Augrented Insights Report for 238 Knickerbocker Avenue

238 Knickerbocker Avenue is a three-story, three-unit Old Law Tenement building constructed in 1931, currently owned by Yochanan Altberg. The building has experienced persistent rodent issues, with multiple 311 complaints and inspection records showing "Bait applied" results from May 2023 through April 2025, though recent inspections in 2024 and 2025 passed. A concerning pattern of food establishment violations was evident between 2022 and 2024, with multiple complaints regarding unsanitary conditions, including rodent and insect problems, spoiled food, and various sanitation issues, though these were generally addressed through administrative closures.

The building has several open violations as of 2024-2025, including failure to file annual bedbug reports, and requirements to post various safety notices in the public areas, such as carbon monoxide and smoke detector requirements, emergency procedures, and building registration information. The property has undergone some recent work, as evidenced by complaints in April 2023 regarding plumbing and electrical issues, though inspections did not warrant violations at that time. Notably, there was a recorded complaint about mold in December 2022, which was investigated by HPD but resulted in no violations.

The building currently has active Environmental Control Board violations regarding improper plumbing installation on the second floor (apartments 2R and 2L), though one related violation was resolved with no penalty. While there have been periodic issues with sanitation and maintenance, recent rodent inspections have passed consistently in 2024-2025, suggesting some improvement in pest control measures. The property's bedbug reporting history from 2019-2022 shows no recorded infestations during the required reporting periods.
