521 Grand Street, Brooklyn, NY 11211

521 Grand Street is a four-story, three-unit residential building located in Williamsburg, constructed in 1920 and currently owned by Ying Chiou Wang. The building has a documented history of bedbug-related compliance, with a significant violation recorded in April 2021 regarding the failure to file the required annual bedbug report with HPD, though this violation was subsequently closed.

Since that time, the property has consistently submitted bedbug reports showing no current or previous infestations in any of the units. The bedbug reports, covering the period from 2021 through 2025, indicate a total of four eradicated units in the 2019-2020 filing period, but no infestations or required eradications in subsequent years, suggesting successful management of this issue. The building's permit history reveals one issued permit from July 2018, classified as an "AL" type permit under job number 321642950, though the specific nature of this permit is not detailed in the available data.

The property appears to have maintained compliance with bedbug reporting requirements since the April 2021 violation, with regular filings submitted on schedule. The most recent bedbug report, filed in March 2025, continues to show no current or past infestations, incorporating data from the previous filing period of November 2023 to October 2024. The consistent pattern of reporting and the absence of recent violations suggest improved compliance with housing maintenance requirements over the past four years.
