8640 18th Avenue, Brooklyn, NY 11214

The three-story, two-unit Old Law Tenement building at 8640 18th Avenue in Bath Beach, owned by Lilan Wu, has experienced persistent and concerning issues over the past two years. Most notably, there have been multiple complaints regarding illegal conversions, with seven separate complaints filed between July 2023 and April 2025, though inspections were either unable to gain access or were marked as "2nd Final Attempt." The building currently has an active violation from June 2023 for failure to file the 2018 external low-pressure inspection documentation.

In addition to the conversion complaints, there have been two complaints regarding illegal storefront signage – one in June 2024 (which warranted no violation) and another in August 2023 (resulting in an Oath Violation). Of particular concern is a January 2025 complaint about an adult establishment that was assigned to the Mayor's Office of Special Enforcement.

On a more positive note, the building has maintained a pest-free environment, with the most recent bedbug reports (for the periods ending October 2023 and October 2024) showing no infested units, no eradication efforts required, and no instances of re-infestation. While the building's bedbug status is commendable, the persistent illegal conversion complaints and associated inspection access issues suggest ongoing concerns about unauthorized modifications to the property. The property was constructed in 1931 and has a current building class designation of Old Law Tenement, which typically relates to buildings constructed before the 1934 Multiple Dwelling Law.
