Augrented Insights Report for 643 Bay Ridge Avenue

The 3-story, 6-unit New Law Tenement at 643 Bay Ridge Avenue, owned by Suetwah Chao and built in 1931, has experienced recurring maintenance issues, particularly with heat and hot water systems. Between December 2022 and February 2023, there were multiple complaints about no heat or hot water affecting the entire building, all classified as emergencies, though records indicate these were generally resolved.

The building also underwent several inspections and received multiple violations in April 2023, including issues with household items blocking hallways, a broken entrance lock, defective wood flooring, pest infestations (including roaches and mice), and various bathroom maintenance problems in the first-floor apartment (1F). Safety-related violations were recorded regarding carbon monoxide and smoke detectors, though these have since been addressed. The property has an active ECB violation from December 2018 regarding failure to comply with an order related to the filing of a Certificate of Correction, with a penalty of $1,250, and an earlier violation regarding unsafe storage of combustibles in the cellar.

While there were some serious maintenance issues in 2018 related to storage and unauthorized construction work in the cellar, these appear to have been resolved. Notably, there have been no reported bedbug infestations in the building since 2019, and the most recent bedbug reports from 2024 show no evidence of infestations. The building's recent history suggests a pattern of addressing issues after complaints are filed, though some problems, particularly regarding heating systems, have required multiple complaints before resolution.
