623A Willoughby Avenue, Brooklyn, NY 11206
623A Willoughby Avenue is a three-story, three-unit residential building located in Bedford-Stuyvesant, Brooklyn. Built in 1901 and currently owned by 623a Willoughby Ave LLC, this formerly Class A building has experienced several noteworthy maintenance issues over the past years.
Most prominently, there has been recurring non-compliance with the Housing Maintenance Code's bedbug reporting requirements, with open violations recorded in 2024 and previous violations in 2023 and 2021. While the building has submitted annual bedbug reports for 2021-2022 and 2020-2021 indicating zero infested units, the persistent violation notices suggest ongoing challenges with timely reporting requirements. The building has also faced significant rodent management challenges, particularly in 2024 and 2025, with initial inspections in May 2025 and November 2024 showing rat activity.
However, recent inspections indicate some improvement, with a passed compliance inspection in June 2025 and a previous compliance pass in December 2024. Between 2022 and 2023, the building underwent several bait treatments and showed passing results in multiple rodent inspections, though these measures indicate an ongoing need for pest management interventions. The building's maintenance history suggests attention to both bedbug and rodent issues, though compliance with reporting requirements and the pattern of rodent activity warrants attention to ongoing maintenance practices.
