Augrented Insights Report for 1805 49th Street

The 38-unit, 4-story New Law Tenement building at 1805 49th Street in Borough Park, owned by Charles Knoll, has experienced numerous maintenance issues over the past few years, with the most significant and recurrent problem being lack of heat and hot water. Between December 2022 and January 2025, there were at least eight documented instances of heat/hot water outages affecting either individual apartments or the entire building, with complaints continuing into 2025 despite HPD's verification of some repairs.

Other notable maintenance concerns include a heavy water leak incident in December 2024 that resulted in violations, and ongoing issues with wall and ceiling paint/plaster conditions in January 2025. The building's violation history reveals several serious safety concerns, particularly in 2022 when Apartment B8 was found to have multiple violations including infestations of roaches and mice, lead-based paint hazards, and problems with smoke and carbon monoxide detectors.

The property has also faced ventilation system issues, with multiple illegal/improper vent/exhaust complaints from 2022 through 2025, and two active Environmental Control Board violations from 2023 related to unauthorized exterior vent installations, each with a $1,250 penalty. While the building has documented bed bug infestations in past reporting periods (2019-2022), recent filings for 2023-2024 indicate no current infestations. The property has an active Department of Buildings violation from 2021 regarding energy efficiency score display requirements.
