678 St Nicholas Avenue, Manhattan, NY 10030

The 6-story, 35-unit building at 678 St Nicholas Avenue in Harlem, built in 1920, has experienced several recurring issues in recent years, with the most significant concerns centering around heat and hot water systems. The building has recorded multiple heat/hot water complaints in 2025 alone, including several duplicate complaints and one classified as an emergency. Other notable 2025 incidents include plumbing issues, indoor air quality concerns, and indications of internal smoke-free policy violations.

The property has also faced various infrastructural challenges, as evidenced by multiple Housing Maintenance Code Complaints in June 2025, including emergencies involving plumbing fixtures, and several non-emergency issues related to pest problems, painting/plastering needs, and electrical concerns. Reviewing historical data, the building has a pattern of maintenance issues, particularly regarding water supply and temperature control systems. Violation records show ongoing concerns with self-closing doors (notably in apartments 42, 56, and 64), plumbing fixtures in apartment D, and various maintenance concerns that span multiple years.

However, the building has consistently passed rodent inspections, with the most recent one in May 2025 showing no violations. Notably, there have been no reported incidents of bedbug infestations in the past five years, with all annual reports showing zero affected units. While the building has experienced numerous maintenance challenges, most violations appear to be addressed within reasonable timeframes, with many being classified as non-emergency or routine issues. Recent heat and hot water concerns, however, suggest continuing difficulties with building-wide systems.
