300 South 3rd Street, Brooklyn, NY 11211
The 6-story, 24-unit New Law Tenement building at 300 South 3rd Street in Williamsburg, owned by 300 South Realty Corp and constructed in 1913, has experienced several significant maintenance and regulatory issues in recent years. Most concerning is a pattern of water-related problems, including recent complaints about mold (May 2025) and historical issues documented in 2023-2024 in Apartment 3B, where violations were noted for mold, water leaks, and various other maintenance issues including electrical wiring problems, broken fixtures, and peeling paint.
The building has also faced persistent heating and hot water issues, with multiple emergency complaints in February 2025 regarding inadequate heat throughout the building. The property has a documented history of regulatory violations, including a serious incident in 2019 involving illegal short-term rentals that resulted in multiple citations related to safety systems and penalties totaling $2,306, though these were later resolved.
Recent inspections have shown no current bedbug problems, and rodent inspections have had mixed results, with the most recent inspection in December 2023 passing. Several recent complaints in 2025 were closed without violations being found, including issues with windows, water leaks, and garbage storage. The building's most recent 311 service request, from May 2025, regarding smoking in a non-smoking area, remains in progress as of July 2025.
