556 Onderdonk Avenue, Queens, NY 11385

The two-family house at 556 Onderdonk Avenue in Ridgewood, owned by Fritz Guelly, has experienced several important maintenance and compliance issues since 2017. The building has ongoing concerns with its high-pressure inspection compliance, with six active violations as of September 2024 related to failures to file required internal and external high-pressure inspections for the years 2018-2023.

Although some violations from 2018-2020 were dismissed in February 2025, the current active violations represent a significant regulatory oversight. The building has faced several tenant comfort issues, particularly in early 2022 when complaints were made about heat/hot water problems affecting the entire building and cooking gas concerns; however, these complaints were either closed without violations being found or the Department of Housing Preservation and Development was unable to gain access for inspection.

Additionally, there was one instance of rat activity noted in July 2022, though subsequent inspections in 2023 and 2024 passed without any issues. While the building presents several compliance challenges, particularly with high-pressure inspection filings, it's worth noting that most recent rodent inspections have shown no significant problems. The building's age (constructed in 1931) and its two-story design are typical for the Ridgewood neighborhood.
