AI summary · updated June 2026

The two-story, three-unit residential building at 243-12 73rd Avenue in Douglaston, owned by Sang Chang, was constructed in 2006. The property has experienced several notable maintenance issues throughout its history, with the most significant occurring in March 2019 when multiple emergency complaints were filed regarding water leaks and mold conditions, though inspectors were unable to access the reported areas and no violations were issued at that time. A specific mold violation was later documented in the basement apartment, identifying a 5 square foot affected area in a closet. More concerning is an open mold violation from April 2024 related to bedbug reporting compliance, which follows a pattern of annual bedbug reporting violations dating back to 2021-2023, though the building's bedbug reports for those years indicate no infestations (with reports showing 0 infested, 0 eradicated, and 0 re-infested units). The building's most recent bedbug report filing from August 2023 shows consistent compliance with reporting requirements and demonstrates effective pest management, as no units were found to be affected during the 2021-2022 and 2020-2021 reporting periods despite the previous violations.
