180 9th Avenue, Manhattan, NY 10011
180 9th Avenue is a four-story, seven-unit residential building in Chelsea, constructed in 1848 and currently owned by Harry Demott.
The building's maintenance history shows two notable violations: one from 2011 regarding inadequate entranceway lighting, which was eventually certified as corrected in August 2023, and another from 1986 concerning a defective window lintel, also certified as corrected in 2023. Fortunately, the property has demonstrated strong pest management practices, with seven consecutive annual bedbug reports from 2019 through 2025 showing zero infested units, no eradication efforts required, and no re-infestations.
The building has also maintained excellent conditions regarding rodent inspections, passing all ten inspections from 2017 through 2025, with the most recent inspection in July 2025 continuing this consistent record of compliance. The building's age and history of corrected violations suggest ongoing maintenance attention, while the lack of recent pest and rodent issues indicates effective building management in recent years.
