3517 Avenue I, Brooklyn, NY 11210

The two-family residential building at 3517 Avenue I in Flatlands, owned by Cynthia Addison-Bernadine, has experienced several notable events over recent years. The most significant incidents occurred in late 2022 when emergency complaints were filed regarding safety concerns related to both smoke and carbon monoxide detectors.

The New York City Department of Housing Preservation and Development (HPD) investigated these complaints and, after inspections conducted between August and October 2022, found no violations, leading to the closure of both cases. More recently, in early 2025, there was an investigation into an alleged illegal conversion of the property, with the Department of Buildings documenting attempts to inspect the premises in March and July 2025.

However, access to the property was denied during these inspection attempts, and as of July 2025, the complaint remains listed as "Access Denied – 2nd Attempt" with no further resolution recorded. The building's history shows a generally reactive response to safety concerns, with authorities requiring multiple attempts to access the property for inspection purposes, particularly regarding the recent illegal conversion investigation.
