764 4th Avenue, Brooklyn, NY 11232

764 4th Avenue, a 10-story class B building constructed in 2009 and currently owned by Joseph Yunatanov, has experienced several recurring maintenance and safety issues over recent years. Most notably, there have been persistent problems with heat and hot water in 2025, with multiple emergency complaints filed through the Housing Preservation and Development (HPD) agency. The building has also faced ongoing rodent control challenges, with inspections in 2025 showing rat activity despite previous bait applications and compliance checks.

Elevator maintenance appears to be another significant concern, with multiple violations and complaints documented between 2022 and 2024, including out-of-service conditions and multiple device issues that resulted in Oath Violations. The building has undergone various safety inspections and faced multiple Environmental Control Board violations, particularly in late 2023 regarding emergency systems and maintenance issues. These included non-working emergency lights, problematic emergency exits, and excessive storage in the mechanical room. Noteworthy is the thorough documentation of bedbug reporting compliance, showing zero infestation cases across multiple reporting periods from 2022 to 2024.

While the building has faced multiple violations for not filing required reports (such as the FISP Cycle 9A Technical Report and energy benchmarking reports) between 2020 and 2022, these issues were ultimately dismissed or resolved. The property has maintained an active response to pest management, with rodent inspections showing varying results and the building's management apparently engaging with city agencies to address identified issues, as evidenced by the filing of annual bedbug reports showing no infestation cases. The building's current status as of July 2025 shows ongoing management of both pest control and heating issues, with inspections continuing to reveal rodent activity despite baiting efforts. The property has demonstrated some responsiveness to building code requirements, as seen in bedbug reporting compliance and periodic resolution of violations, though the frequency of certain issues suggests systematic maintenance challenges remain.
