Augrented Insights Report for 11 Maple Street

The 6-story, 55-unit New Law Tenement at 11 Maple Street in Prospect-Lefferts Gardens, owned by Jacob Rosenberg and constructed in 1926, has experienced significant maintenance challenges in recent years. Most notably, there have been recurring heat and hot water issues, with multiple emergency complaints between January and June 2025, suggesting persistent problems with the building's heating infrastructure. The building has faced documented rodent-related concerns, with multiple rat sightings reported between February 2025 and July 2025, though recent inspections in July 2025 passed.

Apartment B8 has been a focus of multiple open violations from 2024-2025, including issues with pest infestations (mice and roaches), missing kitchen fixtures, and a lack of proper safety devices (smoke and carbon monoxide detectors). Other documented issues include window frame problems, water leaks, and mold concerns, though many of these complaints were closed without violations being issued. The building's history also shows a pattern of complaints regarding illegal conversions, elevator service issues, and work being performed without permits, with several inspection attempts being unable to gain access.

Notable regulatory matters include a 2018 violation for unpermitted work involving demolition and electrical work on the 6th floor, though this was resolved with a $1,280 penalty. The property has maintained regular bedbug reporting compliance, with no infestations recorded in the past five years. While some building systems have shown improvement, as indicated by passing recent rodent inspections, the frequency of heating-related complaints and persistent violations in specific apartments suggest ongoing maintenance challenges.
