The 8-unit, 4-story Old Law Tenement building at 483 Warren Street in Gowanus, currently owned by Moshe Singer, has experienced several notable maintenance issues in recent years, most significantly in the area of heating systems. In December 2024, an emergency heat/hot water complaint was filed, though inspectors were unable to gain access to the apartment for verification. The building has also faced ongoing pest-related challenges, with multiple unsanitary condition complaints regarding pests filed throughout 2024, and garbage/recycling storage issues, particularly notable in July 2024 when access for inspection was again not granted.
The property has several open violations from 2020 and 2024 that relate to safety concerns, including improper maintenance of fire escape egress at the 3rd and 4th stories (flower pots and air conditioners obstructing egress) and requirements for proper signage regarding gas leak procedures and building registration. Historical inspection records from 2020 show a cluster of various maintenance issues, including concerns with door/window frames, ceilings, and floors, though most of these were addressed and closed. Recent rodent inspections in 2025 indicated the presence of rat activity earlier in the year, with baiting efforts conducted through spring 2025, though a compliance inspection in June 2025 showed passing results. The building's bedbug reporting records from 2019 through 2024 show no infestations or infestations requiring eradication, suggesting good management in this area, though multiple pest-related complaints in 2024 indicate some ongoing challenges.
