Augrented Insights Report for 6309 23rd Avenue

At 6309 23rd Avenue in Borough Park, this 6-story, 64-unit New Law Tenement building from 1931 has experienced several concerning issues in recent years. Most notably, in January 2025, multiple urgent safety concerns were reported, including problems with carbon monoxide detectors, smoke detectors, window guards, and pest infestations. These complaints required HPD intervention, though inspections could not be completed, leaving questions about their current status.

The building has a documented history of maintenance challenges, including a water leak issue in mid-2024 that led to violations, and a February 2024 complaint about lack of heat/hot water that could not be inspected. Apartment 3E experienced multiple issues in mid-2024, including the need for mold remediation, water leak repairs, and various required repairs to doors and ceilings, resulting in both open and closed violations. The property has faced recurring elevator service issues, with multiple complaints about single-device operation and lack of alternate service between 2018 and 2023, though most were resolved through compliance actions.

Safety violations have been documented regarding door security and fire escape conditions. The building has been free of bedbug infestations in its past three reporting periods (2021-2024), with only one occurrence (4 units) recorded in 2019-2020. Environmental Control Board violations were issued for elevator maintenance and building safety concerns, though most have been resolved. While the building's management (Peter Rebenwurzel) has addressed many past violations, including elevator repair issues with a recent penalty, the frequency of recent complaints and the nature of some unresolved safety concerns merit attention to building maintenance practices and inspection access challenges.
