20 Willoughby Avenue, Brooklyn, NY 11205
20 Willoughby Avenue is a three-story, four-unit residential building located in Fort Greene, Brooklyn, constructed in 1865 and currently owned by Nicholas Cato. The property has experienced recurring pest management challenges, with three documented instances of rat activity in 2024-2025, most recently passing a compliance inspection in March 2025 after previous inspections in 2024 noted rat activity.
The building has also faced consistent requirements regarding bedbug reporting, receiving Housing Maintenance Code violations in 2021-2024 for failing to submit annual reports, though recent filings show no current infestations or eradicated units, suggesting improved compliance in this area. The Department of Health and Mental Hygiene (DOHMH) has found violations requiring follow-up inspections, particularly highlighted by a rat sighting in June 2024, though a standing water complaint from 2022 resulted in no violations being found. The building's history shows a pattern of addressing pest-related issues, with the property previously experiencing bedbug infestations in multiple units between 2019-2021, though these appear to have been successfully eradicated.
The most recent bedbug report filings from 2024 show no current infestations, which is a positive development. During the COVID-19 pandemic, the property was inspected in April 2020 with no violations found. The building's age and history of pest management challenges, particularly regarding rodents and bedbugs, indicate ongoing attention required for maintaining building conditions, though recent inspections suggest improvements in some areas of compliance.
