Augrented Insights Report for 181 4th Avenue

181 4th Avenue is a four-story, three-unit residential building located in Park Slope, Brooklyn, owned by Ken Tu and constructed in 1920 as an Old Law Tenement. The property has experienced recurrent rodent issues, with the most recent inspections in 2025 (May and July) showing "Rat Activity," and previous instances of rat activity noted in 2019 (August), though several inspections from 2018-2019 resulted in "Passed" status.

The building has an open violation from 2024 requiring the annual bedbug report to be filed, and a similar violation from 2023, with ongoing violations for 2022 and 2021 regarding bedbug reporting requirements. Historical maintenance issues include a fire escape safety complaint in March 2020 that was inspected but resulted in no violations, and a concrete lintel repair violation in 2020 that was subsequently closed.

A sidewalk shed complaint from July 2019 was investigated and found to have no warranted violations. The building's maintenance record shows a pattern of rodent-related issues, with the most recent investigations occurring in 2025, suggesting ongoing pest control challenges that have persisted over multiple years despite some passed inspections in previous years. The property has consistently required attention to both rodent control and bedbug reporting compliance, indicating ongoing challenges with building maintenance requirements.
