Augrented Insights Report for 480 Convent Avenue

480 Convent Avenue is a 5-story, 16-unit New Law tenement building constructed in 1906, currently owned by Gideon Stryker and located in the Hamilton Heights neighborhood. The building has experienced several significant maintenance and safety issues in recent years, most notably a recurring rodent problem, with inspections in 2025 showing rat activity and multiple service requests to the Department of Health and Mental Hygiene. Between 2023-2025, the property encountered various housing maintenance challenges, including plumbing issues, unsanitary conditions (notably mold), and safety concerns related to smoke and carbon monoxide detectors.

Multiple complaints in October 2024 regarding plumbing (bathtub/shower and water supply), door issues, and sanitary conditions required HPD inspections, though they were unable to complete inspections on certain occasions. The building has also faced several safety-related violations, particularly in 2023-2024, including problems with self-closing doors, fire escape encumbrances, and security-related issues. Notable violations from August 2023 included defective doors and a fire escape drop ladder problem, all of which have since been closed.

A heating violation from December 2022 in apartment 22 remains open as of the latest inspection records. The building's maintenance history shows relatively sporadic bedbug issues, with two units affected in 2021-2022 and documented eradication efforts, though recent reports (2022-2024) show no current infestations. The property experienced some stability concerns in early 2020, though these were resolved by September 2020 and no violations were found at that time.
