434 79th Street, Brooklyn, NY 11209
The three-story, 16-unit apartment building at 434 79th Street in Bay Ridge, owned by Jon Diacomanolis, has experienced several maintenance issues over the past few years, with the most significant problems emerging in 2021. A March 2021 inspection of Apartment 1B revealed multiple violations, including water damage, mold, and issues with safety devices, with open violations currently remaining for improper repairs related to water leaks, damaged plaster surfaces, and missing smoke/carbon monoxide detectors.
The building has experienced plumbing and water leak issues in 2020, including heavy flow problems and sink issues that necessitated HPD intervention. Earlier, in 2019, there were concerns about rodent activity, with multiple complaints registered with the Department of Health and Mental Hygiene, though rodent inspections that year ultimately passed.
More recent records indicate that the building has maintained a clean bill of health regarding bedbugs, with all eight annual reports from 2018 to 2025 showing zero infested or eradicated units. The building's current condition appears stabilized in terms of pest control, though the outstanding violations from 2021 related to safety devices and water-related issues suggest there are still some unresolved maintenance matters that affect resident comfort and safety. The property, built in 1942, has not shown any significant new violations or maintenance issues since 2021, though the age of the building means regular maintenance and upkeep are always a consideration for residents.
