257A 20th Street, Brooklyn, NY 11215
The 3-unit, 3-story old-law tenement building at 257A 20th Street in Sunset Park, owned by Joseph Mariano and constructed in 1910, has maintained a consistent record regarding bedbug reporting and Housing Maintenance Code compliance over the past several years. Since 2021, the building has demonstrated effective pest management practices, with all five annual bedbug report filings (covering periods from 2019-2020 through 2024-2025) indicating zero infested units, zero eradicated units, and zero re-infested units.
The building experienced three Housing Maintenance Code violations between 2022 and 2024, all citing failure to file the required annual bedbug report, though all these violations have been resolved and classified as closed. The most recent bedbug report filing occurred in June 2025, covering the period from November 2023 to October 2024, continuing the trend of reporting compliance and confirming the absence of any bedbug infestations in the building during that period.
Despite the historical violations regarding report filing, it is noteworthy that these occurred during a period when the actual bedbug infestation rates in the building were consistently reported as zero. The property has shown a pattern of compliance with bedbug reporting requirements since 2021, with the most recent filing in June 2025 indicating no pest-related issues. The building's age (115 years) places it in the category of old-law tenements, which typically have specific preservation and maintenance requirements, though the current bedbug reporting compliance suggests active management of pest control protocols.
