The 32-unit, 4-story New Law Tenement at 5413 7th Avenue in Sunset Park, owned by Baozhen Chen, has experienced several recurring maintenance issues in recent years. Most notably, there have been multiple heating and hot water problems affecting the entire building, with seven documented complaints between January and April 2025, despite some inspections confirming restoration of services. The building has also faced pest control challenges, with current violations as of October 2024 indicating active mouse and roach infestations in apartment 5D.

Recent inspections revealed multiple safety concerns, including broken window guards, and ongoing issues with building systems such as intermittent power outages and rodent activity, with the most recent rodent-related complaint in June 2025 despite recent inspections showing rat activity. The property has an active violation regarding failure to file the 2022 External Low-Pressure Inspection as of April 2023. Previous maintenance history shows a pattern of emergency heat/hot water complaints, mold issues, and problems with building security systems.

The building underwent a Department of Buildings inspection in October 2024, revealing several violations requiring attention, including defective smoke and carbon monoxide detectors in apartment 5D, and issues with fire-retardant materials in the public areas. Historical data shows past concerns with illegal conversions and unauthorized hotel rooms in 2022, though access was denied during inspections of these complaints. A 2019 inspection revealed issues with the boiler system that required attention, including a missing support for the flue and other safety concerns. The building has maintained a relatively low incidence of bedbugs, with only one reported case in 2025 that was reportedly eradicated.
