Augrented Insights Report for 818 Knickerbocker Avenue

818 Knickerbocker Avenue is a 6-unit, 3-story residential building located in Bushwick, constructed in 1912 under the New Law Tenement classification and currently owned by Elsie Ortiz. The property has experienced recurring heating and hot water issues, with multiple emergency complaints filed between October 2024 and November 2024 indicating building-wide problems that HPD was often unable to inspect due to access issues. As of November 2024, there are open violations relating to inadequate heat supply (Class C) and paint conditions in Apartment 2B from 2024 and 2023 respectively.

The building has a concerning history of maintenance issues, including unsanitary conditions documented in 2021 involving mold and pigeon waste, and several open violations from 2015 relating to Apartment 3A, including concerns about carbon monoxide detectors, smoke detectors, and various repair needs. The property has undergone regular bedbug reporting between 2019 and 2025, consistently reporting zero infested units, suggesting effective pest management. However, there have been multiple rodent-related inspections, with mixed results including confirmed rat activity in 2024, though the most recent inspection in April 2025 showed compliance.

The building has experienced several plumbing and maintenance issues over the years, with multiple work orders and violations closed or unresolved. A recent boiler complaint in November 2024 was inspected with no violations found at the time. The building's heating system has been a persistent problem, with numerous complaints filed by tenants throughout 2024. While the property has maintained a relatively clean record regarding bedbugs and passed recent rodent inspections, the recurring heating issues and various open violations suggest ongoing maintenance challenges.
