733 Prospect Avenue, Bronx, NY 10455

733 Prospect Avenue is a 5-story, 17-unit New Law Tenement building located in the Longwood neighborhood, owned by Arsen Yakubov and built in 1906. The building has experienced persistent maintenance issues in recent years, with multiple complaints and violations recorded throughout 2024 and 2025. Most notably, there are open Class C violations from December 2024 regarding inadequate heat and hot water in Apartment 12, along with heating system access issues.

The property has also faced recurring problems with mold, flooring, and sanitation, with multiple complaints about these issues between March and May 2025, though inspections often resulted in no violations being issued. A significant concern is an active Environmental Control Board violation from 2022 regarding unauthorized construction work in Apartment 3, with a penalty of $6,250 still due. The building's history includes multiple Department of Buildings complaints about illegal conversions between 2019 and 2022, and recent inspections in late 2023 recorded persistent rat activity, although bait was applied during inspections in late 2024.

The property has several active VI-DOB violations from 2023 for failure to file external low-pressure inspections, and there are open violations from 2024-2025 regarding various maintenance issues. While recent housing maintenance code complaints have been closed, many resulted in inspections that were either inconclusive or showed no violations, suggesting ongoing communication challenges between tenants and authorities. The building's maintenance history demonstrates a pattern of recurring issues, particularly with heating, water systems, and structural elements, although not all complaints result in official violations being recorded.
