421 Ridgewood Avenue, Brooklyn, NY 11208

The two-family house at 421 Ridgewood Avenue in Cypress Hills, owned by Yue Feng Lin, is a 2-story, 6-unit building constructed in 1910. The property experienced a significant cluster of maintenance issues in 2018, primarily affecting first-story Apartment 1, where multiple violations were documented in April 2018, including water leaks in the bathroom ceiling, problems with plastered surfaces and paint on walls and ceiling, and the absence of a proper carbon monoxide detecting device - violations classified as B and C under the Housing Maintenance Code.

These violations have since been closed, but they indicate a period of concerning maintenance conditions. The building has maintained a generally good record since these incidents, with no documented housing maintenance code violations in the past five years (as of July 2025). The property underwent several permitted improvement projects in late 2018 and early 2019, as evidenced by multiple permit issuances under job number 321830248, covering various construction and plumbing work.

The building has successfully passed multiple rodent inspections between 2012 and 2017, indicating that pest management has not been an ongoing issue. A complaint regarding an unpermitted work situation was filed in July 2018, but the investigation in September 2018 found no violations. While the building experienced notable maintenance issues in 2018, the absence of recent violations and the completion of permitted work suggest improved maintenance conditions in recent years.
