Augrented Insights Report for 6811 7th Avenue

The two-story, 3-unit residential building at 6811 7th Avenue in Dyker Heights, owned by Saiying Liu, has experienced significant regulatory attention since 2023. Most notably, in June 2023, the property received multiple environmental control board violations related to illegal occupancy, with records showing unauthorized conversion from its legally approved Class A multiple dwelling status to nine furnished transient rooms (hostel) accommodations.

These violations resulted in substantial penalties, including $15,000 for two illegal occupancy citations, $1,250 for failure to maintain a proper fire safety system, and additional fines for various safety code violations. The Department of Buildings also initiated investigations into construction work and illegal hotel room usage in mid-2023, though these complaints were ultimately closed without violations being found.

The building's maintenance history reveals consistent reminders to file annual bedbug reports, with violations recorded in 2021 through 2024 related to this requirement, though no actual bedbug infestations or eradication efforts have been documented in any of the reports. The most recent bedbug report from May 2024 indicates that no units were infested during the previous reporting period (November 2022 - October 2023).
