Augrented Insights Report for 9921 4th Avenue

The Harbour at Bay Ridge, a 52-unit condominium building constructed in 1987, has experienced several significant maintenance issues in recent years. A notable water leak complaint was filed in November 2022, classified as an emergency with heavy flow, though HPD was unable to gain access for inspection.

In April 2023, three Class C violations were documented regarding self-closing door issues at both the building entrance (1st story) and the north staircase (5th story), with one being closed following certification of correction. The building's elevator system has been a recurring concern, with multiple violations between 2019-2021 including inoperative devices, missing parts, and safety issues that resulted in ECB penalties totaling $3,750. Furthermore, there were failures to submit required Elevator Inspection Reports (EER) for multiple years (2019-2022), though these violations were ultimately dismissed upon submission.

The building's systems and safety features have been subject to various other violations, including multiple boiler-related issues documented in April 2018 involving safety valve discharge pipes and front boiler jacket concerns, with penalties totaling $1,550. While the building has maintained an active bedbug prevention program with no reported infestations from 2019-2024, recent permit activity shows continued maintenance work, including several permits related to elevator and safety system upgrades in 2023. The property's historical records indicate some pattern of deferred maintenance and compliance issues, particularly relating to elevator safety systems, self-closing doors, and boiler equipment, though many of these violations have been resolved through certification or dismissal following proper correction.
