706 Lefferts Avenue is a 49-unit, 6-story "New Law Tenement" building located in East Flatbush, Brooklyn, constructed in 1928 and currently owned by Marc Barron. The building has experienced numerous maintenance issues throughout 2025, with the most significant being persistent mold problems, multiple unsanitary conditions, and infrastructure concerns including heating systems and electrical systems. Between February and June 2025, there were several 311 service requests that required HPD inspections, including complaints about water leaks, lighting problems, ceiling issues, and door problems, several of which resulted in violations being issued.
The building has a documented history of elevator and structural concerns, particularly between 2021-2024, with multiple complaints about elevator service and building shaking/vibration issues. Violations related to the elevator's fire safety equipment and structural concerns about the sidewalk shed were noted in 2024, with associated fines. In terms of pest control, while there were incidents of bedbugs reported between 2018-2021, recent filings from 2022-2024 show no current infestations.
The building's rodent inspections have shown mixed results, with some passing inspections but also indicating rat activity in late 2024. A significant cluster of violations was documented in 2024 for apartment 4C, including issues with electrical systems, plumbing, plastered surfaces, and pest control, though most of these violations were certified as corrected by late 2024. The building's maintenance history shows ongoing challenges with basic services and infrastructure, requiring regular intervention from city agencies.
