Augrented Insights Report for 326 21st Street

The four-story, eight-unit Old Law Tenement building at 326 21st Street in Sunset Park, owned by Ben Herskowitz and constructed in 1931, has experienced several recurring maintenance issues in recent years. Most notably, in May 2025, the building faced both mold and heat/hot water problems, with the former being classified as an unsanitary condition and the inspection attempt by HPD being unsuccessful. Previous complaints include pest issues in March 2023, multiple maintenance problems in 2022 (including radiator, floor, electric, and water leak issues), and various unit-specific and common area concerns in 2021 regarding appliances and systems.

The building has maintained a record of filing annual bedbug reports showing zero infested units from 2021 through 2024, and while rodent activity was documented in early 2019, subsequent bait applications were performed. The property has undergone several significant structural and safety-related incidents, including emergency violations regarding carbon monoxide and smoke detectors in 2020, along with a 2021 violation for the building's entrance doors. Multiple construction-related complaints were filed between 2018-2021, including instances of work without permits and concerns about building stability, though inspections generally found no violations at the time.

The building has also demonstrated compliance with bedbug reporting requirements since 2021, with no reported infestations. Several environmental control board violations were issued regarding expired permits and construction equipment, though these have been resolved. Recent maintenance records suggest ongoing challenges with building systems and maintenance access for inspections, as evidenced by multiple instances where HPD was unable to complete inspections for reported issues.
