91 Greenpoint Avenue, Brooklyn, NY 11222

91 Greenpoint Avenue is a four-story, six-unit building located in Greenpoint, Brooklyn, owned by Henryk Kielmanowicz and dating back to 1885. The property has experienced several significant events in recent years, most notably between early 2019 and early 2020. In February 2019, the building was subject to multiple Department of Buildings (DOB) violations, including failure to maintain the building in a code-compliant manner and unsafe construction practices during work in Apartment 5, with reports of fire stopping being removed from ceilings, walls, and floors.

These violations resulted in a stop-work order, though records show they were subsequently resolved. The building underwent several rodent control measures in late 2013 through 2014, with multiple bait applications recorded, though more recent inspections in 2018 and 2019 passed without issues. The property has maintained a clean record concerning bedbug infestations over the past seven years, with all annual filings between 2019 and 2025 reporting zero infested or eradicated units.

While the building's permit history shows several permits issued in early 2019 for electrical and plumbing work, the most concerning period appears to have been early 2019 when multiple violations and illegal work prompted enforcement actions. Since that time, there have been no recorded major violations or safety concerns, and the building has passed all recent rodent inspections. The consistent absence of pest issues in recent years, along with the resolution of 2019 violations, suggests improved maintenance practices, though prospective tenants should note the building's age and history of construction-related safety concerns.
