Augrented Insights Report for 648 Leonard Street

648 Leonard Street is a 4-story, 8-unit Old Law Tenement building in Greenpoint, Brooklyn, constructed in 1928 and currently owned by Christopher Karowowski. The building has experienced some pest management challenges over recent years, with notable rodent activity in 2022 leading to a Department of Health and Mental Hygiene inspection that found violations requiring follow-up inspections.

A subsequent compliance inspection in October 2022 resulted in passing grades, and the building's most recent rodent inspection in 2022 also passed. The property has maintained a consistently clean record concerning bedbug infestations, with official reports from 2019 through 2024 showing zero infested or eradicated units across all reporting periods.

The building has experienced relatively few major issues since 2019, with only one significant complaint on record regarding illegal hotel rooms in residential buildings in July 2022, though inspection attempts in October 2022 did not result in access to the unit. On the positive side, the building's permit history shows activity in 2020, with an electrical work permit issued. The property has demonstrated responsiveness to pest control inspections, passing subsequent rodent inspections after initial activity reports, suggesting proactive management of such issues when they arise.
