Augrented Insights Report for 305 Convent Avenue

305 Convent Avenue is a 6-story, 43-unit residential building constructed in 1920, currently owned by Mark Scharfman. The property has experienced recurring pest issues, with the most recent inspections in 2025 revealing ongoing rat activity, and recent violations for unsanitary pigeon conditions. Significant maintenance concerns have emerged in 2025, including multiple open complaints regarding plumbing issues (basin/sink) and an electric/gas range appliance problem.

The building suffered multiple heat and hot water emergencies between January and March 2025, though these complaints were closed when inspectors could not gain access to units for verification. The building has a documented history of elevator-related problems, with multiple complaints in early 2024 regarding single device operation and no alternate service. There are also serious structural and safety concerns, including a 2024 violation for unguarded shaftway components and a potentially unauthorized cellar apartment, with related fines totaling $2,530.

Multiple housing maintenance code violations were recorded in 2024-2025, including issues with radiators, window mechanisms, and kitchen cabinetry in apartments 34, 61, and 62. The building's history shows recurring problems with unauthorized units, with violations dating back to 2018 regarding excessive additional dwelling units. Bedbug reports indicate ongoing challenges, with infestations recorded in multiple units between 2021 and 2024, though all reported cases have been eradicated.
