925 Union Street, Brooklyn, NY 11215
The six-story New Law Tenement building at 925 Union Street in Park Slope, owned by Gregory Cohen, was constructed in 1920 and contains 52 residential units. The building has experienced several maintenance and compliance issues over recent years, with 2020 proving to be a particularly problematic year. During that year, multiple housing maintenance code complaints were filed regarding unsanitary conditions including mold, pests, and plumbing issues, with most being closed by December 2021.
The building has faced ongoing challenges with safety compliance, particularly regarding required notices and device installations - as evidenced by multiple open violations from December 2020 requiring proper posting of bedbug reporting procedures, smoke detector requirements, carbon monoxide detector requirements, gas leak procedures, and electrical outlet safety. Two bedbug report filings in 2023-2024 and 2024-2025 confirm no infestations during those periods. More recent history shows some positive developments, including the closure of a significant number of environmental control board violations related to boiler maintenance from 2018 and the resolution of multiple Department of Buildings violations regarding annual filings and reporting requirements.
The building passed a rodent inspection in 2018, and while a smoking violation was recorded and closed in 2024, there have been no major safety incidents reported in recent years. The most recent bedbug filing in 2025 shows zero infested units, suggesting effective pest management. Despite these improvements, as of the latest data in 2024, there remain some open violations from 2020-2021 period regarding required safety postings and building notices that have not been fully resolved, though the building has made progress in recent years to address various maintenance and compliance issues.
