320 Columbus Avenue, Manhattan, NY 10023

320 Columbus Avenue is a 6-story, 20-unit Old Law Tenement building constructed in 1890, currently owned by Joseph Chadi. The building has faced numerous maintenance challenges in recent years, with the most pressing issues occurring in 2025. Recent concerns include ongoing rodent/insect/garbage issues documented through 311 complaints as of June 2025, and multiple complaints throughout 2025 related to indoor air quality concerns involving human feces.

The building has experienced repeated heat and hot water problems, evidenced by emergency complaints filed in April and May 2025, though inspectors were unable to gain access to verify the issues. The property has a history of building infrastructure problems, as seen in multiple housing maintenance code violations and complaints. In 2024, violations were recorded for inadequate smoke detector and carbon monoxide detector installations in Apartment 2A, and issues were documented with self-closing doors and evidence of a mouse infestation in that unit. The building's elevator system has faced scrutiny, with complaints about maintenance and access issues.

Environmental Control Board violations from 2024 indicate concerns about the building's exterior condition, with spalling of finish and structural issues noted at the arched entryway and decorative concrete trim. The property has undergone multiple rodent inspections between 2020 and 2024, with several instances requiring bait application, though recent inspections have passed. While the building has maintained compliance with bedbug reporting requirements, with no infested units reported in recent years, the persistent issues with heat, sanitation, and building maintenance raise ongoing concerns about habitability and resident comfort. The most recent active complaint as of 2025 involves sidewalk shed conditions, though previous violations related to illegal hotel rooms and transient use in 2024 suggest potential unauthorized occupancy concerns that were apparently resolved.
