502 Onderdonk Avenue, Queens, NY 11385

The 2-family house at 502 Onderdonk Avenue in Ridgewood, built in 1931 and currently owned by Oscar E Carpio, is a two-story building containing four units. The property experienced a significant cluster of maintenance issues in early 2019, with multiple complaints and violations documented between February and March of that year. These issues affected apartment 2R on the second floor and included problems with windows (frames and glass), flooring (particularly under the radiator), plumbing (sink issues), radiator maintenance, and both visible mold and pest infestation in the bathroom.

Several of these violations were classified as "B" (non-hazardous) and others as "C" (hazardous), with the building receiving multiple emergency housing maintenance code complaints including concerns about cooking gas and plumbing issues. Following a comprehensive inspection on March 14, 2019, numerous violations were documented, including problems with window balances, door hardware, floor conditions, and an unsanitary bathroom. While some of these violations were promptly closed by the end of March 2019, others remained open, particularly regarding floor repairs and bathroom conditions.

Notably, more recent inspections show consistent compliance with rodent control requirements, with the most recent inspection passing in September 2024. The property has maintained rodent-free status in all inspections since 2016, suggesting effective ongoing maintenance in this regard. As of the latest available data from 2025, there have been no recent major incidents or violations reported, indicating that the building's maintenance issues from 2019 were addressed, though some violations remained open for a period.
