326 East 100th Street, Manhattan, NY 10029

The 92-unit, 6-story building at 326 East 100th Street in East Harlem, constructed in 1910, has experienced numerous maintenance and regulatory issues in recent years, particularly during 2024-2025. Most significantly, there are multiple active violations related to unauthorized construction work from mid-2024, including unpermitted installation of air conditioning units, unauthorized electrical and plumbing work, and concerns about a roof access opening in Apartment 6D.

The building's infrastructure systems have faced persistent challenges, with recurring complaints and violations regarding the elevator, boiler, and power systems throughout 2023-2025. Notable recent incidents include several heat and hot water outages in June 2025, though HPD confirmed restoration of services during inspections. The building's condition has raised consistent concerns about safety and habitability, with open violations for sewage and plumbing issues as of mid-2025, and a history of rodent activity requiring baiting interventions between 2024-2025.

The building's documented problems extend beyond immediate maintenance issues to include several environmental code violations, such as inadequate window A/C installations and plumbing discharge issues affecting the sidewalk, both of which carry significant financial penalties. Historical records show a pattern of housing maintenance code violations in Apartment 6C in late 2024, including issues with smoke and carbon monoxide detectors, pest infestations, plumbing problems, and interior maintenance concerns. While the building has had some violations resolved through appropriate certification, including problems with water supply and interior surfaces in 2024, many issues appear to persist or have recurred, suggesting ongoing challenges with building maintenance and regulation compliance.
