Augrented Insights
AI summary · updated June 2026

720 Grand Street is a 4-story, 8-unit old law tenement building located in Williamsburg and owned by Sun Choi Tsang. The property, built in 1920, has experienced recurrent issues with heat and hot water service, with multiple building-wide outages reported through 311 calls in 2024-2025. This pattern of heating system failures spans from October 2024 through March 2025, with the most recent series of complaints occurring in March 2025 alone generating eight separate service requests. These heating issues appear to have been temporarily resolved after HPD inspections, though evidence suggests they may not have been permanently fixed.

The building has also faced several maintenance challenges, particularly regarding door security and functionality. Inspections in 2023-2024 identified multiple violations related to defective doors and locks at the building entrance and vestibule, including a missing self-closing mechanism and faulty latches, though these violations were subsequently certified as corrected. The property has shown a concerning pattern of rodent activity, with inspections throughout 2022-2024 consistently indicating the presence of rats. Additionally, there were reports of construction-related concerns in 2024-2025, including two instances of building shaking/vibrating, though inspections did not warrant violations at that time.
