Augrented Insights Report for 251 Nassau Avenue

As of July 2025, 251 Nassau Avenue in Greenpoint is a 4-story, 6-unit New Law Tenement building constructed in 1928 and currently owned by Norma Rap. The building has experienced several maintenance issues in recent months, with multiple uncompleted inspections by the Department of Housing Preservation and Development (HPD) in June 2025 related to heavy water leaks, electrical problems, and ceiling issues.

A concerning pattern of access issues for inspections has emerged, as evidenced by similar complaints throughout 2025 regarding heat and hot water problems, ceiling paint/plaster issues, and pest complaints, all of which were marked as "unable to inspect." A Department of Health and Mental Hygiene inspection in January 2025 found no violations regarding pigeon waste, and the most recent rodent inspection in February 2025 resulted in a passing grade. The building has a history of violations related to door hardware, with a B-class violation from December 2024 regarding a broken latch at the first-story vestibule door, and a C-class violation regarding defective self-closing doors, though these violations show as resolved. The property has maintained a clean bedbug record over the past several years, with no infestations reported in the official filings from 2021 through the present.

A Department of Buildings violation from June 2023 remains active regarding the failure to file a 2018 external low-pressure inspection. Multiple HPD complaints from January 2025 related to ceiling and wall paint/plaster conditions and unsanitary conditions due to pests were closed without inspection due to access issues, and similar problems with the building's intercom system were reported in June 2025. Despite these challenges, the building has shown efforts towards maintenance compliance, as evidenced by the recent e-filing permits issued in March 2022 for various work types.
