Augrented Insights

AI summary · updated June 2026

The three-story, six-unit tenement building at 180 Knickerbocker Avenue in Bushwick, owned by John Nyborg, has experienced several notable issues in recent years. Most concerning are multiple violations related to building safety inspections, including seven active violations for failure to file external low pressure inspections between 2018-2023, with the most recent violation issued in September 2024, and a 2019 violation for not filing the 2017 boiler inspection report. The building has also faced recurring heat and hot water issues, with a complaint in February 2021 that prompted HPD intervention, though tenants reported restoration of services.

The property has shown challenges with pest management, particularly regarding bedbug documentation, with open violations for failing to file annual bedbug reports from 2021 through 2024. While rodent inspections have improved recently, with passed results in 2024 and 2025, there were multiple incidents of rat activity reported throughout 2022 and 2023, including initial inspections in February, August, and September 2023 showing rat activity. Bait was applied in August 2022, and the building received multiple compliance inspections during this period. The building's age (constructed in 1931) and its classification as an "OLD LAW TENEMENT" are noteworthy, though these factors are typical for this category of New York City housing.
