Augrented Insights Report for 100 Dean Street

100 Dean Street is a three-story, four-unit residential building located in Boerum Hill, Brooklyn, and constructed in 1861, currently owned by Ai Fang Loy He. The property has a documented history of bedbug reporting requirements under the Housing Maintenance Code (HMC), with violations noted annually from 2021 through 2024 for failure to file the required bedbug reports, though more recent filings indicate compliance as no infested units were reported in the 2023-2024 and 2024-2025 reporting periods.

The building's bedbug report history shows an interesting pattern: during the 2019-2020 reporting period, there were four infested units that required eradication, but subsequent years from 2020 onwards have shown no reported infestations. Additionally, the building has undergone rodent inspections, with a rat activity report recorded in January 2011, though it subsequently passed a compliance inspection in May 2011.

While the building is relatively old and has had its share of maintenance violations, the most recent bedbug reports suggest successful management of that particular issue, with no infestations reported in the past two years. The property has seen improvements in regulatory compliance over the years, particularly regarding bedbug reporting requirements, with the last documented violation occurring in 2024.
