506 Graham Avenue, Brooklyn, NY 11222

506 Graham Avenue in Greenpoint is a three-story, three-unit residential building constructed in 1910, currently owned by Kwong Chiu and classified as an Old Law Tenement. The property has consistently faced rodent problems, with the most recent inspections in 2025 (July, April, and March) confirming rat activity despite multiple bait applications between March and June 2025.

The building has unresolved Housing Maintenance Code violations from 2022 through 2024 related to failure to file annual bedbug reports, and it sustained water damage to a front cellar gypsum wall in July 2021 that resulted in an active DOB violation. Between 2021 and 2022, there were several complaints about the building being vacant, open, and unguarded, though inspections found no violations at those times. A structure-related concern was reported in July 2021 regarding building shaking, which resulted in violations being served.

The building's maintenance history reveals ongoing pest control challenges, particularly with rodent activity, which has required multiple inspections and bait applications in recent years. The property has a pattern of documentation issues, as evidenced by the repeated bedbug report violations, suggesting potential lapses in compliance with housing maintenance requirements. The most concerning recent developments are the continued rodent activity into 2025 and the open violations related to bedbug reporting requirements, though all other complaints were resolved with no violations found at the time of inspection.
