Augrented Insights Report for 315 West 121st Street

This five-story, 20-unit Old Law Tenement building located at 315 West 121st Street in Harlem, owned by Michael Johnson, has experienced numerous maintenance issues over the past two years. Most concerning are the ongoing water-related problems, with multiple complaints about leaks and damp spots documented in 2025, including an open slow leak complaint from April 2025 and a similar non-emergency issue from January 2025.

The building has also faced significant heating and hot water challenges, with Class C violations for inadequate hot water service in apartments 6 and 10 noted in a November 2024 inspection, along with multiple heat/hot water-related complaints in December 2024 that required HPD intervention. Additional maintenance concerns include recurring rodent activity, with multiple inspections showing rat activity and bait applications throughout 2024 and 2025, suggesting an ongoing pest management challenge.

The building has also experienced various infrastructure issues, including problems with door and window maintenance, ceiling paint/plaster conditions, and an emergency mold situation in February 2025. Several violations remain open as of 2025, including access issues for HPD inspections and concerns about building system access in the basement. While the building has documented bedbug-free status in recent years, the persistent pattern of water issues, heating system problems, and rodent activity suggests ongoing maintenance challenges affecting resident quality of life.
