Augrented Insights Report for 531 52nd Street

The 25-unit, 5-story residential building at 531 52nd Street in Sunset Park, owned by Zi Liang Liu and constructed in 2006, has experienced several recurring maintenance and safety issues in recent years. Most notably, there are persistent problems with the building's fire safety systems, including multiple violations regarding self-closing doors in the fire stairwells, with open violations recorded in September 2024 related to defective latchset assemblies in the second-floor and basement areas.

The building has also faced challenges with building access and security systems, as evidenced by multiple complaints in 2024 regarding the bell/buzzer/intercom system, though no violations were found during HPD inspections. Recent inspections have revealed several concerning conditions, including an open violation for mouse infestation in the cellar area (September 2024), and various safety-related violations including blocked or improperly functioning doors.

The building's maintenance history shows ongoing issues with egress systems, with multiple complaints about locked or blocked exits between 2023-2024, though inspections often found no violations or were unable to gain access. Additionally, the building has multiple active Department of Buildings (DOB) violations related to energy benchmarking requirements, with failure to file reports and display energy efficiency scores noted throughout 2023-2024. The property has maintained a clean record for bedbug infestations, with all recent reports showing zero affected units between 2020 and 2025.
