Augrented Insights Report for 4801 5th Avenue

The 5-unit, 4-story New Law Tenement building at 4801 5th Avenue in Sunset Park, owned by Siu Lung Lam and dating back to 1924, has experienced several concerning patterns over recent years.

Most notably, there have been persistent issues with rodent and insect problems in the building's vicinity, with multiple Department of Health inspections between 2022-2024 documenting these infestations. Health Department records show at least eight service requests regarding food establishment issues, primarily related to rodent and insect problems, though most of these were ultimately administratively closed.

The building currently has open Housing Maintenance Code violations from 2021-2024 regarding the failure to file annual bedbug reports, and two significant incidents were recorded in October 2021 involving safety concerns: an Environmental Control Board violation for obstructed fire escape passageways and unauthorized construction work on the facade, though the first was resolved with a $1,250 penalty. More recent service requests in 2024-2025 include a closed food establishment letter grading inspection, while earlier rodent activity inspections in early 2022 confirmed rat presence.
