Augrented Insights Report for 452 West 23rd Street

The 4-story, 9-unit building at 452 West 23rd Street in Chelsea, built in 1856 and currently owned by Merryman Gatch, has experienced numerous maintenance and safety issues in recent months. As of July 2025, there are multiple open complaints including concerns about garbage storage, window frames, ventilation systems, and plumbing issues (boiler and sink) reported in June 2025.

The building has also faced recurring sprinkler system problems, with multiple safety complaints recorded in June 2025. Recent investigations have revealed multiple code violations, including illegal conversions (active complaint as of June 2025), unauthorized construction work, and plumbing modifications without proper permits. An alarming pattern of rodent activity has been documented through inspections in 2023-2025, with recent inspections in April 2025 and July 2025 failing for "Other Reasons." The property has a history of various maintenance issues requiring attention, including electrical problems (outlets and lighting), plumbing concerns (bathtub/shower), and general maintenance needs such as window repairs.

Previous Housing Maintenance Code (HMC) violations from late 2024 show multiple window-related issues in Apartment 1A that were subsequently certified as corrected in early 2025. Environmental Control Board (ECB) violations have been issued for various infractions, including a December 2024 violation for bathroom modifications in Apartment 1A and a January 2024 violation regarding exterior masonry conditions. While the building has demonstrated compliance with bedbug reporting requirements (showing zero infestations in recent years), the recent rodent inspection results and multiple open maintenance complaints suggest ongoing challenges with building upkeep and maintenance.
