Augrented Insights Report for 643 Southern Boulevard

643 Southern Boulevard is a 6-story, 46-unit New Law Tenement building constructed in 1925 and currently owned by David Tennenbaum. The property has experienced several significant maintenance issues in 2025, with multiple Housing Maintenance Code violations and complaints in May alone, including problems with flooring, plumbing, doors/windows, and the presence of mold. Unit 2F has documented violations from a December 2024 inspection, including issues with mold, water leaks, and damaged ceilings, walls, and floors, while Unit 5B has ongoing roof leak problems noted in November 2024.

The building faced an illegal conversion complaint in May 2023 related to an unauthorized metal shed in the courtyard, for which a penalty was imposed. The building's maintenance history shows recurring issues with appliances, water supply, flooring, and unsanitary conditions. Most recently, emergency violations were issued in May 2025 for plumbing (water supply) and paint/plaster (ceiling) issues.

A notable pattern of water-related problems is evident, with multiple plumbing complaints and housing violations regarding leaks and water damage in both Units 2F and 5B. While the building has shown consistent compliance with bedbug reporting requirements, maintaining a record of zero infested units since at least 2021, rodent inspections present a mixed picture, with recent inspections in 2023 showing passing results, though there were failures noted in 2015-2018 which required bait applications due to rat activity. The presence of active violations and persistent maintenance issues, particularly regarding water damage and mold, suggests ongoing challenges with building upkeep.
