AI summary · updated June 2026

370 East 23rd Street is a 4-story, 20-unit New Law tenement building constructed in 1931, currently owned by Asher Klein. The property has experienced significant maintenance issues in recent months, with multiple reports of water-related problems including slow leaks, plumbing issues, and indoor air quality concerns, notably a sewer odor in May 2025. The building has received several Housing Maintenance Code violations in 2024-2025, particularly in April 2025, when violations were issued related to ceilings, cabinets, and water leaks, though inspections showed some complaints did not violate housing laws. Historical data from 2019 indicates serious electrical safety concerns, including multiple Electrical Control Board violations regarding grounding, exposed wiring, and unsafe electrical equipment, though these were ultimately resolved. The building has maintained a clean record regarding bedbug infestations since 2019, with no reported cases in any dwelling units across multiple annual filings.

Previous inspection records reveal various maintenance issues, including problems with lighting, security (broken entrance door lock), and housekeeping standards. The property had active ECB violations in 2019 related to fire safety, electrical systems, and tenant protection notification requirements, though most were resolved. There were also violations regarding boiler inspection reporting that remained active as of 2019. Multiple complaints from 2019 regarding illegal conversion, excessive debris, and plumbing issues were recorded, along with housing maintenance violations for ceiling damage, window repairs, and other maintenance items. Recent complaints show a pattern of water-related issues and general maintenance concerns that may indicate ongoing building system challenges. While some historical violations suggest previous systemic maintenance issues, many have been resolved, and there have been no bedbug infestations in recent years, though the building's current maintenance record shows significant ongoing concerns.
