721 Dean Street, Brooklyn, NY 11238

721 Dean Street is a 3-unit, 3-story residential building located in Prospect Heights, Brooklyn. Built in 1910 and classified as a New Law Tenement, the property is currently owned by Deborah Rennie.

The building has experienced persistent challenges with pests, particularly rodents, as evidenced by multiple inspection results showing rat activity between 2018 and 2025, with the most recent inspection in May 2025 confirming current rodent presence. The property has also faced regulatory scrutiny from the Department of Health and Mental Hygiene, which issued violations in March 2021 related to rodent sightings, requiring follow-up inspections. Despite these ongoing pest control issues, the building has maintained a consistent record of compliance with bedbug reporting requirements over the past several years.

Between 2020 and 2024, all six annual bedbug reports filed showed zero infested units, zero eradicated units, and zero re-infested units, indicating effective management of this particular pest problem. While the building's housing maintenance violations have been relatively minimal, a notable violation was recorded in April 2024 regarding the failure to file the annual bedbug report, though this appears to have been resolved given the subsequent report filings. The property's rodent control efforts have included bait applications, with significant activity recorded in inspections throughout the past five years, suggesting ongoing challenges in achieving effective long-term rodent management.
