141 Guernsey Street, Brooklyn, NY 11222

141 Guernsey Street is a 4-story, 8-unit New Law Tenement building located in Greenpoint and owned by Dorothy Karwowski. Built in 1928, this brick structure has experienced several maintenance issues over the past few years, with the most recent complaint regarding heat and hot water services occurring in February 2020, which resulted in a violation for excessively hot water (over 130 degrees) in apartment 1L.

The building has a documented history of maintenance challenges, particularly in 2019 when multiple violations were recorded, including issues with mold (emergency violation), wall conditions (paint/plaster), and various plumbing problems. Several of these violations were eventually resolved, including repairs to a defective kitchen sink connection, cabinet issues, and wall conditions. The property has maintained a consistent record of bedbug-free status over the past several years, with no reported infestations or treatment requirements from 2019 through 2025.

However, there were two rodent activity inspections in 2018 that indicated rat activity was present, suggesting occasional pest management challenges in the building's history. While the property has experienced various maintenance issues, most of the violations have been addressed, and the building has not had any major reported complaints or violations in recent years. The most recent inspections and reports have shown improved conditions, with no new violations or serious complaints recorded since 2020.
