Augrented Insights Report for 639 4th Avenue

The 11-story, 44-unit residential building at 639 4th Avenue in Sunset Park, owned by Mufeed Siad and constructed in 2005, has experienced several significant maintenance and safety issues over the past few years. Most notably, there was a power outage in July 2023, followed by multiple concerning incidents in 2022, including uninvestigated complaints about fire escape safety, water leaks, and wall damage. During early 2022, three separate heat and hot water complaints were investigated and confirmed as resolved.

The building's facade and structural maintenance have been recurring problems, with multiple Department of Buildings violations between 2018-2024 related to exterior wall conditions, including missing metal flashing, rusty balcony supports, and various surface defects. The building has active violations as of 2023 for failing to submit required external low-pressure inspection reports from 2018-2021, and for not displaying the energy efficiency score and grade. Earlier violations included issues with the building's elevator system and compliance with bedbug reporting requirements.

While more recent bedbug inspections (2019-2024) show no infestations, there was an unaddressed violation for not filing the required bedbug report in 2022-2023. The building has passed rodent inspections, and several historical violations regarding the facade were resolved by 2021. Permits for external work were issued in 2021 and 2022, indicating some maintenance activity, though the pattern of violations suggests ongoing maintenance challenges.
