Augrented Insights Report for 300 Nassau Avenue

300 Nassau Avenue is a 6-unit, 3-story New Law Tenement building located in Greenpoint, built in 1931 and currently owned by Mordechai Katz. The property has experienced persistent maintenance issues over the past several years, with particular concerns about plumbing and sanitation. Most notably, from January to June 2024, there were multiple complaints regarding water leaks, sewer issues, and unsanitary sewage conditions, all of which HPD was unable to inspect due to access issues.

More recent complaints include a rodent sighting in October 2024 that resulted in violations needing follow-up inspections. The building has a documented history of rat activity, with the most recent inspections in late 2024 confirming ongoing infestations. The property has faced recurring heating and hot water system problems, with emergency complaints in November 2022 and November 2023, though these were reportedly resolved upon HPD investigation.

Additional maintenance concerns have included mold (July 2023), door/window issues (February 2023), and violations related to floor coverings and door maintenance in 2023. The building has active violations related to external low-pressure inspection filings from 2021-2022, and there have been multiple failed inspections and complaints regarding water retention and plumbing issues in 2023-2024. Despite these challenges, it's worth noting that the building's bedbug reporting has consistently shown zero infested units across multiple filing periods from 2018 to 2024.
