The six-story, 18-unit New Law Tenement at 503 West 122nd Street in Morningside Heights, built in 1905 and currently owned by 122nd Street Investor LLC, has experienced numerous maintenance and compliance issues over the past several years. Most recently, in June 2025, there were multiple emergency service requests and violations related to flooring conditions, water leaks, and heating/hot water system problems affecting the entire building. The building has ongoing environmental concerns, including active violations for illegal duplex conversions with interior spiral staircases, structural issues with step cracks on the front facade's brick wall, and severe deterioration of a lintel above a fifth-floor window, all classified as active or newly issued environmental control board violations in 2024.

The property has a documented history of pest issues, with multiple bedbug infestation reports between 2019 and 2024, and persistent rodent activity as evidenced by multiple inspections showing rat activity throughout the building from 2023 to 2025. Housing Maintenance Code violations identified in late 2024 included problems with the intercom system, electrical outlet, smoke detector, and mold presence in Apartment 1 on the first story. The building's recent complaint history shows multiple service requests regarding unsanitary conditions, including reports of pests and mold in May 2025, though some complaints were found not to violate housing laws upon inspection.

The property has been the subject of several complaints regarding unauthorized alterations and illegal conversions between 2023 and 2025, with multiple inspections resulting in no violations being found, though there are active ECB violations presently regarding occupancy contrary to permits and structural modifications. The building's maintenance history shows regular permit issuances for exterior work between 2019 and 2021, indicating ongoing maintenance efforts by the ownership. While some recent complaints have been addressed through inspections and repairs, others remain open or have resulted in violations that the ownership is required to rectify within specified timeframes. The property has an established pattern of maintenance issues that appear to require ongoing attention and remediation, particularly regarding building systems and pest control.
