AI summary · updated June 2026

42 Sutton Street is a 6-unit, 3-story Old Law Tenement building in Greenpoint, built in 1940 and currently owned by Krystyna Zablocki. The building has undergone several inspections and faced multiple violations, though all have been resolved. Most notably, a comprehensive inspection in September 2018 revealed multiple safety-related issues that required attention, including problems with smoke and carbon monoxide detectors in apartment 3L, and several safety compliance issues in common areas such as missing signage for smoke detector requirements, carbon monoxide device requirements, and gas leak procedures. These violations were all certified as corrected by October 2018.

More recent building history shows consistent compliance with safety regulations, including a passed rodent inspection in September 2023. The building's bedbug reporting record is particularly notable for its perfect compliance, showing zero infestations or eradication efforts across all filing periods from 2018 through the most recent filing in December 2024. The most recent housing maintenance code violation, recorded in April 2021, concerned the annual bedbug report filing requirement, which has since been resolved. The building has maintained regular bedbug reporting since then, with all recent reports showing zero affected units, indicating effective pest management protocols.
