1120 5th Avenue, Manhattan, NY 10128

1120 Fifth Avenue is a 15-story, 45-unit residential building constructed in 1925 in New York City's Upper East Side neighborhood, currently owned by James Gallagher. The building has experienced several significant maintenance and safety issues over the past few years, with the most recent incident occurring in June 2025 involving illegal or defective gas hook-up/piping, for which an Oath Violation was served. A serious construction incident occurred in November 2021 when welding operations on the 13th floor resulted in a window fire, leading to two Environmental Control Board violations related to construction safety and accident notification, though these were eventually resolved.

The building was found to have unsafe facade conditions in February 2022 (per LL11/98), though records show subsequent inspections may have resolved this issue. The property has had multiple inspection and compliance requirements to manage, including the need to file a benchmarking report of energy use (though this violation was dismissed), and multiple references to "swarm conditions" that were eventually dismissed as well. Notably, the building has maintained a clean record regarding bedbug infestations, with no reported cases in the past eight reporting periods from 2018 to 2024.

Regular rodent inspections between 2010 and 2024 have consistently passed. The building has undergone several permitted construction activities between 2019 and 2021, primarily related to emergency work, suggesting ongoing maintenance and repair operations have been conducted during this period. Recent inspections, including one in late 2024, indicate improved compliance with various safety and maintenance requirements, though the 2025 gas-related violation suggests some ongoing infrastructure concerns.
