687 5Th Avenue, Brooklyn, NY 11215

The 8-unit, 4-story building at 687 5th Avenue in Sunset Park, owned by David Halberstam, has experienced several notable events since 2021. Most significantly, there was a construction project in mid-2021 that generated multiple enforcement actions and violations.

The work, which appeared to involve extending the building from 3 to 5 stories, was conducted by JSB Works Inc. and led to two Environmental Control Board violations due to non-compliance with approved construction documents and poor housekeeping, resulting in fines of $625 each. The Department of Buildings issued three complaints related to construction safety compliance between June and September 2021, one of which resulted in a Stop Work Order that was later fully rescinded, while another led to an Oath Violation being served.

Multiple construction-related permits were issued in June 2021, showing the work was authorized despite the subsequent violations. On a positive note, the building has maintained a clean record regarding pest issues, with no reported bedbug infestations in the past three years (2022-2025) based on quarterly filings, and it passed a rodent inspection in December 2018. The property is a Class A building constructed in 1931, and despite the construction-related issues in 2021, there have been no significant complaints or violations recorded in the more recent timeframe from 2022 to July 2025, suggesting improved compliance with housing regulations.
