717 Flushing Avenue, Brooklyn, NY 11206
The three-story, four-unit tenement building at 717 Flushing Avenue in Williamsburg, owned by Frank Lang and built in 1931, has experienced significant maintenance issues over the past two years. Most notably, there have been recurring heat and hot water problems throughout the building, with three emergency complaints filed in 2025 (April 11 and 21) and one in 2024 (October 16), though HPD was unable to gain access for inspection in these cases.
The building has also faced multiple issues with pests, particularly in apartments 3F and 3S, with violations for roach and mouse infestations recorded in February 2022 (still open) and December 2023. Additional maintenance concerns documented in 2024 included problems with flooring and plaster in public areas, though these complaints were ultimately closed. The property has generated several code violations, including an open C-class violation from December 2023 regarding pest infestation in apartment 3S that requires attention, along with multiple B-class violations from February 2024 concerning encumbrances in public hallways and a C-class violation regarding defective roof bulkhead doors.
While there were three Department of Buildings complaints in December 2024 regarding unauthorized work and improper plumbing, inspections found no violations. Notably, the building has maintained a clean bedbug inspection record over the past five years, with no reported infestations between 2019 and 2025. The property's history shows some previous rodent issues, with failures in inspections from 2009 through 2013, but these do not appear to be recent concerns.
