85 Clarkson Avenue is a 6-story, 71-unit residential building in Prospect-Lefferts Gardens, constructed in 1931 and currently owned by Marc Barron. The building has recently experienced several concerning maintenance issues, particularly regarding heat and hot water systems in April 2025, when multiple complaints were filed by residents though heat and hot water were reportedly restored upon inspection. More recently, in May 2025, there was an attempted HPD inspection regarding door issues that could not be completed.
The building's history shows recurring problems with both elevator and door/window maintenance, as evidenced by multiple complaints and violations over the years. Particularly notable are the repeated complaints about multiple elevator devices, with the most recent active complaint recorded in April 2025, and persistent door issues, including violations related to door frames and self-closing mechanisms. The property has undergone several inspections and addressing of violations between late 2024 and early 2025, including notable issues in apartment 6H regarding smoke and carbon monoxide detectors, and an infestation problem.
Earlier violations from 2024-2025 indicate various maintenance concerns, including an outstanding bathroom flushing apparatus issue in apartment 3D. The building's rodent inspections suggest ongoing challenges with pest control, with multiple inspections in 2023-2024 showing "Rat Activity" and bait applications. Despite these issues, there have been no reported bedbug infestations in the past three years, indicating one positive aspect of the building's maintenance history.
