422 4th Avenue, Brooklyn, NY 11215

The three-unit, three-story brownstone at 422 4th Avenue in Gowanus, owned by Jeff Li and built in 1901, has experienced persistent maintenance challenges over recent years, with particular attention required to rodent control and infrastructure maintenance. The building has demonstrated ongoing rodent presence, with multiple incidents reported between 2019 and 2024, though recent inspections in 2024 (most notably in December) have shown compliance with health department standards after bait applications and inspections throughout the year.

Notably, there was one serious rat sighting in August 2023 where violations were found, marking a particularly concerning period in the building's recent history. In addition to rodent issues, the building has faced various infrastructure challenges documented in 2019, including problems with water supply, damp spots, and plumbing fixtures, though these complaints were investigated and closed without violations being issued.

The property has been subject to repeated bedbug reporting requirement violations between 2021 and 2024, though recent filings indicate no infested units during the 2023-2024 and 2022-2023 reporting periods, suggesting improved conditions. A recent Local Law audit conducted in March 2025 issued a stop work order that was fully rescinded. While the building's maintenance history shows regular inspections and efforts to address identified issues, the recurring nature of certain problems, particularly rodent-related incidents and historical bedbug reporting violations, indicates ongoing challenges with building maintenance and pest control that require continuous attention.
