Augrented Insights Report for 521 Willoughby Avenue

521 Willoughby Avenue is a three-story, four-unit residential building constructed in 1931 in Bedford-Stuyvesant, currently owned by Chaim Eigner. The property has experienced recurring pest-related issues over the past several years, with the most recent HPD complaint about unsanitary conditions and pests filed in May 2023, though no violations were issued following the inspection. Additionally, the building has been subject to multiple Housing Maintenance Code violations regarding a failure to file annual bedbug reports between 2020 and 2024, and as of April 2024, there were several open violations requiring repairs and maintenance in public areas, including issues with ceilings, fire-rated materials, and paint conditions in the second-story public hall and cellar.

The building has undergone various inspections for rodent control, with initial inspections in 2023-2025 consistently passing, though there were two failures in 2021. The property has faced significant maintenance and safety concerns during construction work in 2022, with multiple Environmental Control Board violations issued to GS Interiors LLC for issues such as missing handrails, failure to maintain documents, inadequate protection for adjoining properties, and improper housekeeping during construction. These violations, totaling $7,875 in penalties, have been resolved.

Other notable incidents include complaints about building security in 2021, drainage issues, and debris management problems. While recent inspections for bedbugs and rodents have shown no active infestations or significant pest presence, the building's history of pest-related complaints and maintenance violations suggests persistent challenges in these areas. The most recent bedbug reporting period (2023-2024) shows no reported infestations, indicating potential improvement in pest management practices, while ongoing rodent inspections (2023-2025) have produced passing grades, suggesting some progress in pest control efforts.
