111 West 71st Street, Manhattan, NY 10023

111 West 71st Street is a 13-story, 113-unit residential building constructed in 1902, currently owned by Mark Jennings. The Upper West Side building has experienced recurring heating and hot water system issues throughout 2025, with multiple complaints filed between February and June 2025, including a recent building-wide complaint in June that was marked as an emergency. This pattern of heating system problems is noteworthy, as similar complaints were also documented in 2025, suggesting persistent infrastructure challenges.

The building has faced various health and safety concerns, including three indoor air quality complaints in April-May 2025 related to chemical vapors and odors, and an electrical wiring complaint in January 2025 where inspectors were unable to gain access for evaluation. The property has a documented history of bedbug infestations, with the most recent report from June 2025 indicating 6 affected units, though some units have been successfully treated. Previous infestations were recorded in 2024 (5 units), 2023 (1 unit), and 2021 (15 units), showing an ongoing challenge with pest management.

Other notable issues include a defunct elevator system (2024), concerns about falling debris (2024), and a boiler-related problem (2022), though inspections generally found no violations warranting penalties. The building's management has been cited for various violations over the years, including a 2021 issue regarding energy efficiency score display requirements and a 2018 complaint about unauthorized gas piping work in the fire pump room, though these violations were ultimately dismissed. While many complaints have been resolved through inspections and advisories, the recurring nature of heating system problems and periodic pest infestations suggest ongoing maintenance challenges within the building.
