5210 4th Avenue, Brooklyn, NY 11220

This three-story, two-family house at 5210 4th Avenue in Sunset Park, owned by Zvi Lann, has a complex history dating back to its 1920 construction. The most recent significant issue came to light in late 2022 with a mold complaint that was investigated by the Department of Housing Preservation and Development (HPD) but resulted in closed inspection due to lack of access.

The building has an extensive record of maintenance violations, particularly affecting the third-story apartment (Apt 3) in 2007, when multiple issues were documented including problems with the flushing apparatus, gas supply, water supply pipes, and hot water provision - all of which were later certified as resolved in 2022. Two important regulatory matters were handled in 2004, when violations were issued regarding illegal multiple dwelling use and unauthorized living spaces in the cellar, though these were also certified as resolved.

More recent investigations have focused on potential illegal conversion issues, with a complaint filed in late 2022 and an inspection in April 2023 where the inspector was unable to gain access. While there have been three bedbug reports between 2020-2022, all showing zero infested units, there were two rodent inspection failures in early 2018, suggesting some ongoing pest management challenges. The building's records indicate various maintenance issues over the years, with a mix of resolved and ongoing concerns related to plumbing, heating, and pest control.
