505 Ridgewood Avenue, Brooklyn, NY 11208

The three-story, three-unit tenement building at 505 Ridgewood Avenue in Cypress Hills, owned by Lidong Cao, has experienced several significant maintenance and safety-related events over the past few years. Most notably, in early 2023, the building experienced sewage-related issues, with both the Department of Health and Mental Hygiene and the Department of Housing Preservation and Development investigating complaints of unsanitary conditions, though no violations were ultimately issued in the DOHMH investigation. The building has a history of compliance issues requiring attention to safety systems, with multiple violations documented in 2019 alone, including problems with smoke detector maintenance, carbon monoxide detector requirements, and various necessary safety postings in common areas.

The property also faced administrative violations in 2019 regarding the proper posting of gas leak procedures and housing information guides. Prior to these issues, the building had documented a sewage-related complaint in 2023 and had previously maintained a clean record with respect to bedbug infestations, as evidenced by three consecutive annual reports (2020-2023) showing zero infested units, though violations were noted in 2021 and 2022 for failing to file annual bedbug reports. The most recent permits on record from 2020 show a job related to "EW" (possibly exterior work) that was issued and presumably completed.

The building's inspection and violation history indicates a pattern of safety-related concerns being addressed, though not always promptly. While recent bedbug reports (2022-2024) show no infestations, the property has experienced periodic maintenance challenges, particularly in 2019 when multiple safety notices were required but not properly posted. The 2023 sewage incidents, while resolved without violations, suggest ongoing infrastructure maintenance may require attention.
