Augrented Insights Report for 234 Underhill Avenue

The 234 Underhill Avenue property is a 3-story, 2-family house located in Prospect Heights, built in 1920 and currently owned by the Yock Yee Lee Trust. The building has experienced several significant maintenance and safety issues over its recent history, with the most pressing concerns originating from 2018 when multiple violations were cited in the 3rd-story apartment, including missing carbon monoxide detectors, smoke detectors, broken kitchen ceiling plaster, defective bathroom floor tiles, an faulty electrical outlet, and various ceiling paint issues. These violations remain open as of the latest available data.

The building underwent substantial renovation work between 2020-2022, during which time multiple construction-related safety violations were recorded, particularly in July 2021, when several enforcement actions were taken against contractors for safety compliance issues, including failure to maintain proper safety equipment measures, lack of guardrails, and inadequate site safety plans. These violations resulted in penalties totaling $15,000, though they were subsequently resolved. Recent inspections have shown consistent rodent control compliance, with all 2023-2025 inspections passing.

The building has maintained active permits throughout the renovation period, with multiple permits issued between 2019-2022 for various types of work including plumbing, alteration, and exterior work. The most recent building-related complaints (2020-2023) have been addressed through inspections, with no violations warranted at the time of inspection for boiler issues, crane concerns, and safety training compliance complaints. While the property has exhibited numerous maintenance and safety compliance issues over the past several years, most have been addressed through permitting and inspection processes, though the 2018 housing maintenance code violations in apartment 3 remain unresolved as of the latest data.
