818 Onderdonk Avenue, Queens, NY 11385
The 4-unit, 3-story New Law Tenement building at 818 Onderdonk Avenue in Ridgewood, owned by Stefanida Jovanovic, has experienced several significant maintenance issues in recent years, particularly related to safety systems. The most concerning cluster of violations occurred between October and December 2021 in Apartment 1C, involving multiple Class A violations related to door security and self-closing mechanisms, as well as fire safety concerns with defective smoke detectors and obstructed fire egress.
These violations were not fully resolved, with some remaining "Open" as of the last inspection. The building has also consistently had issues with door-related problems, with HPD responding to emergency complaints in September and November 2021 that resulted in issued violations. More recent building performance shows some ongoing challenges, with rodent activity reported in both September and November 2024 inspections, following a generally clean record of passed inspections between 2014 and 2017.
The property has maintained an apparently effective bedbug control program, with no reported infestations in the past four years, as evidenced by the filings from 2021 through 2025 showing zero infested or eradicated units. The building's 2024 bedbug inspection report is marked as both "Class A" and "Open" for failure to file the annual report, though the actual bedbug data shows no infestations. While issues have been relatively consistent over the years, the property's most significant violations appear to be related to safety systems and security, particularly in Apartment 1C, which have persisted despite multiple inspection cycles.
