Augrented Insights Report for 550 Onderdonk Avenue

This two-family house at 550 Onderdonk Avenue in Ridgewood, owned by Aimou Lin, has experienced significant construction-related activity and safety compliance issues between 2021 and 2022. The property underwent major alterations that generated multiple Department of Buildings (DOB) complaints, with the most concerning incidents occurring in late 2022 when multiple Construction Safety Compliance (CSC) violations were recorded, including a stop work order and oath violations.

The construction activities also resulted in several Environmental Control Board (ECB) violations related to safety protocols and debris management, with penalties totaling $2,500 during 2021-2022. Notably, there were multiple instances of improper scaffold maintenance and unsafe working conditions documented during inspections, though most violations were ultimately resolved. Since these construction periods, the building has maintained regulatory compliance through 2024-2025, with no recorded bedbug or rodent issues in recent inspections.

There was a notable pattern of failure to file external low-pressure inspection reports in 2023, though these violations were dismissed. The property has passed all recent rodent inspections between 2019 and 2024, except for a noted rat activity report in 2016. The building's construction permits from 2021-2022 indicate regular maintenance and construction oversight, with several permits issued for alteration and exterior work, suggesting ongoing property improvements.
