642 Humboldt Street, Brooklyn, NY 11222

The three-story, six-unit tenement building at 642 Humboldt Street in Greenpoint, owned by Jan Dabrowski, has experienced several notable building health and safety events over the past three years. Most concerning is a recent rodent issue that emerged in May 2023, when rat sightings were reported that resulted in health department violations, followed by a successful compliance inspection in August 2023.

The Department of Health and Mental Hygiene scheduled follow-up inspections in response to the initial rodent problems. On the positive side, the building has maintained a clean record regarding bedbug infestations, with six consecutive annual reports (from 2019 through late 2024) showing zero infested units, no eradication efforts needed, and no re-infestations.

The most recent 311 service request related to rodent problems in May 2023 has been resolved, though it did require official health department intervention, which suggests past pest control challenges. The building, constructed in 1931, falls under the "OLD LAW TENEMENT" classification, which typically includes buildings constructed before 1938 that are five or more stories high.
