248 East 21st Street, Manhattan, NY 10010

The 10-unit, 5-story Old Law Tenement building at 248 East 21st Street in Gramercy, owned by Sau Chan, has experienced several significant maintenance and health-related issues over the past few years. Most recently, in June 2025, the building had confirmed rodent activity, following a pattern of similar issues with the Department of Health and Mental Hygiene recording violations in both 2023 and 2024.

The building has been under consistent rodent control measures, with multiple bait applications documented in 2023, though recent inspections in April and June 2025 also noted rat activity. There are two active bedbug-related violations from 2022 and 2023 regarding the failure to file required annual reports. The property has also faced challenges with heating and hot water service, with a December 2024 emergency complaint filed through HPD, though inspectors were unable to gain access to verify the reported issues.

Structural concerns were raised in 2023 when the building experienced shaking/vibration incidents, and a subsequent inspection revealed concrete deterioration on the roof area, resulting in a $6,250 fine. Building management has generally responded to most complaints, with several issues being resolved or closed, though the ongoing rodent presence remains a persistent problem. The building's maintenance history shows a pattern of both proactive rodent control measures and periodic health code violations, particularly relating to pest management and building maintenance compliance.
