403 Kosciuszko Street is a 4-story, 13-unit New Law Tenement building constructed in 1931, currently owned by Larry Hirscfield. The property has experienced several maintenance issues in recent years, with the most pressing current concern being two open complaints filed in June 2025 regarding ventilation system problems. Throughout 2023-2024, the building faced multiple heating system challenges, including emergency heat/hot water complaints in November 2023 and December 2024, with some requiring HPD inspection to confirm resolution. Apartment 2C has particularly documented issues, with multiple open violations as of 2024-2025 related to water damage, mold, plumbing, and bathroom conditions. Additional maintenance concerns have been noted, including a January 2025 violation for roach infestation in apartment 3A, various plumbing issues in December 2023, and electrical/appliance problems in October 2024.
Despite these issues, the building has maintained an active rodent inspection program, passing all inspections from 2020 through July 2025, and has reported no bedbug infestations in the last four reporting periods (2021-2024). Multiple housing maintenance code violations were issued in 2024, including concerns about smoke and carbon monoxide detector functionality in apartment 2C, the need for wall repairs, and various plumbing issues. The property management has generally addressed violations once issued, though some remain open as of the latest inspection dates in 2024-2025, including those relating to ventilation systems and specific conditions in apartments 2C and 3C.
