100 Throop Avenue, Brooklyn, NY 11206

The 140-unit, 8-story building at 100 Throop Avenue in Williamsburg, owned by Frank Lang, was constructed in 2022 and is currently experiencing notable infrastructure challenges. As of July 2025, there are persistent issues with heat and hot water systems, with multiple complaints filed in March, April, and May 2025, including one open complaint from May 2025 regarding hot water problems in individual apartments. The building has also faced ventilation system concerns and garbage storage issues, with violations issued by HPD in April and May 2025, respectively.

Other recent incidents include two emergency door-related complaints in June 2025, and a power outage in late March 2025. The building underwent its first bedbug reporting period from November 2023 to October 2024, showing no units were infested, eradicated, or re-infested. The property has a history of regulatory scrutiny, with several Department of Buildings complaints in early 2025 regarding after-hours work and unpermitted modifications, though inspections found no violations at the time.

A notable elevator-related issue was investigated in July 2025, resulting in an Oath Violation being served. The building was cited for not filing its energy benchmarking report by the deadline, though this violation was later dismissed after a successful challenge in June 2024. During its construction phase in 2023, there were multiple complaints regarding worker safety and site conditions, though inspections generally found no violations at the time. While the building is relatively new, these ongoing maintenance issues, particularly with essential services like heat and hot water, suggest potential challenges with building systems and management response.
