874 42nd Street, Brooklyn, NY 11232
The 16-unit, 4-story "New Law Tenement" building at 874 42nd Street in Borough Park, owned by Doris Konovitch, has experienced several notable issues in recent years, particularly in 2023 and 2025. Most concerning are recent violations related to flooring, with a flooring issue that remained unresolved through May 2025, and multiple safety and maintenance concerns in 2023 that included problems with smoke detectors, carbon monoxide detectors, water leaks, electrical lighting, and various paint/plaster issues.
The building's most significant unit appears to be Apartment A2, which has documented violations including water leaks in the bathroom, multiple issues with plastered surfaces and paint uniformity, electrical problems, and defective carbon monoxide detection equipment, though these violations were certified as corrected by June 2023. The building has a history of unsanitary conditions, with multiple complaints about mold in the spring of 2023, and safety concerns regarding smoke and carbon monoxide detectors. While there was a plumbing issue with a toilet in October 2023 that was resolved, the building also experienced a door frame issue in early 2025, though HPD determined this did not violate housing laws.
The property has maintained a consistent record of bedbug and rodent inspections, with no reported infestations since 2019 and a passed rodent inspection in January 2023. A Department of Buildings complaint from January 2023 regarding water retention and improper drainage could not be investigated due to access issues. The building's violation and complaint history, particularly in 2023 and 2025, suggests ongoing maintenance and safety compliance challenges, though many previous violations have been addressed and closed through proper procedures.
