111 6th Avenue, Brooklyn, NY 11217
As of July 2025, 111 6th Avenue in Park Slope, owned by Seth Weissman, is a three-story, former Class B building constructed in 1880 that has undergone conversion to a single-unit residence. The property has a consistent history of violations related to building maintenance and safety requirements, most notably with recurring open violations since 2021 regarding the failure to file annual bedbug reports, with the most recent citation issued in April 2024.
The building has also experienced multiple violations related to external low-pressure inspection filings between 2018 and 2023, though these were ultimately dismissed by February 2025. A significant maintenance issue was addressed in 2019, resulting in a $1,000 penalty for failing to file the 2017 boiler inspection report, while rodent inspections in 2018 identified rat activity, though subsequent inspections in 2018 and 2019 passed.
More recent developments include a building stability complaint in May 2025 that was investigated but found to warrant no violations. The property has undergone several permitted work projects between 2018 and 2020, including plumbing and electrical work, which were properly issued and completed according to records. While the building's maintenance history shows regular inspections and permit activity, the pattern of open violations, particularly regarding bedbug reporting requirements, suggests ongoing compliance challenges with housing maintenance code requirements.
