424 Grand Concourse, Bronx, NY 10451

424 Grand Concourse, a 5-story, 28-unit New Law Tenement building in Mott Haven built in 1905, has experienced numerous maintenance issues over the past two years, particularly concerning plumbing and heating systems. Most recently, in January 2025, there were complaints about heating and hot water issues affecting individual apartments and radiators, though these were reportedly corrected. Throughout 2024-2025, the building faced multiple plumbing problems, including issues with bathtubs, showers, and toilets, with some complaints indicating violations were issued upon inspection.

The building has also contended with significant sanitation challenges, including unsanitary conditions involving mold (particularly in Apartment 51), pests, and a rodent infestation, with several relevant violations recorded in July 2024. Notably, there are open mold violations affecting Apartment 51 as of August 2024. The building's heating systems have been a recurring issue, with complaints about both apartment-specific and entire building failures.

The property has documented multiple rodent activity instances, with inspections in 2023 showing rat activity and bait application responses. While the building has a history of bedbug reports, recent filings (2023-2024) show no active infestations, suggesting successful eradication of previous outbreaks. The building's maintenance history shows a pattern of both emergency and non-emergency complaints, with many requiring multiple follow-ups for resolution. While some violations have been certified as corrected (such as those from April-June 2024 involving various plumbing issues, and certain pest and mold violations), the pattern of recurring issues suggests ongoing maintenance challenges.
