321 East 78th Street, Manhattan, NY 10075

321 East 78th Street is a 4-story, 16-unit residential building constructed in 1900, currently owned by KC3-319-321 East 78th Street LLC and classified as an Old Law Tenement. The building has experienced recurring heating and plumbing issues, with multiple emergency complaints regarding heat and hot water systems in December 2024, and several plumbing-related issues between 2020-2021 including water supply problems and bathtub/shower concerns. The property has undergone regular rodent inspections, all of which have passed, with the most recent inspections occurring in 2025, 2023, and 2019.

A notable mechanical issue was recorded in 2021 regarding a defective boiler system, which resulted in an Oath Violation being served. The building has maintained a zero-infestation record for bedbugs in the past five reporting periods (2019-2024), though violations were issued in 2020-2021 for improper cabinet and sink maintenance in apartment 3A, which have since been certified as corrected. Recent events include the closure of two work without permit complaints in late 2023, though inspectors were unable to gain access during their investigations.

The Department of Buildings currently has an active ECB violation from June 2021 related to multiple mechanical deficiencies including a rotted flue pipe and gas line issues, with an associated penalty of $625. The building's management has generally responded to complaints as they arise, with multiple instances of HPD closing complaints after confirming corrections were made, though some complaints were marked as duplicates or related to existing issues requiring verification. The property has consistently passed regular rodent inspections over the years, with the most recent inspections occurring in 2025, 2023, and 2019 showing no violations.
