426A 7th Avenue, Brooklyn, NY 11215

426A 7th Avenue is a four-story, four-unit residential building located in the South Slope neighborhood. Built in 1887, this old law tenement currently owned by Ronald Grossberg has experienced several notable maintenance and compliance events over recent years.

In February 2018, the building received multiple violations related to its boiler system in Unit 7, including issues with a manual reset water cutoff, corroded return, exposed wiring, and an air conditioning problem, though these violations were later resolved with no penalties assessed. A subsequent violation recorded in October 2018 was dismissed by February 2019.

The building's maintenance record shows some ongoing attention to infrastructure, with several permits issued in late 2018 for plumbing, alteration, and exterior work (specifically windows), suggesting building system upgrades or repairs. Notably, the building has demonstrated excellent pest management, with eight consecutive bedbug reports from 2019 through 2025 showing zero incidents of infestation, eradication, or re-infestation across all units. The most recent bedbug report filed in May 2025 covers the period from November 2023 to October 2024, again confirming no infestations in any of the four units, continuing a consistent pattern of effective pest control over the past several years.
