Augrented Insights Report for 804 Knickerbocker Avenue

The three-story, four-unit tenement building at 804 Knickerbocker Avenue, owned by Hermann Kappel and built in 1910, has experienced several significant maintenance issues over the past few years. Most notably, there have been recurring problems with heat and hot water service, with multiple emergency complaints filed in February 2023 and February 2022, though these were reportedly resolved upon inspection. The building has also undergone multiple rodent control interventions in 2023, with inconsistent results showing rat activity in June 2023 and multiple bait applications throughout the spring and summer of that year.

More recent rodent inspections in 2024 and 2025 have passed, though an October 2023 inspection noted rat activity. The property has open violations as of 2024-2025, including the failure to file the required annual bedbug report and a missing heating system keyholder notice. Previous violations have included issues with fire escape access and a defective vestibule door.

The building's history shows regular bedbug reporting from 2020 to 2022 with no confirmed infestations during those periods. The owner has obtained necessary permits for work in 2019, and while some violations have been corrected and closed, including a 2023 violation regarding dropshoe repairs on fire escapes, others remain open as of the most recent inspections. The building's maintenance record indicates ongoing efforts to address various safety and comfort issues, though some problems have persisted or recurred over time.
