warren Street in Cobble Hill, owned by Marne Lenox, has experienced several recurring issues over recent years. Notably, there have been consistent violations related to bedbug reporting from 2021 through 2024, though the most recent 2025 bedbug report indicates no current infestations, with zero infested or re-infested units.

Between 2019 and 2024, the building accumulated multiple Housing Maintenance Code violations, many of which remain open, including failures to properly post required safety notices concerning smoke detector requirements, heating system access, and gas leak procedures in the first-story public hall. In 2019, violations were cited for not maintaining proper signage regarding the building's registration number and housing information guide. Prior to these issues, the building had three complaints regarding illegal after-hours work in 2018, though inspections found no violations at those times.

The most recent inspection of rodent conditions in March 2023 resulted in a passing grade. Several permits were issued between 2018 and 2019, though the specific nature of these permitted works is not detailed in the available data. The building's documented history suggests ongoing challenges with regulatory compliance and safety signage requirements, though recent bedbug reporting indicates successful eradication of that particular issue.
