100 Diamond Street, Brooklyn, NY 11222

100 Diamond Street is a 4-story, 8-unit New Law Tenement building located in Greenpoint, Brooklyn, owned by Joseph Kielbiowski and constructed in 1928. The building has maintained a clean record in recent years regarding both bedbug infestations and rodent issues, with all eight bedbug reports since 2019 showing zero affected units, and five consecutive rodent inspections between 2016 and 2025 passing without any issues.

However, the building has experienced some maintenance challenges, most notably a door/windown emergency complaint in July 2020 related to a vestibule door lock that resulted in HPD violations. Though this issue was resolved by April 2021, subsequent violations were issued in both 2021 and 2024 regarding the failure to file annual bedbug reports, showing some administrative oversight in compliance matters.

The most recent official inspection in April 2024 did not reveal any open violations, suggesting improved compliance with housing maintenance codes. While the building's historical data from 2019 to present shows proactive management in addressing both pest control and rodent prevention, the pattern of bedbug report violations in 2021 and 2024 indicates occasional lapses in administrative procedures, though no actual infestations occurred during these reporting periods. The building's general condition appears stable, with no major safety concerns reported in recent years, and all maintenance issues seem to have been addressed, though the timing of resolution can sometimes extend beyond initial reporting through various agency inspections and violations processes.
