Augrented Insights Report for 771 4th Avenue

771 4th Avenue is a 4-story, 8-unit residential building in Sunset Park, built in 1920 and currently owned by David Knoll. The property has experienced persistent heating system issues over recent years, with multiple HPD complaints regarding heat and hot water problems in both 2022 and 2023, continuing into 2025, with at least six separate emergency complaints in 2023-2025 documenting either lack of access for inspection or documented violations.

The building has maintained a regular bedbug reporting record from 2021-2025 showing no infestations during the past four reporting periods, and recent rodent inspections in 2021 showed mixed results with one "Rat Activity" finding and one "Passed" inspection within the same year. The building has several open and closed housing maintenance violations from 2020 and 2023, primarily related to safety and maintenance issues in the first-story public areas. These violations include problems with self-closing doors at the building entrance (currently marked as Class C open violation from 2023), along with various issues including broken ceramic tiles, fire retardant material problems, and requirements for the proper posting of inspection certificates.

While some violations from 2020 and 2023 have been certified as corrected, including issues with door/window conditions and certain maintenance matters, there remains an open violation from 2023 regarding the self-closing doors. The property also received an annual bedbug report in 2025 showing zero infested units, and the last documented repairs were made to various public area maintenance issues in spring 2023, with violation certification dates between April and June 2023 showing active management of some maintenance concerns. This 1920 building has had ongoing heating system challenges from 2022 through 2025, with multiple complaints and some violations issued; the property appears to have addressed many building code violations as of 2023, with a focus on maintaining compliance with bedbug reporting requirements showing zero infestations during the past several years.
