539 4th Street, Brooklyn, NY 11215

539 4th Street is a 4-story, 8-unit residential building located in Park Slope, Brooklyn. Built in 1920 and classified as a New Law Tenement, the building is currently owned by Lucas Joynt. The property has experienced several concerning pest control issues over recent years, most notably a cluster of rodent sightings in March and April 2021, during which multiple complaints were filed with the Department of Health and Mental Hygiene.

Follow-up inspections confirmed rat activity in both initial and compliance checks during this period. While there were no reported bedbug infestations during the 2019-2025 monitoring period, the building has received multiple Housing Maintenance Code violations related to bedbug reporting requirements between 2021 and 2024. The building also has significant outstanding Department of Buildings violations, with active citations issued between April and June 2023 for failure to file mandatory external low pressure inspections between 2018 and 2022, though one violation from 2019 regarding boiler inspection filing remains active as of this date.

These unresolved violations, combined with the historical rodent issues, suggest ongoing maintenance and compliance challenges. However, it should be noted that the most recent bedbug reports from 2023-2025 indicate no infestations, which could signal improved pest management practices. The building's age and history suggest these issues are not uncommon for a structure of this vintage in Brooklyn, though the frequency of violations and service requests warrants attention.
