4723 4th Avenue, Brooklyn, NY 11220
The three-story, four-unit old law tenement building at 4723 4th Avenue in Sunset Park, owned by Carmen Nunez and constructed in 1931, has experienced several notable issues over the past several years. Most concerning is the ongoing failure to comply with the Housing Maintenance Code's bedbug report filing requirement, with four separate violations recorded between 2021-2024 (April 2023 being the most recent) remaining open as of now.
The building has also faced rodent-related challenges, with two rat sighting complaints recorded in late 2022 (October and December) which led to inspections by the Department of Health and Mental Hygiene. While the October inspection passed with minor violations and was later closed, the December complaint was closed due to it being a duplicate of an earlier complaint.
The property underwent three rodent inspections between 2014-2022, with the most recent initial inspection in October 2022 being passed, though a May 2014 initial inspection had failed for "Other Reasons." In addition to these issues, there was a complaint regarding an illegal conversion in July 2018, though the Department of Buildings inspector was unable to gain access during the second final attempt in August 2018, and this complaint was subsequently closed. The building's maintenance history indicates recurring challenges with both pest management (as evidenced by the multiple bedbug report violations) and rodent control, though the most recent rodent inspections suggest some improvement in that area. The pattern of open violations related to bedbug reporting requirements over multiple years may indicate ongoing compliance challenges by the property management.
