Augrented Insights Report for 505 Onderdonk Avenue

The 6-unit, 3-story New Law tenement at 505 Onderdonk Avenue in Ridgewood, owned by Joe Horodecki, was constructed in 1930 and has experienced several maintenance issues over the past decade. Most recently, in January 2025, there was a documented indoor sewage leak, though an investigation by the Department of Health and Mental Hygiene found no violations.

The building had multiple interconnected maintenance issues in October 2018, including problems with plumbing (bathtub/shower), water leaks (damp spots), unsanitary mold conditions, and flooring concerns, all of which were investigated by the Department of Housing Preservation and Development (HPD) but no violations were ultimately issued. The building has been subject to annual Bedbug Reporting requirements, with the most recent filings (2024-2025) showing no infested, eradicated, or re-infested units, indicating effective management of this potential issue.

There are two open violations from January 2018 related to broken tiles in bathroom 1L, and the building has consistently passed rodent inspections in 2016, 2017, and most recently in September 2024. While the property has experienced various maintenance challenges, most issues have been addressed without resulting in formal violations, and there have been no documented bedbug or rodent infestations in recent years.
