This 4-story, 8-unit Old Law Tenement building in Sunset Park, owned by Jennifer Lau and constructed in 1910, has experienced several recurring maintenance issues in recent years. Most notably, there was a heat and hot water outage affecting the entire building in November 2024, though service was reportedly restored shortly after the complaint was filed. The building has faced persistent flooring problems, with multiple complaints recorded between 2023 and 2024, including emergency situations in both August and October 2024.

There were also significant unsanitary conditions reported in August 2023, specifically mold issues, for which violations were issued and later certified as addressed. The property has undergone various repairs and improvements, as evidenced by several Housing Maintenance Code violations and subsequent certification of correction. These included window repairs in Apartment 3C (October 2024), and multiple issues in Apartment 1A (April 2024) involving carbon monoxide detector replacement, floor tile repair, and various other maintenance matters.

The building's management has maintained an active response to pest control, with annual bedbug reports from 2019 through 2024 showing no reported infestations. Two construction-related complaints were filed in 2021, though inspectors found no violations upon investigation. While the building has experienced multiple maintenance issues, particularly regarding heating and flooring, there appears to be a pattern of prompt responsiveness to complaints and resolution of violations, with most issues being addressed within weeks of inspection.
